How can a homeowner objectively compare sales claims from different solar reps about “free solar” and guaranteed bill elimination?

Homeowners can objectively compare solar sales claims by evaluating the Net Present Value (NPV) of each proposal, reviewing the binding Power Purchase Agreement (PPA) or lease terms, and calculating the guaranteed Production-to-Consumption Ratio.

1. Verify "Free Solar" Disclosures

"Free solar" is a marketing term for a zero-down Power Purchase Agreement (PPA) or lease. You do not own the system, and you must review the long-term financial obligations.

• Check ownership: Confirm you cannot claim the 30% Federal Investment Tax Credit (ITC). The solar company keeps it.
• Review escalator clauses: Identify the annual rate increase. Standard escalators range from 1% to 3.9%.
• Calculate total lifetime cost: Multiply the year-one monthly payment by 12, then compound it annually by the escalator percentage over 25 years.
• Evaluate transfer terms: Read the contract clause for selling your home. Buyers must qualify to assume the lease.

2. Audit "Guaranteed Bill Elimination" Claims

Solar panels cannot eliminate fixed utility connection fees, and production guarantees do not equal utility bill credits.

• Isolate fixed utility fees: Check your current bill for "customer charges" or "infrastructure fees." Solar cannot offset these.
• Locate the production guarantee: Look for the specific kilowatt-hour (kWh) guarantee in the contract text, not the slide deck.
• Check under-production remedies: Verify if the company pays cash or provides credits if the system underperforms.
• Review degradation schedules: Ensure the guarantee accounts for standard panel degradation, usually 0.5% per year.

3. Calculate Comparative Financial Metrics

To compare a zero-down PPA against a purchased system (cash or loan), calculate the true cost per kilowatt-hour.

PPA Effective Rate=Total Year 1 Payments Guaranteed Year 1 kWh Production PPA Effective Rate equals the fraction with numerator Total Year 1 Payments and denominator Guaranteed Year 1 kWh Production end-fraction P P A E f f e c t i v e R a t e=T o t a l Y e a r 1 P a y m e n t s G u a r a n t e e d Y e a r 1 k W h P r o d u c t i o n

Purchase Cost per Watt=Gross System Cost−Tax Credits/Incentives Total System Size in Watts Purchase Cost per Watt equals the fraction with numerator Gross System Cost minus Tax Credits/Incentives and denominator Total System Size in Watts end-fraction P u r c h a s e C o s t p e r W a t t=G r o s s S y s t e m C o s t−T a x C r e d i t s/I n c e n t i v e s T o t a l S y s t e m S i z e i n W a t t s

• PPA Rate vs. Utility: Compare the PPA Effective Rate directly to your current utility per-kWh rate.
• Escalator Impact: Plot the PPA rate out 25 years against projected utility inflation (historically 2-4% annually).
• Loan vs. Lease: Compare the total interest paid on a solar loan against the total escalated payments of a lease.

4. Normalize Technical Specifications

Sales representatives use different software to estimate production. Normalize their hardware specifications to ensure an apples-to-apples comparison.

5. Uncover Hidden Operational Blind Spots

• Roof warranty alignment: Ensure the solar installer covers roof leaks around penetrations for at least 10 years.
• True-up bill timing: Request your utility's Net Energy Metering (NEM) calendar to budget for annual balance bills.
• Removal and reinstallation costs: Check the contract for fixed fees if you must replace your roof during the solar term.

To help narrow down your quotes, could you share the state you live in , the system sizes (kW) quoted, or the first-year PPA rates you were offered?

The most objective way to compare solar pitches is to ignore the marketing language and force every rep to answer the same set of questions in writing.

Start by translating the sales claims

Ask every rep for the same 10 numbers

Request these in writing:

1. System size (kW DC)
2. Estimated annual production (kWh/year)
3. Estimated first-year utility bill after solar
4. Utility assumptions used
5. Net-metering or export-credit assumptions
6. Financing type (cash, loan, lease, PPA)
7. Interest rate or escalator
8. Total payments over the contract term
9. Production guarantee details
10. Assumptions about future electric usage

If a rep won't provide these, that itself is useful information.

---

Build a "solar truth table"

Create a spreadsheet with columns for each proposal and compare:

Many homeowners focus only on the monthly payment and miss the total lifetime cost.

---

Verify production independently

Ask every rep for the annual production estimate.

Then run the same address through:

A proposal that's dramatically higher than independent estimates deserves scrutiny. Production guarantees are only meaningful if the baseline estimate is realistic.

---

Examine the utility assumptions

This is where many "bill elimination" claims break down.

Ask:

• What utility rate plan was assumed?
• Is the utility offering true net metering, net billing, or another export-credit structure?
• What export value was used?
• What fixed monthly charges remain even if solar covers usage?

Solar economics depend heavily on how exported power is credited. Some utilities credit exports near retail rates, while others credit much less.

A useful test question:

"If export compensation falls by 25%, what happens to my projected savings?"

A good rep should be able to answer.

---

Demand the exact wording of any "guarantee"

For any guarantee, ask:

• Is it a production guarantee or a bill guarantee?
• Who pays if the guarantee is missed?
• How much do they pay?
• How is underperformance measured?
• What exclusions apply?
• Does excess production in one year offset shortfalls in another?

The fine print often matters more than the headline promise.

---

Watch for these red flags

• "You'll never have an electric bill again."
• "The government is giving away free solar."
• Refusal to provide assumptions in writing.
• Savings based on unusually high future utility-rate inflation.
• Failure to discuss fixed utility charges.
• Heavy emphasis on monthly payment instead of total contract cost.
• Escalator clauses that increase payments every year.

---

One simple question that cuts through the hype

Ask every rep:

"What will I pay over the next 25 years if your assumptions are exactly correct, and what will I pay if production is 10% lower than expected?"

The reps who can answer clearly with written numbers are usually the easiest to compare objectively.

If you're evaluating actual proposals, I can also help you build a side-by-side comparison and identify which assumptions are driving the differences.

Comparing sales claims from different solar reps—especially around “free solar” or “guaranteed bill elimination”—requires careful, methodical analysis. Reps often use similar words but different contract structures, financing mechanisms, and assumptions. Here’s a step-by-step framework to evaluate the claims objectively:

---

1. Understand the Financing Model

Solar offers that sound “free” usually fall into three categories:

⚠️ “Free” rarely means free—usually someone else (installer, lender, or investor) is covering upfront costs, and you pay indirectly.

---

2. Quantify “Guaranteed Bill Elimination”

When a rep promises your electric bill will go to zero:

1. Check assumptions:

   • Average sun hours at your location.
   • Roof orientation, shading, and panel efficiency.
   • Household electricity consumption.

2. Ask for a written estimate including:

   • Annual production in kWh.
   • Estimated savings per year.
   • Assumptions about your future electricity rate increases.

3. Verify guarantees:

   • Is the guarantee backed by the installer or insurance?
   • Are there penalties if production falls short?

Many guarantees only cover the system’s production, not your actual bill, which may include fixed fees from the utility.

---

3. Compare Offers Side by Side

Create a comparison table with exact numbers, not just claims:

Seeing all numbers together makes “free” or “guaranteed bill elimination” claims easier to compare objectively.

---

4. Check Incentives Separately

• Federal, state, and local incentives can dramatically reduce net cost.
• Confirm that the rep is correctly applying the Federal Solar Tax Credit (ITC) or local rebates.

---

5. Ask for Documentation

• Official proposals, energy production estimates, and guarantee terms.
• Do not rely on verbal claims—these can be ambiguous.

---

6. Do a Sensitivity Test

• How sensitive is the “zero bill” promise to:
  • Less sun than expected?
  • Increased household usage?
  • Utility rate changes?
• Run numbers yourself or with a third-party calculator (NREL PVWatts is reliable).

---

7. Consider a Third-Party Review

• Solar installers or energy auditors can provide independent estimates.
• Websites like EnergySage or PVWatts let you simulate expected production for your exact location.

---

✅ Bottom line: Focus on hard numbers and guarantees in writing, not marketing language. “Free” is rarely free, and “bill elimination” depends on assumptions about sun, usage, and utility rates. Comparing apples to apples requires a structured table of costs, savings, and guarantees.

---

If you want, I can make a ready-to-use spreadsheet template that lets you plug in numbers from each rep and instantly see which offer is truly best. It’s really handy for avoiding misleading claims.

Do you want me to create that template?

Homeowners can objectively compare solar sales claims by calculating the total contract cost, reading the fine print for hidden fees, and verifying production guarantees against local utility rules.

Ask for the Total Contract Value

• Request the cash price. Avoid looking only at the monthly payment.
• Calculate the lifetime cost. Multiply the monthly payment by the total months.
• Factor in the escalator rate. Check if payments increase by 2% to 4% annually.

Verify the "Free" and "Elimination" Claims

• Check the contract type. "Free solar" usually means a Power Purchase Agreement (PPA) or lease.
• Look for the monthly utility connection fee. Most utilities charge $10 to $30 just to stay connected.
• Review net metering rules. Ask if the utility credits power at a 1:1 retail rate or a lower wholesale rate.

Compare System Specifications

• Demand the exact system size. Compare total kilowatts (kW) across quotes.
• Check the hardware models. Ensure you compare identical panel and inverter brands.
• Look for degrading output terms. Panel production drops by about 0.5% every year.

Audit the Guarantees

• Distinguish hardware from production. A hardware warranty covers broken parts; a production guarantee pays you if the panels underproduce.
• Read the payout terms. Ensure underproduction is reimbursed in cash, not just future solar credits.

To help you sort through these proposals, tell me:

• What financing options (loan, lease, PPA) are the reps offering?
• What utility company services your home?
• What specific guarantees have they promised verbally?

I can help you pinpoint the exact red flags in your current quotes.

Homeowners can’t really “debate” solar sales claims effectively in real time—the key is to convert every pitch into the same standardized financial model and verify assumptions independently. Claims like “free solar” or “guaranteed bill elimination” are almost always marketing shorthand for financing structures and idealized usage scenarios, not literal guarantees. In fact, regulators and consumer guides consistently warn that “free solar” is misleading language for leases or power purchase agreements (PPAs), not zero-cost systems. nerdwallet.com +1

Here’s a practical way to compare different reps objectively.

---

1) Force every proposal into the same “apples-to-apples” format

Require each solar company to provide these on one page :

• System size (kW DC) and equipment list (panels + inverter models)

• Total installed cost (before incentives)

• Financing structure (cash, loan, lease, PPA)

• Interest rate, term, and any escalators

• Assumed annual production (kWh/year)

• Assumed utility rate escalation (%/year)

• Battery included? (yes/no, size)

• Warranty coverage (equipment + production guarantees if any)

If a rep can’t or won’t standardize this, their claims aren’t comparable.

---

2) Translate “free solar” into its real meaning

When a rep says:

• “Free solar”

• “No money down”

• “You’ll never pay a bill again”

You should translate it into one of these:

• Lease → You are renting the system; you still pay a monthly fee

• PPA → You buy electricity from their system, usually with yearly price increases

• Loan → You own the system, but still have a loan payment + utility bill

None of these are actually free. Even “no upfront cost” usually just shifts payment into long-term obligations. solar.com

---

3) Scrutinize the “bill elimination” claim mathematically

A legitimate comparison must separate:

A. What solar can control

• kWh produced annually

• Self-consumption vs export credits (net metering rules)

B. What it cannot control

• Nighttime usage

• Seasonal variation (winter/summer swings)

• Utility fixed charges (base fees, connection fees)

• Utility export credit rates (often not 1:1)

A common sales trick is assuming:

“100% offset = $0 bill”

But real bills often include unavoidable fixed charges, and export credits may be worth less than retail electricity.

---

4) Demand a side-by-side “no-solar vs solar” 25-year projection

Make them show BOTH scenarios:

Then subtract to get net savings or loss.

If they only show “monthly savings” instead of lifetime totals, that’s incomplete.

---

5) Independently verify production assumptions

Ask for:

• Solar irradiance assumptions (location-based data)

• System degradation rate (usually ~0.3–0.8%/year)

• Shading analysis report (not verbal estimates)

Then cross-check with independent tools like PVWatts (NREL) rather than trusting salesperson estimates.

---

6) Check incentive assumptions carefully

A major hidden distortion is incentives:

• Federal tax credit (if applicable) is often assumed fully usable

• Some reps assume future credits or outdated programs still exist

• Some include utility rebates that may have caps or expiration dates

If an incentive is required for “bill elimination,” the claim is fragile.

---

7) Treat “guarantees” as contract-bound, not verbal

If someone says:

• “Guaranteed bill elimination”

• “Performance guarantee”

You should look for:

• Exact compensation formula in contract

• What happens if production falls short

• Whether utility rate assumptions are locked or estimated

Most “guarantees” only guarantee system output—not your bill.

---

8) Red flags that usually mean the claim is unreliable

• Pressure to sign same-day

• “Government program” language

• Refusal to provide 25-year numbers

• Only showing monthly savings, not total cost

• Ignoring utility fixed charges

• Claims that all electricity use will be offset 1:1

Industry watchdogs consistently flag these as common deceptive patterns in solar sales. smartenergyusa.com

---

Bottom line

To objectively compare solar reps, you want to strip away marketing language and reduce everything to:

“Total lifetime cost of electricity under each option, using the same assumptions.”

If one proposal cannot be translated into that format, it’s not truly comparable—and the “free solar” or “bill elimination” framing is almost certainly doing most of the persuasive work.

---

If you want, I can give you a simple checklist or spreadsheet template you can use when reps come to your door so you can evaluate them in real time.

To objectively compare solar sales claims, ignore "free" narratives and compare total 25-year costs, price per watt (

WW

W

), and net present value using at least three independent quotes. Verify all verbal promises by requiring a written contract, checking equipment warranties, and verifying installer certifications through SEIA or NABCEP.

Key Objective Comparison Tactics:

• Deconstruct "Free Solar" (PPA vs. Ownership): "Free solar" usually means a Power Purchase Agreement (PPA) or lease, where you don’t own the system and pay a monthly fee, often with a 3% annual increase. Compare this to purchasing , where you own the equipment, receive the 30% federal tax credit, and build equity.
• Evaluate "Bill Elimination" (Net Metering): No system eliminates 100% of bills due to monthly grid-connection fees, unless you have a battery. Ensure the proposal uses current net metering rates for your utility and not inflated production figures.
• **Compare Price Per Watt (

$

/𝐖

):** Calculate this by dividing the total system cost by the wattage. This is the truest indicator of value, allowing comparison between companies with different equipment.

• Look Beyond the Sales Pitch:
• Verify Savings in Writing: Demand a detailed production report (e.g., PVWatts) that estimates annual solar generation, not just estimated savings.
• Check Credibility: Look for installers with NABCEP certification and check for complaints with the Better Business Bureau.
• Watch for Red Flags: Be cautious of reps demanding a signature immediately, claiming to be from your utility, or promising unrealistic "zero down" and high returns without transparent financing terms.

Key Metrics to Compare in Proposals:

1. Total Cost:

2. Price Per Watt:

3. Estimated Year 1 Production:

𝑘𝑊ℎ

4. System Warranty: (e.g., 25-year performance warranty)
5. Contract Type: PPA/Lease (no tax credit) vs. Purchase (30% tax credit).

Homeowners can’t reliably “judge” solar sales claims like “free solar” or “your bill will be eliminated” just by comparing quotes. The only objective way is to convert every pitch into the same set of hard financial assumptions and contract terms , then test whether the promises are actually mathematically and legally possible under your utility rules.

Here’s a practical framework that works in real comparisons:

---

1. First translate the sales language into what it actually means

Almost all “free solar” or “bill elimination” claims fall into one of three structures:

• Solar loan (you own system)

• Solar lease / PPA (you don’t own system)

• Hybrid financing with incentives rolled in

“Free solar” almost never means free panels—it typically means no upfront cost , not zero cost overall. solarreviews.com +1

So the first objective step is:

Ask every rep: “Which structure is this: loan, lease, or PPA—and who owns the system?”

If they won’t clearly label it, the comparison is already compromised.

---

2. Force every proposal into the same 6 numbers

To compare reps objectively, reduce everything to:

1. System size (kW)

2. Total cost (or total lease/PPAs payments over 20–25 years)

3. Monthly payment (starting + escalator rate)

4. Estimated production (kWh/year)

5. Your current utility rate assumptions

6. Net metering/export credit rules used

If any rep refuses to provide these in writing, their claim is not testable.

---

3. Stress-test the “zero bill” claim (this is where most pitches break)

A “guaranteed bill elimination” claim is only valid if ALL of the following are true:

• System size matches your actual annual usage

• Utility credits exports at or near 1:1 retail value

• No fixed utility charges remain

• Production matches real-world shading/weather losses

• Future rate increases don’t outpace system output

In reality:

• Utilities almost always have fixed charges you still pay

• Export credits are often lower than retail rates

• Solar output varies seasonally

So the objective question becomes:

“Show me the bill under winter months + night usage + utility fixed fees.”

If they only show an “average month,” the claim is incomplete.

---

4. Normalize all proposals into a 25-year total cost

This is the single most important comparison step.

For each offer compute:

Total cost = (monthly payment × months) + utility remaining charges − tax credits/incentives

Then compare against:

Projected utility cost without solar (25-year baseline)

If a rep claims “you’ll eliminate your bill,” but their contract still has:

• escalating payments

• residual utility charges

• system buyout clauses

…it will show up immediately in this comparison.

---

5. Check for “hidden dependency assumptions”

Sales claims often quietly depend on fragile assumptions:

• 1:1 net metering that may not exist in your utility territory

• Unrealistic production estimates (no shading loss, perfect orientation)

• Future electricity rate inflation used to “justify savings”

• Excess system sizing to make averages look favorable

Ask:

“What assumptions break this savings model?”

If they can’t answer clearly, the projection is not robust.

---

6. Convert “guarantees” into enforceable contract language

A critical distinction:

• Sales claim: “Your bill will be $0”

• Contract reality: usually “estimated production” or “savings projection”

Objective rule:

If it’s not in the signed contract, it is not guaranteed.

Many disputes happen because verbal guarantees are not enforceable.

---

7. Compare risk, not just savings

Two offers can show the same savings but very different risk:

Look for:

• who owns the system (you vs. company)

• what happens if roof leaks or system fails

• what happens if you sell the house

• escalation clauses in leases/PPA

A “cheaper monthly payment” can hide higher long-term obligation risk.

---

8. A simple scoring method homeowners can use

Assign each proposal a score (0–5) in these categories:

• Transparency of assumptions

• Contract clarity (no vague language)

• Realistic production modeling

• Total 25-year cost certainty

• Exit flexibility (selling home / payoff terms)

The “best” offer is rarely the one with the biggest savings claim—it’s the one with the fewest hidden assumptions and least dependency on perfect conditions.

---

Bottom line

To objectively compare solar reps:

• Ignore marketing phrases (“free,” “eliminate your bill”)

• Standardize everything into 25-year total cost + assumptions

• Stress-test under worst realistic utility conditions

• Treat anything not in the contract as non-existent

If you want, I can also show you a simple spreadsheet template homeowners use to normalize multiple solar quotes side-by-side.

To objectively compare solar sales claims, homeowners must look past "free" marketing and compare total net costs, specifically evaluating Price per Watt (

$

/𝑊

), financing terms, and system production guarantees. Obtain at least three quotes, check for in-writing guarantees, and beware of high-pressure tactics or vague "no-cost" promises.

Key Comparison Metrics & Tactics:

• **Compare

$

/𝑾

(Price per Watt):** This is the best way to compare system costs regardless of component differences.

• "Free Solar" = PPA/Lease: "Free" solar usually means a Power Purchase Agreement (PPA) or lease, where you don’t own the system. The rep is trying to get you to sign an agreement, often with a 3% annual rate increase.
• Guarantee Check: Ensure the sales rep provides all guarantees, including production, system maintenance, and roof repairs, in writing before signing any contract.
• Energy Use Analysis: Ensure quotes are based on your actual, full-year electricity usage, not just a low, enticing number.

How to Compare Quotes:

• Use EnergySage: Use a neutral platform to compare quotes from vetted installers, checking for reputation, experience, and certifications.
• Ownership vs. PPA: Compare total cost of ownership (cash/loan) against PPA/Lease. A loan often offers better long-term savings and ownership, while PPAs may have escalating, hidden costs.
• Check for 30% Tax Credit Eligibility: Only you, as the owner, can claim the 30% Federal Tax Credit, not the leasing company.
• Review Production Claims: Ensure production claims are backed by a reputable, independent solar design report, not just the salesman's software.

A good way to cut through “free solar” and “your bill will be $0 forever” claims is to force every salesperson into the same math-based comparison framework and make them prove outcomes under identical assumptions.

Most misleading pitches come from mixing different contract types (loan vs lease vs PPA) and hiding key variables like rate escalators, production assumptions, and utility offsets. Here’s how to evaluate them objectively.

---

1. First translate every offer into the same “cash flow language”

Every solar deal—no matter how it’s marketed—reduces to:

What you pay vs. what you would have paid your utility over 20–25 years

So ask each rep to put everything into:

• Monthly payment (starting year 1)

• Annual escalation (% increase per year)

• Contract length (typically 20–25 years)

• Assumed annual system production (kWh/year)

• Assumed utility rate inflation (%/year)

If they can’t or won’t standardize these, the comparison is already unreliable.

---

2. Re-label “free solar” correctly (this is where clarity starts)

“Free solar” almost always means one of these:

• $0-down lease (you rent the system)

• $0-down PPA (you buy electricity at a set rate per kWh)

In both cases:

• You do not own the system

• You do not get the tax credit

• You pay over time instead of upfront

This is explicitly how these offers are structured in practice energysage.com

So the real comparison is not:

“free vs paid solar”

It is:

“long-term contract vs owning an asset”

---

3. Demand the “bill elimination proof” (this is where most claims break)

If a rep says:

“We guarantee your electric bill will be eliminated”

Ask them to show:

A. Utility bill baseline assumption

• What current kWh usage are they assuming?

• Are they including seasonal variation (winter vs summer)?

B. System production guarantee

• Is it AC or DC rating?

• What degradation rate is assumed (panels lose output over time)?

• What happens in cloudy years?

C. What “bill” actually means

This is critical. “Bill eliminated” often excludes:

• Grid connection fees (you still pay utility base charges)

• Minimum service charges

• Import/export differences under net metering rules

So even with solar, most homeowners still have a utility bill.

---

4. Force normalization: “Show me cost per kWh over 25 years”

This is the single most objective comparison.

Ask each rep:

“What is my effective $/kWh over the full contract, including escalation?”

Then compare it to:

• Your current utility rate trajectory

• A conservative utility inflation assumption (often 2–5%/yr)

If they can’t provide this, they’re relying on marketing, not finance.

---

5. Run three side-by-side scenarios (this exposes hidden tradeoffs)

Have every rep model:

Scenario 1 — Worst solar year (low sun / underperformance)

• What happens to payments?

• Does your bill still drop?

Scenario 2 — Average year (their sales assumption)

• This is what they always show you

Scenario 3 — High utility inflation (real-world stress test)

• What if utility rates rise faster than expected?

• Does the contract still save money or lock you in below-market rates?

Good deals survive all three. Bad ones only look good in Scenario 2.

---

6. Identify “guarantees” that are not actually guarantees

Be cautious when you hear:

• “Guaranteed savings”

• “Your bill will be eliminated”

• “We predict X% savings”

These usually mean:

• They guarantee system performance assumptions , not your total utility outcome

• Or they compare against a inflated utility baseline

A real guarantee would specify:

total out-of-pocket cost vs utility over full term under defined assumptions

Very few reps can do that cleanly.

---

7. Check who owns what (this changes everything financially)

Ownership determines incentives:

• Lease/PPA (TPO models) : provider owns system, keeps incentives, you buy energy now.solar

• Loan/cash purchase : you own system, you keep tax credits and upside

This matters because “free solar” often shifts value to the company while simplifying your entry cost.

---

8. One simple rule that catches most bad deals

If you want a quick filter:

If the deal depends on “utility rates will definitely rise faster than your contract escalator,” it’s a projection, not a guarantee.

---

Bottom line

To compare solar reps objectively, you’re really doing three things:

1. Converting every pitch into $/kWh over 25 years

2. Standardizing assumptions (usage, production, inflation)

3. Stress-testing outcomes beyond the salesperson’s “average year” model

If you want, you can share two actual quotes (numbers only), and I can normalize them into a side-by-side “true cost over time” comparison.

To objectively compare solar sales claims, homeowners must look past "free" marketing and analyze the price per watt ($/W) , contract type (ownership vs. PPA), and warranty terms. "Free" usually means a Power Purchase Agreement (PPA), where you pay for power, not the system, which can have lower long-term savings. Always obtain at least three quotes on an apples-to-apples basis and check for [NABCEP] certification.

How to Compare Solar Proposals Objectively

• Ignore the Total Cost Gimmicks: Focus on the cost per watt ($/W) , which is the total cost divided by the system's size in watts.
• Demand Written Promises: If a representative promises guaranteed savings or bill elimination, ask for it in writing in the contract.
• Understand the "Free" Solar Myth: "No cost" or "free" solar often refers to a PPA or lease. You do not own the panels, you do not get the 30% federal tax credit, and your savings might be lower over time.
• Evaluate Annual Escalators: If you choose a PPA or lease, check for an annual price increase ("escalator"). A 3% annual increase can double your rate in 25 years.
• Verify Production Estimates: Ensure the promised production matches your actual energy usage. Some reps inflate production numbers to make savings look better.
• Compare Warranties: A 25-year manufacturer warranty is industry standard. Ensure they cover the system’s energy production, not just the panel equipment.

Warning Signs of Unrealistic Sales Pitches

• High Pressure: Salespeople insisting you must sign immediately to get a "special deal".
• Utility Impersonation: Reps claiming to be from the state or your utility company to trick you into a meeting.
• Hidden Costs: Unquoted costs like main panel upgrades, roof repairs, or site preparation.

For the most accurate assessment, compare quotes using EnergySage to see how different equipment and financing options affect your investment.
