When two solar proposals have roughly the same system size, the contract terms can matter more than the panel brand or a small difference in price. I’d compare these in roughly this order:
Compare the cash price, financed principal, and total amount paid over the life of the loan.
Look for:
A low monthly payment can conceal a much higher total cost. The FTC specifically recommends comparing financing costs, payment changes, fees, and loan length.
This is one of the most important differences between otherwise similar proposals.
Don't compare just “10 kW vs. 10 kW.” Compare the contract's guaranteed annual kWh production.
Ask:
A production guarantee is meaningful only if the contract specifies the remedy when production falls short.
Example: Company A guarantees 12,000 kWh/year while Company B merely estimates 12,500 kWh/year. I'd generally put considerable weight on A's contractual guarantee rather than B's higher projection.
Separate the warranties into panels, inverter(s), battery (if applicable), and workmanship.
Compare:
Don't assume “25-year warranty” means everything is covered for 25 years. Warranty coverage and claim procedures can differ substantially.
This deserves its own line item.
Ask exactly what happens if:
Also determine who pays for panel removal and reinstallation during a future roof replacement. The FTC specifically recommends comparing what happens if roof repairs are needed after installation.
Solar contracts can complicate a home sale, particularly leases and PPAs.
Check whether the buyer can:
Also check whether the contract creates any lien or other property-related obligation. DOE notes that third-party-owned systems can require additional steps when ownership of the home changes.
Look closely at what happens before installation.
You want to know:
Get every salesperson promise into the written contract. The FTC advises homeowners to make sure the written agreement matches representations made during the sales process.
This is where seemingly identical bids can diverge.
Compare whether each company includes:
The FTC recommends ensuring that the quoted installation cost includes applicable building and electrical permit fees and other installation costs.
This is especially important with leases and PPAs.
Look for an annual escalator such as 2.9% or 3.5%. Compare the actual payment in years 1, 5, 10, 15, and 20—not merely today's payment.
Also check whether maintenance or other charges can increase.
The contract should clearly state who receives each incentive.
For an owned system, determine what you are actually entitled to claim. For a lease/PPA, the system owner generally receives the applicable tax benefits and incentives.
Be particularly careful with sales presentations that treat a tax credit as an immediate guaranteed reduction in your purchase price.
A 25-year warranty isn't very useful if the company providing the workmanship warranty disappears in three years.
Compare:
DOE recommends checking installer credentials and comparing multiple installers.
If I were choosing between two contracts, I'd make a spreadsheet with these rows:
| Term | Company A | Company B |
|---|---|---|
| System size (kW) | ||
| Guaranteed annual production (kWh) | ||
| Expected annual production | ||
| Cash price | ||
| Total financed amount | ||
| APR | ||
| Loan term | ||
| Total payments | ||
| Panel warranty | ||
| Inverter warranty | ||
| Workmanship warranty | ||
| Production guarantee remedy | ||
| Roof-leak coverage | ||
| Roof removal/reinstallation | ||
| Maintenance included? | ||
| Panel degradation assumption | ||
| Escalator | ||
| Cancellation terms | ||
| Change-order rights | ||
| Transfer/payoff terms when selling | ||
| Lien/UCC/property obligation | ||
| Permits/interconnection included? | ||
| Electrical/roof upgrades included? | ||
| Who receives incentives/RECs? |
The biggest red flags: a contract that doesn't guarantee production despite making strong savings claims, vague warranty language, an escalating payment structure you haven't modeled, large undisclosed fees, difficult home-sale transfer provisions, or pressure to sign before you can review the agreement.
If you have the two actual solar proposals/contracts, you can paste or upload them here and I can build a line-by-line comparison and tell you which terms are materially better/worse, including the fine print that a salesperson may gloss over.

Compare:
A lower monthly payment does not necessarily mean a lower-cost system.
Make sure you are comparing the same type of agreement:
Ownership affects:
This is one of the biggest long-term differences.
Compare:
A contract that starts cheaper can become more expensive if it has a high escalator.
Do not compare only the panel size (kW). Compare expected electricity production (kWh).
Look for:
A larger system is not always better if the production estimate is aggressive.
The contract should identify:
Avoid agreements where equipment can be substituted without your approval.
Separate the warranties:
Pay attention to who is responsible for labor costs if equipment fails.
Compare:
A vague promise to “maintain the system” is less valuable than specific service obligations.
This is easy to overlook.
Check:
Solar contracts can affect future home sales if the transfer process is difficult.
Look for:

When two solar proposals have roughly the same system size, the contract terms can matter more than the panel count. The biggest things I’d compare are:
| Contract term | What to compare | Why it matters |
|---|---|---|
| 1. Total price | Cash price, financing amount, dealer/origination fees, permits, electrical work, taxes, and any add-ons | A “lower” monthly payment can hide a much higher total cost. |
| 2. Expected production | Guaranteed annual kWh, degradation assumptions, and exactly what happens if production falls short | A 10-kW system isn't necessarily equivalent to another 10-kW system if the production estimates differ. The FTC specifically recommends comparing promised output and remedies for underperformance. consumer.ftc.govconsumer.ftc.gov |
| 3. Production guarantee | Is it actually guaranteed? How is a shortfall calculated? Cash credit, replacement power, or nothing? | This can be substantially more valuable than a generic “25-year panel warranty.” |
| 4. Equipment warranties | Panel, inverter, battery (if applicable), and workmanship warranties; who actually honors each one | Look for both length and coverage, including whether labor and replacement costs are included. consumer.ftc.govconsumer.ftc.gov |
| 5. Roof warranty | Roof penetrations, leaks, roof damage, and who pays to remove/reinstall panels if the roof needs replacement | This is an easy-to-miss long-term cost. |
| 6. Maintenance & repairs | Who monitors the system, diagnoses failures, pays labor, and replaces failed equipment | Don't assume a manufacturer warranty means the installer covers labor. |
| 7. Financing terms | APR, loan term, upfront payment, fees, payment schedule, prepayment penalty, and total amount repaid | Compare total dollars paid, not just the monthly payment. If there's a solar loan, ask specifically about financing/dealer fees. |
| 8. Escalator | Whether payments or PPA rates increase annually and by how much | Particularly important for leases and PPAs; some contracts have predetermined annual increases. www.consumerfinance.gov |
| 9. Cancellation rights | Cancellation window, deposits, cancellation fees, and what happens if financing/permits aren't approved | Get this in writing before signing. The FTC recommends paying attention to cancellation policies and hidden fees. consumer.ftc.govconsumer.ftc.gov |
| 10. Installation obligations | Start/completion dates, permitting, utility interconnection, inspections, and who pays for unexpected electrical/roof work | You want a clear definition of what's included versus a potential change order. |
| 11. Ownership & incentives | Who owns the system, who receives applicable incentives/RECs, and what happens if incentives change | Ownership is particularly important when comparing purchase vs. lease/PPA arrangements. consumer.ftc.govconsumer.ftc.gov |
| 12. Selling the house | Can you transfer the agreement? Is there a transfer fee? Must the buyer qualify? Can the system be removed? | A long solar contract can complicate a home sale. The FTC specifically recommends checking transfer requirements and costs. consumer.ftc.govconsumer.ftc.gov |
| 13. Early termination | Buyout formula, removal costs, transfer costs, and any other termination charges | Especially important for leases/PPAs, which can run 15–20 years or longer. www.consumerfinance.gov |
| 14. System specifications | Exact panel/inverter models, battery model, mounting equipment, and promised design | “10 kW solar system” isn't enough to identify what you're actually buying. |
| 15. Who is responsible | Installer vs. salesperson vs. financing company vs. equipment manufacturer | Know exactly who you call when something breaks and who has the contractual obligation to fix it. |
If the systems are genuinely comparable, I'd focus on:
1. Total 20–25 year cost
2. Guaranteed production and compensation for shortfalls
3. Workmanship/roof warranty and who pays labor for repairs
4. Financing terms, including hidden/dealer fees and total repayment
5. What happens if you sell the house or want out early
One particularly important distinction: a manufacturer's 25-year panel warranty is not the same thing as a 25-year installer warranty or a production guarantee. Read the actual remedy—replacement panel, labor, lost-production payment, etc.—rather than relying on the headline warranty period.
Also, make sure every promise made by the salesperson appears in the contract/proposal. The FTC advises getting important promises in writing rather than relying on verbal representations.
If you paste the two solar proposals/contracts (you can redact personal information), I can compare them term-by-term and flag which differences actually matter financially.
When two solar proposals have **similar system sizes**, don’t focus on panel count or the headline monthly payment. Compare the **contract terms and risk allocation**. The biggest differences are often buried in the fine print. ### The 10 terms I’d compare first | Contract term | What to compare | Why it matters |
When two solar proposals have similar system sizes, don’t focus on panel count or the headline monthly payment. Compare the contract terms and risk allocation. The biggest differences are often buried in the fine print.
| Contract term | What to compare | Why it matters |
|---|---|---|
| 1. Total price | Cash price, financing amount, dealer/origination fees, permits, electrical work, taxes, etc. | A low monthly payment can hide a much higher total cost. |
| 2. Financing terms | APR, term, payment schedule, upfront payment, fees, prepayment rules, and whether the payment changes | Compare total dollars paid, not just the monthly payment. |
| 3. Escalator | Whether payments increase annually and by how much | Especially important with leases/PPAs. Some PPAs use annual escalators; EPA notes they can commonly be 1–5%. www.epa.gov |
| 4. Production guarantee | Guaranteed annual kWh, measurement period, degradation assumptions, and exactly what compensation you receive for shortfalls | A 10-kW system isn't necessarily equivalent to another 10-kW system. The contract should address what happens if promised production isn't achieved. consumer.ftc.gov |
| 5. Equipment warranties | Panel, inverter, battery (if any), workmanship, roof penetrations, and labor coverage | Look beyond "25-year warranty." Find out who actually pays for labor and service calls and how claims are handled. consumer.ftc.gov |
| 6. Maintenance & repair responsibility | Who monitors the system, diagnoses failures, removes/reinstalls panels, and pays for repairs | A manufacturer's parts warranty doesn't necessarily mean the installer will cover labor. |
| 7. Roof responsibility | What happens if you need a roof repair/replacement during the solar contract | This can become a major unexpected expense. The contract should spell out removal and reinstallation costs. consumer.ftc.gov |
| 8. Cancellation/termination | Cancellation window, termination fees, financing cancellation, and what happens if permitting or interconnection fails | Pay particular attention to clauses allowing the company to retain deposits or charge substantial termination fees. |
| 9. Home sale/transfer | Whether the system/loan/lease/PPA can transfer to a buyer and what the buyer must qualify for | A long solar obligation can complicate selling or refinancing. FTC specifically recommends comparing transfer requirements and fees. consumer.ftc.gov |
| 10. What happens at the end | Ownership, removal, renewal, buyout price, or continued payments | A 20–25-year contract can have very different end-of-term outcomes depending on the agreement. |
1. The actual equipment and design.
Even if both systems are, say, 10 kW, compare the panel model, inverter architecture, battery, expected annual production, shading assumptions, and roof layout. DOE notes that production depends on factors beyond system size, including roof orientation, pitch, shading, and sunlight.
2. The utility/interconnection assumptions.
Look at what each proposal assumes about your utility rate structure and credits for excess generation. Don't accept a savings projection at face value if it depends on aggressive assumptions about future electricity-rate increases. The FTC specifically cautions that future utility rates are difficult to predict.
I'd make each company fill in these numbers in writing:
My rule of thumb: if one company's proposal is cheaper but has a weaker production guarantee, narrower workmanship coverage, unclear roof-removal responsibility, or expensive exit terms, the "cheaper" system may actually be the riskier deal.
Also, get the entire contract and financing agreement before signing, not just the salesperson's proposal. The FTC recommends taking time to review the full agreement and making sure the written terms match what the salesperson promised.

When you are comparing two solar quotes with the same system size, the hardware might look identical, but the contract terms can make a massive difference in your long-term savings, financial safety, and peace of mind.
Here are the most important contract terms and variables a homeowner should compare side-by-side:
If you'd like, share the payment type (cash, loan, or lease/PPA) and state you are in, and I can tell you what specific red flags or legal caps to look out for in your contract.
If the two proposals have roughly the **same system size**, don't choose based primarily on panel wattage or the headline price. The biggest differences are usually buried in the contract. Here are the terms I'd compare, roughly in this order: | Contract term | What to compare | What I'd favor |
If the two proposals have roughly the same system size, don't choose based primarily on panel wattage or the headline price. The biggest differences are usually buried in the contract.
Here are the terms I'd compare, roughly in this order:
| Contract term | What to compare | What I'd favor |
|---|---|---|
| 1. Total price / financing cost | Cash price, loan amount, dealer/origination fees, interest rate, total payments, and any required down payment | Lowest all-in cost, not merely the lowest monthly payment |
| 2. Energy-production guarantee | Guaranteed annual kWh, how production is measured, length of guarantee, and compensation if production falls short | A specific production guarantee with meaningful compensation |
| 3. Equipment warranty | Panel, inverter, battery (if applicable), and mounting-system coverage; parts and labor | Longer, comprehensive coverage with a clear claims process |
| 4. Workmanship warranty | Roof penetrations, wiring, leaks, installation defects, etc. | Long workmanship coverage backed by the installer |
| 5. System degradation | Expected production decline over time and whether the production guarantee accounts for it | Lower degradation and a guarantee that reflects actual long-term output |
| 6. Maintenance & repairs | Who monitors the system, diagnoses failures, pays for service calls, replacement labor, shipping, etc. | Installer/provider bears most routine repair costs |
| 7. Roof obligations | Who pays if a roof repair/replacement requires removing and reinstalling panels | Explicit removal/reinstallation coverage or clearly defined pricing |
| 8. Cancellation rights | Cancellation period, conditions, deposits, and penalties after permits or equipment orders | Flexible cancellation with limited penalties |
| 9. Escalator | Particularly important with a lease/PPA: annual increase in your payment or $/kWh | No escalator is preferable; otherwise, the lowest fixed escalator |
| 10. Early termination | What happens if you want out before the contract ends | Low/no termination penalty and clearly defined buyout |
| 11. Home sale / transfer | Whether the agreement can be transferred to a buyer, whether the buyer must qualify, and transfer fees | Easy transfer with no onerous buyer requirements |
| 12. Ownership of incentives | Who receives tax credits, rebates, renewable-energy certificates, etc. | Make sure the contract matches your understanding of who gets them |
| 13. Permitting & interconnection | Who handles permits, utility approval, inspections, and what happens if approval is denied/delayed | Installer handles the process and bears clearly defined responsibility |
| 14. Change orders | Circumstances allowing the company to increase the price after signing | Fixed price except for specifically defined homeowner-requested changes |
| 15. Installation timeline | Estimated start/completion dates and remedies for unreasonable delays | Concrete milestones and meaningful obligations on the installer |
The FTC specifically recommends comparing system output, total installation costs, production guarantees, equipment warranties, workmanship warranties, ongoing costs, repair responsibilities, escalation clauses, early-termination provisions, and home-sale/transfer provisions.
1. Production guarantee vs. "estimated production."
A proposal saying "your system should produce 12,000 kWh/year" is very different from a contract guaranteeing a minimum amount and specifying what the company owes you if it doesn't. Make sure you understand the measurement period, exclusions (shade, outages, utility problems, etc.), and remedy.
2. Warranty isn't necessarily the same as service.
Ask: If an inverter fails in year 12, who diagnoses it, who supplies the replacement, who pays the labor, and how long do I wait? A manufacturer's equipment warranty may not mean the installer will provide free labor. The FTC recommends looking at both coverage and the claims/repair process.
3. What happens when you sell the house?
This can be particularly important with a 20-year lease or PPA. Determine whether the buyer can assume the agreement, whether they must qualify for credit, whether there's a transfer fee, and whether you have a buyout obligation.
Ask both companies to give you a one-page, apples-to-apples summary showing:
Cash price → financing cost → guaranteed annual kWh → 25-year expected production → warranties → repair responsibility → annual payment changes → cancellation/buyout → roof work → home-sale transfer.
Then compare the actual contracts against that sheet. If a salesperson promised something that isn't in the contract, don't assume the promise counts—get it written into the agreement.
