A solar quote needs five things: the system with named equipment, a production estimate with its shading assumption, the total price with price per watt, financing options side by side, and warranty terms with a next step and expiry date. Put price, monthly payment, year-1 production and savings on page 1.
Most solar deals are decided by the quote, not the roof. A homeowner who holds two or three quotes at the kitchen table compares documents, and the document that is clear, itemized and easy to act on has the advantage. This guide covers pricing, the checklist every quote needs, layout, financing, follow-up and the mistakes that cost margin. It is written for US residential installers and EPCs, and the same structure carries over to other markets.
Key takeaways
- Price from your own project costs first, then choose cost-plus or value-based pricing for the lead in front of you.
- Name the exact equipment, state the shading assumption and show the price per watt.
- Show cash, loan, lease and PPA side by side, with any loan fee on its own line.
- Put an expiry date and a clear next step on the quote, then follow up on a fixed schedule.
The Solar Quote: Your First Impression
Homeowners judge your company by the first document you send. Before they meet your crew or read your reviews in depth, they hold your quote next to the others. It does more selling than a doorstep pitch because it stays in the house after you leave.
A quote signals four things at a glance:
- Accuracy: the production number looks modeled, not guessed.
- Transparency: the price breaks into line items the customer can question.
- Professionalism: consistent branding, correct grammar and named equipment.
- Staying power: warranty terms from a company that will answer the phone in year 9.
Put four numbers where the customer finds them at once: total price, monthly payment, year-1 production and the savings estimate. If they sit on page 2, the customer has to hunt for them, and a competitor’s quote that shows them on page 1 reads as the more confident one.
Your quote is also read by people you never pitched: a spouse who missed the appointment, a neighbor who knows solar, a cautious parent. Write for that second reader, the one you cannot talk to. A practical test is to email the quote to yourself and open it on a phone. If the four numbers need zooming or a second page, restructure.
There is a difference between a quote and a proposal. A quote prices a job; a proposal sells a project. The strongest residential documents do both, which is why teams move from spreadsheets to solar proposal software that merges design data with pricing.
Check your template for tax-credit language. The IRS states that the 30% Residential Clean Energy Credit applies to property installed from 2022 through December 31, 2025, and that the credit is not available for property placed in service after December 31, 2025. A quote that nets out a 30% federal credit for a system placed in service in 2026 is wrong, and it makes the customer doubt every other number. Fix the template first.
What Every Solar Quote Must Include
A complete quote answers the questions the customer will ask anyway. Answer them first, on your terms. Use this as a checklist, and keep it as your solar quote template.
| Element | What to show | Why the customer checks it |
|---|---|---|
| System size and layout | Size in kW DC, panel count, and the panel placement on an image of the customer’s roof | Proves the roof was measured, not averaged |
| Named equipment | Exact module and inverter models with wattage and efficiency, not “or equivalent” | Lets the customer verify the price and specs online |
| Production estimate | Year-1 kWh with the shading assumption visible | Shows where the savings figure comes from |
| Total price and price per watt | Gross price, price per watt and enough line items that the number looks built | Lets the customer compare against other quotes on the same basis |
| Financing options | Cash, loan, lease and PPA with monthly payments | Moves the comparison from price to fit |
| Timeline | Milestones from signature to permission to operate, in your own realistic terms | An honest timeline beats a promise you cannot keep |
| Warranty terms | Module, inverter and workmanship warranties as written by each issuer, plus any production guarantee you stand behind | Separates what the manufacturer covers from what you cover |
| Next step and expiry date | E-signature link, site survey scheduling, deposit amount and a date until which the price holds | Turns interest into a decision and gives follow-up a reason to exist |
Three notes on the checklist:
- Production. Shade is where production estimates go wrong. Model it with solar shadow analysis software rather than applying a flat loss figure and hoping. Pair the kWh figure with a savings model from the generation and financial tool so the customer sees bill impact in currency, not just energy units.
- Warranty. Quote each warranty from the document that issues it, and do not invent a duration. If your own workmanship warranty is shorter than the manufacturers’ terms, say so plainly.
- Version control. Put a quote ID and issue date on every page. When a customer replies three weeks later holding competing bids, you need to know which equipment and pricing they are looking at.
Pricing Strategy: Cost-Plus vs. Value-Based
Your pricing method sets your margin before the customer negotiates. For a deeper look at the business side, see the solar pricing strategy hub.
Cost-plus pricing starts with true project costs and adds a margin. Calculate it for every job, even if you never show it. If you do not know your cost per installed watt, you do not know your margin.
The table below is a hypothetical 8 kW system. The inputs are placeholders: replace each line with your own costs.
| Line item | Hypothetical cost |
|---|---|
| Modules (8,000 W at $0.30/W) | $2,400 |
| Inverter and electrical | $1,800 |
| Racking and balance of system | $2,200 |
| Labor (3-person crew, 2 days) | $3,200 |
| Permits, interconnection and inspection | $1,500 |
| Sales and marketing allocation | $2,500 |
| Overhead (office, insurance, vehicles) | $3,400 |
| Total project cost | $17,000 |
| Quote price at a 20% margin on price ($17,000 / 0.80) | $21,250 |
| Margin in dollars ($21,250 x 0.20) | $4,250 |
| Quote price per watt ($21,250 / 8,000 W) | $2.66/W |
Arithmetic check: 2,400 + 1,800 + 2,200 + 3,200 + 1,500 + 2,500 + 3,400 = 17,000. A 20% margin on price means cost is 80% of price, so price is 17,000 / 0.80 = 21,250, and the margin is 21,250 - 17,000 = 4,250, which is 20% of 21,250.
Margin and markup are different numbers. The same $4,250 is a 20% margin on price but a 25% markup on cost (4,250 / 17,000). Adding 20% to cost would give $20,400 and only a 16.7% margin (3,400 / 20,400). Decide which one your team means before quoting.
Soft costs such as sales, permitting and overhead sit inside the base cost, not outside it. Installers who price hardware plus labor and call the rest profit find the margin was fictional. For a market benchmark, EnergySage’s cost page says systems average about $2.60 per watt before incentives and lists state averages that differ widely, for example $2.26/W in Arizona and $3.77/W in Alabama (its table was last updated 23 October 2026). Those figures come from EnergySage Marketplace data, so compare your own price per watt against your state, not a national number. For installed-cost research, see the National Laboratory of the Rockies’ installed system cost page.
Value-based pricing sets the price against the customer’s savings and the local market rate rather than your cost. It lets you capture more of the gap between what the customer pays the utility and what your system costs. It fits an exclusive conversation, such as a referral, a canvassed first touch or a repeat customer.
The Contrarian Take: Cost-Plus Wins Competitive Marketplace Leads
Match the pricing method to the lead, not to a philosophy. When a homeowner holds three quotes and plans to sign this week, a value-based premium has to be explained before it is read, and the customer is comparing price per watt. In that situation, sharp cost-plus pricing with a lean margin, fast delivery and a transparent breakdown is the safer choice. Referral and exclusive leads leave room for value-based pricing.
Set a margin floor from your own books: the margin that pays for warranty work, service calls and a slow quarter. Below that floor, walk away.
Formatting and Presentation Best Practices
Content decides whether your quote can win; formatting decides whether it gets read.
Put a one-page summary first. The decision page shows the four numbers plus the roof layout image. Everything else sits behind it.
Brand every page. Logo, colors, license number and insurance mention on each page.
Use visuals for the three things customers cannot picture: the panel layout on their roof, monthly production across the year and the cumulative savings curve. Replace paragraphs of explanation with one chart each.
Write plainly. “Your system produces 11,200 kWh in year 1, covering 94% of your usage” reads better than “STC-rated DC output modeled at 11.2 MWh with a 0.94 offset ratio.” (These figures are an illustration of tone, not a benchmark.)
Split the document into a decision page and an audit page. Different readers want different depth:
| Page 1 (the decision page) | Appendix (the audit page) |
|---|---|
| Total price and price per watt | Full line-item cost breakdown |
| Monthly payment options | Equipment datasheets and model numbers |
| Year-1 production estimate | Assumptions: utility escalation, degradation |
| Savings estimate | Licenses, insurance and references |
| Next step and expiry date | Contract and warranty terms |
Hold every rep to the same structure. Consistency across reps is what lets you compare results and coach the outliers.
Prefer interactive delivery over static files when your tooling supports it. Open tracking and e-signature let you see when the customer opened the quote and follow up while it is on their screen. Use the customer’s actual roof imagery, not stock photos, and name files like a professional: Smith-Residence-Solar-Quote-2026-10.pdf beats quote_final_v3.pdf.
Three formatting mistakes spoil otherwise good quotes: inconsistent fonts and spacing, equipment images copied from different manufacturers’ sites, and a document so long that the decision page gets lost. A template fixes all three.
Financing Options: How to Present Cash, Loan, Lease, and PPA
The IRS page above is the starting point: for cash and loan buyers of systems placed in service after December 31, 2025, there is no Residential Clean Energy Credit to net out, so the gross price faces the customer directly. Lease and PPA providers fall under separate rules from the homeowner credit. Ask the provider or your tax advisor, and quote only what they confirm in writing.
Present three or four options side by side in every quote. A single-option quote invites a single comparison, which is price. A comparison table invites a conversation about fit:
| Cash | Loan | Lease | PPA | |
|---|---|---|---|---|
| Who owns the system | Homeowner | Homeowner | Third party | Third party |
| Monthly payment | None | Fixed loan payment | Fixed lease payment | Per-kWh rate |
| Maintenance responsibility | Homeowner | Homeowner | Per the contract | Per the contract |
| Fits best when | The customer wants ownership and has the cash | The customer wants ownership without upfront cash | The customer wants a fixed payment without owning | The customer wants to pay only for production |
Two practices separate trustworthy financing pages from the kind that generate complaints.
Disclose the dealer fee on loans. The Consumer Financial Protection Bureau’s August 2024 report on solar financing says some lenders include markups and fees that can increase the loan principal by 30 percent or more above the cash price. It says these fees, often called dealer fees, are frequently baked into the principal, and it gives an example: a $30,000 cash price plus a $9,000 hidden fee (30 percent of the cash price) gives a $39,000 loan principal. Check: 9,000 / 30,000 = 30%, and 30,000 + 9,000 = 39,000. Show any fee on its own line so the customer can compare the loan against cash on equal terms.
State the assumptions behind every savings projection. A multi-year savings figure depends on a utility rate escalation assumption. For lease and PPA offers, show the escalator in the contract and what it does to the payment over the term. A fixed payment and a payment that rises each year are different offers, so put both in the table.
Also answer what happens when the customer sells the home. Cash and loan systems usually transfer with the house. For a lease or PPA, the contract sets whether the buyer assumes the agreement or the seller buys it out. Put the transfer path in the quote, because the customer’s real estate agent will ask. If you want word-for-word language for the loan, lease and PPA conversation, see these financing pitch scripts.
Follow-Up: The Quoting Process That Closes Deals
A good quote still loses if it arrives late or sits untouched after delivery. Speed signals how you will run the install, the service call and the warranty claim, so send the quote promptly after the site visit.
Delivery is a conversation, not an email attachment. Send the quote, then walk the customer through it live or on a short screen share the same day, and answer objections before they harden into silence.
After delivery, follow a fixed cadence instead of relying on rep intuition. Ask the customer’s preferred channel during the first call. This schedule is a suggested template, not a measured benchmark:
| Day | Touch | Channel | Goal |
|---|---|---|---|
| 0 | Deliver the quote and walk it through live | Call or screen share | Explain, do not just send |
| 1 | Confirm receipt and invite questions | Text or email | Surface objections early |
| 3 | Value touch: production report or reference customer | Add proof, not pressure | |
| 7 | Address the top objection directly | Call | Move to a decision |
| 14 | Quote expiry reminder, if your quote validity is 14 days | Urgency with a real deadline |
Track document opens if your tooling allows it. A customer who opens the quote several times in a day is telling you when to call.
Track your own close rate by lead source: referrals, inbound search, canvassing, marketplace and purchased leads. Close rates differ by source and market, so your own numbers are the right benchmark for your reps.
When the objection is price, resist the reflex to defend or discount. Ask what the customer is comparing against, walk your quote line by line, and ask which item they would remove to reach their target number. That turns a negotiation into a scope decision. The solar sales objection handling guide covers the other recurring objections.
Know when to walk away. A deal signed below your margin floor costs more than it earns once warranty visits and service calls land.
Common Quoting Mistakes That Kill Margin
Margins rarely die in one negotiation. They bleed out through quoting habits that feel harmless. Here are seven, with the fix for each.
1. Discounting before re-scoping. When a customer pushes on price, dropping the equipment tier or system size protects margin better than shaving the number. A re-scope shows that price follows the product.
2. Ignoring soft costs in the base price. Sales commissions, permitting and office overhead belong inside the cost base, as the pricing table above shows. The solar installation cost breakdown walks through where the money goes on a real job.
3. Overpromising production. An aggressive estimate wins the signature and returns later as a warranty dispute. Model shade honestly and show degradation assumptions.
4. Quoting a single option. One option invites one comparison: your price against the competitor’s. Several financing options shift the conversation to fit.
5. Slow turnaround. Every day between the site visit and the quote gives a faster competitor time to win the deal. If your process needs days, the process is the problem.
6. Vague equipment lines. “340W panels or equivalent” tells the customer you will install whatever is in the warehouse. Name exact models and honor them.
7. No change order policy. A change order clause that names the priced triggers, such as roof repair, main panel upgrade or trenching, prevents the most common disputes. Customers accept priced surprises more readily than unpriced ones.
A useful audit: pull your last 20 lost quotes and tag each with the mistake that most likely lost it. Count the tags. The most frequent one is where to start.
How Software Changes the Quoting Game
Manual quoting is a relay with several handoffs. The rep pulls the address into a design tool, exports a layout, rebuilds the numbers in a spreadsheet, then pastes everything into a PDF template. Every handoff is a chance for stale pricing or a copy-paste error.
Connected software puts those steps in one project file. SurgePV’s solar design software covers roof modeling, array layout, shading, energy yield and financial modeling, and generates the bill of materials and proposal from the same design. When the customer asks for a different panel, you edit the design once and regenerate, so the production estimate and the financials stay in step with the design.
A proposal template locked inside solar proposal software means every rep sends the same structure, the same assumptions and the same language about incentives. Managers can compare reps without normalizing for format. Results depend on source data, assumptions, equipment models and review, so check each output before it goes to a customer. SurgePV also offers Clara AI, an assistant inside the design workflow; ask for the tasks you care about in a demo. The sales professionals page describes how the workflow fits a sales team.
SurgePV publishes this guide and sells solar software. Pricing is on the pricing page: USD 1,899 per user per year for one seat, USD 1,499 per user for 3 seats and USD 1,299 per user for 5 seats, with access through a guided demo.

Conclusion
Quoting is the moment your sales process becomes a document the customer judges without you in the room. Three actions cover most of what matters:
- Price from your own costs, know your margin floor, and show price per watt.
- Include every element on the checklist, name the equipment, and add an expiry date and a clear next step.
- Present financing options side by side, show any loan fee, and follow up on a set schedule.
Start with the fixes that cost nothing: repair your template, name your equipment, add the expiry date and send the quote promptly after you measure the roof. Then look at tooling that makes quick turnaround routine. To see the workflow end to end, book a free demo and bring a real project.
Frequently Asked Questions
What should be included in a solar quote?
System size and layout, named equipment, a production estimate with its shading assumption, total price and price per watt, financing options, timeline, warranty terms, and a next step with an expiry date. If any element is missing, ask the installer to revise the quote before you compare it with others.
How do you price a solar system for profit?
Add up true project costs, including sales, permitting and overhead, then add a margin. Decide whether you mean margin on price or markup on cost: a $17,000 cost with a 20% margin on price gives a $21,250 quote, which is a 25% markup on cost.
What is the difference between margin and markup in a solar quote?
Margin is profit as a share of price; markup is profit as a share of cost. In the example above, $4,250 of profit is 20% of the $21,250 price and 25% of the $17,000 cost.
What is the best solar quote format?
A branded one-page summary with the roof layout and the key numbers, backed by an appendix with the line-item cost breakdown, datasheets and contract terms. Digital delivery with open tracking and e-signature lets you follow up while the customer is reading.
Is the 30% federal solar tax credit still available for homeowners?
The IRS says the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025. Do not net it out of a quote for a system placed in service in 2026.
What is a solar loan dealer fee?
A markup or fee that a lender builds into the loan principal. The Consumer Financial Protection Bureau’s August 2024 report says some of these fees can raise the principal by 30 percent or more above the cash price. Show the fee on its own line in the quote.
How do you respond when a customer says your quote is too high?
Ask what they are comparing it to. Walk your quote line by line, show the value of the equipment, warranty and service, and ask which item they would remove to reach their target price. If the gap is real and the scope cannot move, walking away costs less than winning the job below your margin floor.
