Win solar customers by being the installer homeowners can check and believe. Pitch real numbers, since the federal homeowner tax credit ended for systems installed after 2025. Build cancellation rights into every contract signed in a home, and get consent before marketing calls or texts. Then build steady sources of work: referrals from installed systems, roofers and electricians who see worn roofs and full panels first, plain guides to each utility's export rules, and patient follow-up on every open proposal.
If you sell in homes, after a knock on the door or a phone call, you're working in the setting FTC consumer advice warns homeowners about: contractors who show up at the door or call, push for a decision on the spot, or ask for cash or full payment up front 1 2. The same advice tells homeowners to check a contractor's license and insurance, compare written estimates and sign a written contract before work starts 1. Make every one of those checks easy:
If any of your marketing still promises homeowners the 30% federal tax credit, it's out of date. The Residential Clean Energy Credit (section 25D) equaled 30% of the cost of qualified clean energy property installed from 2022 through 2025, and no credit is allowed for expenditures made after December 31, 2025 4. The IRS treats an expenditure as made when installation is complete, so a system finished in 2026 doesn't qualify even if the customer signed or paid in 2025 5. Battery storage was on the same list of qualifying property, so the cutoff applies to batteries too 4.
Check everything a prospect might see for credit language about homeowner-owned systems: web pages, ads, social posts, door hangers, mailers, door-knocking and phone scripts, referral emails, and proposal and financing templates, especially any "net cost after tax credit" line.
Then retire the urgency that came with the credit. "Sign before the credit expires" no longer has a deadline behind it, and inventing a new one is worse. Give real reasons to decide, such as open dates on your install calendar or a utility rule change that has actually been announced.
The claims that replace the credit need the same care:
Door knocking can fill a calendar with bill reviews. Run it so no homeowner could mistake your team for the people the FTC warns them about.
When a contract is signed in the customer's home, plan on the FTC Cooling-Off Rule applying. It covers sales of $25 or more at the buyer's home and $130 or more at temporary locations such as a convention center, fairground or hotel room, which matters if you sign contracts at home shows 9. The buyer can cancel for a full refund until midnight of the third business day after the sale. Saturday counts as a business day; Sundays and federal holidays don't 9.
An invited visit can count too. The rule's definition of a door-to-door sale includes sales made "in response to or following an invitation by the buyer," when the buyer agrees to buy somewhere other than your place of business 10. A homeowner who booked a consultation on your website and signed at the kitchen table can still be covered.
Solar paperwork moves fast after a signature, so sequence it around the window:
Example: A homeowner signs at their kitchen table on a Friday evening. Saturday is business day one, Sunday doesn't count, Monday is day two and Tuesday is day three, so they can cancel until midnight Tuesday, as long as no federal holiday falls in between. File the permit and interconnection applications on Wednesday. If you file on Saturday and they cancel on Monday, the plan set, the fees and the design hours are a loss you can't bill to anyone.
Marketing calls and texts are regulated, and much of the risk turns on consent. How to follow up on quotes covers the federal consent and Do Not Call rules; check your state's rules too. In a solar business the risk points are predictable:
A finished solar job keeps working for you. The array is often visible from the street, and the owner can show a neighbor what it produces and, after a few billing cycles, what their bills look like now. Ask while that proof is fresh:
Set the program rules in writing:
Example: Say you spend $4,000 a month on bought leads and they turn into 2 installed systems: $2,000 of lead cost per install, before anyone's sales time. A referral program that pays $500 per installed system costs $500 per install and nothing for referrals that never sign. Even at one referred install a month, that's the cheaper job to win. All numbers are made up; run the comparison with your own costs and install counts.
Other trades meet your future customers first, at the moment the house is changing.
| Partner | What they see first | What you can send back |
|---|---|---|
| Roofers | New roofs, a natural time to add solar, and worn roofs that should be replaced before an array goes on | Customers whose roofs need work before an install |
| Electricians | Full panels, service upgrades, EV chargers and generators | Panel and service work on your jobs, where you aren't licensed for it yourself |
| HVAC contractors | Heat pump installs and other changes that raise a home's electricity use | Customers asking whether a new heat pump changes their system size |
The roofer relationship protects the customer as much as your pipeline. An array stays on the roof for many years, and if the roof wears out first, the array has to come off and go back on for the reroof, a job the homeowner pays for. Before you trade referrals with a roofer, agree on:
With electricians, settle who designs the interconnection, who pulls which permit, who meets the inspector and how a panel upgrade shows up on the customer's price. Put any referral fee in writing so both sides know when it's owed.
The questions homeowners ask about solar are local: how their utility credits the power they send to the grid, what they'll still pay each month and how long approval takes. Net metering and other export credit rules vary by state and utility, and they change. Answer those questions on your website, with one page for each utility you serve. You answer them at every kitchen table anyway, and a clear page earns trust before the first call.
Each utility page should cover:
Link each rule to the utility's tariff or the state commission's decision, add a "last checked" date, and check again before you quote. Describe today's rules without predicting future rates, and update the page as soon as a change is announced. Then send the page after every bill review in that territory, so the customer can reread it with whoever else is deciding.
Solar proposals stall for reasons that have nothing to do with your price. Write down what each one is waiting on:
Follow the event, not a timer. Ask when the HOA meets and check in the day after; call when the financing decision should be back. When an input really changes, such as a new rate schedule or an equipment substitution, update the proposal, resend it and say what changed. If the answer is no, ask why and log the reason (price, roof, financing, timing or another installer), because those reasons show you what to fix.
The general cadence, and what to say at each touch, is in the quote follow-up guide linked above. Keep the list of open proposals where you'll actually check it, whether that's a spreadsheet or field service software. Redline, which is chat-first field service software, includes quote follow-up for this.
Between a solar signature and a finished job sit the cancellation window, financing, the site survey, the permit and interconnection. A channel that signs plenty of contracts that never get built can look better than it is. Record the source of every lead (door knocking, referral, trade partner, bought leads, home show, website) and measure each one by installed systems: the share of its leads that become installs, and its customer acquisition cost per install.
Example: Over one quarter, door knocking costs $12,000 in canvasser pay and materials and produces 20 signed contracts, 14 of which are installed. Referrals cost $4,000 (seven $500 rewards plus $500 of printed cards) and produce 8 signed contracts, 7 of which are installed. Door knocking costs $600 per signed contract but about $857 per installed system. Referrals cost $500 per signed contract and about $571 per installed system. Made-up numbers, for illustration only.
Door knocking can still be worth it when you need volume. The numbers tell you what that volume really costs, and customer acquisition is a cost every price has to carry, as the solar pricing guide linked above explains.
It depends on where you sell. Your state may require people who sell home improvement contracts to register or to work under your contractor license, and towns can require their own solicitor permits. Check with your state's contractor licensing board and with each town clerk before your team goes out, and have every rep carry copies of the permits that apply.
Yes, with care. Get the customer's written permission, use their actual bills, and don't imply that every customer will see the same result. Savings depend on the home's usage, the roof and the utility's rates, so say so next to the example. If that customer earns referral rewards or anything else from you, say so where the testimonial appears. When in doubt, have a lawyer review the ad before it runs.
Treat bought leads as one more channel and judge them the same way: cost per installed system and sales hours per install. Before you buy, ask the seller in writing whether each lead is exclusive or also sold to other installers, and how each person's consent to be contacted was collected. Run a full quarter and compare the results with referrals and trade partners before you commit to more.
Rules and figures change, and many requirements vary by state and city. Check the current version of each source and your local authority before acting, and talk to a licensed professional about your specific situation.
