Best AI tools for solar installers (2026)

Updated Oct 17, 2026 · Prices as of Oct 2026 · Some links may be affiliate links (disclosure)

Residential solar is a long sale with a lot of paperwork behind it. A homeowner sees an ad, fills out a form, wants a number, wants to see panels on their roof, worries about the utility bill, asks about incentives, and then you're into permits, utility interconnection, inspections and a commissioning visit. Small installers who win against the big national sales companies usually do it with faster, more honest proposals and better follow-through.

Design and proposal software

If you're a small or new installer, start with OpenSolar. Free is hard to argue with, and its proposals are good enough to sell against bigger companies. Move to Aurora if you need its finer modeling, run many designs per rep, or your financing partners and lenders expect it.

Around the design tool

Lead to signed contract

1. Respond in minutes, not hours. Solar leads usually go to several companies at once. A quick text asking for a recent electric bill photo and the best time for a call keeps you in the running.
2. Remote design first. With the address and a year of usage, you can design a system on satellite imagery before anyone climbs a roof. Send a preliminary proposal the same day.
3. Site survey to confirm. Roof condition, rafter size and spacing, main panel capacity, shading the imagery missed. Book it with a scheduling link.
4. Final proposal with honest assumptions. Show the utility rate you used, the rate escalation assumption, and incentives you're confident apply. Customers who've been burned by aggressive sales reps notice honesty.
5. Follow-up. Many people need time to decide. Set reminders at day 3, day 10 and day 30.

Heads up: the federal solar credit is gone

The 30% federal residential clean energy credit (Section 25D) ended for expenditures made after December 31, 2025, under the 2025 tax law, according to the IRS. Plenty of homeowners still think it exists, and some older proposal templates still show it. Strip it out of 2026 proposals and lead with what's real: state and utility incentives where they exist, net metering terms, and plain bill savings. Check your design tool's incentive settings too.

Where AI genuinely helps a solar installer

• Explaining the bill. "Explain net metering to a homeowner in plain English for [utility], using these rules: [paste the utility's rules]." Give it the real rules; don't let it guess.
• Permit and interconnection narratives. AI can turn your design details into the written portions of permit packets and keep a checklist per jurisdiction. Drawings and electrical details still come from your design tool and your licensed people.
• Objection replies. "My neighbor said solar ruined his roof." "What if I move?" Write calm, honest answers once and reuse them.
• Post-install care. Monitoring app setup instructions, what to do when production drops, when to call. Fewer "is it working?" calls.

Canned replies

• New lead: "Thanks for your interest in solar! Could you text a photo of a recent electric bill (both pages)? With that and your address we can design a system and send numbers today."
• Preliminary design: "Here's a first design based on satellite imagery and your usage. We'll confirm everything at a site survey; no commitment until then."
• Permit and utility: "Your permit is submitted and we've applied to the utility for interconnection. This part usually takes [X] weeks. We'll update you every Friday until it's approved."
• Install reminder: "Install day is Tuesday. We'll need access to the attic and main electrical panel. Power will be off for a short time in the afternoon."
• Permission to operate: "Good news: the utility approved your system. Here's how to turn it on and set up the monitoring app."

The weekly update during permitting is the one most installers skip, and it's the one customers remember. Long silences are when they start calling the sales rep who already got paid.

The real monthly number

Where it breaks down

Production estimates are estimates. Shade from a neighbor's tree that grows, a dirty array or an inverter fault will change real-world output; say so. Incentives and net-metering rules change, sometimes mid-sale. Date your proposals and recheck before signing. Free software means you trade money for some limits on support and integrations. Fine for most small installers. AI is not a source for tax-credit or rebate amounts. Point customers to their tax professional and the program's own pages.
