Solar Business Software: What Each Tool Does for an Installer, and the Gap None of Them Fill

Updated October 27, 2026

By Moni Mindich, founder, 20 years in home improvement

Solar business software is not one product. An installer runs a design and proposal tool, a CRM that tracks each project from signed contract through permit, install, inspection and permission to operate, something for crews and service calls, accounting, and a phone that has to be answered while everyone is on a roof. This guide sorts the tools by the job they do and shows where most installers still lose deals.

Quick answer: Most solar installers need four kinds of software: a design and proposal tool (for example Aurora Solar, Solargraf or the free OpenSolar), a CRM and project tracker that follows each job through permitting, interconnection and permission to operate, a field service or O&M tool for crews and service calls, and accounting. The gap none of them fill is answering and booking new inquiries the moment they call.

Solar software, sorted by the job it does

Search results for solar business software mix design platforms, CRMs and full ERPs, and most of the roundups are written by vendors ranking their own product first. It is easier to choose when you sort by job.

What to buy at each size

Worked example: what slow lead response costs an installer

Solar inquiries are expensive to generate and easy to lose: a homeowner who fills in three quote forms books with whoever calls back first. The rates below are assumptions except where cited. Home-service businesses answer 52% of calls with a person, 38% of answered calls are leads and 45% of those leads convert on the call (Invoca, July 2026, all home services, not solar only).

On these assumptions the gap is about 1.4 systems and $34,200 in monthly revenue, from the same marketing spend. None of the design or CRM tools above close it; they start working after someone has booked the survey. Try your own numbers in the solar quote calculator.

Questions to ask before you sign

Where Unmanually helps

Unmanually is a 24/7 AI Office Manager for solar installers that you run by voice. The AI Office Manager answers new inquiries while your crew is on a roof, asks your qualifying questions (homeowner, roof age, shade, average electric bill), books the site survey and sends the confirmation. It also answers "where is my install?" calls from what you have told it, sends invoices and chases deposits. See Unmanually for solar installers, and how to get solar leads without door knocking.

FAQ

Common questions

What software do solar installers use?

Usually a design and proposal tool, a CRM or project tracker with permitting and interconnection stages, a field service or monitoring tool for crews and service calls, and accounting software.

Is there free solar design software?

Yes. OpenSolar describes its software as 100% free of charge on its website (checked October 27, 2026). Paid tools such as Aurora Solar and Solargraf add features; test the proposal your customers will see before choosing.

What is the best CRM for a solar company?

The one that holds your real project stages: site survey, permit, install, inspection, interconnection and permission to operate, with dates and documents. Solar-specific CRMs have these built in; a general CRM can work if you set the stages up.

Does solar software answer customer calls?

No. Design, CRM and field tools work after a survey is booked. Answering and booking new inquiries needs a person, a call service, or an AI Office Manager such as Unmanually.

Turn the hours this takes into minutes of talking.

Home service businesses answer only about half their calls (Invoca, July 2026), and owners spend about 11 to 16 hours/week on admin. Knowing what to do is the easy part; the money leaks out in the calls you can't take, the quotes nobody chases and the invoices that sit unpaid. Unmanually is a 24/7 AI Office Manager for solar installers that you run by voice from your phone:

  • Answers your business line 24/7, quotes from your price list and books the consultation on the live call, so the customer doesn't ring the next company on Google.
  • Sends the quote, follows up until they say yes, then sends the invoice and chases it until it's paid.
  • Texts confirmations and reminders, keeps your calendar and remembers every price and promise.
  • Plus a free website for your business, set up for you. On a plan, every form fill gets a call back from your AI Office Manager in about a minute.
