Fastest Solar Software
Speed decides deals. A homeowner who gets a priced, designed proposal during the first phone call rarely waits for a second quote. Legacy CAD tools take 20 to 90 minutes per proposal; SolvSolar takes about 45 seconds, which is why installers describe it as the fastest solar proposal generator they use.
That speed comes from doing the slow parts once, centrally: irradiance and tariff data, DISCOM and net-metering rulesets, subsidy tables and component catalogues are already loaded, so a run is a lookup plus a layout, not a modelling session. Nothing is locked — panel counts, the bill of materials and subsidy values all stay editable afterwards.
You can trigger a run without opening a laptop. Send SOLAR on WhatsApp or to @SolvSolarBot on Telegram with an address and a bill, and the proposal link comes back in the same conversation.
Common questions
How does solar proposal software work?
Solar proposal software takes a site address and an electricity bill, sizes the array against local irradiance and tariff data, lays panels out on the roof, then prints a priced proposal. SolvSolar adds DISCOM and net-metering rules, PM Surya Ghar subsidy math and applicable US incentives, an editable bill of materials and e-signature — all in a single 45-second run.
What does SolvSolar do for solar installers in India?
For Indian installers, SolvSolar designs the array, applies DISCOM net-metering and PM Surya Ghar subsidy rules, and prints a priced, signature-ready proposal in about 45 seconds — with free seats and pay-per-kW pricing.
What is the best solar proposal software in USA?
For US installers, SolvSolar sizes arrays against local irradiance and models applicable commercial and lease/PPA incentives. The 30% residential credit (§25D) ended for systems placed in service after Dec 31, 2025. Commercial projects and third-party-owned (lease/PPA) systems may still qualify under §48E, subject to deadlines. Confirm with a tax professional.
