Solar Proposal Generator
A solar proposal generator does the work a designer, an estimator and a spreadsheet used to split between them: it reads the site address and the monthly electricity bill, sizes the array against local irradiance, lays the panels out on the roof, prices the bill of materials and prints a proposal the customer can sign.
SolvSolar runs that whole chain in about 45 seconds and keeps the regulatory layer current — PM Surya Ghar and DISCOM net-metering rules in India, federal incentive modelling and NEM 3.0 in the USA, and STC-aware pricing fields in Australia. 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. On-grid, off-grid and hybrid (with BESS sizing) are all first-class system types, so the financial page reprices itself when you change configuration.
Seats are free, so field sales, design and procurement can all work from the same generated proposal. Billing is metered per kW designed instead of per user.
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.
Which solar software works for rooftop EPC companies?
Rooftop EPC companies need per-project costing, a bill of materials that matches procurement, and unlimited seats for field sales. SolvSolar gives all three: array layouts for RCC, metal-sheet and ground-mount roofs, an editable BOM with specifications, and pricing metered per kW designed instead of per user.
Does SolvSolar design on-grid, hybrid and BESS systems?
Yes. Every proposal starts with a System Type choice of on-grid, off-grid or hybrid, and hybrid designs add battery energy storage (BESS) sizing with backup-hours and depth-of-discharge assumptions. The financial page then reprices the system, subsidy and payback for the selected configuration.
