Aurora Solar and OpenSolar are best known as design and proposal tools, while RAYVO is a whole platform: 3D design plus CRM, ERP, stock and finance on one record. If design is all you need, compare the design depth; if you want to run the business in one place, compare the whole flow. Confirm every vendor's current features and prices with them.
Aurora Solar
Aurora is a design and sales tool used widely in the United States, known for polished proposals. Aurora does not publish its prices on its website; third-party reviews in 2026 report per-user plans on annual billing. Its tax and incentive handling is built around its main markets.
OpenSolar
OpenSolar offers its core design and proposal platform free, with paid add-ons. It is a design and proposal tool rather than an ERP.
RAYVO
- 3D design of any roof outline, shading by month for every module, IS 875 wind, strings, bill of materials and proposal.
- CRM, quotations, projects, stock, serial numbers, invoices, payments and payroll on the same record.
- India's GST, e-invoice, subsidy and net-metering rules built in; for other countries, tell us how tax and utilities work there.
- Published yearly and monthly prices.
How to decide
If you only design and hand over, test the design tools on your hardest roof. If you want the lead, the design, the quotation, the material and the invoice in one place, test RAYVO with one real customer from first call to payment.
