Comparison

Solset AI vs OpenSolar

OpenSolar is free for installers because manufacturers, lenders and distributors pay to be on it. It covers design, proposals, payments and finance, and it does that at no cost.

reasons to pick OpenSolar instead

Solset AI is built for the company that also has to buy the materials, schedule the crew, file the grid connection, invoice in its own country’s tax and service the plant. That depth is what you pay for.

OpenSolar in one line: Free software to design, sell and manage solar projects, paid for by partners rather than installers.

Credit where due

Where OpenSolar is genuinely strong.

  • Free to use, according to its own site.
  • A wide span: auto design, auto BOM, SLDs, proposals, e-signature, milestone payments, integrated finance and a supplier shop.
  • Self-serve signup and use across many countries, per its site.
Pricing

How the two are priced

OpenSolar: OpenSolar’s home page says the software is free of charge. Paid add-ons (enterprise services, imagery, API) are listed without prices; its pricing pages did not load when we checked.

Solset AI: priced per workspace, not per user. A plan covers the company, extra seats are an add-on, and the Free plan needs no card and does not expire. Every current figure is on the plans page, read from the live catalogue.

OpenSolar’s details are from its own website, read on 3 November 2026. Check their site before relying on them.

Be honest about it

When to pick OpenSolar instead.

  • Cost is the deciding factor and free matters more than depth after the sale
  • You want partner finance offers in your proposals in a market where those partners operate
  • Your installation and accounts already run in another system
