Solar sales, without the spreadsheets.

Inverta gives every solar installer a branded calculator, an automatic lead inbox, and professional proposal PDFs — so quoting a customer takes minutes, not days.

How it works for installers

1

Set up your calculator

Sign up, add your products and prices (or start with our template), and get a branded calculator link in minutes.

2

Share one link

WhatsApp status, Instagram bio, flyers — customers size their own system and every submission lands in your lead inbox.

3

Send proposals that close

Turn any lead into a professional PDF proposal — load analysis, cost breakdown, and your payment details — in two clicks.

And for homes & businesses

Know what you need — free

Pick your appliances, tell us your backup needs, and get an instant system sizing: inverter, batteries, and panels — with real prices from a local installer.

Work with trusted installers

Every calculator on Inverta belongs to a real installer who follows up with a formal quote — browse them by state and pick who you work with.
