About Rayern
We help homeowners make clean energy decisions they feel good about
Rayern started with a simple frustration: getting a solar quote shouldn't mean dozens of sales calls and numbers you can't check.
Our mission
Make clean energy simple, transparent and fair
Solar panels, batteries and heat pumps are some of the biggest purchases a household makes. Yet the process is often confusing, with estimates built on hidden assumptions and contact details sold to the highest bidder.
Rayern brings it all into one place: tools that show their math, guides written to inform rather than sell, and a marketplace where you stay in control. We're free for homeowners and always will be.
What we stand for
Our principles
Honesty over hype
We show the assumptions behind every number, including when solar isn't a good fit.
Your data, your call
We never sell your contact details. You choose which installers see your project.
Quality installers only
Every company is checked for licensing, insurance, track record and warranty before joining.
Cleaner homes for everyone
From rooftop solar to community solar, we help every household find a way to participate.
