Calculate the optimal solar panel tilt angle for your location. Get monthly, seasonal and yearly angles for any address worldwide. Works for both hemispheres. Free.

How does it handle locations with extreme latitudes where the sun barely changes angle through the seasons, like near the Arctic Circle?
Finally a tool that just gives you the tilt angle without trying to upsell you on installation services. Works great for my address, gave me monthly adjustments I never thought to ask for.
Plugged in my address and the yearly angle came out a degree off from what I'd been using on my panels. Quietly impressed.
