Plan
Which way a fixed panel should face where you are, and at what angle. Worked out from your location in this browser, with the reasoning and the limits of it shown alongside.
Your browser asks you for a location, and Solink turns it into the direction and angle a fixed panel is usually set to there. The answer is worked out in this browser: no coordinates are sent to Solink or stored.
Your browser will ask first, and you can refuse.
Your browser's own location stays in this browser: Soltis never receives it, and it is shown rounded to about a kilometre. An address you type is different. It goes to Soltis' server to be resolved, and where it lands is saved to your Solar Profile so the rest of Soltis knows where the roof is.
