Sunplan: Solar Forecast

Sunplan predicts how much energy your solar installation will produce — hour by hour, seven days ahead. This is not a weather app with a chart bolted on. Sunplan calculates output from a physical model: the sun's position for your exact coordinates, your roof geometry, and how forecast cloud cover attenuates solar radiation. HOW IT WORKS You enter your installation parameters: capacity, azimuth, tilt angle and location. Sunplan computes clear-sky irradiance, then corrects it for forecast cloud cover from Apple WeatherKit. The result is predicted production in kWh, for every hour and as a daily total. WHAT YOU GET - 3-day production forecast - Hourly breakdown with the daily production peak - Daily totals in kWh - Day-to-day comparison - Multiple installations, if you have more than one array WHO IT'S FOR For anyone running rooftop solar who wants to plan self-consumption.
