SolVisIQ vs Sunplan

SolVisIQ is an intelligent companion app for solar photovoltaic (PV) installations. Whether you own a rooftop solar system or manage a single site, SolVisIQ gives you complete visibility into your energy production and consumption. REAL-TIME MONITORING • Live production data from your inverter • Energy consumption and grid import/export tracking • Historical charts by day, week, month, and year • Interactive calendar view of daily production SMART INSIGHTS • Automatic self-consumption and self-sufficiency calculations • Energy cost analysis using real-time electricity prices (ENTSO-E) • Sensor-based orientation assistant for optimal panel positioning • Production trends and performance overview INVERTER SUPPORT • Solis inverters (via official cloud API) • Sungrow inverters (via official cloud API) • More brands coming soon REPORTS & EXPORT • Generate detailed PDF reports • Export raw data as CSV • Share reports directly from the app via any platform NOTIFICATIONS • Configurable local alerts • Daily production summaries AVAILABLE IN 26 LANGUAGES SolVisIQ is fully localized in 26 languages, making it the ideal companion for solar owners worldwide.

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. Know in advance which day is worth running the dishwasher, the washing machine or the EV charger — and when to charge your home battery from the grid instead. PRIVACY Sunplan has no server. Every calculation runs on your iPhone. No account, no email, no sign-in. Your installation parameters stay on the device. I collect nothing. No ads, no tracking. ABOUT ACCURACY A production forecast is only as good as the cloud forecast behind it. Next-day predictions are usually close. The further out the day, the wider the uncertainty — especially under broken cloud, when output swings minute to minute. Sunplan shows a prediction, not a promise. Treat it as a planning tool. WHAT SUNPLAN DOESN'T DO It doesn't connect to your inverter or read actual production. It doesn't control anything in your home. Nothing to install beyond the app. I built Sunplan because I run solar at home and wanted to know what to expect. I'm still developing it — if something's missing, write to me.
