Solar Load Planner

Solar Load Planner is a home solar system and backup power calculator. Add your electrical devices, power ratings, and operating hours to estimate consumption, solar panels, batteries, inverter size, backup time, and system payback before buying equipment.

With Solar Load Planner you can:

• create separate projects for homes and usage scenarios;
• estimate current load and daily energy consumption;
• mark devices that must remain powered during an outage;
• select solar panels, batteries, and an inverter;
• review power headroom and approximate backup time;
• estimate system cost, savings, and payback;
• use a compass for basic panel direction guidance;
• save and duplicate calculations on your device.

Solar Load Planner is designed for homeowners, backup-power users, consultants, and installers during early planning.

All results are estimates. Actual solar production and backup time depend on the season, weather, shading, panel angle, equipment losses, battery condition, and real usage. Solar Load Planner is not a replacement for a professional electrical design.
