Solar power and storage

1. PV string sizing and energy yield with hourly weather data

   Size PV strings against the inverter limits at the coldest and hottest site temperatures, then simulate the energy hour by hour from NASA POWER, PVGIS or EPW weather data, with monthly results, a loss chain, variants side by side and a design report.

2. Battery storage sizing: self-consumption, peak shaving and off-grid

   Size a battery from a year of consumption and PV production: self-sufficiency, self-consumption, cycles and savings for each capacity, the energy and power needed to cap the grid peak, and an off-grid check, from monthly totals or a 15-minute meter file.
