Select an engine to run instant calculations using local climate data and current utility rate structures.
Panel count sizing
Battery capacity math
Net-metering estimates
Calculate exact kilowatt-hour production sizing based on regional solar irradiance averages and roof orientation.
Determine necessary kWh reserve capacities paired with essential load backup schedules for uninterrupted power.
Project long-term payback periods accounting for annual utility rate increases, federal tax credits, and degradation.
The math behind our solar projections
Our calculation engine relies on publicly audited meteorological data sets and standardized photovoltaic performance ratios. We factor in temperature coefficients, inverter clipping losses, and regional shading factors to deliver unbiased estimates.
Every assumption is fully documented and adjustable. Modify panel efficiency ratings, local utility buyback tariffs, and financing terms in real time to inspect the exact mathematical impact on your projected return on investment.
