Understanding Your Results

Daily Power Usage

This is your total daily power consumption in watt-hours (Wh). It's calculated by multiplying each appliance's wattage by the hours of daily usage.

Recommended Solar

This is the minimum solar panel capacity we recommend for your needs, adjusted based on your location's solar irradiance. We add a 30% buffer to account for efficiency losses and less-than-perfect sun conditions.

Battery Capacity

The recommended battery capacity to store energy for your needs. We size batteries to handle your daily needs while never dropping below 50% capacity (which extends battery life).

Savings Estimate

This shows your potential annual savings by using solar power instead of a generator, based on current fuel prices and your region's electricity costs.
