How to calculate solar array annual output
This calculator finds total annual solar array output by multiplying array size by the annual energy yield per kilowatt.
How the calculation works
Annual output = Array size × Annual yield per kW.
Example
An 8 kW array with an annual yield of 1,300 kWh/kW (a typical figure for many US locations, varying by climate and orientation): 8×1,300 = 10,400 kWh/year.

Pro Tips for Solar Array Annual Output
- Annual yield per kW varies significantly by geographic location, panel orientation, tilt angle, and shading — use a figure specific to your actual site conditions, often available from solar resource maps.
- Panel degradation reduces output slightly each year (commonly around 0.5% annually) — factor this into long-term production projections for financial planning.
Common Solar Array Annual Output Mistakes to Avoid
- Using a generic annual yield figure without adjusting for your specific location's solar resource, orientation, and shading, which can vary significantly between sites.
