An 8kw solar system can generate 32 and 40 kWh of electricity per day, 11,680 and 14,600 kWh per year, and requires 20 400w solar panels, which cost $11,680 and $16,800 after tax credits. The expected 8kW solar system daily output would be close to 1,000 kWh per month or about 33 kWh daily. This is enough to run a refrigerator, microwave, lights, fans, TV, laptop, washing machine, small well pump and a window air. . The 8kW rating is determined under Standard Test Conditions (STC), which involves a panel temperature of 25°C and an irradiance of 1,000 watts per square meter. These perfect conditions are rarely sustained in the field, meaning the system is unlikely to operate at its full 8kW potential for. .
