A 5kW solar array can generate about 20kWh in good weather, but requires plenty of sunlight and mild weather. Still, this amount of energy is enough to power her average home of four. It is important to remember that the maximum output of a solar system is based on available sunlight. So, before purchasing, you should determine how much power your home needs.
A 5kW solar system can cost over $20,000, but can save thousands of dollars in the long run. To save as much money as possible, reduce your energy consumption first before you start your installation. To do this, replace your light bulbs with LEDs, insulate your home better, and seal air leaks around your doors.
An average US home uses 10,800 kWh of electricity per year, so a 5 kW solar array can provide enough power for 40-80% of a home’s energy needs. However, this number is based on the amount of electricity you use and the amount of solar energy available in your area. As a rough estimate, a 5 kW system requires 19,265 watts of solar panels.
