Most solar panels on the market today are between 250 and 400 watts. A 4 kilowatt (KW ) system would require between 10 and 16 solar panels to produce that much power. The average home in the United States uses about 940 kilowatts of power per month, so a 4 KW system produces about 4% of the power an average home uses in a month.
The exact number of solar panels that you need to make up a 4 kW solar system will depend on the Power rating (Wattage) of the solar panels you plan on using. For example, if you use 200 Watt solar panels, you’ll need 20 solar panels to make up 4000 Watts (4000W ÷ 200W = 20).
Assuming you have 4.5 kilowatts (KW ) of solar panels installed on your roof, in one day they can produce around 16 kilowatt-hours ( kWh). That’s enough to power four 100-watt light bulbs for 10 hours each or a 1,200-watt appliance for two hours. In other words, the average home uses about 30 kWh per day.
A 4kW solar panel system can run the average three-bedroom household, on a typical day. It can usually generate around 9.3kWh of solar electricity per day in the UK. This amount of electricity can power all of the following devices for the stated amount of time, according to Centre for Sustainable Energy data – and still have 1kWh left over.
The number of solar panels in a 4kW system depends on the size of the panels themselves. If you have a 400W panel, it will produce 400 watt-hours in standard test conditions, which includes a cell temperature of 25°C and solar irradiance of 1,000W per m², and is how every company checks a solar panel’s capabilities.
You should usually add a 5-6kWh battery to a 4kW solar panel system. This will allow you to store your excess solar energy all year round, to use on cloudy days and after the sun goes down.
