To obtain the average amount of energy used by a house in the United States, 2,000 square meters. The home would need between 16 and 21 solar panels. That's assuming the house has a good south-facing roof that gets all the sunlight every day. Depending on the location, an average 2,000-square-foot home will need between 16 and 25 solar panels to meet all of its electricity demand.
You can work with a solar energy professional to determine how many watts you need each panel to produce, and they can help you find options. If that house has a south-facing roof with no shade during the day, it would need between 14 and 22 premium solar panels to generate that amount of electricity. Solar installations are a one-of-a-kind product, and the average costs of solar panels vary greatly depending on your location and the manufacturer of the solar panels chosen. The most accurate way to find out is to hire a professional solar installer to perform an analysis of your home.
To get the most realistic estimate of the cost of your solar energy system, you should consider factors other than the purchase price of the panel. Depending on where you live, an average 2,000-square-foot home will need between 14 and 22 premium solar panels to meet 100% of your electricity needs. In this case, “premium” refers to solar panels with a rated power of 400 watts or more, which are the most efficient panels currently available. Assuming that a single panel generates 45 kWh per month and the average American household uses about 900 kWh per month, you'll need approximately a minimum of 20 solar panels to cover all your electricity needs.
That average 2,000-square-foot home that uses 967 kWh per month would need between 21 and 33 affordable solar panels to meet all its electricity needs. Homeowners who are interested in using solar energy often want to know how many solar panels will be needed to power their home. On the other hand, many solar contractors estimate solar energy costs based on the number of watts needed to meet your home's energy requirements. You can run the air conditioner with solar energy, but for constant cooling, you'll need to have solar batteries installed or switch to the power grid during the night, since solar panels only provide power while receiving sunlight.
