Solar Watts Needed For House

solar watts needed for house

A home that is powered by solar energy is not a dream come true, but the number of solar watts needed can be overwhelming. This article will outline factors to consider when deciding the size of a system, how many peak sunlight hours your home gets each day, and how much it will cost. Using this information, you will be able to make the right decision for your home. But before you make your decision, you should understand how much power your home uses.

Power consumption

Before choosing a solar panel, determine how much electricity you use every day. You can do this by looking at previous electricity bills, or by looking at reports generated by a whole-house monitoring system. These systems connect to the house’s main breaker panels and record data that is sent to your computer or phone. Then, round up the number to the nearest whole number. Once you’ve determined the amount of power you need to offset your electricity bills, you can begin your solar panel selection.

Peak sunlight hours

Depending on the latitude, the average number of peak sunlight hours varies from two to seven in different parts of the U.S. In general, the closer to the equator you are, the higher the number of peak sun hours you’ll need for your house. In order to find the optimal amount of solar energy for your house, you can consult a chart of peak sun hours in your area.

Size of system

The size of solar system needed for a house varies, but there are some common factors to consider. The amount of energy used in a household is a significant factor, and the U.S. Energy Information Administration gives an idea of the average use of electricity by households. A look at your own utility bill can also provide a good indication of the amount of power your home consumes. Then, based on that amount, you should determine the size of solar power system that would be best for your house.


The cost of solar panels can be a significant factor when considering converting to renewable energy. But how do you determine the cost of solar panels for your home? The best way to estimate the cost of solar panels is to calculate your house’s energy consumption and determine the appropriate size of your solar panel system. You can use tools like solar panel calculators and find out how much solar power your house would require. And, don’t forget that solar panels come with a range of additional benefits, such as solar water heating, a solar swimming pool, or heating your water.

Tax credits

If you are considering installing a solar power system on your home, you may qualify for a tax credit. You can take up to 26% of the cost of the panels and receive a credit.
