Therefore, a 2,000-square-foot house would be allowed a 4,000-watt solar array. Depending on the type of panel you choose, a system of this size can be from 12 to 18 solar panels. As a precedent, LADWP calculates this type of average at 2 watts per square foot. Therefore, a 2,000-square-foot house would be allowed a 4,000 watt solar array.
Keep in mind that this formula for calculating consumption varies depending on who is producing your electricity. The average solar installation will require between 335 and 405 square feet of roof space. To find out how much roof space your solar system needs, simply multiply the number of panels you need by 17.55 square feet, which is the area of most residential solar panels sold today. Keep in mind that this formula for estimating consumption varies depending on who provides you with electricity.
The average 2000 square foot household uses about 1200 kWh of electricity per month. If you have a home facing east or west, you can expect your solar panels to produce around 480 kilowatt hours each year. Since you now know how much 1 kW of solar energy you will produce in your area, you can determine what size of solar system you need to meet your electricity needs. Assuming that a single panel generates 45 kWh per month and that the average US household uses around 900 kWh per month, you will need approximately a minimum of 20 solar panels to cover all your electricity needs.
Assuming you use about 37 kWh per day, you would need about 37 solar panels to meet 100% of your average energy needs. Whether you live in Tempe, Scottsdale, Surprise, Litchfield Park, Tuscon, Ajo, Phoenix, Mesa or anywhere else in Arizona, Alternative Energy, LLC can help you with residential and commercial solar panel installation. The main reason is that the amount of electricity that solar panels will generate depends largely on how much sun you receive in your city. Solar panel technology has advanced rapidly in recent years, resulting in several consumer-quality panels that are highly efficient.
Depending on where you live, an average 2,000-square-foot home will need between 16 and 25 premium solar panels to meet 100% of your electricity needs. This site provides homeowners with information on the most effective solar products and provides access to expert solar installers and manufacturers. Next, solar expert Will White discusses everything you need to know to find out how many solar panels you need to power your home. So, when we divide our total consumption by the expected output of a solar panel, we see that approximately thirteen solar panels of this size would be enough to power a house of that size.
