On average, a 2000 square foot home would need a 4 kW system, which means 10 400-watt panels. As a precedent, LADWP calculates this type of average at 2 watts per square foot. Therefore, a 2,000-square-foot home would be allowed a 4,000-watt solar panel. Depending on the type of panel you choose, a system of this size would be 12 to 18 solar panels.
Keep in mind that this formula for calculating consumption varies depending on who produces your electricity. The average 2000 square foot home consumes around 1200 kWh of electricity per month. 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. In this scenario, you would only need 34 solar panels to cover your 17,500 kilowatts of electricity consumption.
The first step in determining how many solar panels you need is to calculate the annual kilowatt hour total. But how do you know precisely how many solar panels will be needed to generate 1000 kWh of electricity per month? The exact amount of energy your solar panels can produce depends on the amount of sunlight they receive, which in itself depends on the orientation of the panel and its location. This table shows how much electricity an average household uses in each region and how many solar panels in that climate are needed to generate that amount of electricity. Peak sunlight hours refer to when the sun is at its most prominent presence in the sky, and solar panels can produce electricity at close or full capacity.
Chances are that the family in House B will want to invest in more solar panels to reduce their electricity consumption than the couple living in House A. On the other hand, many solar contractors estimate solar energy costs based on the number of watts needed to meet their home's energy requirements. If you have a home facing east or west, you can expect your solar panels to produce around 480 kilowatt hours each year. If you're unsure of the solar potential, check the Global Solar Atlas to find out how much electricity is produced in various locations.
The main reason is that the amount of electricity that solar panels will generate depends to a large extent on the amount of sunlight you receive in your city. Solar panel estimates are not included this time, because these climates can be found in many different states. In this scenario, 37 solar panels would be needed to cover the 17,500 kilowatts of electricity consumption. Depending on where you live, the average 2,000 square foot home will need between 14 and 22 premium solar panels to meet 100% of your electricity needs.
