Therefore, it is crucial to know how much energy your home uses before installing a solar system. For a daily energy consumption of 4 kWh, 16 solar panels of 250 W each would be needed for a 100% electricity supply. Let's say your property gets four hours of sunshine a day and you buy 325 watt solar panels. In that case, each panel can generate 1300 watt-hours per day (or 1.3 kWh).
Assuming your energy consumption is in line with the average of 29 kWh per day, you will need 23 325 watt panels to generate enough electricity for your home. From this calculation, you can estimate that a house with these energy requirements would need about 25 panels that produce 320 W. That is equivalent to about 20 to 25 solar panels to do the job. You can use this same formula to determine how many solar panels you'll need to power your home.
Or, you can use the easiest route, which is to review your energy bill to determine what you'll need. To find the number of peak hours of sunlight in your area, you can do a quick internet search that will return numerous results from databases and websites that can help you find that number for your area. For this example, let's say your area receives, on average, 6 hours of maximum sunlight per day. Now take the average daily energy demand figure of 33.33 kWh per day and divide that figure by the average of 6 hours of maximum sunlight you receive each day.
According to these estimates, your home will need to generate at least 5.56 kilowatts of electricity per day to reach 1000 kWh each month. Many solar experts will add 20 percent to this figure to compensate for unforeseen equipment, the environment, etc. Adding 20 percent to 5.56 kilowatts would bring daily electricity generation needed to 6.67 kilowatts. In general, the average solar system for a home consists of 20 to 25 panels, but the exact amount you'll need will depend on numerous factors, including where you live, how much energy you normally use, and how much energy your panels can generate.
Many variables influence the efficiency of solar systems, and it can be difficult to consider them when you don't have experience. While it is certainly possible to install a solar system and then have a solar installer add more panels later to accommodate increased energy needs, the most pragmatic option is to size your system as accurately as possible based on your expected purchases, such as an electric vehicle, swimming pool or power plant air system. If you have any questions or concerns about how much solar energy you may need for your home, you can always consult a professional solar installation company that can probably complete all of these calculations for you. In states like Arizona and New Mexico, which are known to produce more sunlight than northeastern states, homeowners are likely to need fewer solar panels.
Individual solar panels are capable of producing a certain amount of energy, depending on the conditions of your home (including how much sunlight you receive and how much shade your roof covers). Let's look at three key factors that determine how many solar panels you need to power your home, as well as an example of how to calculate the size of your system. You should also consider net metering when considering how much money you'll save and earn with your solar system.
