The average 2000 square foot home consumes around 1200 kWh of electricity per month. On average, how many kilowatt-hours (kWh) do you consume per month? (See your electricity bill) Based on the results of the solar panel calculator above, you can multiply the recommended wattage by 65 or 75 cents (or more) to get an approximate cost for all of your solar panels. A solar energy system that could produce 2000 kWh per month would consist of 27 to 66 standard residential solar panels. The amount of solar energy, or the number of solar panels you need, will depend mainly on your location.
First of all, you need to know the energy consumption of the property. You can find this using 12-month energy bills. Add monthly kilowatt-hours (kWh) for an annual total. If you don't have electricity bills, there are other ways to create a budget.
Request the solar design service and we can help. Once you know the desired kWh, use the calculator here to determine the kilowatts (kW) of solar energy you'll need to generate kWh. Installing your own solar panel system is easy when you have a team of experts to help you every step of the way. SOLAR HOURS PER DAY The next information to consider is the solar hours per day for your location.
You can get a better idea of the specific performance that can be achieved at your location by consulting reliable sources such as the World Bank's solar maps or the solar radiation database of the National Renewable Energy Laboratory. If your goal is to produce 2000 kWh of energy per month, you'll need to do some quick calculations to determine how many solar panels you need. The table below assumes an average irradiance value of 4 peak hours of sunshine and an individual solar panel size of 300 watts. RENOGY is rapidly becoming the source of choice for solar panels, kits, batteries and solar control accessories.
First, solar panels do not produce the same energy in all locations, but rather rely heavily on the irradiance, or energy of the sun, in your geographical location. The annual production of each solar panel is higher in states such as Arizona or New Mexico, which receive a greater amount of sunlight than less sunny regions, such as New England. The following calculator calculates the number of solar panels you need, based on your monthly energy consumption and the average number of peak hours of sunshine you receive each day. The solar map uses insolation, a measure of the energy of solar radiation received in a given surface area at a given time.
To calculate the size of your solar system, you'll need three pieces of data to calculate solar kilowatts. You'll notice that some solar panels are described as residential, while others are described as commercial. After calculating how many solar panels power a house, the next step is to calculate the roof area needed for their installation. When deciding how many solar panels you need for your home, especially if you are going to install a large system, you need to consider how much weight your roof can support.
A domestic solar panel weighs about 20 kilograms (44 pounds), which means that 30 of them will add about 600 kilograms (1323 pounds) to your roof.
