If you want to understand your own energy consumption, the best way to do it is to review your total energy consumption for the past twelve months in your utility bills. Most utility bills provide this information, so you can easily divide that number by 12 and get a good estimate of what you'll need your solar panels to generate each month. To get an even more accurate result, you should also consider your average power requirements and current power consumption in watts. Once you have all the necessary information, you can start calculating the size of the solar system you need.
To do this, you'll need to know the total watt-hours per day that your solar system needs to produce. This number is calculated by multiplying your average daily kWh usage by 1,000 (the number of watt-hours in a kilowatt-hour). Then, divide this number by the number of peak sunlight hours for your area. This will give you the total wattage that your solar system needs to produce each day.
Finally, multiply this number by the number of solar panels you need to install. This will give you the total wattage of your solar system. To get the size of each panel, divide this number by the wattage rating of each panel. This will give you the total number of panels needed for your solar system.
By following these steps, you can easily calculate the size of solar system you need for kWh per month. Knowing this information will help you make an informed decision when it comes to choosing and installing a solar system.
