Use our complete solar panel calculator to help you make an informed and data-based decision. Using the latest solar intensity data for your area, our tool can model the output of your system with 96% accuracy, helping you to understand just how beneficial solar panels could be for you and your energy bills.
Divide the actual solar panel capacity by the capacity of a single panel to determine the number of panels needed. For example, if your average daily energy consumption is 30 kWh and the system efficiency is 80%, and you have an average of 5 hours of sunlight per day, you would calculate your daily energy production requirement as follows:
Our solar energy calculator answers this with precision. By taking into account factors such as your location, roof orientation, and solar panel efficiency, our tool accurately calculates your annual energy output from solar panels. But it doesn't stop there.
To find the solar panel output, use the following solar power formula: output = solar panel kilowatts × environmental factor × solar hours per day. The output will be given in kWh, and, in practice, it will depend on how sunny it is since the number of solar hours per day is just an average. How to calculate the solar panels needs for camping?
For the exact solar panel computation, take your location, weather conditions, panel size, system efficiency, and derating factor as discussed in the blog into consideration. Divide the total monthly energy needs (1000 kWh) by the number of days in a month and divide by the panel output to get a precise estimate.
We will also calculate how many kWh per year do solar panels generate and how much does that save you on electricity. Example: 300W solar panels in San Francisco, California, get an average of 5.4 peak sun hours per day. That means it will produce 0.3kW × 5.4h/day × 0.75 = 1.215 kWh per day. That’s about 444 kWh per year.
