Why we design this solar panel and battery capacity calculator?
We have designed a solar panel and battery capacity calculator to help people calculate how many solar panels they need and how much battery capacity they need.
For solar beginners, to design your own solar energy system you can follow our previous guide on how to build a solar energy system.
How do I use this calculator?
Before using this calculator, there are several parameters you need to know.
1, Daily electricity consumption
As stated in the guide, the first thing you need to know to design a solar system is your daily power needs.
2, the Peak Sun Hour for your area
Peak Sun Hour is the time of day when the solar panels receive all the sun’s energy equivalent to how many hours of the strongest sun light. If you don’t know your local Peak Sun Hour, here’s a reference list of Peak Sun Hours for each state in the United States.
3, The number of days the system can support in the absence of sunlight
On days when there is a lack of sunlight, such as rainy/winter days, the solar panels will only be able to support less than 40% of their capacity.
When building a solar energy system, you need to consider this in advance.
This requires increasing the battery capacity and the number of solar panels to extend the amount of time the system can support electricity.
Once you know your daily electricity demand / Peak Sun Hour / expected support days for your area, you can use this calculation to figure out the number of solar panels and battery capacity.
