Calculate solar panel battery charging time. The additional 10 is to make sure that the battery is fully charged. In theory to calculate the energy it can supply to the battery you multiply watts of the solar panel by the hours exposed to sunshine. The power generation rating of a solar panel is also given in watts. At a bare minimum most customers will have have a solar panel that can output two day of power in a single day and they will often select a battery that can withstand two days without solar and still not.

Solar pcu is a device through which you can directly connect your solar panel and your battery charging will start without any solar charge controller because it has a inbuild charge controller. Unfortunately we don t design systems for our customers but we do offer you the tools to design your own system. Then take the battery capacity which measured in ah and divide it by the amp rating the result from prior computation of the solar panel and then adding 10 of the charging time to it. Free solar battery calculator.

The next step involved in sizing your system and also in determining how to calculate solar panel battery and inverter is to size your charge controller but before then we have to understand some components which you probably have not encountered and so do not understand this will give you a better understanding of the calculation. Get a usb multimeter from amazon to verify your charge rate if you are connecting to an off the shelf battery pack there are a number of reasons that the charge rate could be worse. Batterystuff tech i would suggest running your numbers into the calculator. The final part to sizing your solar system is the solar panels.

I ll need a minimum of 5 hours run time with the solar panels charging the battery as i go. Hello swagatam i m trying to figure out roughly what i ll need in battery size and solar panel size. I ll be powering music amplifiers and laptop with a total draw of about 8 amps ac using a 1500w inverter connected to a 12v battery.
