Hi everyone, I plan to build a high capacity 3.7V/5V solar charging powerbank (something like 10-15ah). I’m going to use modules of TP4056 breakout board each coupled with two 18650 cells in parrallel. But I was wondering what would it need to charge two or three of these TP4056 modules with a...

I think there is a gap in the market for a new electronic device. The device should power a simple resistive water heating element using the energy from a solar PV array. This will allow for cost-effective and environmentally sound water heating. The device will use maximum power point...

Hi there, I am looking at installing a solar and wind energy system on a house. The solar panels produce DC and the wind AC but the winds AC is passed through a controller which converts it to either 24 or 48VDc. Therefore both solar and wind will be producing DC. I intend for this to be an...
