Background
I'm working on a seismic alert network and seismograph station at my school in Puerto Rico. We're building a solar system for the system to continue running during a potential seismic event. The system only consumes about 10 Watts, but with the satellite internet equipment it might go...
Hi guys, I was looking for a few ideas for how to efficiently "power share" - the scenario is:
I will have some DC grow lights, about 36V (but this can be changed) 100w+ . I would like to get as much as possible of the power for these from one or more solar panels, and then top up the...
I'm not sure if this is the right place to post this, so please advise if this needs to be moved.
The question deals with 4 mis-matched solar panels on an RV roof. Yes, it is a bad design, but the RV mfg is no longer in business, so there you go.
I am somewhat knowledgeable on solar array...
Hi Everyone,
My aim is to build a simple solar powered pump with a rechargeable battery to water plants. The idea is to use a 6V 1W Solar Panel connected to a TP4056 (protected) to charge a 18650 Lithium Ion Battery. On the output is an MT3608 2A Boost Converter to step up the voltage to a...
Hello,
I am building Solar Guitar™ prototype, an eco-friendly, self-sustained musical instrument solely powered by the Sun:

10-15 watt, 2 speaker stereo guitar amplifier with reverb/chorus/delay/overdrive will be installed into the guitar’s body...
Hello great team!
I'd immensely appreciate the help of brilliant minds out here.
I've Solar rechargeable emergency unit that can power 2 lights and a small table fan. The unit stopped working with a blown resistor on the circuit. I did try replacing the resistor with an identical color coded...
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...
