Question:

Solar panel battery charging?

So idk how to connect a solar panel to a battery ...is it like a series connection from the solar panel to the battery, or a parallel connection from solar cell to battery? (to charge) please and thank you

Answer:

I agree, you should get a charge controller and install appropriate fuses.
it depends how big the panel is. a small trickle charger (like a 2W panel with built-in diode), just connect + to + and - to - (parallel) to trickle charge the battery. The diode will keep the batter from discharging through the panel when there is insufficient sunlight. for a large panel (like a 220W 24v panel), you best go through a charge controller. the charge controller has 2 leads for the solar panel input, 2 leads for the battery connection and 2 leads for the 2v load. just follow the instructions to connect the panel and battery to the controller, and MAKE SURE YOU USE THE REQUIRED FUSES. very straightforward stuff -- just RTFM
