PV Gap

Shawn Said:

About solar energy I think...?

We Answered:

Sorry, there was no question.

Solar energy is limited by the solar constant, as well as by latitude and obscurance. It is generally most needed where least available, and vice-versa.

One of the most effective uses of solar technology for home heating is to build a house that's insulated for solar heating, and then to not install the solar equipment. The greatest payback often comes from the insulation alone.

I'm sorry if my lack of answer does not match your lack of question.

Jerome Said:

how long will a 15 volt.15 amp photovoltaic in series take to charge a 12 volt battery?

We Answered:

A 1-2 amp charge is considered a trickle charge. If I were you, I'd go for another couple of PV cells. Then connect them in parallel to increase the amperage. The 15 volt is under ideal circumstances so don't worry too much about that.

Make sure that all cells are installed the same way and install a diode and a fuse on the connection to the battery.

Make sure that the diode can handle the amperage without burning up!

Also, when you are installing your system wear safety glasses. In the event that you make a mistake there could be a short circuit and the battery could vent acid and hydrogen. It's a simple safety step that's worth taking every time.
