What are the components of a solar panel system ?

We Answered:

A solar electric array consists of photocells, conducting wires, batteriy to store the electric energy, and the support structure to hold the assembly.

A solar water heating array consists of panels dark in color to maximize their heat absorbtion with water circulating pipes, a pump, a storage tank, various shutoff valves and piping, some device(s) to use the heat energy generated by the system (like hot water furnace coils or using the system as a preheater for domestic hot water), and the support structure to hold the assembly.

if I want to power a 500 watt air conditioner, what watt solar panel system will I need?

We Answered:

Depends on how long you run the A/C. Let's use 500W of panels as an example. Consider the fact that the panels are generating power at 500W rate for about 6 sun hours a day in the summer (depending on where you are). When you figure in losses, if you run it for 4 hours, 500W of panels may do it. 500W x 4 hours = 2000 watt hours (or 2kwh) needed, 500W panels x 6 sun hours -35% losses = 1950wh generated.

You can calculate how much you would need in panels and batteries on an off grid calculator like this, http://www.altestore.com/store/calculato… If you are planning on staying connected to the grid, but want to offset the amount of power the AC uses, you can go to a grid tied calculator like this, http://www.altestore.com/store/calculato…

How can I obtain a solar panel system?

We Answered:

I found this site to purchase on-line. It's under $50 & may be worth a try.

EDIT: Wrong link. This one shows Do it Yourself from hardward store supplies. Scroll to 1/2 way mark on page to square labeled "System #1: Solar Power System"

Note this panel will provide you with electric energy & is not a panel that requires outside energy source to power a pump. It's also portable to remove & take camping & still power up a lap top PC
