The following publish describes by means of calculations tips on how to choose and assess the right solar panel, inverter and charger controller combinations for obtaining optimal results in the form of free electricity.

For comfort, let's assume you have available a a hundred watt gadget you are aiming for to use with totally free solar power for ten hours every night.

To figure out precisely how large solar panel, batteries, charge controller and inverter you are required to have, watch the below circumstances.

1. Analyze the amount of electricity needed. 100 Watts x 10 hours = 1,000 Watt hours. Which happens to be the total power that is required.

2. Subsequent determine how large solar panel you actually need. Based upon a ten hour day of brightness, the approximation is self-explanatory:

1,000 Watt hours / 10 hours sunlight = 100 Watt solar panel.

The easy simple truth is that almost all the summer time days or weeks offer about 15 hours of sunshine and winter season you get approximately 4-5 hours of natural light. Almost always choose the most awful scenario predicament for

your solar panel. On those grounds, select a winter season day of sunshine.

1,000 Watt hours / 5 hours sunlight = 200 Watt solar panel.

(Depending on standard United States daily sunlight.)

3. Estimate the optimum size of the batteries which can be important. 1,000 Watt hours divided by 12 Volts = 83 Amp Hours of reserve battery power. 1,000 / 12 = 83.3

A standard marine deep cycle battery functions perfectly in this instance. Select much larger battery to be assured, believe 100 Amp hours power.

4. To calculate just how large solar charge controller you absolutely need, think about your solar panel energy specs, which is a hundred watts divided by twelve Volts.

100 / 12 = 8.3 Amps.

Desirably pick larger sized units, thereby use a ten Amp solar charge controller.

5. Know what power inverter can be utilized. That's the trouble-free element. You may want to energize a a hundred Watt load, consequently select an inverter including the

approximately a hundred Watts constant power standing.
