Calculate How Many Solar Panels You Need

Thousands of articles have been devoted to telling people the advantages of solar energy, but very few have cut to the chase and informed people how much the actual cost of going solar would be and how many panels they needed to generate enough energy To run their own homes.

We know that if you want to buy a solar panel system that meets the energy needs of your entire homes, you are about to pay over Rs. 2,50,000 for a small house and Rs. 4,50,000 for a large one. Anything up to. The question is ...

How do you calculate how many panels will be required if you are going to make them yourself?


- Start by looking at your current electricity bill. Find out how many monthly kilowatt hours you are using and divide that by 30 (average days in a month).

Now you have to find out how many hours of direct sunlight you have in a day. This information can be found through your local weather center. Now consider that you have an average of 5.5 hours as an example for your area.

- Use your average daily kilowatt hour and divide by the direct number of daylight hours for your area.

- Now that number is up to 1.15 (leakage and loss accounted)

If your daily use of energy is 40 kilowatt hours and you live in an area that has 5 hours of direct sunlight, then the amount of energy you get will be 9.2kilowatts or 9200watts. To produce more energy than you are consuming, you will need about 18 panels.

The cost of buying eighteen panels will set you back over Rs. 1,50,000 but you can build panels at around Rs. 15,000 each and add single panels to your original system when you buy them.
