Difference in Solar Panel Watts Explained

Many people would not know that the output of any solar panel installed either at your house or elsewhere is measured in solar panel watts.

Solar Power

With the advent of new technology and healthier and safer ways to produce energy, solar power came up as a worthy candidate to replace conventional power producing methods. With these prospects one could only begin to think that the world would be a greener place with no excessive pollution but statistics show that in the year 1998 it only contributed .02% to the total energy needs of the world. Having said that it definitely has grown in margin and a lot of people are now installing solar panels in their houses and places of energy needs to cut down on the costs and be a part of a greener earth

Solar Panels at home

If you wish to install a solar panel at your house you would first need to find the amount of panels you actually need that could suffice keeping in mind the amount of energy that you consume. After you have done that you need to use a mathematical equation which takes into consideration sunlight in your relative area, the power of the current and the voltage to calculate solar panel watts needed to meet your energy demands.

Solar Panel Watts

You also need to know that the output that a solar panel produces is measured in watts and the mathematical equation that derives this unit is:-

1 volt X 1 ampere = 1 watt

Calculating this is important because if you wish to run parts of your house using solar panels, you need to first calculate how much watts in total you use and then compare it to the amount of watts a solar panel can produce so you can see the relative cut down in electricity bills right in front of you.


Let’s assume that you use 100 watts of electricity every month and you wish to bring this down to 50% by using a solar panel. This would mean that you need 50 watts from a solar panel and this is where you do more calculations to see how many panels would be required to produce 50 watts of electricity. You could take a few panels and wire them together using parallel circuits or you could wire them together in a series depending upon the voltage required to produce the amount of watts.

Solar panel watts then can easily meet your power needs if you calculate and apply how much is needed; this would not only cut down on electricity costs, but would also make the earth a better place to live.

There is one con to this solution which is the initial installation cost, but the benefit definitely outweighs the cost and if you are aware of this then there is no reason for you not to install solar panels at your house and let the sun worry about giving you energy.
