As with the traditional electrical system, there are basic equations. Other than the basic equations for home electricity, there are equations used to determine amounts of electricity produced by solar radiation; and solar panel area needed to produce a certain amount of energy.
Of course, we should start at the beginning with the standard electrical definitions and equations. Newton of force is the force used to move 1 kilogram (about 2 pounds) to the speed of 1 meter per second while the force is applied. A Joule is the amount of energy exerted to do work with 1 Newton of force. Energy is measured in Joules. Power, also known as watts, is the amount of energy divided by time (usually seconds); in other words joules per second.
With these basic definitions, the following equation is the basis of all electrical equations:
Power (watts) = Energy (Joules) / Time (seconds)
Energy (Joules) = Power (watts) x Time (seconds)
Time (seconds) = Power (watts) / Energy (Joules)
When dealing with solar power, this basic equation is modified to collect all necessary information. Area is measured in meter(s) squared (m2). This is done because the most needed information, when dealing with solar power, is area covered by solar panels for the amount of electricity desired. Another change is the addition of a constant. The constant is 150 watts divided by 1 meter squared. After looking the equation the similarities are visible:
Power = (Area of solar panels in m2) x 150 watts/m2
We have the basic power equation. There is something missing. Due to the rotation of the Earth, Sunlight shines in the same location for about 12 hours. Because of this, the length of time solar radiation hits the solar panel(s) must be added into the vacation:
Power = (Area of solar panels in m2) x 150 watts/m2 x (Hours of sunlight)
Knowing the basic math of Solar Electricity, we are able to determine the amount of solar panel area and/or electricity being produced.
