How much solar energy does a 2m by a 3m solar panel convert to energy on a sunny day? Assume that the solar cells are 30% efficient.I'm not looking for the answer so much as I need an explanation o how to solve this type of problem... Thanks!!
A watt is the fee at which vigour is produced. It's analogous with horsepower, hp = 745W= 33,000 toes-lbs per minute. So the wattage of a sunlight panel is the capacity of the panel to drive a procedure like run a motor or power a radio. General energy calculations are a part of the bigger class of Physics.
You have the area of the solar panel. You know their efficiency. What you need to know now is the energy (per area) delivered by the sun. The energy delivered by the sun can be found on the internet. Earth ,43 – ,32 W/m? (wikipedia) That is offcourse for your solar panels perpendicular to the ray's of the sun. If they are under an angle you should see what the area of the projecton of your solar panel is on a plane perpendicular to the ray's of the sun. So know you have the intensity W/m? and an area (or effective area). Here you go the energy deliverd by the sun. And 30% of it is what you get out of your panels.
