How To Test Efficiency Of Solar Panel

As long as the amp meter is rated higher than the solar panel you will be able to measure the output effectively.

How to test efficiency of solar panel.

The electrical power produced is a product of current and voltage. Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity. Solar panel efficiency is a measurement of a solar panel s ability to convert sunlight into usable electricity. Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight.

Then touch the multi meter s black negative lead to your solar panel s negative wire. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. The efficiency depends on factors such as the intensity of the sunlight the solar cell s temperature and other external factors. Step 3 measure current.

To calculate the efficiency of your panel just multiply the amount of sunlight that hits the earth s surface in your area known as the incident radiation flux by the area of your panel measured in square meters. Set the meter to above 200 vcd to ensure you get the most accurate reading possible. How much of the sun s energy hitting a panel is eventually converted into electricity is what is measured by efficiency. As most solar panels are 12 volts the solar panel test methods are basically the same.

Factors that affect solar panel efficiency. Solar panels have been consistently increasing in efficiency at about 5 annually since 2010. Most solar panels have efficiency ratings of around 15 to 18 percent. Testing solar panels for volts to test solar panel voltage output put your solar panel in direct sunlight set your multi meter to the volts setting and.

What you need to know. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. So if a solar panel has an efficiency rating of 15 that means 15 of the sunlight that hits the solar panels will be converted into electricity.
