How To Test Efficiency Of Solar Panel

Touch the multi meter s red positive lead to your solar panel s positive wire.

How to test efficiency of solar panel.

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. Factors that affect solar panel efficiency. Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.

As most solar panels are 12 volts the solar panel test methods are basically the same. Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings the more efficient panel will produce more electricity than the less efficient panel. Solar panel efficiency is a measurement of a solar panel s ability to convert sunlight into usable electricity. 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. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. Then touch the multi meter s black negative lead to your solar panel s negative wire. Set the meter to above 200 vcd to ensure you get the most accurate reading possible.

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. You will want to ensure that you place the positive to positive and negative to negative when attaching your multimeter to the connection on the back of your solar panel. Step 3 measure current. Solar panels have been consistently increasing in efficiency at about 5 annually since 2010.

How much of the sun s energy hitting a panel is eventually converted into electricity is what is measured by efficiency. The efficiency depends on factors such as the intensity of the sunlight the solar cell s temperature and other external factors. What you need to know.
