How To Test Solar Panels Without Sun

You will need a solar panel tester known as an amp meter.

How to test solar panels without sun.

To get an accurate measurement you will need to ensure that your panel is in full sunlight when you test. When you buy solar panels you need to check quite a few things to make sure you are getting the right kind including checking the solar panel output buying and installing solar panels requires some research to determine how many you need to get enough output to satisfy your electric needs. Then touch the multi meter s black negative lead to your solar panel s negative wire. The panel collects energy from the sun thus solar power and converts it into useable power for the batteries or lights to turn on and run for a few to several hours.

Place the solar panels directly underneath a household light to charge them as quickly as possible without sunlight. If it s not there is a problem with your solar panel output. Disconnect the panel from any regulator if testing an array you will need to test each panel individually. There is no simple way you can check the for maximum panel output.

To measure the amp output of your solar panel you will need to attach the meter to the positive and negative. To accurately test a solar panel you need to find the open circuit voltage and short circuit current paying mind to the cell temperature ambient temperature coefficient and the angle towards the sun. Of course solar power is far more complicated than this simplified view but the basics are what most of us need to understand about solar power and how it affects. You can use a 100w lamp and move it over each cell to see if the output of each cell is about the same.

The volt reading on your multi meter should be close to or just under 60 volts. The further away it is from an incandescent light bulb the longer it will take your solar panel to charge.
