Most of the people that want to install solar panels on the roof of their homes think that all they have to do is install them, but they forget about testing them and then if something does not work properly they have to call for the installers again and this way they lose time and get stressed.

Solar panel testing refers to using an amp meter on the panel. Electricity is known to be measured in amperes. This thing can be done with an amp meter. Such a device will be attached to the negative and positive terminals on the solar panel and then the panel will be exposed to the sunlight. In order to protect yourself from injuries and secure the amp meter from any damage you should first rate the meter higher than the solar panel is. The amp meter will show you on its screen the short circuit current. This will be the amount of electrical current that you can expect from your panels to give. OF course it all depends on how strong was the sunlight so it would be indicted to perform your solar panel testing when there is a full sunlight outside.

Besides using an amp meter you can determine the power output of your solar panel by using another method that implies measuring the resistor’s voltage. For this solar panel testing procedure you will need a digital multi-meter (that measures the DC voltage) and multiple resistors. After getting all the needed measurements you can use this formula for calculating the power output: Current = Voltage / Resistance. After that you can make up a performance graphic by plotting the power output.

You should also know that a solar panel will transform the sunlight into DC (direct current) power not AC power as some might expect. This is why you need for the solar panel testing procedures a DC digital multi-meter.

Watts will be used for measuring the power that the solar panel generated for charging batteries for example or for using home appliances. The formula for calculating the power is Power = Voltage*Current. All you have left to do is to measure the amperage and voltage of your solar panel and plug the data into the equation. This way you will know exactly if the solar panel will be able to cover all the electricity you wanted it to offer you when you decided to install such a thing on your roof.

You will also have a solar charge controller that is meant for regulating the power that is brought by the solar panel to the rechargeable batteries. Such a controller has the purpose of by-passing eventual overcharges and to provide a good battery charge depending on the temperature outside. Besides solar panel testing you should also test the well functioning of this charge controller.

If you think you can not perform the solar panel testing on your own or you don’t have time for that call some panel installers and ask them to do this for you as it might save you from a lot of trouble later on.
