There are so many solar products in the market that consumers are unsure if they are getting a genuine product. As the demand for solar panels rises, more and more unqualified manufacturers are attracted into the business, using cost-cutting and substandard methods to make cheaper solar panels. In this article, you’ll be given useful tips to enable you identify genuine solar panels.

The use of substandard solar panels affects the amount of energy you get, therefore you won’t get your money’s worth of energy. It’s so unfair that these distributors sell substandard products at a very high price. Its com mon practice to tamper with the wattage making you pay more for a lower wattage. In order to protect yourself against tampering, check the power rating inside the glass frame and ensure it matches with the rating on the box.

Properly testing your panel before installation is an important step that most solar buyers skip. This will help ensure that you do not hastily install panels that you’ll soon take down and fix. The panel can be tested with a multimeter. To test the solar panel voltage output, put your solar panel in direct sunlight, set your multi-meter to the “volts” setting, then touch the multi-meter’s (red) positive lead to your solar panel’s positive wire and the multi-meter’s (black) negative lead to your solar panel’s negative wire. This will give the voltage reading on the multimeter.

To test solar panel current output, put your solar panel in direct sunlight, set your multi-meter to the “amps” setting, then touch the multi-meter’s (red) positive lead to your solar panel’s positive wire and touch, the multi-meter’s (black) negative lead to your solar panel’s negative wire. This will give you the amperage reading of the panel. With these two values, you can easily calculate the power output using the formula

Power(W) = Current(A) * Voltage(V)

Solar panel testing will ensure that you get the wattage you have paid for. It is also important to look for the relevant mark of quality on your solar products. It’s a lot safer to buy from a reliable company like Powerbug with a very good track record. When you buy from such a company you have access to warranty programmes.
