Did you know that solar energy is considered the most abundant energy resource on earth? That’s because there are 173,000 terawatts of solar energy that strike the Earth. 

If you’re looking to understand more about the most efficient solar panels, then you’ve come to the right place. This article will take a look at what you need to know about efficient solar panels. Read on to explore more about solar shopping to ensure that you buy the right solar panels for your needs today. 

Understanding Solar Panel Efficiency

When you’re looking to estimate your savings, it’s important to understand the average efficiency of solar panels and how much sunlight will hit the surface area. This is what converts into usable electricity. 

The higher the rating, the more sunlight that can be turned into electricity. This means that if the efficiency rating is 20%, your solar panel can convert 20% of the sunlight it receives. 

Calculation Time

As you’re shopping for high-efficiency solar panels, you can take a look at the datasheet to see the solar panel’s efficiency. In order to understand the calculations, they’re figured out by using the operating temperature with solar irradiance, and 1,000 watts per square meter. 

You’ll need to divide the power rating by the area of the panel x the irradiance, x 100. Keep in mind that the temperature and irradiance level will change based on the panel’s efficiency. 

Cost vs Value

The more efficient the solar panels are, the more they normally cost. Take a look at the upfront costs and see if the difference is justified. It might wind up saving you more in the long run since they’ll last longer. 

Solar Panel Efficiency Determinates

The determining factors of the efficiency include the reflection, material, wiring and busing. The reflection is when the light reflects away from the solar panel and will lower the efficiency. 

The glass layer will reduce the effects from the reflection. The type of material plays a factor too whether it’s polycrystalline silicon, monocrystalline silicon, etc. Wiring and busing are what captures and transfers the electricity that determines the efficiency. 

There can also be other factors such as multifunction solar panels which means it’s able to absorb variable wavelengths of light. Solar panels that can absorb light on both sides of a cell are known as bifacial solar panels. 

Equipment Options

Take a look at different installers in your area to determine your system’s electricity production. You can then determine the different savings and costs from different equipment packages.
