Whether you’re looking to save on energy bills, reduce your carbon footprint, or simply want to get the most out of your solar panel system, this blog is for you. So, if you’re ready to know how to increase solar panel efficiency, keep reading!
5 Best Methods to Increase Solar Panel Efficiency
Increasing the efficiency of solar panels can lead to more electricity production from the same size panel, reducing the overall cost per unit of energy generated. There are several methods to increase solar panel efficiency, let’s get started!
1. Choose One of the Most Efficient Solar Panel Models
Photovoltaic cells are cells that convert sunlight into electricity. Solar panels are composed of photovoltaic cells. It would be amazing, but a solar panel cannot transform all the solar energy it receives into electricity.
The efficiency of a panel is therefore the amount of energy that hits the panels and converts them into electricity.
In the last five years, solar cell technology has advanced a lot. The average solar cell efficiency has increased from 15% to 20% over the previous years. But not all solar panels work the same. The material and structure of each model will determine its efficiency and price.
Even though the initial cost of solar panels will be higher, it is worth investing in the most efficient commercial models if you want to get the best results. Sunpower and LG are producing some of the most efficient commercial-solar panel models in 2023. Their efficiency is around 22%.
2. Choose Panels With High-Concentrated Photovoltaic (CPV) Cells
CPV works by focusing sunlight onto a high-efficiency solar cell. Otherwise, it would be too costly to use. Traditional solar panels have a peak efficiency of 22%, while CPV panels use cells that can achieve 46% efficiency.
But, efficiency comes with a high price. CPV panels can be up to 4x as expensive as traditional PV panels.
There aren’t as many CPV models available as traditional PV. It’s worth looking into CPV if there are suppliers and you have the funds to invest upfront.
3. Avoid Installing Solar Panels in Shaded Areas
Because solar panels produce electricity from sunlight it is natural that shading can reduce the output of electricity. Many people don’t realize the impact of shade on solar panels.
Even one photovoltaic cell can shade its neighboring cells, affecting the energy they produce. It acts as a resistor.
Shade solar panels are most difficult to shade if there is a tall tree or other building nearby. It is important to spend time in the planning phase to assess a site to ensure the shade is not an issue.
4. Choose an Expert Solar Installer
Solar panels that aren’t properly installed won’t get the maximum amount of sunlight and generate less electricity.
When installing solar panels, the first thing to think about is the orientation and angle. Solar panels should be placed at an angle of 18 to 36 degrees in order to get maximum sunlight exposure. Your solar panels should face south if you are in the northern hemisphere. If you are in the southern hemisphere, your solar panels should face north.
Ironically, solar panel efficiency can also be affected by temperature. As the temperature rises, solar panels’ effectiveness can decrease. During installation, sufficient space should be allowed between the panels and the roof. This allows for air movement and helps prevent your photovoltaic panels from overheating.
To get the best out of your solar panels, it is worth consulting expert solar installers.

5. Clean Your Solar Panels
Solar panels are very easy to maintain because they don’t contain any moving parts. It is important to clean solar panels regularly as dirt and dust can build up on the surface. This will eventually reduce efficiency.
Depending on how often it rains, and how expensive it is to have your panels cleaned, there are a few factors that will determine how often you need to clean them.
Dust and dirt can cause a 5% drop in output over the course of a single year. If they are very dirty, such as in an area that doesn’t get enough rain, the output loss can reach 20%. It is recommended that solar panels be cleaned at least once per year.
In conclusion, increasing the efficiency of solar panels is a crucial step in making solar energy a more practical and widespread source of renewable energy. Regular maintenance and cleaning can also play an important role in ensuring that the panels are operating at maximum efficiency. By combining these techniques, we can make significant progress in increasing the efficiency of solar panels and paving the way for a more sustainable and cost-effective future powered by clean, renewable energy.
