6 Ways to Improve Solar Cell Efficiency

Why is solar cell efficiency so important? The energy that is radiated by the sun onto the surface of the Earth exceeds the global consumption of energy in a year. Solar cells convert the light that is available into electrical energy. This is done without the aid of any moving parts or chemical reaction. It is important that this energy is harnessed in an efficient and cost-effective manner. Thus, maximizing solar cell efficiency becomes necessary. Here are a few ways you can improve the efficiency of your solar cell to obtain the maximum output.

Make an Informed Decision

The most important thing you can do is to make an informed decision while purchasing a solar panel. By doing this, you can find out which system offers the best value for your money as well as ensure that you get the best output from your solar system. Check out newer models of solar cells that give you improved levels of energy conversion. These models incorporate at least two layers of materials that are not similar with dissimilar sensitivities of wavelength.

Use a Solar Concentrator

Solar light can be concentrated with the help of a solar concentrator. The purpose of these concentrators is to concentrate the light falling on a large area to smaller areas. Large mirrors or other devices are used in the facilitation of the task. Thus, the overall efficiency of solar cells, which are generally very expensive, can be increased. You not only get more energy but also save money.

Correctly Install Your Photovoltaic Panels

Photovoltaic panels should be installed correctly. The orientation, as well as the angle it tilts at, should be right. This would ensure that the panels receive optimal sunlight all through the day, as well as all through the year. The orientation of your solar panels should be more toward the true south if you live in the northern hemisphere. Similarly, they should be facing the north if you are in the southern hemisphere. The panels should be tilted in such a way that they receive sunshine directly without any obstruction from 9 a.m. to 3 p.m.

Avoid Shaded Areas

Ensure that your solar cell is not shaded as this would have an adverse effect on the power output. This is especially true when you connect your solar cells in a series. If a photovoltaic cell is shaded, it causes the energy that is generated by its neighbors to be drained. This is because it acts as a resistor and helps in determining the total current.

Keep Your Solar Panels Clean

If dust accumulates on the glass surface of your solar panel, it reduces the panel’s efficiency. As a result, the sunlight that would normally reach the photovoltaic cells gets dissipated. It is therefore important that you ensure that no dust and dirt collects on the surface of your cell.

Prevent an Increase in Temperature

The efficiency of your photovoltaic panel is affected by temperature levels. Efficiency drops as the temperature gets higher. Care should be taken that there is a sufficient gap between the solar panels and the roof, as this allows easy movement of air and prevents the heat from affecting your photovoltaic panels.
