How to maximize the life of your solar panels

One of the biggest benefits of having a solar energy system is they require minimal care. Since there are no moving parts, solar panels and their installation experience minute amount of degradation with time. It was expected that solar panels lose around 1% of effectiveness per annum. With advancements in manufacturing technology, their life expectancy has improved even more. Modern generation solar panels are expected to maintain up to 92% efficiency even after 20 years.

As a homeowner, what steps can you take to maximize the life of your solar panels? Consider the following tips:

Regular Inspection

Solar panels for home is typically installed in high locations, therefore they are not susceptible to ground-level damage or debris. This doesn’t mean you should avoid a close-up inspection of your panels. You want to make sure your panels are not losing power because of a build-up of tree material or pollen. This is the same type of debris that accumulates on doors and windows.


Regular Cleaning

In a majority of cases, rain is all you need to clean your panels. In areas where there is minimal rain, there are good chances that the panels have built-up dust and debris. In such cases, a hose spray is sufficient to give your panels a good clean.

The main concern is the presence of scratches. This can reduce the amount of light entering the solar cells. Therefore when selecting a product to clean your panels, ensure it is a non-abrasive cleanser. To wipe down the panels, use a cotton duster.

Monitor regularly for shade and sun

For solar panels to do their job, they must face the sun for as long as possible. With time, new construction projects and tree growth can alter how much sun exposure your panels get. This is why it’s absolutely necessary to constantly monitor the sunlight orientation of your solar panels.

Check Energy Usage

When you set up your solar panels, you may have an arrangement with your utility company to show how much energy you’re sending back to their grid. However, this provides no indication about the energy output of your panels. The solution is to install an energy monitor. There are different types of technologies that enable energy consumption. Inverters display basic information about power output and daily/cumulative data. Sophisticated inverters translate kilowatt-hour information into the amount of carbon dioxide that you’re preventing from entering into the atmosphere. There are also phone apps that provide remote data on the performance of your panels at a given time.
