What is a solar panel?
PV panels are generally referred to as solar panels that are used to convert thermal energy from the sun into electricity, that can be used to power electrical loads. These panels can be used for a range of applications such as powering remote systems for telecommunication, cabins, remote sensing as well as the most common use which is production of electricity for and by residential and commercial solar energy systems.
These panels collect renewable energy in the form of sunlight and convert this thermal energy into electricity which can be used to provide power exactly as other sources of electricity
How to maintain solar panels?
Solar panels require very little maintenance after installation and hence are considered to be an extremely cost-effective method of generating electricity. However, they need to be cleaned regularly as their efficiency reduces vastly due to accumulation of dirt, dust and soiling on the panel face. Inadequate cleaning can reduce the efficiency of solar panels from 10 to 35%. To maintain the output of electricity generated by the panels they need to cleaned periodically especially if they are placed in areas of high airborne particles or in Industrial sectors where the dust and debris is higher.
The solar panels can be cleaned in various ways:
- Using a Hose: if the main cause of build-up on the panel is dust and dirt, then a simple hose down of the panel is enough to clean it entirely. Spraying the panels entirely with water using a garden hose will help in thoroughly cleaning up the panels. They can be dried naturally in sunlight. The only thing to keep in mind is the pressure on the hose should not be extremely high as it may damage the panels or lead to unwanted scratches which will lower the efficiency of the same.
- Scrubbing the solar panels: If the solar panels have sticky substances that can not be cleaned by just using water like bird droppings, then the panels can be scrubbed to be cleaned. The panels should be gently scrubbed to avoid scratches or any damage. A soft scrubber brush, sponge or similar tool can be used with mild soap and water. It is essential to note that the soap should contain as little chemicals, since certain chemicals may react with the panel materials and damage them entirely. Warm water can be used to clean the panel after scrubbing with the soap mixture and the panel can be left to dry in natural sunlight.
- Professional service: Generally, the manufacturers of most solar panels offer a service period where professionals will clean the panels and batteries. The company offers this option during purchase itself, and it is a goof way to keep up with the maintenance of the panels. They also help in checking if all parts are functioning as per requirement and prevent any malfunctions in the future.
Cleaning the panels is as important as scheduling when to clean the panels. It’s best to do the cleaning during the day time so that the panels can dry thoroughly with the sunlight. Regular maintenance is important, but it is also essential to not over clean the panels as certain parts may begin to rust. Its best to check with the manufactures about the frequency of maintenance and to follow their suggested schedule.
