The solar panels are generally installed at the rooftop and in open areas. Because of this it can face various changes such as dust, rain, grim, bird droppings and other environmental elements. It becomes vital to maintain the solar panels, since insufficient care might lead to decreased efficiency or damage to the system and may nullify your overall investment.
Since the sunlight is main source for working of the solar panel, it should be cleaned so that it can absorb sun energy to its optimum. If the panels are properly cleaned and maintained, then it can even last up to two decades. Moreover, the panels require minimum maintenance without any special tools and equipment. Let us see few tips on maintaining the solar panels.
Using Cleaning kit:
There are readily available solar panels cleaning kit available in the market. The kit consists of liquid soap, set of brushes (small and with longer handle), wiper and other necessary accessories. The liquid soap is specially meant for cleaning the solar panels. However, the cleaning kit can substituted with your car cleaning kit as the liquid soap is similar with the car cleaning liquid soap.
Mix the liquid soap as per recommended quantity in water and mix well. Use small brush to reach the corners of the panels or with large handles depending on the size of the panels. Gently rub over the solar panels without applying more pressure or use sponge instead taking care not to damage the panels.
Wipe out the panels:
Once the panels are cleaned with liquid soap, they should be wiped out immediately before the soap dries out. If the soap dries out, then it will not be able to absorb the sunrays and decrease the efficiency of the solar panels.
Monitor the panels:
Besides cleaning, the efficiency of the panels should be monitored on regular basis to enable you to make corrective action. This can be done by appointing professional monitoring system that will enable you to monitor the system on the go with other parameters to keep your panels healthy.
Check the PV modules:
The PV modules should be inspected regularly to verify the physical defects such as fractures, browning, frame corrosion, moisture penetration. The connections and terminations at the junction box can be verified and don’t require professional services to verify them.
The mounting structures though do not require regular checks, but should be checked at least once a year as the environmental elements might damage them or needs repairs. The bolts and fastening devices may loosen over a period of time.
Shading of the panels:
You should check the shading of the panels to ensure there is no blockages on the panels because of shades of the buildings, tree etc.
Check electrical characteristics:
It is necessary to check the integrity of the fuses, protective devices besides open circuit voltages and short circuit currents. The solar array isolation device should be inspected and necessary repairs should be done immediately.
