Although a solar panel will typically last for 20 years on an average, it does need some periodic attention that includes everything from on-schedule cleaning to some preventive maintenance works. Whether you are happy with the upkeep offered by your manufacturer as part of the purchase contract, or you would like to hire a third-party agency to service your unit at regular intervals, make sure that the maintenance contract covers all areas that decide your solar power system’s health and longevity. Here are the four points that you must include in your solar deal:
Service Providers’ Credentials
If you are availing the service of a third-party agency, make sure that the contract paper has the license number of the contractor printed on it. This gives you the peace of mind that your expensive unit is in safe hands.
Payment Details for Subsequent Years
As far as the solar PV systems are concerned, maintenance costs are higher for the smaller units (two percent of the initial system cost) and lower for larger units (one percent of the initial cost). However, maintenance and cleaning costs may rise as the system gets older. Ask your service provider what maintenance/repairing expenditure you should expect going forward.
The Frequency of Site Visits
Besides the scheduled visits for cleaning and other maintenance tasks, the contractor should also visit your site once a year to check whether your unit is generating electricity as expected. Other visits in between are for detailed visual inspections of electrical components and taking care of repairs if needed. Make sure that your contractor inspects the inverters to ensure that they are functioning at their peak efficiency.
Besides on-site visits, you should also opt for offsite electronic monitoring services for real-time performance evaluation. The advantage of this service is that you can address all the issues at the earliest. These types of services help you save on repair costs in the long run.
While purchasing your solar PV system from a company, don’t take the word of mouth or e-mail communication as a legally binding assurance for future services; get it in black and white. Check if all the after-sales services are clearly mentioned in the agreement.
