Whenever you need reliable solar panel cleaning services, you should compare local contractors and pick the right one for your needs. Ideally, you should not rush your decision as you need to consider all the key factors before making your decision. Read on to learn more about cleaning of solar panels.

Why Clean Solar Panels?

Solar panels are normally installed outdoors, either on the roof or on a stand on the ground. This means that they are exposed to the elements. Leaves, dust, insect carcasses, bird droppings, cob webs and other types of debris can find their way onto solar panels. When it rains, water will mix with the debris to form mud. This will make it difficult for sunlight to get to the surface of the panel. That is why regular cleaning is recommended. When panels are cleaned regularly, you can expect to harness enough sunlight. Consequently, the efficiency of the system will increase considerably

Choosing a Cleaner

There are many contractors that can clean solar panels effectively. Since they are not all the same, however, you have to consider the following factors as you narrow down the search:

i) Licensing

The ideal contractor must have a valid license to offer solar panel installation and maintenance services. Any firm that does not have a valid license should be avoided as they may be quacks. When you choose to work with a licensed professional or firm, you can be assured of getting quality services.

ii) Insurance

Solar panel cleaning services entails climbing up the roof. This can be risky. After all, the contractor can fall to the ground and get injured. The contractor can also cause damage to your panels or roof. For this reason, you should only shortlist contractors with a valid insurance policy and performance bond. This will help to protect you from liabilities.

iii) Cost

Obviously, different firms are going to charge different rates for their services. Therefore, you need to request quotes and compare them to identify the most affordable contractor for your needs. The most affordable and most competent service provider should be given preferential treatment. After all, they offer better value for money.

iv) Guarantees

The best cleaners usually offer guarantees and warranties. Therefore, you need to check whether or not a firm offers guarantees and warranties before making a decision. The ideal firm should offer a customer satisfaction guarantee or 100% guaranteed services.

v) Reputation

You have to do some research to learn more about the reputation of a service provider. This will go a long way in helping you make the right decision. Read reviews, testimonials and ratings before making a decision.
