“solar panel cleaning is generally not necessary”, according to EnergySage. Nr.1 award winning independent solar cost comparison site in United States. 

After all, solar panels are designed to be outdoor for over 25 years and in general the rain will wash the dirt.

However, it will help in some cases, for examples:

  • You live in a particularly polluted area
  • There are bird droppings, tree leaves or other unusual particles on the solar panels.
  • The solar panels are ground mounted or a very flat rooftop.
  • Or it is the start of a dry season and you want to make sure your solar energy system to perform to maximum.

B/ How do I know solar panels are producing as expected?

Simple answer is: your installer has told you how much solar energy to expect from the photovoltaic system.

So, with the solar power system monitoring that shows you in the mobile app, you can see if the solar array is producing as expected. 

The solar enthusiasts go further in asking, what is the basis of solar kwh estimate? If installer did not give us the estimate, what can we do? Or, what if my friend’s solar energy system produces more than my system?

  • For home owners, how many kwh your system produce depends on many factors such as your location, solar panel tilt, azimuth direction, how many and types of solar panels you have. Find out more in Suntiki solar panel system sizing tool for various locations in vietnam. (Link TBA)
  • The above is also true for factory or business owner who invest in large scale system. However, here the contract is also often linked to performance guarantee to a certain minimum annual energy production. The contract usually refer this as Performance Ratio (PR) and is usually determined by softwares such as (for example PVSYST). The principle in the softwares usually have to take into account all the above, but now, the number we get can be contractually reliable to ensure business owner get the expected profit from solar.

C/ How to find out how much solar energy the factory use and how much I save?
