How often do you have to replace PV solar panels in Hawaii?

What happens when solar panels degrade?

 

When solar PV panels degrade, their performance declines and they produce less electricity. The rate at which they degrade depends on a number of factors, including the type of material they are made of, the environment they are exposed to, and the amount of sunlight they receive.
 
The most common cause of degradation is exposure to sunlight and heat, which can cause the material to degrade over time. Other causes of degradation include exposure to weather, chemicals, and physical stress.
 

How often should you replace PV panels in Hawaii’s environment?

 

With Hawaii’s weather in mind, the question of how often to replace solar panels is a complex one, as it depends on a number of factors.

 

First, the type of solar panel will affect how often it needs to be replaced. There are three main types of PV panels: monocrystalline, polycrystalline, and thin film. Monocrystalline panels are the most efficient, but also the most expensive. Polycrystalline panels are less efficient, but also less expensive. Thin film panels are the least efficient, but also the least expensive.

 

The most common reason for replacing solar PV panels is due to damage from severe weather. Other reasons for replacement include damage from birds or other animals, physical damage, and manufacturing defects.

 

Additionally, the amount of sunlight that the panel is exposed to will also affect its lifespan; panels in sunny locations will degrade more quickly than those in shaded areas.

 

Finally, the quality of the panel will also play a role in how often it needs to be replaced; panels from reputable manufacturers will typically last longer than those from less well-known brands. 

 

When would I know when it’s time to replace them?

 

PV panels typically have a life expectancy of 25-30 years. It’s necessary to first assess the current condition of the panels and determine if they are still functional.

 

If the panels are still functional, then it may be possible to simply clean them and make sure that they are properly aligned. However, if the panels are not functional, then it will be necessary to replace them.
