If you are looking at installing solar panels then you might be wondering how long the solar cells are going to last. When looking at solar panels like the ones offered at Green Street Solar you do have to consider this because you do not want to be faced with the expense of having to replace them very often. Of course, you should also consider what options you have available to increase the lifespan of the solar cells.
The lifespan of solar panels will relate to how new they are. Newer models have an average life expectancy of 40 to 50 years when they are properly maintained. Most manufacturers will also offer a warranty that covers half the expected lifespan of the panels. residential financing here
The warranty that you get with the panels will generally cover the performance level of the panels for the first 25 years of their life. The warranty will generally state that the performance of the panels will not drop below 80% during this time. There are many panels that are known to still work at above 80% when they reach the end of their lifespan.
If the correct care is taken with the panels it is possible that they could last for longer than 40 years. However, the performance will decrease over time and this needs to be considered. The 40 to 50-year lifespan relates to both polycrystalline and monocrystalline panels. If you are looking at thin film panels then less is known about the lifespan, but as they come with a 25-year warranty it is expected that they have a similar lifespan.
Extending The Life Of The Panels
Solar panels have been made to be durable as they have to withstand the harsh and unpredictable weather. Generally, there is little maintenance or repairs which need to be completed to keep them functioning. To extend their lifespan you will need to keep them in good condition so that they can continue to function correctly.
It is recommended that you complete regular checks of the panel output from the inverter or the monitoring system that you have installed. If the output is less than what you are expecting you can look to see if there is a reason for this. Repairing the root cause will bring the panels back to optimal functioning and will extend their life.
The best way to increase the life expectancy of the panels is to have them correctly installed. If you are not installing the panels yourself then you need to hire an accredited contractor. If you are going to install them yourself then you should have an accredited provider double check the work to ensure that they have been set up correctly.
The inverter that you use will also play a role in the lifespan of your panels. The traditional string inverters will have a shorter lifespan than the panels at 10 to 15 years. If the inverter is reaching the end of its lifespan then you may not be getting the most from your panels and this could have an impact on the health of the panels.
