What is the life expectancy of a solar panel

Solar panels provide homeowners with a terrific method to lower their carbon footprint. Luckily, the lifespan of solar panels will allow you to create electricity for many years, delivering a significant return on investment.

Photovoltaic (PV) modules often come with 20-year warranties that guarantee that the panels will produce at least 80 percent of the rated power after 20 years of use.

In this article, we’ll explain how long solar panels last, review solar panel degradation rates, and techniques to make sure your solar panels survive as long as feasible.

What is the ‘solar panel degradation rate’?

Over time, solar panels lose their ability to collect sunlight and convert it into solar energy due to variables such as hotter weather and the natural decline in chemical potency within the panel. This is what is referred to as the “degradation rate”.

The lower the deterioration rate, the better the panel. When a solar panel has a reduced deterioration rate, it will produce more energy over its lifetime.

Degradation rates vary from one brand to another; higher-quality panels have a lower degradation rate against lower-quality panels. This is vital to bear in mind when completing a solar panel comparison since it might make more sense, in the long run, to spend more money on higher-quality panels.

Tips to make your solar panels last longer

1- Regularly get your panels checked and maintained

Broken glass, cracked panels, and loose connections are the top three difficulties that you can have with your panels throughout the years.

Electrical defects are more difficult to find, but if you believe something is wrong with your solar system, have the firm examine your power output.

2- Replace inverters after 10 years

Faulty inverters cause system breakdowns considerably more often than the panels themselves. A typical solar inverter has a lifespan of 10-15 years, with 5-10 years of guarantee.

3- Maintain and replace batteries

If you have a large bank of batteries, change them occasionally. This is so that each battery will receive an equal amount of charge, which will extend its service life.

You can also optimize their charging by using large battery cables, which have lower resistance.

4- Keep your panels clear of debris and other materials that may damage it

Although quality solar panels are intended to resist severe winds, heavy snow, and even inch-sized hail dropping at around 50 miles per hour, you still need to maintain them clean at all times.

It’s also always best to wipe them off in the morning before they heat up, so they don’t crack.

5- Work with a trustworthy solar panel provider

Probably one of the finest things you can do to make your solar array last longer is to hire a dependable provider at the very start.

Final Words

Some solar panels can last longer than 30 years, but most panels can be expected to perform at optimum levels up to 25 years. There are two main types of chemistries being used for solar power systems – lead-acid and lithium iron phosphate. Lead-acid batteries can expect a much shorter lifespan than lithium batteries. Heavy use and deep discharging continuously will shorten the life of your battery bank.
