What is the life of a solar panel

Solar panel systems survive a long period depending on the amount of active use, the amount of sunshine converted into power by the solar panels and the atmosphere of the area. Most systems are only in use for 6 to 8 hours per day.

Manufacturers will normally issue an industry-standard 25 to 30-year warranty for the output performance of the solar panels and a 5 to the 15-year warranty on the panels’ workmanship. Balance of system components like inverters and mounts have manufacturer product warranties from 10 to 25 years. Solar panel systems have been reported to work for 30 to 40 years.

The projected lifespan of a solar power installation.

Most online calculators that are used to calculate solar savings and returns base their results on a 25-year system life, but In reality, high-quality panels could still produce output (at a gradually reducing capacity) beyond the 25 year period, while cheap panels are unlikely to reach the 25-year mark and still be performing adequately, and may have failed long before.

Cheap panels, with poorer quality silicon cells, less UV stabilized backing sheets, cheaper sealants and framing might deteriorate more rapidly. When solar panels are exposed to the elements (wind, sun, and varying temperatures), they will deteriorate over time and produce less electricity.

Generally, cheaper panels deteriorate faster, often at double or treble the rate of premium quality modules.

Lifespan for monocrystalline solar panels

Monocrystalline solar panels can endure 25 to more than 50 years, thanks to the fact that they are built of one crystal, decreasing potential failure spots.

Lifespan for polycrystalline solar panels

Polycrystalline solar panels can last up to 25 years, after which the efficiency can diminish as electrical forces cause their crystals to split.

Lifespan for thin-film solar panels

Thin-film solar panels last anywhere from 10 to 20 years, although they can pay off faster than their silicon counterparts.

What can we do to extend the average lifespan of solar panels?

Going solar is a huge investment, therefore you are certainly thinking about how to extend the solar panels’ lifespan. Here are some actions you can do to achieve the best return:

1- Conduct regular inspections

Regular inspections can discover early warning signals with your solar panels, so you can get problems corrected and increase the solar panel’s lifespan.

2- Install a backup battery

Solar panels generally carry significant electrical loads, which can cause stress on your panels over time. A solar battery can ease some of this while offering you a reserve of energy to draw from when the sun is down.

3- Clean your panels

Bird droppings can cause corrosion, limiting overall solar panel longevity. Debris can serve as a great nesting location for pests, who can harm the panels. Cleaning your solar panels periodically can assist to remove both possible hazards while enhancing their overall performance.

Final Words

Solar energy is a long-term investment that pays back over time through savings on electricity bills, and through tax incentives for businesses. There will be an initial pay-back period where the savings made will go towards paying back the cost of the system over a number of years, followed by a longer period of financial return.
