The lifespan of solar power generators is approximately 25-30 years. However, this doesn't mean they stop producing electricity after 25 years. It means they won't operate at full capacity and their efficiency will decrease. Solar power generators will work for many decades if they are not affected by wind, debris, air pollution, and other external factors. Solar panel degradation rate averages 0.8% per year. This 0.8% degradation rate means that in the second year, the solar generator will operate at 99.2% of its original output. Continuing this way, after 25 years it will continue operating at 82.5%. However, depending on which brand of solar generator you purchase, degradation rates vary. Choosing a solar generator with a lower degradation rate is beneficial over many years. If the solar generator is producing enough energy for your electricity needs, there's no rush to replace it.

Additionally, the equipment that makes up the system such as mounting racks, batteries, and inverters are more likely to degrade than solar panels. Mounting racks are drilled into the roof to hold solar panels, so they wear out from sun, rain, snow, and excessive heat. Inverters have continuous operation converting direct current into alternating current for use in your home, so they need to be replaced during 10-15 years of use.

Although solar generators require minimal maintenance and very little servicing, it's important to periodically check your solar system and monitor its performance. Here are recommendations for checking whether your solar generator is operating at full capacity.

  1. Protect your solar generator from debris and other damaging factors

Dust, air pollution, leaves, bird droppings, excessive heat, and excessive cold affect solar generator efficiency. Summer rain cleans solar panels, but if they're not operating at full capacity, you should contact a professional to clean them with special equipment. Install solar panels considering trees and buildings that may shade them.

  1. Install additional equipment to regularly monitor and check if the solar generator is working

Regular performance monitoring helps operate your solar system's performance, meter, inverter, and other components most efficiently. You can also regularly monitor changes in your electricity bill and energy consumption.

  1. Find a reliable solar energy supplier

The first step you can take to keep your solar system running for a long time is to work with a quality solar system installer. Although solar energy systems require little regular maintenance, you need to choose official suppliers who offer comprehensive maintenance packages during the product's lifespan to continue producing clean, affordable, reliable energy efficiently for many years.
