A solar panel typically lasts approximately 30 years. During that time, most systems require little to no maintenance beyond removing leaves or snow and hosing off debris. In general, the life of solar panels depends on the quality of the solar panel technology used, including the photovoltaics (PV), and the quality of the overall installation.
Annually, solar panels lose close to half a percent in overall performance. After 25 years of operation, high-quality solar panels will still be operating at almost 90 percent efficiency. The modules we install on homes and businesses are efficient, lightweight and aesthetically pleasing. More importantly, they're cost effective and extremely efficient. With wiring, mounted panels are flushed to the roof.
Other components protected by premium trim may have a longer lifespan. While all solar systems operate at reduced efficiency over time, well-maintained conditions and optimal climates may help your solar panel system continue operating for years longer. Solar panels can actually protect your roof from the damaging effects of weather.
Homeowners are often surprised at how low-maintenance a solar panel system is. But even so, we leave nothing to chance when it comes to how long solar panels last. All SolarCity systems come with a 20-year protection plan that includes 24/7 lifetime monitoring. Should repairs be necessary, our highly-trained team of technicians will address the problem as quickly as possible.
Solar power is the reliable, safe and eco-friendly alternative to energy sourced from coal and gas. If you've always wanted to draw your electricity from a clean renewable source but were wary of the costs associated with solar and the challenges of installation, this is the time to take another look at solar energy. The price of solar panels is lower than ever and federal tax credits may cover 30 percent of the cost of a solar system. Whether you are considering leasing a solar system or buying a system outright, our energy advisors can take you from financing all the way through design and installation.
Because every structure and household is different, how much money you save using solar power with SolarCity will depend on the size of your system and your average electricity usage. However, you will start saving money on electricity from the moment your solar panel system is switched on. While most SolarCity systems require little to no maintenance over the lifetime of the panels, our custom solar system monitoring solution works 24/7 to ensure that we are notified of problems immediately so we can take care of any repairs quickly.
