How many percent of the solar panels price is lost after 25 years?
The percentage of the cost of solar panels that is lost after 25 years will depend on a number of factors, including the quality and efficiency of your panels, the amount of maintenance that they receive, and the overall cost of your installation.
In general, however, most solar panels are designed to last for 25 years or more, and the vast majority of panels will still be producing electricity at or near their rated capacity after this period of time. In fact, many solar panels are designed to maintain 80% or more of their rated power output even after 25 years of use.
Therefore, while some of the cost of your solar panels may be lost over time due to factors such as depreciation and maintenance, the majority of the cost will be offset by the electricity that your panels continue to generate over their lifespan. By investing in high-quality panels and maintaining them properly, you can help to ensure that your solar panels continue to generate electricity efficiently and cost-effectively for many years to come.
