Solar panels pay for themselves in six years, study shows
A report published by the Energy&Climate Intelligence Unit of the United States concludes that the payback time for solar panels is six years. Taking into account that the useful life of this self-consumption element is 25 years, it assumes that the remaining 19 years are of benefit.
The study points to solar panels as one of the best energy alternatives of the moment, especially given the increase in the price of electricity as a result of the current crisis.
Solar panels pay off in six years
The report takes as a reference solar self-consumption installations in operation in the United States, but the results could be extrapolated to other countries, including Europe.
According to the conclusions published by the researchers, the best option is solar panels combined with storage systems, as these allow the energy that is not consumed to be stored for use in times of shortage (on cloudy days or at night).

The study confirms that, at present, the use of solar panels is cheaper than gas and anticipates that this price difference will increase in the coming years, which will also reduce the payback time.
