Solarform and Juli New Energy announced that they are now providing a linear performance guarantee for Juli photovoltaic (PV) solar modules over 25 years.
The upgraded performance warranty guarantees a minimum of 97% actual power module output of the labeled power rating during the first year of operation. The output is warranted to decline by no more than 0.7% per year, with actual power output no less than 80% of the module’s labeled power rating by the end of year 25.
