The Performance Ratio refers to the ratio between the useful and the ideal yield of a photovoltaic system, and it thus defines the ratio between the actual yield and the energy yield that would theoretically be possible under standard test conditions. Depending on the quality of the system, a performance ratio between 70% and 85% is reasonable. A very good system will deliver even higher values. 

The Solar Frontier PowerModules were developed with full consideration for health and environmental protection. The organization for New Energies and Industrial Development (NEDO) in Japan, the Centre for Solar Energy and Hydrogen Research (ZSW) in Germany and the Brookhaven National Laboratory (BNL) in the USA have reported that in the event of a fire only very small quantities of toxic gases are released into the atmosphere. Therefore, Solar Frontier modules do not represent an increased health risk in the event of fire.

Our modules have also been classified in Class E according to EN-ISO 11925-2 by a renowned test institution.
