Provided by the manufacturer.
Available from manufacturer
Both the batteries and charge controllers have a 5 years lifecycle, whereas the PV solar panels have a 25 years lifecycle.
Manufacturer Specified Performance Parameters
The manufacturers specify a high load bearing capacity capable of resisting high wind forces and snow load due to special acrylic foam tape used to fix the frame, guaranteed electrical performance as cell strings are produced through automated soldering technology under uniform pressure and thermal process, and highest personal safety and module robustness as Hi-Pot tester carries out hi-potential and ground continuity test for individual panel as their performance targets.
Vetted Performance Status
If pressure is applied on the photovoltaic panel by sitting or stepping on it, the device might break and cause bodily injury or electrical shock. Precaution must be taken regarding electrical contacts or wiring, the person handling them must use adequate safety gear. To avoid electrical shock, the photovoltaic panel must be earth grounded. A minor risk of burns exists due to the heating of the photovoltaic panel's surface by the sun.
Complementary Technical Systems
Depending on the capacity of the system, appliances such as a TV, Radio or DC fan can be added.
