Safety

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.
