The Tregoo solar panels are designed to resist atmospheric agents in conditions of normal usage. Examples of atmospheric agents are: high temperatures, sand, salt water, vibrations and rain.

Hippy solar panels have been designed also to be used during outdoor activities, such as trekking, mountaineering, kayaking etc. They are waterproof and don’t fear salt and fresh water.

The Lithium-Ion technology is totally different from the one used in traditional lead-acid batteries. Lithium-Ion batteries are lighter and benefit from a higher capacity.

The basic unit of panel is the photovoltaic cell that converts light directly into energy. It is made ​​of silicon and is doped with phosphorus and nitrogen to free electrons. The electrons hit by photons are sent to the next cell. This procedure is repeated for the number of cells having a number of electrons in the output.

The average lifetime of a solar panel depends on various factors, for example, the periodic maintenance and the build quality. The Tregoo solar panels are made by following thorough quality standards.
