The cache is hidden along a quiet country road with some marvelous views and flora close by to the enormous Brandvlei Dam.
Climate change, the soaring global electricity demand, the scarcity of fossil fuels and, consequently, their rising costs, make renewable energy gain in importance. Among green energies, solar and wind energy are the most important energy sources, along with hydro energy. Renewable energy souces are present nearly everywhere and available without long transport. This can help countries lacking natural resources gain greater independence from fossil fuels and secure their own climate-friendly energy supply.
Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material. Materials presently used for photovoltaics include monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium gallium selenide/sulfide. Due to the growing demand for renewable energy sources, the manufacturing of solar cells and photovoltaic arrays has advanced considerably in recent years.
At the cache site is a stand- alone photovoltaic power system powering a wireless communications system. Stand-alone photovoltaic power systems are electrical power systems energized by photovoltaic panels which are independent of the utility grid. In stand-alone photovoltaic power systems, the electrical energy produced by the photovoltaic panels cannot always be used directly. As the demand from the load does not always equal the solar panel capacity, battery banks are generally used. Batteries accumulate excess energy created by a PV system and store it to be used at night or when there is no other energy input.
