Solar Photovoltaic Technology Basics | Department of Energy
What is photovoltaic (PV) technology and how does it work? PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs.
power supply
At 2 hours per day you need 7000/2 = 3500 Watts of solar panels. A PV panel will give ABOUT 200 Watts per square meter of panel in full sun so you need 3500/200 ~= 18 square metres of panels. That''s 2m x 9m or about 6''6" x 30 feet. A VERY large solar array. Packing that up into a mobile unit would be interesting.
