JOHANNESBURG - The sun burns 637million tons of hydrogen atoms into 632million tons of helium and thus creates 38460septillion watts (3.846 x 1026W) of energy per second, which equates to roughly 1386 watts per square metre (W/m²) in the upper atmosphere of Earth or 1000 W/m² at sea level on a clear day.
Although solar roof tiles and other solar modules integrated into buildings have been on the market for some time, the concept of an entire solar roof is new. The full roof coverage approach involves a solution where photovoltaics do not represent just an addition to an existing roof surface, but instead it is integrated into the structure of the house for aesthetic, constructive and electrical purposes.
