Birth of solar
French scientist Edmond Becquerel discovers the photovoltaic effect while experimenting with an electrolytic cell made up of two metal electrodes placed in an electricity-conducting solution—electricity-generation increased when exposed to light. His dream was to cover houses with solar panels to generate power for the household. In 1954 photovoltaic technology is born in the United States when Daryl Chapin, Calvin Fuller, and Gerald Pearson develop the silicon photovoltaic (PV) cell with 6% efficiency at Bell Labs — the first solar cell capable of converting enough of the sun’s energy into power to run everyday electrical equipment.
The electricity solar panels produce is clean, an environmentally friendly way to generate power unlike the use of coal or other fossil fuels.
The average vehicle travels 15000 km per annum, which is equivalent to 4, 5 tons of carbon dioxide emissions annually. A 3,5 kW grid connected solar power system will avoid 4,5 tons of carbon dioxide created through coal fired power generation – so it’s the equivalent of taking a car off the road each year.
Because they have no moving parts solar modules are extremely reliable with an expected life span of several decades. They are also self-cleaning easy to install and require very little in the way of maintenance.
