5. Renewable Electricity Technologies …. Cont’d• Solar Electricity- Electricity from solar energy may be obtained through (i) Solarthermal process and (ii) Solar Photovoltaic (PV)- Electricity from solar thermal processes is similar to that inbioelectricity using the Rankine cycle.- Solar photovoltaics refers to the direct and silent conversion of solarenergy into electricity, usually DC form, using a solar cell.- Solar cells may be made from (i) Polycrystalline silicon (ii) singlesilicon (iii) amorphous silicon or (iv) thin film silicon- A solar cell can have an output of about 0.5V, 3.5 amp dc andefficiency of up to 16%.- A solar module or panel consist of many solar cells, suitablyarranged, to give an output of greater than 12V and 3.5-7 ampsat 1kW/m² solar intensity.Prof. A.

5. Renewable Electricity Technologies ….. Cont’d- Modules can last up to 25 years.- A solar array consists of many modules connectedtogether.- Thus a solar PV generator is made up of:- Solar cells- Solar modules- Solar arraysProf. A. S. Sambo21
