Advantages of Solar Water Heating System
It is economical. A single collector system provides an equivalent of 5 KWH to 6 KWH of heat replacement on an average.
Potential of Solar Water Heaters in India
Solar thermal technologies hold significant promise for India with high solar insulation of 4 – 6.5 kWh/ sq.m /day for an average of 280 sunny days. Solar water heating system is a commercially viable and technologically mature product which has existed in the country for many years. Yet, against a technical potential of 45 million sq. km. of collector area only a little over 2.5 million sq. km of collector area has been installed. This works out to a little more than 2 sq.m./1000 people as against countries like Israel and Cyprus, which have over 500 sq.m./1000 people.
The primary use of copper in wind energy technologies is in the coil windings in the stator and rotor portions of the generator, in the high-voltage power cable conductors, transformer coils and earthing.
Copper forms part of the materials presently used for photovoltaic solar cells, in the technology’s cabling, earthing, inverter, transformers and photovoltaic cell ribbons.
