With the help of light or heat, the sun radiates energy. People have been using this
energy for many centuries and it is one of many types that is known as a fuel for
renewable energy. Photovoltaic (PV) is the field of exploration and preamble of new
technologies and impersonations to switch sunlight into a more usable form:
electricity. In recent years, the production of photovoltaic cells has significantly
increased, almost reduplication every two years since 2002, making it the swiftly
growing energy source in the universe. This enhancement in occurrence and
consumer demand growth has led to a worldwide interest in developing new steering
for photovoltaic technology.
Bangladesh is one of the most deeply replenished countries, with 79 percent of the
demography living in rustic bounds .In 1997, the realm's annual energy expenditure
per capita was about 77 kg, to advantage beneath the worldwide genuflection of 1474
kg (ADB, 2001). Just about 30 percent of the demography has perception to
electricity (BPDB, 2002)[7]. More than 80% of populace lean on trite sources of
energy such as firewood, cow dung, and agricultural relics for their energy needs.
Superfluous use of firewood is a hazard to the remaining arbor cover, which is only
10% of the total land area (WEC, 2000)[8]. Bangladesh has grandiose provisions for
renewable energy, such as solar insulation and biomass. Using these resources seems
to be a promising way of improving the attribute of life of rustic villagers. Solar
power is not newish in Bangladesh, as since 1996 companies have been trying to
market solar energy systems to the overt. Hereto the idea took a lingering time to go
in a technologically behindhand bourn like Bangladesh. A number of secular solar
energy systems are being used in homes across the bourn in Bangladesh. In this scale,
the use of solar energy is highly brawny and salutary as more than 60% of the bourn's
areas do not have access to main grid electricity. As part of the rustic Electrification
and Renewable Energy Development Project (REREDP)[9], which subsidizes solar
energy systems, the World Bank supports a program to make solar energy available to
the comprehensive demography in Bangladesh. |
