Solar technology is based on the
‘Photoelectric Effect’ for which Albert Einstein got the Nobel Prize in 1905. Unlike
fossil fuel solar energy is not going to run out, at least, not in the next 15
billion years. Most importantly, it is the cleanest form of energy which is pollution
and noise free.
In the last few decades solar
system efficiency increased to 30%, solar panel cost decreased to $3 per watt.
With these significant improvements over time, solar technology is not confined
in non-commercial installations anymore. It is now found on artificial
satellites, UAV, cars, green houses and corporate buildings.
world has a large area of roads and concrete surfaces exposed to Sun.
Scientists are planning to pave roads with solar modules. If the project succeed the
be able to generate electricity.
Like the rest of the world solar
technology is also very popular in Bangladesh. People in Bangladesh use solar panels mainly to generate
electricity and to cook food. Even though the government has taken an
unthoughtful proposal of imposing 15% VAT on solar panels the country has installed
the largest number of ‘Solar Home systems’. Nevertheless Bangladesh still has
so much to improve. There is no solar panel fabrication facility in the country.
Users are to import panels at a higher price which is not affordable for
everyone. It is necessary to do more research on solar technology in the
universities. The scientists and researchers may show their potentials if they
get the funding.
