Why harness solar energy is important?

Using a great range of evolving technologies,solar energy was always harnessed by humans since ancient times.Solar energy is considerent a renewable source of energy along with wind,wave power and biomass.But i guess the amount of solar enery used is very less nowadays.

Heat engines and photovltaics are responsible for the solar generation.There are many other things also which can be used from solar energy.Some of the solar applications include cooling through prtable water vis distillation,disinfection,solar cooking and solar hot water.Now considering that the use of solar energy is so important,we need to harness it which can be very easily done by solar panels.
Solar technologies are also broadly classified into two categories of active solar and passive solar depending uopn the way they capture,distribute and convert solar energy.Active solar techniques use photovoltaic panels to harness the energy and passive techniques use way of orienting a building to the sun side and designing the sapces in such a manner so that they circulate air.
One of the companies which actually does the whole designing, construction and management of solar energy solutions is PEG based in New Jersey.The whole solar power financing is also done by the company itself.
