Recommendations About Solar Energy:
One of the biggest advantages of employing solar energy is the huge reduction of greenhouse gases that would otherwise be released into the atmosphere on a daily basis. As people begin switching to solar energy, the environment will certainly benefit as a result. Of course, the personal benefit of using solar energy is that it will reduce the monthly energy costs for those who use it in their homes. Homeowners can ease into this form of energy gradually and let their level of participation grow as their budget allows and their solar knowledge grows. Any excess energy that is produced will actually warrant a payment from the power company for a change. Installing a solar (photovoltaic or PV) power system is a great way of capturing the sun's energy to generate electricity at home.
Increasingly affordable option to reduce your power bills.
Generate your own clean electricity.
Low-maintenance once installed and may increase the value of your home.
Solar energy is environmentally friendly as it has zero emissions while generating electricity or heat.
Examines burdens, effects, and damages associated with electricity generation from coal, natural gas, nuclear power, wind, solar energy, and biomass. In the cases of fossil fuels (coal and natural gas) and nuclear power, the analysis includes externalities associated with upstream activities, exploration, fuel extraction and processing, and the transportation of fuel to generating facilities, as well as damages associated with downstream activities of electricity generation and distribution.

Electricity from Solar Energy:
India is endowed with vast solar energy potential. About 5,000 trillion kWh per year energy is incident over India’s land area with most parts receiving 4-7 kWh per sq. m per day. Hence both technology routes for conversion of solar radiation into heat and electricity, namely, solar thermal and solar photovoltaics, can effectively be harnessed providing huge scalability for solar in India. Solar also provides the ability to generate power on a distributed basis and enables rapid capacity addition with short lead times. Off-grid decentralized and low-temperature applications will be advantageous from a rural electrification perspective and meeting other energy needs for power and heating and cooling in both rural and urban areas. The constraint on scalability will be the availability of space, since in all current applications, solar power is space intensive. In addition, without effective storage, solar power is characterized by a high degree of variability. In India, this would be particularly true in the monsoon season.
with considerable local variability from north to south and regionally as a result of sun angles and weather patterns. At present, most solar panels are installed on building roofs or immediately adjacent to buildings to provide electricity on site. When a site’s electricity use exceeds solar energy availability, electricity is supplied from the grid (or from batteries, if electricity demand is low). In this case, solar panels reduce grid-based electricity demand at the end use, thus becoming similar to an energy efficiency improvement. Some solar panel installations also can feed excess electricity back into the grid during periods of peak solar or low local on-site demand periods.
Energy from the sun can be captured in two ways: as heat energy (thermal energy) or as light energy. Photovoltaic (PV) technology, also known as solar panels, converts the sun's light energy into an electrical current.
Solar power systems have become very popular with every home owners soon:
While the upfront cost of a solar power system must be met, once installed they require little maintenance, can be expected to last 25 years or more, and the electricity they generate is free. The cost of solar panels is coming down quickly and systems are becoming more affordable for many households.
The National Solar Mission is a major initiative of the Government of India and State Governments to promote ecologically sustainable growth while addressing India’s energy security challenge. It will also constitute a major contribution by India to the global effort to meet the challenges of climate change.
The National Action Plan on Climate Change also points out: “India is a tropical country, where sunshine is available for longer hours per day and in great intensity. Solar energy, therefore, has great potential as future energy source. It also has the advantage of permitting the decentralized distribution of energy, thereby empowering people at the grassroots level”. Based on this vision a National Solar Mission is being launched under the brand name “Solar India”.
From an energy security perspective, solar is the most secure of all sources, since it is abundantly available. Theoretically, a small fraction of the total incident solar energy (if captured effectively) can meet the entire country’s power requirements. It is also clear that given the large proportion of poor and energy un-served population in the country, every effort needs to be made to exploit the relatively abundant sources of energy available to the country. While, today, domestic coal based power generation is the cheapest electricity source, future scenarios suggest that this could well change. Already, faced with crippling electricity shortages, price of electricity traded internally, touched Rs 7 per unit for base loads and around Rs 8.50 per unit during peak periods. The situation will also change, as the country moves towards imported coal to meet its energy demand. The price of power will have to factor in the availability of coal in international markets and the cost of developing import infrastructure. It is also evident that as the cost of environmental degradation is factored into the mining of coal, as it must, the price of this raw material will increase. In the situation of energy shortages, the country is increasing the use of diesel-based electricity, which is both expensive – costs as high as Rs 15 per unit - and polluting. It is in this situation the solar imperative is both urgent and feasible to enable the country to meet long-term energy needs.
The objective of the National Solar Mission is to establish India as a global leader in solar energy, by creating the policy conditions for its diffusion across the country as quickly as possible.
