1 KWp to 100 KWp ON GRID and OFF GRID solar power plants for residential, commercial and industrial sector.
Advantages of a Grid Connected Solar System
A grid-connected photovoltaic power system will reduce the power bill due to the import and export of power through net metering provision. Illustration: Someone imports (consumes) 1,000 kWh from the grid and exports 600 kWh to the grid in a billing cycle. The energy bill will be for 400 kWh (1000 kWh – 600 kWh) accounted by Net meter.
The reduction in power bill is possible as surplus electricity produced can be sold to the local electricity undertakings.
Grid-connected PV systems do not require batteries. Batteries are costlier and require periodic maintenance and also lead to wastage of 15 – 20 % energy in storage and retrieval.
Grid-connected PV systems are comparatively easier to install as they do not require a battery system and much easier to operate and maintain.
Grid tied solar (PV) power generation systems has the advantage of effective utilization of generated power because there is no storage losses involved.
Segregation of load is not required, as it takes care of the entire load requirement. An on-grid or grid-tied system guarantees that you’ll always have all the electricity you need, even when your solar panels are not producing energy. If your solar PV panels are not keeping up with the amount of energy you are using, your home/ office will automatically pull electricity from the grid. When you choose an off-grid system, the Solar panels will charge a battery from which your home can draw power when the solar energy system can’t keep up, but the amount of electricity available will be necessarily limited by the amount of energy the battery can store. That makes off-grid solar panel systems less reliable during periods of extreme weather or extended periods of cloud cover.
A photovoltaic power system is carbon negative over its lifespan, as any energy produced over and above that to build the panel initially offsets the need for burning fossil fuels. Even though the sun doesn't always shine, any installation gives a reasonably predictable average reduction in carbon consumption.
The Importance of Solar Energy
Solar energy offers clean, climate friendly, abundant and inexhaustible energy resource to mankind. Among the various renewable sources, solar energy potential is the highest in the country. Tamil nadu has reasonably high solar irradiation of 5.5 to 6 KW/m² with around 300 clear sunny days. Southern Tamil nadu is considered to be one of the most suitable regions for development of solar power in the State. The cost of solar energy have been falling and are entering new areas of competitiveness. It is considered important to fully exploit the solar energy, in light of the ever increasing cost of exhaustible fossil fuel. The Government of Tamil nadu has launched the Tamil nadu Solar Energy policy 2012 to promote harnessing of this renewable resource to the maximum extent in order to ease the power situation in the State. It has been envisioned to add about 3000 MW by the year 2015 under this policy.
Industry Growth Prospects
The Industry growth prospects for solar energy sector seem to be favorable in long term as India is a rapidly growing economy which needs energy to meet its growth objectives in a sustainable manner. With depleting reserves of conventional fuels like oil & coal and the need to reduce carbon emission, alternate fuel and renewable energy technologies have been gaining prominence over the years. However, globally, solar energy continues to be costlier compared to conventional sources.
Benign in Nature.
Favorable programs and policies (rebates/tax credits, RPSs/Renewable goals and NM/IC guidelines) are being implemented by the states as well as the federal government.
