Why Solar

Solar power systems reduce up to 100% your electricity costs, depending on system size. Utility prices are going up every year. Solar power provides you security from rising electricity rates.

A solar electric system adds value to any domestic or commercial building and pays back the investment in few years.

Solar is an environmentally responsible technology. Unlike fossil fuels, it does not emit pollutants which create harm to humans and the environment.

It is a proven technology with panels that are backed by a 25-year manufacturer warranty.


Photovoltaic (PV) or solar cells as they are often called, are semiconductor devices that convert sunlight into direct current (DC) electricity. Groups of PV cells are electrically configured into modules and arrays, which can be used to charge batteries, operate motors, and to power any number of electrical loads. With the appropriate power conversion equipment, PV systems can produce alternating current (AC) compatible with any conventional appliances, and can operate in parallel with, and interconnected to, the utility grid.

A typical silicon PV cell is composed of a thin wafer consisting of an ultra-thin layer of N-type silicon on top of a thicker layer of P-type silicon. An electrical field is created near the top surface of the cell where these two materials are in contact, called the P-N junction. When sunlight strikes the surface of a PV cell, this electrical field provides momentum and direction to light-stimulated electrons, resulting in a flow of current when the solar cell is connected to an electrical load.

Solar Energy In India

With about 300 clear, sunny days in a year, India's theoretical solar power reception, on only its land area, is about 5000 Petawatt-hours per year (PWh/yr) (i.e. 5000 trillion kWh/yr or about 600 TW).The daily average solar energy incident over India varies from 4 to 7 kWh/m2 with about 1500–2000 sunshine hours per year (depending upon location), which is far more than current total energy consumption. For example, assuming the efficiency of PV modules were as low as 10%, this would still be a thousand times greater than the domestic electricity demand projected for 2015.

Solar Energy Today and For the Future

People decide to buy solar power systems for a variety of reasons. Many want to help preserve the earth's finite fossil-fuel resources and reduce pollution. Buying a solar power system is a powerful and direct way for you to help protect the environment, and make a long-lasting commitment to the planet's future.

Others would rather spend their money on an energy-producing improvement to their property than to send their money to a utility or fuel company. Some people like the security of renewable energy, because it makes them less vulnerable to future increase in electricity and fossil fuel prices. Others are interested because renewable energy systems can provide emergency power in case of storms or other power system failures. Finally, some people just don't like paying utility bills and appreciate the independence that renewable energy provides.

All of these are good reasons! Sunwatt India can help you learn more  why many consider solar energy to be the choice for the future. We can also help you decide if a solar hot water or solar electric system makes sense for you.
