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.


Solar Power Packs

Our Principles offers customized packaged solution for specific Electrical Energy requirements for domestic and industrial purposes. These systems provide reliable and uninterruptible power for house holds, educational intuitions, rural health centers, shopping complex and industries. These power packs can be used to supply power in critical areas as a power source during power outages or continuously. Sunwatt globally has wide experience in executing very large grid connected PV power plants to various applications.

Our Principles would begin designing and installing solar power packs for industries, residential societies, individual houses, campuses etc. With the latest announcement of Jawaharlal Nehru Solar Mission, the targets for solar installation in India have been raised to unprecedented levels. The subsidies offered by Government are also very high resulting in feasible economic proposition for solar projects. solar power packs are very high on priority with the Indian Government and many KW and MW solar installation are expected to happen very soon. With the latest government announcements, solar power packs have become attractive replacements for Diesel Power Generation sets. Similarly a lot of projects on hybrid systems involving both wind and solar are expected and Our Principleswould want to capture that market too.

In India we are actively participating in the National Solar Mission under Ministry (MNRE) announced by Government of India. We are promoting Green Energy by executing prestigious Government Solar PV projects. We are associated with world leaders like SMA Germany, Emerson to provide world class technology in terms of solar inverters and advanced electronics. For Solar Modules we have associated with M/s. Solar Semiconductor and other leading manufacturers. We use VRLA Gel Batteries incorporating the latest technology suitable for solar applications. All our subassemblies comply to International standards.


Foundation options

We understand that foundations are the most important element of a solar mounting structure, that is why we provide a complete foundation design along with signed and sealed structural drawings. Our engineers design foundations to have an adequate load capacity with limited settlement. We consider all applicable design aspects including, but not limited to, the characteristics of the soil, weight of the structure, live loads, transient load and settlement when designing the foundation for the most economic and robust solar racking structure in the industry.

Foundation type may vary due to soil conditions and penetration restrictions;Our Principles engineers are experienced in working with different foundation types including: Driven Post, Concrete Piers, Spread Footings, Helical/screw type anchors and Floating Ballast


Ground Mount Solar:

Our Principles ground mount solar systems are designed and engineered for each customer's site specific conditions to minimize the field installation labor and require no field welding, drilling or other on-site fabrication. We provides a wide range of PV mounting system sizes to offer freedom and flexibility to support every type of PV module.  ground mount solar system is a perfect utility scale solar racking solution.


Floor Mount Solar:

Solar non-penetrating roof mount systems are cost effective to install and are made of durable, long lasting materials. Our roof mount system is flexible to mount any type of module and is easily disassembled to allow access to the roof.


Specialty Structures

If ground space is tight and the roof is not an option, we offer PV mounting solutions for areas such as walkways, detention basins etc., that can optimize energy output while maintaining an architectural aesthetic for high end facilities.




SPV Modules conform to international Standards and specifications Mono/Multi Crystalline

A solar module is a device which is used to convert energy contained within the sun’s rays into electricity. A photovoltaic module is an interconnected collection of photovoltaic cells combined to form a solar module.

When a number of solar or photovoltaic modules are installed together, this is commonly referred to as a solar array, or photovoltaic array.

The Solar Semiconductor’s family of multi crystalline PV modules offers models ranging from 135 to 270 W. These modules employ 156 mm cells and are designed for grid connects as well as off-grid applications.

Other custom modules may also be configured. The 156 mm multi crystalline cells lay embedded in transparent EVA, behind tempered glass. The glass is inset deep in the frame thereby ensuring maximum protection.

The back of the module is sealed with a high-quality back sheet. The junction box has no hollow cavities, is water tight, and is resistant to temperature and UV radiation. At Solar Semiconductor, quality is not an afterthought; it is designed into our modules and is ensured by automated production with minimal manual intervention. Each and every module is thoroughly tested for performance.

We are backed by dedicated team of Engineers who are capable of providing relentless service support and system solution to your requirement at any time round the clock. Our Team Is Our Strength!
