A solar energy system creates usable power from sunshine. There are two basic kinds of systems:
1.Photovoltaic or PV uses sunlight to generate electricity. It’s the same technology found on pocket calculators, just on a larger scale. PV systems can be designed to generate the majority of the electricity used in your home, or just a portion of it.

2.Thermal solar uses sunlight to heat water.Typically this is used for a home’s hot-water supply.A well-designed thermal system can be extremely effective,and provide most of the hot water used in your home.

Solar systems work even when it’s cloudy. Naturally, cloud cover reduces the amount of solar radiation reaching the panels, but the system will produce some electricity and/or heat on all but the most overcast days.

Fossil fuels are a leading cause of global warming and air pollution. Solar energy reduces the amount of fossil fuel that is burned, thus reducing the pollutants and CO² that get into the atmosphere.BHEL solar energy systems have the added benefits of very high efficiency, durability, and service life – they’re engineered for sustainability. This means fewer replacements and repairs, saving even more energy and precious resources.

In many ways:
• It reduces your energy bill, and in many areas the utility will buy back any extra electricity you generate. 
• It adds to the value of your home.
• You gain energy independence.
• Perhaps most importantly,it’s a good investment in a sustainable future for yourself and your loved ones.

Currently, the US depends on fossil fuels, especially oil, from potentially unstable or unfriendly countries. These supplies are vulnerable to political upheaval, trade disputes, embargoes, and other disruptions.
Solar energy can help reduce this dependency, making our economy, our nation, and your family more secure.

Right now the US has to import oil and natural gas to cover our energy needs. The cost adds up to many billions of dollars, and all of that money leaves the country. But solar energy is generated locally. The energy dollars stay at home, creating economic growth and benefiting your community.

This technology is called “photovoltaic” or PV. Sunlight hitting silicon cells in a module generates a DC current. This current goes to an inverter in the house, which turns it into household AC. Grid-connected systems are linked to the regular electrical grid, and reduce the amount of current the house draws from the power company. Off-grid PV systems are completely independent of the power company. They require extensive battery backup and are more complex to install and run.

That depends on the kind of system you have. PV systems with battery back-up will provide electricity if the power goes out.

A properly installed solar panel cannot give you a shock, and our mounting system keeps wires safely bundled and out of the way. An improperly installed or damaged module can give a shock.

Fluid running through a solar collector is heated by sunlight hitting the collector. This heated fluid circulates through a storage tank, where it transfers its heat to the water in the tank. The storage tank is part of the regular water supply and is installed upstream of the conventional water heater. The solar fluid never touches the water.

The pump that circulates the solar fluid runs off electricity, so in a power outage it won’t operate, unless you have a standalone system with battery backup.

Yes. The technology has made huge strides since then. For example, our solar collectors use propylene glycol instead of water. Propylene glycol is a more efficient heat transfer agent, it doesn’t freeze, and algae won’t grow in it. It is safe and nontoxic. And of course, the collectors look great on your roof.

Anybody who has a good site can benefit from a solar energy system. Once you get it installed, the power is free. And solar isn’t just for the sunny south – solar works in all areas with sunlight.BHEL systems are in use around the world, and we have long experience with all kinds of weather extremes. Our systems work efficiently in pretty much any climate.

Direct sunlight is the most important factor. For most people that means mounting the system on the roof, so we’ve devoted much time and effort to creating the best rooftop mounting system in the industry. It fits on shingle or pitched roofs and has many engineering features that make it intrinsically sturdy.

PV systems are inherently very low-maintenance, requiring the system owner only to wash the solar modules down with water when they get dirty so light can get through, and our special mounting hardware greatly reduces the need for periodic bolt-tightening. Conventional thermal solar systems require regular venting, but our third generation solar thermal systems don’t even need that. The circulation pump and valves are mechanical, so they will need replacing eventually, but here again, our systems are self lubricating so the service intervals are longer than with our competitors.

Our modules and collectors have tempered safety glass set deep into heavy-duty frames, and our mounting system is extraordinarily robust. If properly installed, our systems are at least as strong as the roof they are mounted on, if not stronger.

It is impossible to give a simple answer, since this depends on system capacity, home layout, and other variables. Certainly the cost has gone down dramatically in recent years, and now there are many tax breaks, electricity buy-back programs, and incentives.

Because you’ll lower your utility bills, gain energy independence, and help create a better environment and a better future. It’s easy to do, easy to live with, and it pays for itself.

Let’s build sustainability and turn your home into a producer of clean, renewable solar energy. You’ll become part of the solution to global warming. You’ll also gain independence from rising energy costs.
