FAQ

Frequently Asked Questions(FAQ)


Q: What is solar energy?

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.


Q: Does solar work only on sunny days?

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.


Q: How does solar help the environment?

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.


Q: How does a solar energy system benefit me personally?

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.


Q: How can solar improve national security?

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.


Q: How can solar help the economy?

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.


Q: How does solar electricity work?

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.

Q: Will a solar PV system give me electricity if there’s a power outage?

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


Q: Can a PV system give a dangerous shock?

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.

Q: How do solar thermal systems work?

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.


Q: Will a solar thermal system give me hot water if there’s a power outage?

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.

Q: I’ve seen houses with old solar collectors that are full of unsightly algae. Can that be avoided?

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.


Q: Is solar power for everybody? What if I live up north?

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.

Q: What’s the best place to mount solar panels?

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.

Q: What regular maintenance do I need to do?

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.

Q: Are solar energy systems vulnerable to weather?

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.


Q: How much does a solar energy system cost?

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.

Q:So Why Go Solar?

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.
