We would all like cheaper electricity and gas bills. Most of us shop around for the provider with the lowest electricity, gas or oil prices and leave it at that, but there are other ways to warm your house. Not only could you save money in the long term by reducing your household fuel bills, but you can also do so in a more environmentally friendly way and, in today’s world of global warming which produces extreme weather conditions, that is a major factor for many people.

Solar heating can reduce your electricity bills no matter where you live. Obviously, where you live will determine how much sunshine you will get in an average day, but even on a cloudy day with the sun low on the horizon you can still benefit. If you live in a warm climate and don’t need heating for much of the year, you still may wish to heat the swimming pool.

What Equipment Do I Need?

A typical system uses collectors, also called heating panels. These are generally mounted on a south facing roof which should ideally be pitched at an angel of between 30 and 60 degrees. If your roof isn’t pitched, the panels can be mounted at an angel. The size of the panels will depend on the size of the household and your local climate. As a general rule, you’ll need 2.75 sq.m. to heat water for two people, or 4.12 sq.m. for a family of three or four people.

There are two types of panels and the right one for you will depend on your local climate.

• Flat Plate Collectors - a simple flat plate of specially coated black metal covered by glass or plastic. Water passes through pipes that are solered to the plate and the warmed water is then fed to your boiler.
• Evacuated tubes - which are fitted into insulated steel casings. These are more suited to cooler, cloudier climates. By reducing the heat loss, the water temperature can reach 60F/15C so it may not require further heating. Evacuated tubes are more expensive than flat plate collectors.

Can I Install A System Myself?

It is possible to install a system yourself if you are reaonably good at DIY. Either find a parts supplier who will also do the design for you, or join a solar club - non-profit making groups who run one-day courses designed to make solar heating cheaper and easier to install.

How Much Money Will I Save?

Impossible to quantify as it will depend on your local climate, house insulation, heating system, and the type of panels you install. But if you want lower electricity and heating bills, and wish to help the environment by burning less fossil fuel, solar heating is well worth investigating.

For many people, buying something new makes little sense if they can get something refurbished for far cheaper. Refurbished solar panels tend to work the same way, but they can cost you in the end unless you understand the situation.

Refurbished Solar Panels For Your Home

Some families would love to try running their households on solar energy, but might not be able to afford the large price tag. Outfitting your home with solar panels can run into thousands of dollars, and that doesn’t include all of the equipment and adapters you need to use solar energy to its fullest. Refurbished solar panels can be a great way to defray the cost of using solar energy, and can also add to the green aspect of using solar energy, as you are not just harnessing the sun’s energy, you re recycling as well.

Refurbished solar panels are sold by many different online and offline retailers. Whether you choose to buy refurbished components from large businesses or surplus items, resellers are able to obtain the solar panels and then sell them to you. You also have the choice of buying broken or partially working solar panels, for those people who would rather build their own solar panels cell by cell. There are even online bidding sites that offer a place for hobbyists and home owners to sell their refurbished solar panels, and other resources such as newspapers often yield ads for refurbished solar energy products.

There are a few things that you should keep in mind when shopping for refurbished solar panels. Older panels will most likely be the cheapest; because newer solar panels are smaller and take up less space. People buying refurbished panels will pay more for the newer models. Therefore, you’ll get the most wattage per dollar by buying the older refurbished solar panels. Some solar panels that are listed as broken may only need simple repairs, such as soldering. Cracked glass or condensation under the glass of solar panels, however, means that the panel will not work and it is probably not worth your time to repair it. Even solar panels that are over 20 years old can still be going strong, so you can take a chance on buying much older solar panels if they appear to be in good condition.

Buying refurbished solar panels, however, comes with a major financial catch. There are massive tax incentives to going solar these days. When I say massive, I mean massive. Various government entities offer thousands of dollars in tax credits and discounts. It is almost universally required that the systems must be purchased new for you to claim these benefits. If you purchase refurbished solar panels, you will miss out. Make sure to calculate the savings of buying refurbished panels versus new before making your decision.

Choosing solar energy is a step that benefits not only your household, but the whole world. When buying refurbished solar panels, you are also helping to recycle what might otherwise end up in a landfill. Given the financial benefits of buying new systems, make sure you calculate the best direction to go for your particular situation.
