Which Type of Solar Panels
It’s imperitive that you realise that solar panels have two distinct funtions: generating heat and producing electricity. You also need be aware of the difference between the two as they are not interchangable However, both types can save you money and help you live a greener lifestyle.

Solar thermal collectors use the sun’s energy to heat water and other fluids, like oil. This method uses tubing in which the water runs through once heated You would use this sytem for heating pools, hot tubs etc. These panels can also be used for baseboard heating units and hot water flooring systems for heating building interiors. Once they are installed, there is usually no need for additional heating fuels. However, the systems usually require some kind of motorized pump to move the fluids.
Solar photovoltaic cells help produce DC (direct current) electricity. Most typically, they use semi-conductor material (silicon) in the panel, which interacts with sunlight to produce electricity. That electricity can be used to power household and electrical appliances, or even the entire house if the system is large enough. The panels are only able to produce electricity when they are receiving direct sunlight.
See The Many Uses of Solar Panels
In order to use a solar power system at night or during cloudy days, the electricity must be held in a battery storage system. You can purchase inexpensive lead-acid batteries (like the kind your car uses), but keep in mind that they must be filled with distilled water to maintain their charge. Some batteries are more costly, but they have particular advantages. Sealed AGM (absorbent glass mat) batteries will retain their charge without any maintenence. Freeze-resistant gel batteries are ideal for colder climates.
For both the thermal collector and the photovoltaic systems, glass panels are used to encase their collection systems, and both must have direct sunlight to function. Ideally, the panels should be installed in a south-facing location that provides optimum access to sunlight during the day. Solar panels can be used in any location to utilize the sun’s energy, but they are less effective in regions that typically have a lot of overcast days during the year.
It’s prudent to have a back-up supply in place even if you live in a sunny climate. Backup generators can be powered with biodiesel to be consistent with your green lifestyle. And you’ll be glad you have one if your battery storage becomes depleted or there is an extended period of cloudy weather.
