Efficient Solar Panels

The Most Efficient Solar Panels

Furthermore, as traditional sources of power become evermore expensive, energy derived from renewable sources are becoming more attractive and sought after.
It is estimated, given the world governments' increasing commitment to the use of renewable energy sources, that by the year 2030 some 14% of the world's energy will be provided by solar power.

The term solar panel actually describes two types of device, to give them their technical names:
1. Solar photovoltaic modules
2. Solar thermal collectors.
Solar thermal collectors use the sun's energy to heat water (in domestic use) or other fluids. A good solar hot water panel is able to provide an average household with around a third of its annual hot water supply.
Solar cells are interconnected and assembled into panels which require protection form the environment to allow them to continue to work effectively. The construction of the frame within which the solar cells are housed is vital. A solar panel installation usually consists of multiple panels called an array.

Building integrated photovoltaics (BIPV) are increasingly being integrated into new domestic and industrial buildings either as a principal or an ancillary source of electrical power.
Solar Panels - What is Solar Energy and How is it Generated?
Wind, hydro, and geothermal power are examples of alternative energy, but the most popular option is solar energy.

We utilize solar energy with the help of solar cells. Remember using solar powered calculators in school? Those calculators had a small solar panel, usually above the display screen, which was responsible for powering the machine without the help of batteries. Basically, the solar cells used for these calculators are called photovoltaic (PV) cells, which convert sunlight into electricity. Solar energy is environmentally responsible; by not supporting coal/fossil/kerosene-burning energies, we contribute to improving the air-quality. Generating solar energy also reduces the amount of greenhouse gases in the atmosphere. Collecting and generating energy from the sun also reduces the risk of fires. Energy from the sun doesn't involve any such risks.
Solar panels are the safe, money-efficient energy option for the forward-thinking consumer.

Benefits - Solar Attic Fan Vs Electric Attic Fan

Solar powered products are exactly like that. One of the solar products is Solar Attic Fan. Let's compare the solar attic fan with electric attic fan and find out how you can save money.
The solar powered attic fan cost more than electric attic fan. The temperature in attic rises and causing the attic fan to work hard. The conventional attic fan has thermostat that turn the fan when the attic temperature goes beyond 125 degrees. Solar fan installs easily without need of any permits. Electric attic fan has to be replaced after 5-10 years. You do not have to replace solar powered fan for 20-25 years.

Benefits of Using a Solar Powered Attic Fans at Home - Are Solar Attic Fans Worth Using?
Solar powered attic fans functions mainly to ventilate attics and keep attics cooler. Units usually come fully assembled but anyone can install a solar-powered attic fan using conventional materials, tools and techniques. Due to the rising rates of the electric bill, solar power begins to gain its popularity because they provide high-capacity powered ventilation without electric operating costs. They are more affordable to operate than the conventional powered attic fans. - Reduces ambient temperature. Solar powered attic fans provide ventilation without added utility load while reducing summertime cooling loads. - Allows maximum exposure of sun to the solar panel. Because of how solar powered attic fans are uniquely designed, its mounting bracket houses the solar panel, which helps optimize the angle of the panel for it to use much more conveniently than the electric generated attic fan. Solar powered attic fans are adaptable for all locations, roof types and environments. With the solar powered attic fan's powder coat, it allows these fans to withstand any types of environment. Solar powered attic fans suits every attic to help reduce the heat while at he same time decreasing the electric bill. Solar powered fans are perfect for anyone in any environment around the world because of its high efficiency, environment friendly capability and lower electric bills.
