New Solar Technology

Solar technologies is now highly developed, with some progress is being developed to be used every day.

Below 10 Solar Technologies to note:

1. Water Heating Solar Panel: Pyron Solar Triad uses a special design, short focal-length, lens in the acrylic concentration to reflect and accept the light, effectively concentrate 6.500 solar power in the form of a small light. The second lens capture light and focus on PV cells. According to related companies, HE Optics System produces 800 times more energy than the silicon solar cells.
2. Home Solar to Hydrogen Storage: An MIT professor Daniel Nocera, build a company this year to market a technology that can split water and store solar energy. The key of this company is to achieve a breakthrough solar energy to make solar power cheaper.
   “The idea is to use solar panels to power the electrolyzer to produce hydrogen which would be stored in tanks. When people need electricity, the stored hydrogen would put through a fuel cell.”
3. Solar panel roof that can be printed and painted: If solar power is easy to install as to paint your roof with sunlight resistant paint, it will lower the standard for the installation of solar power at home. This technology called silicon ink, and according to the U.S. National Renewable Energy Laboratory, solar cells showed 18% energy savings.
4. Large Panel Solar Film: SunFab ™ system uses silicon thin film technology to market the largest and most powerful panels in the world and combines inexpensive material.
5. Organic Solar Concentrators: Engineers at MIT have created a method to transform glass into a high-tech solar concentrator, using color glass to collect and emit light which is usually missing from the panel surface. This technology can create a building for use with glass window film to gather strength. Other companies, GreenSun, has developed a panel of light color where it catch the other parts of the spectrum of the sun, and does not require direct sunlight to work.
6. Space Based Solar: Japanese are developing a giant space station with solar power generators to transmit solar power to earth from 36.000 km above the earth within the next 30 years. The Japanese Government supports $ 21 billion project, which includes a space station solar power with solar panels cubical 4km, save electric energy of 1 gigawatt, enough for 300,000 homes in Tokyo.
7. Solar Roads: Solar Roadways concept, will make a way to use glass panels to collect and distribute solar energy to illuminate the light at night and hot in winter, with enough remaining energy to light homes and businesses. Discoverer, Scott Brusaw, estimating each mile of solar panels can be illuminated 500 houses, and is expected to make a panel for 12×12 need cost about $ 5,000.
8. SunCatcher: Stirling Energy System, contains a solar concentrator in the bowl structure supported by a convex mirror, can be used in Arizona soon. SunCatcher using glass system fitted with a parabolic bowl for concentrating solar power in high-efficiency Stirling engine, with each bowl produces 25.000 watts.
9. Solar Nanotechnology: Research workers at McMaster University in Ontario has developed a light-absorbing nanowires formed of excellent photovoltaic materials in thin but durable carbon-nanotube fabric. They also use small particles in a flexible polyster film where can lead to solar cells that are both flexible and cheaper than today’s solar cells.
10. Grid Ready for Solar: Andalay AC solar energy panels, made with Akeena Solar technology, integrate the racking, wiring and electrical grounding components to the panel. According to the company, this will against the damage, a lot of money in saving for 30 year lifetime. Andalay AC solar energy panels produce a safe AC power, and can be a safe installation process for users.

Solar Tubes

Solar Light Tubes

Initial concept of light tubes developed by the ancient Egyptians, namely by direct use of natural light tubes with reflective material. This is the concept of the oldest and most widespread type of natural lighting of interior space.

Light tubes are also known as “tubular skylight”, “SunScope” or “Tubular Daylighting Device” allow natural light into the darkened interior room of buildings and houses. The people enjoy the natural lighting provided by skylights. However, skylights are often not evenly distribute the light, is the loss of a significant source of energy, and UV light can cause damage to the carpet and furniture. Light tubes, on the other hand, using the sun for lighting interiors without the shortcomings associated with conventional skylights. To prevent the danger of ultraviolet radiation (UV) from the carpet and furniture fading, UV inhibitors formed a dome roof on most models. Another bonus when choosing light tubes is that they provide far more heat slightly, as did the standard skylights. Because of the lack of acceptance of this heat, tubular skylights to save money on air conditioning bills during hot months.

Taking advantage of free sunlight as much as possible, the pipe hole collect sunlight from the roof dome light collector consists of an acrylic lens, bounce it to the bottom of a tube with a highly reflective interior coating, to pull the lens cap is similar to conventional recessed lighting equipment and diffuse sun light evenly throughout the interior rooms. The tube can be bent and adapted to drive around the garret or ceiling obstructions with small loss of light transmitting and can often be installed in less than three hours. Not like the ceiling of need roof to the ceiling of the timber-framed shaft and covered with drywall or wood panels, and the need for structural modifications, so installation is simple and relatively inexpensive.

Roof mounted dome made of high quality acrylic resin specially formulated to enhance the impact strength, chemical, weather resistance and high clarity.

Light tubes can be installed on almost all types of roof materials, including wood and asphalt shingles, concrete and ceramics, and metals. Thanks to a highly reflective coating on the rod, the tube can work efficiently from sunrise to sunset.

Most of the producers of glass tubular solar roof offers a 10-year warranty against defects in materials and post-installation cracks or discoloration. Tubes solar installation contractors generally offer a 2-3 year warranty for the installation of weatherproofing and storm protection.

The average size of the tubular skylight ranges between 10 and 21 inches (254 and 533 mm), diameter, which effectively light of 100-600 square feet (30,48-182,88 meters), interior space. The main factor in choosing a general measure of the distance between the roof rafters and / or ceiling beams.

Prices range from around $ 171.00 to $ 423.00. Installing a solar tube usually cost between $ 500 and $ 800. Both depend on the size of tubes and features installed.

Light tube options include:

• Dimmers which allows the natural lighting level of a room that will turn up or down according to demand.
• Light kit for night time lighting.
• Ventilation fan kit

Energy-efficient light tubes is an important part of the house and environmentally friendly buildings. Natural light effects on your physical, emotional and psychological well known as the rooms benefit from natural sunlight free will positively impact our environment for future generations. They are environmentally-friendly way to naturally brighten every room, a smart alternative to skylights and artificial lighting.
