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 Collector The Heart Of A Solar Heating System

Executive Summary about Solar Collector by Armand Hadife

Solar energy is accessible in plentiful places around the world. This high temperature produced can be exploited for heating air or water in houses and buildings

Using solar energy is a natural and affordable approach for spaces or water heating. When using solar power for heating purposes you employ a device that will allow capturing the heat of the sun. This device is called a solar collector. A basic solar collector can be made with no difficulties.

The next step is to find a system to help circulate water or air inside the solar collector. In general, devices like fans and pumps are used to push air or water thru the solar collector and from the storage tank to the house.

For the novice, making a solar collector can be a difficult and demanding project. This is why solar collectors are broadly offered online and in solar products shops.

How to Build a Solar Collector
Executive Summary about Solar Collector by Mick Jeys

Building a solar collector is the best way to save money on electricity bills, and can be used to generate electricity or to heat water. The two most popular uses for solar collectors are to heat water and generate electricity.

Solar Collector To Generate Electricity

Typically known as a solar cell or panel, they are typically made from titanium dioxide, and create electricity through the photovoltaic effect. It is now very simple to build your own generator at home quite cheaply by substituting titanium dioxide with cuprous oxide.

Solar Collector To Heat Water

The most common example of this type can be seen in common solar hot water systems, where the hot water tank is actually up on the roof with the solar collector. Trials are being held in Germany to use solar heated water from the summertime to heat homes in the winter.

Solar House Plans – The New Wave Of Our Future

Executive Summary about Solar House by Ernest Jarquio

Environmentalists rejoice! What is this new technology that will help save the earth? Why, solar house plans of course.

What Are Solar House Plans?

Well, the new phase in home planning is the plan for a sun-powered home.

Environmentally-Friendly Materials

The designer begins by drawing out the floor plan, planing to use recycled materials, eco-friendly building supplies and Energy-Star electrical outlets. For instance, the concrete slab flooring stores solar heat during the sunny days, then releases it at night, keeping the house warm.

Insulation

The designer uses only eco-friendly items for these tasks, such as recycled wood and green material for the insulation. After all this is planned, they continue onward to Energy-Star appliances and other electronic devices.

Solar Panels

The other panels installed are the thermal water heaters, which provide hot water constantly for the entire home. This hot water is often more reliable than a traditional hot water heater, supplying plenty of heat for the laundry, kitchen and bath.

How to Plan Your House for the Sun
Executive Summary about Solar House by Naomi Kendell

Every house will gain heat throughout the day as the sun shines through its windows.

And during the night as the temperature drops, this same house will lose heat to the outside through its walls, windows and roof.

1. Orientation.

By facing your house to the south (in the northern hemisphere) you will gain the rays of the winter sun. Afternoon sun comes from the west, so rooms like the dining room and living room can be placed on this orientation. The southwest corner of the house will be the sunniest – winter and afternoon sun.

On the northern side of your house, place service rooms.

2. Window Sizing

Out of all the materials your house is made of, windows lose the most heat. There is a balance here, because windows allow sunlight into your house. However even triple glazed glass allows more heat to escape than a well insulated wall.

The first is where your windows face. If you have most of your windows on the northern side, these windows will not get much sun during winter. They will be losing heat, but not gaining solar energy.

There is an optimal ratio of windows:wall for every climate. For instance in temperate climates, a window to wall ration could be: 30% window area to 70% wall area. The other ratio is in windows and orientation.

3. Materials

For instance, highly insulated walls will keep the heat inside your house. When analyzing your heat loss through your windows, you can gain some leeway through insulation. This air forms and insulating layer, slowing down heat loss.

Another way to use materials in your solar house plan is to take advantage of heat storage. It is radiating heat. The floor is insulated underneath to prevent heat loss. A well designed thermal heat sink will stay warm all night long.

4. Shading

Shading is an important part of the solar house plan. This is important not only for heat gains, but for preventing heat gains. In temperate climates as well, shading can be used to keep summer sun out and let winter sun in.

Using our orientation principle: your house is facing south. During the winter the sun angles low and reaches far into the house. This same shading will allow winter sun into your house.

Your latitude effects the angle of the winter sun. In conclusion – solar house plans are a great way to design houses that are warm and comfortable to live in, and save you money off your heating and air conditioning bill.

Using Orientation, Window Placement, Materials and Shading, you can design a house that responds to its environment and creates its own micro-climate of comfort.
