Solar Energy Applications
Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.
There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.
Photovoltaics System
Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.
Solar Cell Module
Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.
Thin Film Solar Cell
Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

“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.”
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

Using Window Film and Shades to Protect Your Home Interior From the Sun
Executive Summary about Solar Film by David Kraft
Home builders are reporting a higher frequency of larger and higher quantities of windows in new homes and home remodels being done. Rays from the sun can cause glare, hot spots, and fading to household items. One way to prevent these things from happening is to add a layer of window film to your windows. Window film can help to improve heating and cooling efficiency and block UV rays that cause fading to furniture, carpet, and other interior possessions. Film is available in tints that are not drastically change the color of the window but will still accomplish the goals of blocking the sun’s harmful rays. The key to window films is to have them properly installed by a specialist to ensure multiple years of functionality.
Solar screen shades are an alternative to window film that can accomplish the same things. They are available in varying levels of opacity and are available in motorized models that completely roll up nearly out of sight to allow homeowners to completely enjoy their large windows when they want to. Solar screen shades are simple, yet attractive ways to protect your homes interior and are available in a variety of colors that will enhance the appeal of any interior, regardless of design preference.
Choosing larger or higher quantities of windows in your home opens you up to more risk for faded interior and decreases in your home’s heating and cooling system efficiency.
