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.

A Key Element In Solar Water Heater – Efficiency
Solar energy most often associated with electricity production, while at the other side, the heating is also one form of solar energy use. Heating is not too difficult, in this case the efficiency is the key to maintaining your system from damage.

What is a Home Solar Power System
Executive Summary about Home Solar Power by Junaid Mohammad
Installing a home solar power system in your residence is good for the environment.
Requirement
Home solar power systems can be installed on almost all homes except for a very small home which have less than 120 square feet of roof. In most cities you require building permit to install home solar power system to your building.
Working of the System
Home solar power system is installed on the roof where the solar energy is transformed into direct current (DC) power. At night this home solar power system will not work. Most of the home solar power systems are interconnected with you utility. Your utility would provide power as usual at night and during day when your electricity demand exceeds that produced by your home solar power system. In case of cloudy days the home solar power system generates less power.
Home Heating
There are other technologies which convert solar energy into heat but this home solar power system is not used for home heating.
Home solar power systems don’t have any moving parts and solar modules are also tough.
Home Solar Power Systems Generation
Executive Summary about Home Solar Power by Erick Valdes
Home solar power systems have come a long way in a short amount of time. Home solar power systems are designed to absorb energy from the rays of the sun. Today, there are three basic types of solar power for use in homes and businesses:
1. If you install an extensive solar system on your home, you can completely disengage yourself from your local power company’s clutches.
2. Augmentation systems. Most homes that use solar power use augmentation systems. These solar systems are meant to power just one particular aspect of a home’s energy needs, such as outside lights, water heaters, or appliances. The rest of the home’s energy is supplied by a traditional electrical system.
3. Backup systems. These are solar systems installed to keep a home’s power running in case of a blackout by the power company.
Home solar power systems have greatly improved in quality and performance over the past few decades. Solar power makes a home more energy efficient and is more friendly to the environment.

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.
