What is a monocrystallic solar panel?
Single-crystal silicon photo-elements are most effective and popular among consumers. They are produced by casting high-purity silicon crystals, in which the melt solidifies on contact with the seed crystal. In the process of gradually cooling silicon solidifies in the form of a cylindrical casting of a single crystal of diameter 13 – 20 cm in length with up to 200 cm thus obtained ingot is cut into thick leaves 250 – 300 microns.
Such elements have higher efficiency compared with the elements produced by molds in other ways, efficiency reaches 19%, thanks to the special orientation of the atoms of a single crystal, which contributes to the mobility of electrons.
Silicon permeates the mesh of metal electrodes. Traditionally, single-crystal modules are inserted into the aluminum frame and covered with an impact glass. Color photo of single-crystal elements – dark blue or black.
Sphere of application
Solar panels are reliable, durable and easy to install, since it does not contain moving parts. Solar panels can be used where conventional electricity is not working properly and a large number of sunny days. Examples of solar panels: on rooftops to generate electricity, on street and garden lamps for lighting, charging batteries, providing electricity to equipment on boats, radios, pumps, alarms and so on.
What is a thin-film battery?
Thin-film technology allows making cheaper production costs panel. This circumstance makes film panels more attractive for the construction of larger “farms” on the production of electricity from sunlight, when the sun farmer is limited not so much an area of land as the cost of installing the batteries. Can be installed not only on the roof, but also on the walls of buildings.
Thin-film panels require direct sunlight, working with the scattered radiation, thus the total energy resulting output for the year increased by 10-15% than produce traditional crystalline solar panels. A thin film is much more cost-effective way of energy production and can replay the single crystals in areas with a hazy, cloudy climates or in those industries, which is characteristic of air or dust to high content of other particles.
Sphere of application
Thin-film panel in 95% of cases are used for on-grid “systems that generate electricity directly into the network. These panels need to use high-voltage controllers and inverters, not stick with low-power home systems.
Although the cost of thin-film panels is low, they occupy a much larger area (2.5 times) than the mono-and polycrystalline panels. Because of lower efficiency of thin-film panels effectively used in systems 10 kW or more. To construct a small autonomous or stand-by power supply systems used monocrystallic and polycrystalline panels.
What is polycrystalline battery?
An alternative to single-crystal silicon is polycrystalline silicon. He has a lower cost. The crystals in it are more modular, but have a different shape and orientation. This material, as compared with the dark single crystals is different bright blue. Improving the process of production of elements of this type can now obtain the components, characteristics of which are only slightly inferior to the electrical parameters of single crystal.
Sphere of application
With a solar panel system, you can:
- To highlight and provide electricity to homes and cottages, schools, hospitals, offices, farms, greenhouse complexes, etc;
- Lightning of parks, gardens, yards, roads and streets;
- Ensure telecommunications, medical equipment with power;
- Supply power to the oil and gas pipelines;
- provide electricity supply and water desalination;
- Perform charging of mobile phones and laptops

No doubt energy has an important place in our lives. In many cases people want to have an independent or alternative energy supply source. If you are one of those who search information on hot water solar panels, please go to this site. There you may find lots of details about air source heating and how to buy it.

Currently the Internet technologies provide us with a really unique chance to choose what one needs for the best price on the market. That is why if you are properly armed with the info in your sphere of interest you can rest assured that you will in any case find the way out from any bad situation. So, please make sure to visit this blog on a regular basis or – best of all – sign up to its RSS feed. Thus you will have a direct shortcut to the newest info updates about renewable energy here. Blogging can be helpful, you just need to know how to use it.
