Cost
The sunlight is considered ecologically pure, silent and a reliable source of energy. If to place solar batteries on a roof of own house at presence of clear weather, sunny days long time, you will be provided by alternative energy, sufficient for illumination of your habitation or a site.
Solar batteries for a long time it is already used in the Europe. There the state buys the energy received from alternative sources, for a ceiling price. Thus, the energy received in the summer from a roof of the private house is transferred networks, and in a cold season, at deficiency of a sunlight, energy comes back back.
The principle of action of solar batteries consists in direct transformation of a sunlight to an electric current. Thus, you can use various devices or reserve it, using storage batteries. That then her to take advantage. Usually solar batteries work in pair with an available network and are applied to generation of ecologically pure electricity for networks of the centralized electrosupply.
Types of batteries
Batteries happen: monocrystal, polycrystalline and thin-film solar panels.
Monocrystal
Are considered as the most widespread and gather in a uniform design from a plenty силиконовых cells. They are formed in strong стеклопластиковом the case which protects a design from influence of a moisture and a dust. Light, getting on these cells, due to photo-electric effect turns to the electric power.
Such batteries differ ease and compactness, and ability to an insignificant bend, allows to establish them on rough surfaces. However, small overcast already essentially reduces capacity of installations and almost completely blocks their work.
Polycrystalline
Have the low cost price and can be considered as the best alternative monocrystal. They differ the design - crystals in them have the different form and orientation. Work is better, than monocrystal at cloudy weather and under a greater corner of falling of solar beams. Them use for electrosupply of lanterns of street illumination, the medical equipment, зарядки accumulators ноутбуков, phones, for illumination of apartment houses. Monocrystal and polycrystalline a plate can serve more than 30 years.
Thin-film
These are cheaper models of solar batteries. Them make by напыления silicon on a necessary surface. They can be curtailed into a tubule or to give other form, therefore they are very popular among tourists, hunters, fishermen, there, where mobility and small weight is required. They are not afraid of a dust and do not demand an ideal corner of hit of solar beams on a surface. At overcast or bad weather conditions efficiency of thin-film solar batteries decreases only on 10-15 %. Badly that for their work greater areas are necessary that complicates their application in a conditions of life. They can be mounted on the ground areas, roofs of buildings. Service life small - only 7 years.
Kinds of cameras mounting.
Independent.
Apply, when there is no an opportunity to be connected to a network.
For storage of energy storage batteries are usually used. Installation of system on solar batteries are favourable already because capital expenses for installation will be equal or below cost of connection to the general network.
Connected to a network.
The solar batteries connected to a network of centralized electrosupply. Can be used for generation of an additional electricity.
Reserve
Here solar batteries are connected to networks of poor quality and used at switching-off
The basic power supply or at a bad and weak pressure. For accumulation of energy accumulators be required.
Cost
Solar batteries are good for economy of the electric power in small volumes and protection from possible switching-off of energy, but poorly accessible because of their high cost as the price the watt-hour is more in comparison with other sources.
Cost of system of solar batteries depends on capacity and quantity of solar panels. We shall compare the prices:
Monocrystal - from 1000 руб for one panel capacity of 10 watt up to 19550 руб capacity 230 wt.
Polycrystalline - from 800 rub capacity 5 wt up to 11000 rub, capacity 230wt.
The thin-film battery 1 wt will manage capacity in 45 rbl.
