How to choose solar panels
Solar panels — not the cheapest pleasure. They can cost three hundred and ten thousand dollars. And the price and quality — things not interconnected to a power plant. Even an inexpensive panel can work long and effectively.
The price is influenced by power. The most important thing in such panels is their capacity. Expensive battery is usually very powerful. In fact, price is the sum of the number of watts. And it's obvious. Solar panels with a capacity of 100 Watts, will be the generators stavatti energy per hour and a capacity of two hundred — twice. Therefore, the second costs more than the first two times, it is whatever time it is more powerful.
Power affects the size. More powerful battery more than one that has less power. In addition, there is a certain type of solar panels. Type also affects the cost.
The basic rule — the solar panel for its power and size must be sufficient to provide their energy all home devices. It is necessary to choose also the correct size battery to fit in the place that the purchaser took them into the apartment, cottage or house.
Usually the batteries from silicon or thin films cheaper than those that are mono or polycrystalline. But silicon options, for example, are not as powerful and require open space if the buyer is going to put them on the roof. So if you pick the battery out of silicon, it is worth considering and will I need an additional battery? The roof space may not be enough, have to buy other options and then spend the money.
Thus, the cost of the panels consists of their power, size and reliability. If you buy these batteries, only focusing on the price, you commit an error. The panels can not be placed in the premises, their capacity is insufficient, they are not very reliable, and will not have all the certificates of conformity and quality.
The quality levels of the panels
Experts in the field of energy-saving technologies all solar panelin divided into three quality levels. As already written above, the price is not always the main criterion. Great role play and materials panels, and the technological nuances of the Assembly.
So, the first level is only two percent of the manufacturers of such batteries. The manufacturer is responsible for each phase of the panels. This process of management is considered to be vertical integrated. Is a venture capital company that invest heavily in innovation policies, namely in the development and implementation of innovations. The whole process of such production is optimized and automated. Usually such companies exist in the market more than five years. Material for batteries, which made these companies – silicon is very high class and level. These batteries last a long time, the quality of their functions as possible. It's the most efficient panels, but they are expensive.
The second level of quality provided by companies that use automation not only in production, but also manual labor. These companies operate in the market from approximately two to five years. The quality of these batteries is higher, but the price is acceptable.
Unfortunately, ninety percent of the market in solar Panellinskogo quality. The manufacturers will not invest in innovative activities. Such companies are only responsible for the Assembly of batteries. Moreover, the Assembly takes place using manual labor. The price of such panels is low, as the quality.
Types of solar panels
Among experts there are three types of panels, which are powered by solar panels. The first option is monocrystalline panels which are made of silicon. They're effective and are large in size. These batteries fit easily on the roof of the house or cottage. This is the most expensive, but the quality of the panels. They are suitable for those who appreciates quality and doesn't need the money.
The other kind is a polycrystalline panel. They are made of polycrystalline silicon. They are effective and popular. The fact that the ratio of productivity and efficiency optimal. In size and efficiency, they do not differ from the single-crystal counterparts. Now in Europe the standard accept such batteries. Experts believe that this variant is ideal for use in your own home.
Finally, the cheapest option is solar panels, which are formed from thin-film silicon. They are not very powerful and take up much space. The only plus — reasonable price.
An important factor when buying is the warranty on the battery. If, for example, the panels have a warranty of fifteen years, then they have to have a margin of safety for this term and to develop a set amount of power. Usually very high quality panels have a twenty five year warranty. Known brands offer such guarantee period. Experts recommend buying the batteries of known brands.
What are the main technical characteristics
Solar panels have different characteristics. Main is the deviation. Have a good battery it always has a positive value. Simply put, if the battery needs to produce 300 Watts, in reality it will produce - 305 or 310. Bad battery produces less energy than specified in the instructions.
Another characteristic — temperature coefficient. It reflects how to work the panel in the heat or cold. Measurement of the percentage of one degree Celsius. The better the bar, the less this percentage.
Three baseline is a guarantee of the durability and strength of the panel. The higher these indicators, the more confident in your product manufacturers of solar panels.
Thus, when selecting solar panels should take into account not only the price, but the battery materials, technology of its production. Before going to the store, you should read reviews about those or other producers to compare different specifications.
