Solar panels are one of the most promising sources of electric energy not only for production enterprises, but also for domestic use. If you decide to purchase these devices, then you need to pay attention to many factors. Consider the most important criteria for solar modules.
The main criteria for choosing solar panels
Power. This characteristic has a direct impact not only on the efficiency of the device, but also its cost. Naturally, the more powerful the solar battery, the greater the amount will have to pay for it. For example, a panel with a capacity of 100 W is capable of generating about 100 W electric energy per hour, and a device with a capacity of 200 W is twice as much as. Of course, in the second case, you need to pay a lot more for the solar battery.
Dimensions. It should be noted that the power of the structure is exposed to power. A 200 W panel will be much more than a 100 watts device.
Price. As already mentioned, the price of solar panels will depend on their size, power level, manufacturing company, etc. As practice shows, choosing panels, starting exclusively from their cost is not a very good solution, since they simply can not accommodate where you plan to put them.
Overview of the main varieties of solar panels
Monocrystalline plates are considered the most effective and small. However, they differ in high cost. If you plan to take powerful solar panels, and you are not limited financially, then these devices will be an ideal solution.
Polycrystalline – solar panels made of polycrystalline silicon. These are quite effective and popular devices, as they guarantee an excellent balance of economy and high performance.
The cheapest solar batteries are based on, based on thin -legged silicon. However, among potential buyers, they are not in particular demand. And this is not surprising, since their effectiveness leaves much to be desired. In addition, this design is very bulky. Accordingly, in terms of size and efficiency, thin -sex solar panels are significantly inferior to monocristallic and polycrystalline models.
