Guide to buying a solar panel
The use of renewable energies through solar panels is booming both in family homes and in companies, because it is a way of improving the consumption of electrical energy, with less impact on the planet. Currently, there are many options, but not all of them are of quality, so if you want to make an efficient choice, you can review the following guide to buy the best solar panel, a section designed to explain the properties that you should check in this equipment for obtaining alternative energy.
Before making a hasty purchase, it is necessary to decide what style of solar panel to purchase. On the one hand, there are thermal solar panels and, on the other, photovoltaic solar panels. Although they have similar aspects, their operation is different, hence the importance of differentiating them.
The former are usually used for the generation of hot water and heating. Meanwhile, photovoltaic panels are designed to generate electrical energy.
It may be that specifying how much a solar panel costs is a complex task, because the price changes at the rate of some variants. One of them is due to the type of panels. In the market you can get several options of photovoltaic panels such as monocrystalline silicon, polycrystalline silicon and thin film. Although they serve the same purpose, their function, quality, and performance vary by type.
In the case of monocrystalline silicon photovoltaic solar panels, these are usually the most expensive because they are manufactured with cylindrical blocks of pure silicon. Their operation is efficient, even if there is little sun, so they are recommended for provinces where solar energy is low, there is a high budget and a high electricity demand is required. On the other hand, polycrystalline silicon photovoltaic panels are similar, but the concentration of the latter is lower and, therefore, so is its efficiency.
In terms of price, they are cheaper because their manufacturing costs are reduced by pouring the silicon into square molds, where it cools and divides into sheets. Its operation is adequate to provide energy for the home. Finally, thin-layer panels are the cheapest, because they are made with lower-end materials and with a simple construction.
Maintenance and materials
When establishing a comparison of solar panels, it is necessary that beyond the price maintenance is studied to extend the useful life of the panels and not have to make a new investment after a couple of months. For this reason, it is important to have equipment that has a high degree of resistance and quality, with waterproofing and that is made of high-end materials such as galvanized aluminium.
In general, the maintenance of this equipment is simple, it is only necessary to expose it to wind and water, hence it is necessary that they have insulating material and care must be taken that the rain is not acid, nor the sea wind. On the contrary, it is preferable that it be crystal clear water or opt for professional maintenance.
A solar panel may be good and cheap, but for its quality-price ratio to be really effective, it is necessary to specify what is being purchased. In the market, you can get from individual solar panels to the complete installation kit that will allow you to obtain renewable energy to power the electrical part of the home, business, caravan, among others.
It is necessary that, before buying, the user knows the basic operation of a board and understands that only the panel will not work. So you can choose to buy the parts and elements separately or purchase a kit. The important thing is to make an analysis of the investment and be able to specify which parts the kit includes and which must be purchased separately.
Power and efficiency
Solar panels or plates work with technical aspects that cause their performance and capacity to vary. On the one hand, it is necessary to know how many cells or cells are integrated and what is the power of the battery. It will depend on this to acquire one type or another of panel. For example, two monoblock batteries are suitable for 24V panels.
Likewise, it is necessary to specify the output power or the electrical energy that the panel is capable of generating. This power usually varies according to the temperature or
