Features of the choice of solar cells

Progress does not stand still, introducing every year technical innovations that greatly simplify the lives of people. The basis for many of them are solar panels, whose main advantage lies in significant savings for their owner. Because of this feature, this energy accumulation system has become popular among many domestic entrepreneurs and ordinary citizens who are actively installing solar panels in their home areas.

Potential buyers are often lost in the range of products and companies in search of a suitable option. Consider the features of the choice of solar cells.

Solar battery (solar system) is a device whose surface consists of a set of photovoltaic cells.With their help, solar energy is converted into a constant electric current and accumulates in the battery.

The solar panel system includes:

• photovoltaic modules - are needed to capture solar energy for subsequent conversion into electricity;
• current transducer - converts direct current into alternating current;
• accumulators - means for accumulating the received energy;
• battery controller - controls how charged a battery is.

The system is fully autonomous and provides uninterrupted flow of energy through the main and additional batteries.

Currently, there are various models of this system: from microbatteries in the calculator to large-scale projects that can occupy a large area and generate electricity for large enterprises. In many developed countries, solar panels are an integral part of the daily life of citizens. With their help, various electronic devices and even eco-machines are charged, and also current is generated to service entire buildings.This is a sure and very budget way to give food not just to one street, but to the whole city.

Although solar panels abroad are low cost and high in demand, there are opponents of this device. They are convinced that the main flaw in such a system is that there are much more cloudy days in a year than sunny days. And this is true, however, most modern models have such high power of photovoltaic cells that they are able to get enough energy even on a rainy day.

Before making a purchase, you should be familiar with the types of solar cells that modern companies offer. From their choice depend on the performance, durability, power and price of the device. The difference lies in the material from which the photocells of the system are made. There are several options.

The most budget view, designed to power energy compact equipment.

Differs in low price in contrast to batteries with monocrystalline silicon photoconverters, however, it is less efficient in the process of obtaining and processing solar energy.This option is designed for private individuals to purchase electricity for small areas.

The most expensive model, which is characterized by high performance. Such batteries, as a rule, have a compact size, but at the same time are characterized by a high power generation capacity. The main advantage is also in high quality - photovoltaic cells are extremely resistant to moisture and other adverse conditions.

The acquisition of a solar battery should focus not so much on the budget, as on the need to ensure the uninterrupted supply of current to individual equipment, premises or an enterprise. The more qualitatively the photocells are made, the better the result will be and the more durable the product. If the choice is between the acquisition of panels of single crystal or polycrystal, it is best to choose the first option.

The most obvious advantages of this system include the following nuances.

• Renewability. Unlike other sources of electricity (for example, fuel), solar energy is a renewable resource that will keep the battery running as long as the solar system exists.The quality of electrical supply will depend only on the type of device and the state of its elements. The power of modern models ranges from 200 to 500 watts.
• Environmental friendliness. Solar panels are a significant step for humanity to protect the climate from global warming. It is they who establish many enterprises that advocate for the protection of the environment. This system does not emit any corrosive and toxic substances that can harm nature, but at the same time provides the supply of electricity not worse than other sources.

• Efficiency. The system does not require large additional costs, except for the annual cleaning of photovoltaic cells. By purchasing a solar battery, you can use the electricity it generates for several decades, significantly saving on the absence of a check for electricity consumption.
• Availability. It is possible to purchase and install this equipment without any obstacles. In many European cities, solar cells are the main source of electrical power.
• Noiselessness Autonomous operation of solar cells is not accompanied by noise. Its easy and comfortable to use.
• Durability. Most solar panels work up to 20-30 years.

However, this system has certain disadvantages.

• High price. Especially in Russia, where the use of solar cells is still not widespread, it is problematic to find a quality product at a low cost. You can contact international suppliers to save money, however, along with tax and delivery, the price will not differ much from that offered by domestic sellers.
• Inconstancy. Electricity from these batteries is converted from sunlight, but it is clear that this can be a problem at night and on cloudy days. For a powerful system, this will not be a tangible problem, but it may affect more budget models that cannot receive enough energy in long cloudy weather.

• Low power density in contrast to the electricity produced by using fuels such as oil, coal, gas.
• Low availability of spare parts. The range of not all companies provides spare parts for their models.That is why in the event of a breakdown it will not always be possible to properly and quickly repair equipment.

The advantages of solar panels outweigh their disadvantages. That is why the demand for this system from the Russian buyer is increasing every year.

Getting acquainted with a wide range of products of modern brands, you should pay attention to the following models.

• Exmork 230W 24V. The panel is assembled from polycrystalline solar cells and is intended for outdoor equipment. The operating range of the battery ranges from -40 ° C to + 80 ° C, which is optimal for the harsh Russian winter and hot summer.
• One-Sun 250W 24V. Photo cells are made of monocrystalline silicon. The model of the budget line with a favorable ratio of price and quality, so it is extremely relevant among domestic buyers. The manufacturer guarantees high performance and reliability of the module.

• E-Power 200W 18V. The flexible system makes this product versatile, it is convenient to mount it on various uneven surfaces. Monocrystalline panel is extremely light and has high power. Suitable for use on vehicles of various types.

The popularity of solar panels is increasing rapidly every day. Businessmen willingly put them in their factories, while ordinary citizens equip their summer cottages with them. Manufacturing companies offer interesting models for each of these cases.
