Photovoltaics nowadays found application in many places and in virtually any building size. Using a photovoltaic installation, the owner of the property also automatically becomes a producer of electricity, and thus reduces the amount of energy purchased from the network and significantly reduces the operating costs of his home. Considering that solar installation has become much more efficient and solar panels can generate much more energy than it used to be, and in addition panels are getting cheaper, the profitability of solar plants has become much higher and more and more people are choosing to install it. House designs are increasingly equipped with mono or poly photovoltaic panels and have space for heat pumps to make solar energy as efficient as possible. With the use of solar energy, we can afford to significantly reduce electricity bills, and our solar power plant equipped with mono solar panels and heat pumps will work all day producing electricity from the sun, while being inaudible.
Which solar panel should you choose?
Photovoltaic installations allow "to generate electricity from the sun", colloquially using a photovoltaic panel, we can generate direct current using solar energy. When choosing panels, we should know that they are basically divided into monocrystalline and polycrystalline panels.
- Monocrystalline panels - Photovoltaic modules used from monocrystalline cells are extremely popular because they have the highest efficiency and the best service life of up to 30 years. The equipment has a cell made of one crystal, so the crystal structure is evenly oriented in one direction. Such an operation, however, means high production costs, and thus a much higher purchase price.
- Polycrystalline modules - Polycrystalline panels are made of polycrystalline silicon and usually have a light blue color and the edges of the crystals are visible on their surface. Polycrystalline modules are cheaper to manufacture, yet their cell efficiency is slightly lower than monocrystalline cells. So they are very popular, because even 90% of installations are built on polycrystalline modules. No wonder, because polycrystalline solar installations have excellent value for money.
Operation of solar panels in winter
Although in practice many people know how we use solar energy, in theory few people realize how it works. When using photovoltaic panels, solar collectors should be bright to produce electricity. However, to start work we do not need very strong solar radiation, which is e.g. in the summer. In the winter season, our panels will also be constantly working, yes, there will be much less energy than in summer, but further solar collectors will work and will still be a producer of green energy.
How does a solar panel work?
Solar radiation falling on absober is transferred to the appropriate factor, which most often consists of glycol and water, and this solution gives hot water to the reservoir. For solar panels to operate at high speed, they must be facing the right direction. The largest amount of green energy is produced by the solar panel facing south, however, it should be remembered that their greatest efficiency is on warm days, and thus the largest increase in electricity is felt from April to September. Which does not change the fact that the solar plant also works in the winter, but to a much lesser extent.
