How to Choose Solar Panels Correctly

Off-grid power supply is an ideal solution for owners of country homes. If installing solar panels used to be an expensive pleasure, the situation has changed dramatically now. On https://nenergy.com.ua/ you can even assemble a decent kit with a small budget to provide your home with an alternative power source.

Main Types of Solar Panels

All available panels are divided into the following categories:

• Monocrystalline;
• Polycrystalline;
• Amorphous.

The difference lies in the characteristics of silicon used in manufacturing. Monocrystalline panels are made from pure silicon. They have a high efficiency rating above 20%. In sunny regions, they demonstrate high efficiency.

Polycrystalline panels have an efficiency not exceeding 15%. However, they have an acceptable price and, with proper installation, can provide sufficient energy. Here https://nenergy.com.ua/solnechnye-batarei/ you can choose amorphous models suitable for areas where cloudiness predominates. Thanks to special technological solutions, they can extract the maximum from received light.

Lifespan and Quality

You should also consider the aging coefficient. Over time, equipment performance deteriorates. For example, monocrystalline panels may lose up to 25% over 25 years of operation.

Many factors still depend on the quality of the product. Based on this indicator, all panels are divided into three categories:

• A – highest quality. Even during aging, power loss will not exceed 5%.
• B – medium. Over time, power loss may reach 30%.
• C – low quality. Can lose more than 30% within a short period.

When selecting the right product, attention should also be paid to the surface. If it is covered with textured glass, this will increase the energy output from sunlight.

Power Calculation

To ensure uninterrupted power supply for the object, precise power calculations are required. This can be done independently. However, for this, you need to consider the following factors – monthly and daily energy consumption. Also, you need to take into account the length of daylight hours.

The most appropriate solution would be to consult with specialists. They will not only help you choose suitable solar panels, but also other equipment:

• Batteries;
• Inverter;
• Charge controller.

Such devices also significantly affect the efficiency and lifespan of the entire system.
