WHY CHOOSE SOLAR PANELS?

Solar panels take advantage of one of nature’s most powerful yet free resources: the energy produced by the sun. Solar panels, also known as photovoltaic systems (PV systems), use semiconductor technology to convert energy from sunlight into electricity that can power your household.

Union Service is Yiwu’s Largest Trading Company over 1200 staffs, established in 1997. We also built office in Yiwu/Ningbo/Guangzhou,ect and export & wholesale all kinds of China solar panels, and provide one stop export service. If you want to import solar panels from China, please contact us at once, we will provide you best price with best service!

Electricity all year round

  • Solar panels generate clean, emission-free electricity to power your home all year round, Solar panels can work efficiently all year round. While they work optimally during the sunny months, they also produce a considerable amount of electricity during cloudy days and in the winter time.

Cheaper Electricity Bills

  • With an increase in electric gadgets comes an increase in utility bills. You can reduce your electricity bills by incorporating solar panels into your household. The energy produced by solar panels is completely free, and surplus energy can always be stored for future use, or exported back to the grid.

Reduce your carbon footprint

  • Switching to solar energy significantly reduces your carbon footprint as it is a green, renewable source of energy. Unlike traditional electricity generators, like fossil fuels, coal, and oil, solar power does not release harmful carbon dioxide (CO2) or other pollutants.

What Types of Solar Cells Are There?

The most common types of domestic solar panels are monocrystalline panelspolycrystalline panels, and thin-film solar panels. There are additional types of solar panels on the market, however, these three are most commonly used for domestic purposes.

Monocrystalline Solar Panels

Monocrystalline solar panels get their name because they are made of one piece of silicon. They are known as the most efficient

When produced, the material that is used is single-crystal silicon, which is then cut into wafers. This allows for the electrons to flow freely, resulting in the high-efficiency rates. This also makes them the most expensive

Polycrystalline Solar Panels

Polycrystalline solar panels are produced by melting several pieces of silicon together into square moulds, forming the solar cells. As there are multiple crystals in each solar cell, there is less space for electrons to move around, resulting in a lower efficiency rate compared to monocrystalline cells. Polycrystalline panels are easier to produce than monocrystalline ones, and therefore also cheaper.

Thin-Film Solar Panels

Thin-film solar panels are easier to produce as they require less material. For that reason, they are the cheapest type of solar panel on the market. Thin-film panels are the least efficient on the market and require the most space. They are more tolerant to high temperatures, making them suitable for hotter countries.
