There are different types of solar panels, but in this article, we will introduce Polycrystalline Solar Panel buyer’s guide. Finally, we will be talking about the best Polycrystalline solar panels in the market.
Poly-crystalline or Multi-crystalline -as some manufacturers like to call them- solar panels are quite different from other types of solar panels. In fact, they are made from silicon, and the panel’s wafers are made by melting several remains of silicon together, which explains the eventual square shape of the panel. Therefore, it is easy to recognize Polycrystalline solar panels, as they usually have a shining blue color since that they consist of multiple crystals of silicon.
Capitalists have taken advantage of the growth in demand for the Polycrystalline solar panels by producing so many Polycrystalline solar panels. As a result, consumers of Polycrystalline solar panels are now puzzled as to which Poly-crystalline solar panel they should purchase. With that in mind, this guide aims to evaluate and let you know the best Poly-crystalline solar panel to buy.
Solar energy has evolved from being luxury products to being essential needs. As you are aware, the ozone layer is being depleted daily due to the emission of ozone-depleting substances (ODS), which explains why we need to turn to green energies, and solar energy particularly.
Polycrystalline Solar Panels Buyer’s guide
If you are new to the world of green energy, you might not be familiar with some terms often used when discussing about solar panels. Below are some of the terms we think you need to understand first before plunging into the profound sections of the article.
The efficiency range of the Polycrystalline Solar Panel would be appraised in percentage. Accordingly, it is used to show the power of a single Polycrystalline Solar Panel to convert cornered sunlight into electricity. When the efficiency range of the panel is high, it indicates that the panel has a higher ability to convert sunlight into electricity.
Minimum and Maximum Temperature
The temperature is an essential factor to consider before acquiring a solar panel. Therefore, every Polycrystalline Solar Panel usually has a minimum and maximum temperature range. The moderate acceptable range is -40°F(-40°C) for the minimum temperature and up to 185°F(85°C) and higher as maximum temperature.
The weight of the solar panel might be a big deal to consider before procuring a Polycrystalline solar panel especially when you need to install it on the summit of your home. You don’t want to apply too much weight on your roof. The lighter the density of the solar panel, the better for the summit of your homes in which the panel is placed.
This means the lifespan of the Solar panel. The Solar panel would most likely alter the aesthetics of your home so you want to be sure that the solar panel you are buying is of high quality and would last long, thus limiting the number of times you might have to alter your home.
When a company is eager to sell, they would be open to giving assurances for the goods. This is quite common when you buy electronics and appliance such as mobile phones, laptop, blenders, etc. for the seller to give a warranty. The crux of warranty is to bulwark you from buying an item that is faulty due to the act or omission of the manufacturer or because of environmental issues.
