With the technological advancement, you will find many types of solar PV panels available in today’s market. However, in this article, we will discuss only two basic kinds of solar PV panels which are used extensively.
Two basic types of solar panels:
1) Polycrystalline solar panel and 2) Monocrystalline solar panel
These above-mentioned solar panels are used worldwide; particularly the polycrystalline solar PV panels are broadly used in the installation of the rooftop solar panels.
The differences between the two:
- Long-term functionality and warranty:
Different manufacturers offer different kinds of warranty for solar modules, as per the quality and expense of the panels. Generally they offer 25 years of warranty for Monocrystalline panels; however, a perfectly built Monocrystalline panel would have more than 25 years of durability. Besides, for the polycrystalline type, they offer up to 15 years of warranty.
Buying polycrystalline panels with long-term warranty is a smart decision because lots of local solar modules lose their efficiency in only 5 years. So, that time you can replace your panel if it comes under warranty.
Even, some panel makers offer the warranty on solar PV panels’ performance which is more helpful for us. Thereby, buy branded solar PV panels only from authentic dealers and enjoy the long-term performance.
- Need of sun tracking system:
Albeit Monocrystalline solar panels are more energy-efficient than the polycrystalline ones, you need the sun tracking system to get the full capacity of them.
The sun tracking system moves the panels at a right angle as per the sunray’s movement to prolong the power production. Well, this is not budget-friendly and thus, every householder doesn’t invest money on it.
- Effect of temperature:
Monocrystalline panels work well in high temperature. Besides, polycrystalline ones quit their efficiency at high temperature. However, it’s not a big issue.
- Size and energy efficiency:
Albeit compared to polycrystalline ones, the Monocrystalline Solar PV Panels are smaller in size, they are more energy efficient. Nevertheless, many people choose the polycrystalline type to eliminate the expense because they can’t afford the more expensive Monocrystalline panels.
If you want to install more than 1000 watts, then you should choose Monocrystalline PV panels. Well, the polycrystalline ones are a cost-effective solution for rooftop installation from 100 watts to 1000 watts. But it never means that they are not at all fit for bigger installations.
Comparison of energy effectiveness between Monocrystalline and polycrystalline panels is just about 2 percent. However, nowadays, polycrystalline ones are advancing and thus the difference is no more very big. So, if you are thinking to install solar PV panels in your home, then you can go easily with polycrystalline installations.
You need to keep in mind that there are many local brands are now available in the market. You have to be aware and avoid buying them as they are already rejected by the company. Bring home branded panel and install it to enjoy the hassle-free solar energy and also spare money in your electricity bill.
