When choosing the best solar panel for you, you should not be guided solely by its price, since in most cases, the higher the power of the solar panels, the higher the price, but in the same way, the greater the savings, energetic and economical.
There is a lot of information about solar panels, and we highly recommend diving into the wonderful world of the Internet before choosing, but, in case you want to have a starting point, below, we explain what the different types of photovoltaic panels are and how you can choose the best one for you.
Types of photovoltaic panels
Before starting to define the types of solar panels that exist, you should know that 90% of solar panels are made with some variety of silicon, because its efficiency is directly related to the quality of the silicon it contains: the purer the silicon, it will better convert solar energy into electrical energy.
Other things that are important to know before making the choice is if your system will be autonomous (in which case you will use a storage system with batteries) or if you will be connected to the electricity grid. Your geographical location is also important, as temperature greatly affects the performance of your photovoltaic system.
There are two types of photovoltaic panels that differ mainly due to their quality (that is, the purity of their silicon) and manufacture.
Monocrystalline Solar Panels
They are the most powerful and efficient solar panels on the market. They are also the most expensive, because their manufacturing process involves obtaining cylindrical blocks of very pure silicon and a lot of silicon is wasted when manufacturing them.
They have a very characteristic appearance, since the cells are cut out on the 4 sides, which form a rhombus between each one. This class of solar panels has the longest useful life. There are guarantees that go up to 25 years.
Monocrystalline solar panel performs better than others in low light or high temperature conditions. Since their photovoltaic cells have the purest silicon, they are capable of capturing solar energy much better and therefore tend to be smaller in size.
Polycrystalline Solar Panels
This class of photovoltaic panels are also composed of silicon, but they are as expensive as monocrystalline ones, due to the way they are manufactured: they are manufactured by pouring the raw silicon into a square mold, where it is cooled and divided into sheets that are made up of small silicon crystals.
It is a simpler manufacturing process and wastes much less silicon than monocrystallines, but on the other hand, it does not have the same level of efficiency as monocrystallines and therefore, they tend to be larger than their counterpart, to achieve the same degree and power.
Polycrystalline panels are more sensitive to heat than monocrystalline ones: when the temperature is very high, your system does not capture as much energy as at a normal temperature.
So what is the best solar panel for your residential solar system? First, we must know that quality of the solar panel depends on the manufacturers and their products. Loom Solar produces the most efficient solar panels on the Indian market today. Their Shark 440 series can provide more than 22% panel conversion efficiency. The Monocrystalline solar panel from Loom Solar have the 30 to 50% more efficiency than the polycrystalline ones.
