Types of solar panels
There are two types of solar panels we sell best: monocrystalline, polycrystalline. Different types of solar panels serve different needs and purposes. Hopefully, this list will serve as a guide to make a good purchase for solar panels.

Monocrystalline and polycrystalline solar panels serve the same function in the over solar PV system: they capture energy from the sun and turn it into electricity. They are both made of silicon wafers. To build a solar panel, wafers are assembled into rows and columns from a rectangle, covered with a glass sheet, and framed together.

Monocrystalline solar panels
Monocrystalline solar panels are generally thought of as a premium solar product. The advantages of monocrystalline solar panels are higher efficiency and good heat tolerance characteristics with a small footprint.

Polycrystalline solar panels
Polycrystalline solar panels usually have lower efficiency than monocrystalline options, but their advantage is a lower price point and the most popular choice in installs.

Solar panel cost
The solar panel cost depends on the size (in Watts), the physical size, the quality of solar panels, the brand, the durability (or warranty period) and the certifications of solar panel might have.

The first factor people consider may be the solar panel cost. However, it shouldn’t be the one factor to be considered. Each type of solar panel has its own unique advantages and disadvantages. How to choose suitable solar panels can be important, because they have a long lifespan (more than 30 years), so it is more important to ensure a good quality system than choosing the cheapest option.

Energy efficiency
Most solar panels can have different specifications indicating their technical attributes. The power output of your whole solar system matters more than the size or number of panels. The more efficient, the better (and more expensive), because the more watts of electricity you will get per square meter of solar panel. It is not always the best choice to get the biggest and most efficient solar panels, since you might end up spending more money than you should to cover your energy needs.

Size
To calculate how many solar panels you need, you should make sure to install a solar system that is big enough to power all your appliances, and usable surface area, the climate and peak sunlight in your area. The physical size of the panel will vary depending on how powerful the system is and the type of solar cells used to build the panel.
