The 3 Different Types Of Solar Panels – Explained

1. Monocrystalline Solar Panels

Monocrystalline or single-crystal panels are made from a single pure silicon crystal that is cut into several wafers. Since they are made from pure silicon, they are easily identified by their dark black color. Pure silicon makes them long-lasting which is excellent for sailing. You do not want to lose your power out in the middle of the ocean. Monocrystalline solar panels can reach efficiencies higher than 20 percent, while polycrystalline solar panels usually have efficiencies between 15 to 17 percent.

2. Polycrystalline Solar Panels

This type of solar panel is made up of different silicon crystals instead of just one like the Monocrystalline. The silicon fragments are melted and poured into a square mold. This makes polycrystalline cells much more affordable and gives them that characteristic square shape. These types of solar panels have a blue look to them, making them easy to tell apart from other types. Polycrystalline panels will usually come in smaller wattages compared to monocrystalline panels.

3. Thin Film Solar Panels

Unlike monocrystalline and polycrystalline solar panels, thin-film panels are made from a variety of materials. The most prevalent type of thin-film solar panel is made from cadmium telluride (CdTe). Thin-film solar panels can also be made from amorphous silicon (a-Si), which is similar to the composition of monocrystalline and polycrystalline panels.

All of these types of solar power panels will help power your boat regardless of the type. Just make sure to calculate how much wattage you need before purchasing any of them.

How Do I Install Solar Panels On My Sailboat (With Videos)

This section is a collection of videos of people installing solar panels on their sailboats. I am a Patreon of a few of them and I definitely recommend following them on YouTube! There are so many different ways to install a solar panel, so I wanted to get a list of different ways and let you decide which way will work best for you. Enjoy!

As I said earlier in this section, there are a million different ways to install a solar panel. Each boat is different and you need to plan out what will work best for you and your boat.

In Conclusion

This article discussed the 10 best solar panels for a boat and where to purchase them from. There are a lot more options out there but these 10 are a great starting point. The three different types of solar panels mentioned were Monocrystalline Solar Panels, Polycrystalline Solar Panels, and Thin Film Solar Panels. All of these will work for charging boat batteries and electronics.

The last section of this article is a collection of solar panel installation videos. I am a follower of most of these channels and I definitely recommend you follow them as well for more helpful videos.

I hope this article helped with your solar panel search! Cheers!
