Solar panels

Every year, more and more yachtsmen want to install solar panels on their multihulls. And they’re right to do so: photovoltaic energy is natural and clean, and above all, it enables them to be self-sufficient during long crossings and at anchor. The result of this craze for solar energy - on land and at sea, in fact - is an explosion in the market, accompanied by a wide range of products. Many boat builders are now integrating custom solar panels into the superstructures of their models.
Before starting your installation, it’s a good idea to give careful thought to your project, and in particular to the power you’ll need and the location of these solar panels. And be aware that not all technologies are created equal. Here are a few important points to consider.

Two main technologies

Solar panel technology is evolving rapidly, and today there are two main kinds of solar panel on the market: monocrystalline and polycrystalline. These two technologies offer distinct advantages and disadvantages, depending on the specific needs and constraints of each project.

Polycrystalline technology, a budget friendly choice
Polycrystalline solar panels are made from solar cells composed of several silicon crystals, making them relatively inexpensive to produce. While polycrystalline panels are not the most efficient, they do offer a good compromise between performance and cost. Polycrystalline solar panels are also considered relatively durable, with little risk of breakage or degradation over time.

Monocrystalline technology for greater efficiency
Monocrystalline solar panels are made from pure silicon solar cells, giving them high energy efficiency. In fact, monocrystalline panels are significantly more efficient than polycrystalline panels, which means they can produce more electricity per square meter of surface area. The resulting truism is that these panels take up less surface area for the same power output. What’s more, monocrystalline solar panels perform better for longer, and charge better when sunlight is low. On the other hand, they are slightly more expensive than polycrystalline panels.

A choice dictated by space and budget
The choice between monocrystalline and polycrystalline solar panels depends on your needs and your budget. If space is limited and your budget allows, monocrystalline solar panels are the best option, as they offer better performance for a smaller surface area. On the other hand, if cost is a determining factor, polycrystalline solar panels can be an effective alternative with good value for money.

Flexible or rigid solar panels?

Today’s solar panels are available in rigid or flexible form and look very different indeed. So, what are the advantages and disadvantages of each type of solar panel?
The first criterion for deciding between a flexible or rigid panel is, of course, where the panel is going to be installed. If you don’t have a flat surface, the choice is quickly made. If you do, it’s up to you to weigh up ...
