Marine panels are of great use when you need continuous power, without any fluctuation in the voltage. If we use marine batteries, we could get stuck in the long run, with no way of powering them. In this kind of situation, one needs solar power panels, for boats, as they’re a reliable source of electricity. The idea was brought into the existence in 1975, England. From that day, they have been an integral part of boat trips. These panels help in recycling the power in the battery, giving you maximum power and performance.

The panels can retain 80% of efficiency in 25 years period, having 5 years of manufacturing warranty. Your product gets replaced if anything happens.
How Does Marine Solar Panels Work?
Solar panels are a great invention, harnessing power from the ultimate source of energy, by simple steps. A solar panel consists of solar cells, a resting panel on which cells are placed, transparent sheet on the cells, transformer and a battery to store charge.
When the light falls on the solar cells, the electrons present in them, cross the potential barrier, by absorbing energy and flow through the circuit to complete the current path. The cells are made with n-type and p-type semiconductors, slightly doped as per requirements. Then the energy created by the solar cells travels to the transformer, which can amplify the voltage or current, giving, if it is a step up or step down type transformer. This helps in making the current constant, as the fluctuation of the current in the circuit can cause problems. Finally, the charge is stored in lithium-ion or acid charged batteries, for further use of the charge through them.
The quality and quantity of the power depend upon the solar cells, their area, type of weather conditions, and circuit of the solar panel. Together is tuned well, they can provide clean energy at very low cost.
Benefits Of Using Marine Solar Panels
- They’re a comparatively clean and silent form of energy providers. You can expect a peaceful form of energy. They don’t cause pollution and doesn’t eat up our money, as the sun is their resource for making the energy.
- They’re more durable than any of the electricity generator. The lifespan of a generator is 5-7 years, but in case of solar panels, you can expect 25 years of the unbreakable bond between the panel and battery.
- They have a very low maintenance cost than generators. Generators need engine oils, which needs to be replaced every once in a while. Mechanical parts are complex and need to get extra care. But solar panels are extremely durable, just a strong sheet of aluminum and that’s it. Due to fewer steps involved, they’re less complex and durable.
- Panels are easy to carry, whereas generators are heavy. Your boat may not like a generator on the board; however, having a solar panel is a different story.
- Solar panels have better performance and efficiency parameters. They don’t overcharge the battery and performance of the battery doesn’t suffer. They in fact, help in yielding better energy transfer rates.
How to Choose The Right Marine Solar Panels?
Solar panels are of great help to mankind but choosing the right one for the purpose is a difficult job. A best solar panel should have all the features required, in a perfect quantity to deliver maximum quality power without any fuss. Let’s choose a solar panel on the below-mentioned points
Solar Cell: There are mainly two types of solar cells that are used in the panels; mono-crystalline cell and amorphous cells. If you’re going for durability I would recommend you mono-crystalline cells, as the last 25 years long. But on the other hand, amorphous provide better reliability for power but lasts 5-7 years.
Power: Solar panels come in 50 and 100-watt variants. If you want to charge your battery fast, then go for 100 watts, but their size is also big, not recommended for small boats, else, go for 50 watts one.
Durability: If you want durability, then go for aluminum, strong and hard solar panels that can last for long period of time in adverse conditions.
Performance: Choose the solar panel which has better performance, good ampere per hour and low charging time ratings. This usually depends upon the type of cell and area.
