Components of the best marine solar panels for sailboats
You would need four main components for your solar panel system, and they include the following:
- Battery
- Solar panels
- Inverter
- Charge controller
Solar panels
The solar panels can easily absorb energy directly from the sun and convert it into electricity.
Some panels can work in cloudy weather. When the sun is full, these solar panels work excellent.
You should learn how to align your solar panels towards the sun.
Charge controllers
With the charger controller, the batteries are prevented from overcharging. You can use it to regulate your power input.
It helps in offering optimal power output.
Inverter
Inverter helps in the conversion of direct current (DC) electricity into alternating current (AC) electricity.
We have numerous equipment and appliances using AC power. This means that the inverters are important in solar power energy systems.
Batteries
You need batteries to story energy from the best marine solar panels for sailboats. The lead-acid deep-cycle batteries work best for solar power.
You should not allow your battery to discharge below 50% if you want to maximize the number of future charge or discharge cycles.
Connecting cables are required to connect everything, alongside optimal brackets for the installation of the panels.
This would help in directing it towards the sun.
How to get the most out of the best marine solar panels for sailboats
Avoid shadows
The solar panels should stay away from shadows. You do not have to assume that the small shadow would be nothing on your panels.
It could affect its output. Ensure that the boom, radar scanner, and mast do not cast shadows that would hit your panels.
The direction of the sun
You should make sure that the panels face the sun. If you want the solar panels to produce more power, it has been directed towards the sun.
You generate less power if the panels are not well aligned towards the sun. You should learn how to achieve procedure when buying any of the solar panels.
Ventilation
If you have solar panels, they should be ventilated. In the sun, solar panels will get very hot or high temperatures.
These two factors could affect the efficiency of the solar panels. Make sure that the panels have nice ventilations.
They should not be kept where the air is limited. Consider the right place to position your panels.
INTENSITY (% OF FULL SUN) POWER OUTPUT
- Full Sun – Panel pointed directly at sun 95-100%
- Full Sun – Panel at 45° angle to sun 60-70%
- Light overcast 50-80%
- Heavy overcast 10-30%
- Indoor light 3%
Before you purchase any of the best marine solar panels for sailboats, you should ensure that it suits your needs.
