How to choose the right solar panels for your boat
To choose the right solar panels for your boat, you must determine how much power your boat uses. The first step is to determine how many amp hours your appliances use daily.
You can use a battery monitor to measure the energy your fridge, lights, or the other appliances on your boat consume while in use.
After finding the amp hours your boat uses per day, you can determine the wattage of power your solar panels need to produce. For example, if you have a 50-watt panel and use 30 amp hours per day, you would need two 50-watt panels to produce enough power for your needs.
Additional things to consider are whether you need a charge controller and if you have enough unshaded space for your solar panels to absorb the maximum amount of sunlight.
What are Flexible and Rigid Solar Panels?
Rigid solar panels are more efficient but less robust than flexible panels. Monocrystalline cells offer a better output than polycrystalline cells. The output voltage depends on the number of cells on the panel.
Module efficiency is now more often around the 20% mark, as opposed to 12-15% for older models and semi-flexible (up to 20° bend) is usually better than flexible (up to 180° bend).
If the maker offers a 25-year guarantee instead of a 3-5 year one, you can be pretty confident they’re good. Regarding charge controllers, it’s worth paying a little more for a decent MPPT.
How many solar panels do I need for my sailboat?
You will need between 2-8 solar panels for your sailboat. The amount you need depends on the size of your sailboat and how many electronics you need to power. 2-4 panels should be enough if you have a small sailboat. For larger boats with more electronics, 4-8 panels are recommended.
