Things to Consider When Buying Boat Solar Panels
These are some of the most important characteristics to consider when buying solar panels for your boat.
Amp Draw
Product information will help you know its power output. Sum up all your power requirements in a day then use this information to match up the kind of panel you want to buy.
Actual Output vs. Maximum Output
Whatever is advertised on the solar panel is the maximum output on a perfectly sunny day. Depending on the kind of area you are sailing, what are weather conditions? Will the solar panel be perfect for the zone?
The power output can drop influenced by wind, rain, or clouds. Will the output on such a day be favorable to you?
Will you be able to operate normally low power? Make your decision wisely when buying and installing alternative energy.
Climate Changes
It will not always be sunny. Plan for climate change and how to cope so that your work is not affected by the changes. This is a thorough guide on how solar panels work in weather conditions.
Panel Size
Your boat will determine the size of a solar panel you require, inclusive of the types of equipment you have in the boat. Take your time to research and know the amount of power sufficient for your boat.
It could be big (solar panel) with a low output. A big boat needs a solar panel that is powerful enough to power it efficiently.
Get a solar panel that fits your boat needs and also the dimensions of your boat.
Mono- And Multi-Crystalline
Solar panels made from a polycrystalline material are more expensive, but they are long-lasting, with good power output. These are some of the most important differences between monocrystalline and polycrystalline solar panels.
Amorphous Thin Slim Silicone
They are flexible to fit in curved spaces. They are cheap and less efficient compared to crystalline panels.
Cost
A sailboat needs good power to function without incidences. A good solar panel can be expensive. One or two panels are enough to power a big boat with a number of items on the boat that are constantly in use.
Guide to Buying The Right Solar Panel For Your Boat or Sailboat
How much energy do you need? Don’t just march to the market and purchase boat-solar panels because you need one. You need solar panels that serve you efficiently.
If you need a lot of power output, you cannot buy a small solar panel as it will not serve the purpose. Know well the amount of energy you need in a day and get your Sailboat a solar panel that will supply it with power sufficiently.
Solar Energy or Engine? Of the two, which one will you use most? If you choose solar energy over the engine, then you have to install powerful panels that are big enough to power your boat.
Again, if you decide to use both, you don’t need a big or powerful solar panel. If you are sailing in a windy zone, you can switch off your engine and take advantage.
How to Hook Up Solar Panels to A Boat Battery
