Solar Panels for Boats Buying Guide

We have compiled a detailed buying guide to help you pick a suitable product. It will give you an idea about your requirements for solar panels for boats. 

  • 1 What to Consider When Buying Solar Panels? 
  • 2 How Do Solar Panels for Boats Work? 
  • 3 What Are Care Requirements to Enhance the Life of Solar Panels for Boats? 
  • 4 What Are the Properties of Charge Controllers for Solar Panels for Boats? 
  • 5 Conclusion 

What to Consider When Buying Solar Panels? 

Since solar panels are an expensive addition to your asset list, here are a couple of essentials to remember when purchasing. 

Size 

The size of panels is directly related to the size of your boat. You must get something to match the energy requirements of your boat or greater. A solar panel too small might not power it and leave you frustrated. Other than this, smaller products have less battery time which means they will turn off much quicker than something explicitly designed for the size of your boat. 

Type 

From PVC to glass covering and fully flexible panels, the type you choose determines their cost. This helps you establish your budget according to your needs. A glass-fronted solar panel is among the most budget-friendly options, but they are not as weather resistant. Besides this, a polycarbonate version is more expensive, but they are incredibly weather resistant and have a longer life. 

Accessories 

A charge controller or maintainer is an essential component available for your boat’s solar panels. This product protects your panels from battery damage. They prevent any risk of overheating, battery discharge, or sudden drops. A charge controller is essential if you want to elongate the battery’s life. Most brands also offer mount brackets, so you don’t have to purchase them separately. 

How Do Solar Panels for Boats Work? 

Solar panels for boats work just like any other portable energy provider. To install it successfully, you must have four components: the solar panel itself, charge controller, inverter, and battery. When solar panels in the boat hit sunlight, they convert it into the electrical current, supplying your boat with the required energy. 

Boat solar panels can work without a charger maintainer (controller), but there is a risk of overcharging your device. Therefore, you must keep it in place to avoid any risk of battery damage. 

The need for an inverter depends on the number of appliances that need a charge. For instance, if you wish to charge multiple devices other than the boat, consider buying a large-capacity product. 

You can opt for professional installation if offered by the brand or any other reputed company. But individuals who have the basics can do it all by themselves. However, you must make sure that all the relevant accessories are available at your convenience. 

Installation

The installation method is divided into three main stages. The first stage is to conduct an energy assessment. In this, you will determine the level of energy that your boat needs to function. Buy a panel that has a higher voltage than your requirements. This gives more room and flexibility to charge other devices. 

Check whether the solar panel can produce that level of energy. Once the capacity is determined, you can decide the exterior of your panels. In most cases, you choose between glass-fronted, polycarbonate, and fully flexible panels. 

What Are Care Requirements to Enhance the Life of Solar Panels for Boats? 

Caring for solar panels is essential as they are a long-term investment and should last accordingly.

Use life

Most solar panels are designed to last two to three decades. Caring for them is fairly simple but requires regular attention. All you have to do is keep them clean from dirt, leaves, and other obstructions. Solar panels from reputable brands always come with a warranty for a couple of years. 

Always get a professional repair from the brand in case of any damage. Even if your warranty has expired, we recommend taking your boat’s solar panels to a professional. They might cost a bit more than a local mechanic, but your panels get the treatment they require. 

Another factor to consider here is the useful life of your solar panel. This indicates that they will not be as effective as they age. The depreciation in their quality is slow and gradual. 

If your product has met the end of its useful life, it won’t stop working but will get more prone to damage. So instead of getting frustrated with why your solar panel for boats isn’t working properly, consider getting a replacement from the same brand or changing your product. 

Cleaning 

To clean a solar panel, use lukewarm water with a mild, non-acidic detergent and apply water pressure to remove any visible dirt and debris. Panels for boats are relatively smaller, so you won’t need a lot of supply. Clean any unwanted spots with a damp cloth and leave it to dry. Avoid applying water pressure on smaller models as they might not sustain the burden.

What Are the Properties of Charge Controllers for Solar Panels for Boats? 

Charge controllers are an essential component. They help protect your panels’ battery from damage. There are three main types of charge controllers available. 

Basic charge controllers 

They use pulse width modulation to encode transmission information allowing control of the power supplied to boats or other devices. These are simple chargers that come in at an affordable price range. A primary charge controller is designed to control batteries of smaller solar panels. They might not deliver desirable results if connected with a high-capacity panel. 

Mid-range charge controllers

These controllers also use pulse width modulation but feature an LCD display to indicate current charging levels. This helps the user keep track of the system and unplug the device when it’s ready to use. 

Max power charge controllers 

Designed for high-end and powerful solar panels, they are one of the most expensive charge controllers. You should only attach them to devices recommended by the brand itself. They also maximize the performance of panels. 

Conclusion 

Solar panels are a great way to maximize energy efficiency in your boat and create a durable backup. They are available in different sizes and capacities, so you can find a suitable fit for your boat. This article carefully reviewed the most in-demand solar panels for boats in 2023 that can make a difference in your overall experience. Besides the panel, you should also grab a top-notch charge controller that protects the device from damage and enhances its life.
