Things to Consider When Choosing Best Marine Solar Panels

When buying products like digital ballasts and other related items, you need to know some buying tips to help you choose wisely. The same case applies when you are buying a marine solar panel. We have provided you with some essential tips that will help you choose the right product that meets your needs.

Voltage Rating

​Compare the voltage at the open circuit to the voltage at the maximum power. Choose the panel with higher voltages at maximum and open power (Voc., Vmp.). This will be helpful to your system as the high temperatures result in a drop in the voltage.

Check the output specifications

During manufacture, the solar panels are put stickers, which indicate their performance at standardized testing conditions (STC). These specifications are related to the temperature in the panel and the angle in which the sun rays reach it. In areas where there are extremely cold temperatures, the temperature of the panel tends to go beyond the STC. There might be cases when the panel loses voltage in output and increases in temperature. All you need to do is to maximize the wattage for the available space.

Junction boxes

Ensure that before you purchase a solar panel, you check on its junction boxes’ condition. The best solar panels have junction boxes with an IP67 or IP65 waterproof ratings. IP ratings refer to the environmental protection that a product has gained from particles and liquids. For deck or rail- mounted panels, IP67 works the best while IP65 works best on panels mounted on the arch.

Consider the panel efficiency rating

Panel efficiency rating is the comparison of size against the power generation ability. You need to choose the panels with high-efficiency rating if your sailboat or motorboat has limited space. The size of the solar panel should be proportional to the amount of power it produces. This will keep your boat in the required condition.

Choose good quality panels

There are two major types of solar panels that are good for marine use, namely; Monocrystalline and polycrystalline. Monocrystalline panels are made from high-quality pure silicon and produce power in a range between (15-24%). They work best in shaded conditions and in high temperatures, too, making them more efficient for use. Polycrystalline panels are made from multiple smaller silicon crystals. They produce power in a range between (12-16%), making them less efficient. Silicon in solar panels has impurities that help it improve its ability to capture the energy from the sun and convert it into electricity. It is used in its crystalline state, which is also called ‘solar grade silicon’.

Price

Monocrystalline panels are of a higher price when compared to polycrystalline panels. This is because of its high power production and its silicon composition. You need, therefore, to be sure of the panel to use, depending on your boat’s mounting space. Highly-priced goods have efficiency in use and offer quality services. Budget wisely before you conclude on the type of panel to buy. This will prevent you from incurring losses, and it will make you produce more energy with less.
