Sailors can use solar panels for their energy needs, to run appliances or lights, even in cases when their generator is broken or when they don’t have enough energy in their batteries. Recharging batteries is much easier to do when using solar panels.

For a sailor, knowing how to install a solar panel in marine conditions can prove to be important, so it’s a skill worth knowing. You should also learn what solar panel works best in your situation. Usually, solar panels will use one of three main types of solar cells. Each of them comes with their own disadvantages and advantages.

Different Solar Panel Types

1. Monocrystalline cells will give you solar panels which are very efficient, while occupying a smaller space, but they don’t have protection against shade.

2. Polycrystalline cells will provide you with solar panels that are highly efficient, with even a smaller amount of space occupied, but still lacking shade protection.

3. If you get a solar panel that uses amorphous silicon cells, you will get a smaller efficiency in the conversion, with more space occupied, but at least you get the shade protection.

You will find both flexible and hard types of marine solar panels. You can use a hard solar panel on a deck. A solar panel that is flexible can be used either on a canvas or on a deck.

Solar Panels Number and Size

You will also need to be able to calculate the number of solar panels you should install on a boat, which is part of using marine solar panels. You can find on the Internet this information. You should install around 20% more solar panels, than what you estimate you will need to run your boat.

How You Should Place a Solar Panel

After you find out how many panels you need, and how big they should be, you should look for the place where you can install them. The panel’s size and the configuration of the boat determine where you can install the solar panels. You should read the solar panel instructions and make sure that the warranty isn’t cancelled by anything in the installation process.

The easy answer to the question of where should the solar panels be installed is in a place where they will get the most sun. The place that gets the less amount of shade and the most amount of sunlight is the perfect place to install your solar panels. When you install a solar panel, you should use braces/bars to make sure they are secured.

Even though solar panels are quite simple, they can still have problems from time to time. Here are some of the areas where they can have problems.

Out of all the ways that we can obtain renewable energy, a solar panel is our best bet for the future. It’s easy and it’s clean at the same time, even though it’s not the perfect method. Solar panels come with their own set of issues, both in the space/efficiency department and in the materials/cost area.

It costs quite a bit to install a solar panel, usually around $7 for each watt that your solar panel will provide. So, if you need 100 watts, it will cost you around $700 to install it. For a regular family, this cost will probably be too high. If you install them in a condo or an apartment complex, the cost increases, so solar panels are not enough.

You should also take into consideration the costs of the maintenance. The way to offset the installation costs is by using government incentives, like tax credits or rebates.

Glass and semiconductors are the main materials used for solar panels, and they are usually considered fragile. You need to maintain them and sometimes you also need to replace them. This happens even if you use Plexiglas shields for your solar panels, since they can still get deteriorated by hail, wind or lighting. When an area is prone to hurricanes, chances are that it’s not very practical to use solar panels, as they get damaged if you leave them up during bad weather.

One other problem you might have with panels is how efficient they are. Their efficiency ranges from 8 to just 15 percent, so you need more of them to produce all the energy you need. They also have problems if they don’t get direct sunlight, as it reduces their power output. Another factor that can cut down on the efficiency is if the house is at a good angle for the best amount of exposure, and they’re usually not. If you get long periods with bad weather, the solar panels become useless.

You can compensate for the efficiency problems by using solar arrays, but they tend to take a lot of space to set up. The latest prototypes of solar panels have efficiency of up to 40%, which should prove revolutionary once they get to the average consumer. You get a solar array by combining a number of different solar panels together, and creating a single big unit.
