When it comes to actually collecting energy from the sun, that’s where solar panels come in. There are a few different solar panel options available to choose from.

Mono-crystalline vs. Polycrystalline Panels

Choosing between mono-crystalline and polycrystalline panels is one of the first steps to take when shopping for solar panels. Polycrystalline panels are light blue in color, and they are less energy and space efficient than mono-crystalline panels. On the plus side, they are also the cheaper option. Mono-crystalline panels, which are darker in color, are more space and energy efficient. Keep in mind that with the added efficiency comes with a higher price tag.

Portable vs. Roof Mounted Panels

Rigid, roof mounted solar panels are the most common solar panel type and durable solar panel type. They are also ideal if you have consistent energy needs and want to be able to charge your battery bank at the flip of a switch. If you are looking to mount your solar panels on a non-flat roof, flexible solar panels are the way to go.

On the other hand, portable solar panels are perfect for those who may not be ready to mount solar panels on their roof, have limited surface area to mount panels, want to generate solar on multiple applications, such as on your RV and your home, or have smaller energy needs. One of the most popular types of portable solar panel systems are folding suitcase panel kits. Folding suitcase panel kits are lightweight, easy to handle, and can be set up on the ground and angled for maximum efficiency.

12V vs. 24V Panels

Solar installations are built out as 12, 24, or 48 volt systems. Most RV’s and boats have 12V battery banks, so people usually stick with the 12V panels in order to be compatible with those. You may consider a 24v solar panel system if you have high energy needs. If your energy needs are about 1 to 3 kW, we’d recommend a 24 volt system. If your energy needs are above that, you’ll want to install a 48v system. Having a higher voltage panel system can save you money in the long run as you need less charge controllers and can use thinner cables for the same amount of power.

Solar panels are also available in flexible and rigid forms. Flexible panels weigh less than the rigid solar panels and can be installed directly on the roof of your RV or van. Rigid panels, which are more typically durable, can also, be mounted to tilt, which makes their solar energy collection more efficient. If you’ll be mounting panels to your roof, you’ll want to take into consideration the condition of your roof and how old it is. If it’s nearing the end of its life, you’ll want to replace it before going solar.
