What’s the difference between monocrystalline vs. polycrystalline solar panels?
The two main types of solar panels are monocrystalline and polycrystalline panels.
Polycrystalline panels, which are light blue in color, are less energy and space efficient than monocrystalline panels, but they are also the cheaper option. Monocrystalline panels, which are darker in color, are more energy efficient. Monocrystalline panels are more expensive, but if efficiency is a driving factor for your solar decisions, they’re a great product.
Should I use 12v or 24v panels?
Panels can also typically come in either 12V and 24V options. Most motorhomes and boats have 12V battery banks already installed, so it is wise to stick with 12V panels to be compatible with those existing systems. We recommend 24v panels if you’re installing a larger installation on a home or off-grid cabin.
Should I purchase portable or roof-mounted panels?
Portable solar panel systems are a lightweight and versatile solar solution that’s particularly appealing to those who are new to solar. Instead of having to mount panels to a roof, portable solar panels are typically available as folding suitcase panel kitsthat can easily be set up and angled on the ground. Roof-mounted panels are ideal for those who have steady energy needs and want to be able to charge their batteries or devices when they’re not around. Roof mounted panels are available as traditional rigid panels or flexible panels that can be mounted on non-horizontal surfaces.
How many solar panels do I need?
It’s incredibly important to properly size your solar installation, especially if you’re going off-grid and are relying solely on your solar panels. To determine what size system will best fit your needs, we recommend using the Renogy solar panel calculator. Our solar sizing calculator allows you to input information about your lifestyle and appliances and devices used to help you decide on the right number of solar panels to install for your system.
