What’s the difference between monocrystalline vs. polycrystalline solar panels?

When shopping for solar panels, you’ll see there are two main types of solar panels: monocrystalline and polycrystalline panels. The dark grey panels, known as monocrystalline panels, are more space-efficient and advanced, but they’re also more expensive. 

Polycrystalline panels, which are light blue in color, are less efficient than monocrystalline panels, but they are also cheaper.


Should I purchase portable or roof-mounted panels? 

Roof-mounted panels are more traditional and what many people typically think of when they envision solar panels, but more and more people are choosing to purchase portable solar panels for their ease-of-use. Portable solar panel systems give you the ability to generate and store your own electricity using lightweight and compact solar panels. They can be a great solution for those not ready to install a solar system on their roof, have limited space, or who have smaller energy needs. Portable solar panels are available as folding suitcase panel kits that can be set up on the ground and angled for maximum efficiency. If you have consistent and larger energy needs, roof-mounted panels are typically the way to go. Rigid panels are the classic route to go for many individuals, but flexible panels are great when you’d like to mount your panels on a non-horizontal surface, such as the curved roof of a caravan.


How do I maintain my solar panels? 

One of the benefits of solar energy is how little maintenance solar panels require. We encourage you to visually examine the panels at least once a year to make sure all connections are still in place and in working order. We also recommend washing the panels off at least once a year to clean off any residue or dirt that has collected on the panels. 


How do I know what size system I need?

To determine how many solar panels you should install in your system, we recommend making a list of all the appliances and devices you plan on running and how much energy they draw.  The Renogy solar panel calculator is an easy-to-use tool that helps you determine your specific needs.
