Q/A

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

    There are two main solar panel types: monocrystalline and polycrystalline panels. Polycrystalline panels, which are light blue in color, are less efficient than monocrystalline panels, but they are also cheaper. Monocrystalline panels, which are darker in color, are more space-efficient. Monocrystalline panels are more expensive, but if efficiency is a main factor, they’re a great product.

  • Should I purchase portable or roof mounted panels?

    Portable solar panel systems give you the ability to generate and store your own electricity using portable solar panels, charge controllers, batteries, and inverters. Instead of mounting to a roof, portable solar panels come in different forms and are often available as folding suitcase panel kits that can be set up on the ground or flexible panels that can be mounted or hung from your vehicle or other vertical surfaces. Portable solar panel kits 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.

  • Should I use 12v or 24v panels?

    Panels typically come in either 12V and 24V options. Solar panels can be wired in series or in parallel to increase voltage or current, respectively. Most RV’s and boats have 12V battery banks, so people usually stick with the 12V panels in order to be compatible with those. 24v panels are great for larger installations to meet higher energy needs, such as on a home or off-grid cabin.

  • How do I know what size system I need?

    To determine what size system will best fit your needs, make a list of all the appliances and devices you plan on running. The main appliances to take into consideration when addressing energy needs may include a TV, lighting, water pump, laptop, fans, microwave, and refrigerator. We recommend using the Renogy solar panel calculator to help determine your specific needs. You’ll just need to know what total watts your electronics will consume, how long you plan on running devices, your charge controller efficiency, and average sun hours per day.
