Comparing Monocrystalline and Polycrystalline Solar Panels
They may cost a bit more per watt, but we think they’re worth every penny - and so do countless homeowners and contractors who have chosen monocrystalline over polycrystalline solar panels. Compare the two options side-by-side below:

Think about it like this - you get more efficiency out of every square inch of panel when you go with monocrystalline panels. That means you might still end up saving money in the end since you can get by with fewer panels. If nothing else, the investment pays for itself in lower labor costs and less racking hardware needed.
