Adding Solar to your home is a major home improvement project that will add value to your home.   When considering Solar it's best if you educate yourself on the differences in technologies and don't shop on price alone.   

The two types of panels commonly used in rooftop solar are monocrystalline and polycrystalline solar cells.   The main differences are in their efficiency, appearance, and cost. Monocrystalline cells are more efficient and durable, but also more expensive, while polycrystalline cells are less efficient but more cost-effective.  

Monocrystalline solar cells are made from a single, pure crystal of silicon. They have a uniform black color and are highly efficient, with conversion rates of up to 22%. Monocrystalline cells are also more expensive to produce, perform better in low light conditions, and are known for their long lifespan and durability. 

Polycrystalline solar cells, on the other hand, are made from multiple crystals of silicon that are melted together. They have a speckled blue color and are less efficient than monocrystalline cells.   Polycrystalline cells are less expensive to produce, does not perform well in low light conditions and does not have the life expectancy of Monocrystalline panels. 

Considering Going Solar is a "25+ year Decision" Monocrystalline is really the only way to go.  By investing a little more now, Tier-1 Monocrystalline  Panels will generate more electricity using less space.
