Monocrystalline Solar Panels
The most common and most efficient residential panels. Monocrystalline modules pack more output into less roof space and hold value well, which is why most quality installs use them; you pay a little more per watt for it.
Lifespan: 25–30 years
Polycrystalline Solar Panels
A lower-cost panel that trades some efficiency for price. Polycrystalline modules need more roof area for the same output and are less common in new installs, but can make sense on large, unshaded roofs where space is not tight.
Lifespan: 25 years
Bottom line: Polycrystalline Solar Panels wins on upfront price; Monocrystalline Solar Panels wins on longevity or capability. The right pick depends on your budget and plans.
