Three main panel types exist. We use exactly one, for a specific reason.
Monocrystalline panels are cut from a single silicon crystal — highest efficiency (20-22%), longest lifespan, best heat tolerance. Polycrystalline uses multiple crystal fragments — cheaper upfront, lower efficiency (15-17%), shorter effective lifespan. Thin-film is flexible and lightweight but the least efficient of the three, mainly suited to specialty applications rather than rooftop homes.
For Ghana's heat and the roof-space constraints most homes face, monocrystalline consistently wins on real-world performance despite the higher sticker price — which is why it's the only type we install.
Since it's the panel type that wins on real-world performance, it's what every package includes.
