Quick Summary
Rooftop solar systems use monocrystalline, polycrystalline, or thin-film cell structures. Monocrystalline is the industry standard for residential roofs due to its superior efficiency, while polycrystalline is budget-friendly but less efficient.
Choosing the right solar cell type affects your system size, roof footprint, and overall project cost. Here is a high-level comparison of the three primary technologies:
| Technology | Efficiency | Aesthetics | Typical Cost |
|---|---|---|---|
| Monocrystalline | 19% – 23% | Premium Black | Premium ($$$) |
| Polycrystalline | 15% – 18% | Speckled Blue | Moderate ($$) |
| Thin-Film | 10% – 13% | Smooth Grey | Budget ($) |
Frequently Asked Questions
Which panel technology is best for homes?
Monocrystalline panels are the gold standard for residential solar because they pack the most power into a limited rooftop area.
