Monocrystalline vs. Polycrystalline Panels: Which Is Right for You?
Choosing between monocrystalline and polycrystalline panels is one of the most common decisions Tucson homeowners face when planning a solar project. Both options have real trade-offs in cost, lifespan, and day-to-day use — and the right pick depends on your property, your budget, and how long you plan to stay in the home. This guide breaks the decision down in plain language so you can walk into a consultation knowing exactly what to ask.
Quick Comparison
| Factor | Monocrystalline | Polycrystalline Panels |
|---|---|---|
| Efficiency | 20–23%, best in class | 15–18% |
| Space | Fewer panels for same output | Needs ~10% more roof |
| Heat | Handles heat better | Loses more output when hot |
| Cost | $2.80–$3.50 per watt | $2.40–$3.00 per watt |
Choose Monocrystalline If…
you have limited roof space or a hot climate. Skip it if your situation is closer to the polycrystalline panels side of the table above.
Choose Polycrystalline Panels If…
you have plenty of roof and want the cheapest panels. Skip it if monocrystalline fits the criteria on the other side.
