Why Solar Panel Prices Keep Dropping
Over the past decade, rooftop solar photovoltaic (PV) panel prices have fallen by 82%, making solar energy more accessible than ever. The average cost per watt in 2023 stands at $2.86-$3.48 for residential systems, down from $8.50 in 2009. But what's driving this solar revolution?
Key Price Reduction Drivers
- Improved manufacturing efficiency (30% increase since 2018)
- Thin-film technology advancements
- Global supply chain optimization
- Government incentives and tax credits
2023 Solar Panel Price Comparison
| Panel Type | Efficiency | Price/Watt | Best Use Case |
|---|---|---|---|
| Monocrystalline | 20-23% | $3.00-$3.50 | Limited roof space |
| Polycrystalline | 15-17% | $2.70-$3.20 | Large-scale installations |
| Thin-Film | 10-13% | $2.20-$2.80 | Commercial buildings |
Real-World Savings: California Case Study
The Johnson family in San Diego installed a 7.5kW system in 2022:
