Bifacial solar panels are generally more expensive than traditional monofacial solar panels. On average, bifacial panels cost about 10 to 20 cents more per watt than monofacial panels, which can translate to approximately $600 to $1,200 extra for a typical 6 kW residential solar system. In larger utility-scale projects, the cost premium for bifacial panels tends to be lower, around 1 to 5 cents more per watt.
The higher cost of bifacial panels is offset by their greater energy generation capability. They can yield 6% to 10% more energy compared to traditional monofacial PERC technology panels, absorbing sunlight on both front and rear sides, which boosts overall efficiency (sometimes up to about 30% in optimal conditions, versus 15-20% for monofacial panels). This enhanced performance can make bifacial panels more cost-effective over their lifetime despite the higher upfront price.
In summary:
| Feature | Bifacial Solar Panels | Traditional (Monofacial) Panels |
|---|---|---|
| Cost per watt | 10–20 cents higher (residential) | Lower cost per watt |
| Typical system cost | $600-$1,200 more for 6 kW system | Lower overall upfront installation cost |
| Energy yield increase | 6%–10% higher than monofacial | Baseline energy production |
| Efficiency | Up to ~30% in ideal conditions | ~15-20% |
Bifacial panels may also benefit from tariff exemptions in the U.S., potentially reducing their cost disadvantage compared to imported traditional panels. Moreover, prices for bifacial panels are expected to decrease further, with forecasts suggesting a 23% drop in the coming years, which might narrow the cost gap.
Therefore, while bifacial solar panels are currently more expensive than traditional ones, their improved energy production and potential long-term savings can justify the additional initial investment.
