1. Average Cost Per Watt
According to the Solar Energy Industries Association, the average price per watt for residential solar projects in the first half of 2023 was $3.27. This figure represents a slight increase from the pre-pandemic low of $2.92 but is significantly lower than the $6.65 per watt price back in 2010.
2. Types of Solar Panels
The cost per watt can vary based on the type of solar panel you choose. Here are the three main types:
1. Monocrystalline Panels: These panels have the highest price point, typically around £1 per watt in the UK.
2. Polycrystalline Panels: A more affordable option, polycrystalline panels cost around £0.90 per watt and are commonly installed.
3. Thin-Film Panels: The least expensive choice, thin-film panels come in at approximately £0.80 per watt.
3. Factors Influencing Cost
Several factors impact the cost of solar panels:
- System Size: Larger systems tend to have a lower cost per watt. A fully installed 5 kW (5,000 Watt) solar system typically ranges from $15,000 to $25,000 before incentives.
- Sunlight Hours: The number of sunlight hours your location receives affects efficiency and overall savings.
- Roof Orientation: South-facing roofs maximize solar exposure.
4. Return on Investment
Investing in solar panels pays off over time. For instance, a 4 kW solar panel system in the UK costs around £5,000 - £6,000. With estimated yearly savings ranging from £440 to £1,005, you'll break even on your investment in about 8 years. Considering that solar panels last around 25 years, you'll enjoy free energy for more than half their lifetime.
Conclusion
Solar panel costs per watt have come a long way, making renewable energy an attractive option for homeowners. Whether you're passionate about sustainability or simply want to save on electricity bills, solar panels are a smart investment.
