PRICE PER WATT OF SOLAR PANELS DROPS
The Price Of Solar: 1997: $76.67 per watt
This year saw the price of photovoltaic cells for solar panels continue its dramatic slide downward, reaching $0.74 per watt. That’s a 99 percent drop over the last 25 years, bringing solar to near-parity with the rest of the grid. Decades of support from state and federal governments around the world in the form of R&D, purchases, renewable energy standards, and subsidies played a large role in making such a significant drop possible. The level solar PV power in Germany has been increasing exponentially for the last 20 years, with a doubling time of 1.56 years.
