Do engineering technologies affect the cost of photovoltaic systems?
This work builds on mathematical models that the researchers previously developed that tease out the effects of engineering technologies on the cost of photovoltaic (PV) modules and systems. In this study, the researchers aimed to dig even deeper into the scientific advances that drove those cost declines.
How do market analysts evaluate the cost of PV systems?
Market analysts routinely monitor and report the average cost of PV systems and components, but more detail is needed to understand the impact of recent and future technology developments on cost. Consequently, benchmark systems in the utility-scale, commercial, and residential PV market sectors are evaluated each year.
Why are solar module prices so volatile in ?
Importation duties, oversupply, and supply chain costs have led to significant solar module pricing volatility, particularly since the start of . New technology is rapidly evolving improving efficiencies with the market seeking more clarity around the changing prices of solar modules.
What is NREL's PV cost benchmarking work?
NREL analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. This work has grown to include cost models for solar-plus-storage systems. NREL's PV cost benchmarking work uses a bottom-up approach.
Where did photovoltaic cost data come from?
Photovoltaic cost data between and has been taken from Nemet (), between and from Farmer & Lafond (), and since from IRENA. Prices from Nemet () and Farmer & Lafond () have been converted to US$ using the US GDP deflator, to account for the effects of inflation.
Why are solar energy systems declining?
A new study reveals key innovations that contributed to the rapid decline of solar energy systems, showing that many of the most significant technological advances came from outside the solar sector. This work could help businesses, researchers, and policymakers identify optimal areas for future investment.
