The 2022 Photo voltaic Technology Index report exhibits that the efficiency of photo voltaic property is decrease than estimated.

kWh Analytics, a local weather insurance coverage firm, states in its 2022 Photo voltaic Technology Index that photo voltaic property are broadly performing under expectations. The report incorporates information from trade collaborators and Heliostat’s proprietary kWh Analytics database.
On common, tasks constructed after 2015 generated 7% to 13% much less electrical energy than the P50 manufacturing estimate. P50 means that there’s a 50% probability in any given yr that manufacturing will likely be at the very least a specific amount. If an array has a P50 manufacturing degree of 500 kWh, because of this in any given yr there’s a 50% chance that the manufacturing will likely be at the very least 500 kWh.
The report concludes that because the hole between precise and anticipated technology grows, poor efficiency dangers jeopardizing investor returns and the trade’s means to realize sustainable development.
“The underperformance impacts buyers and lenders who’re important to the success and development of photo voltaic tasks,” stated Jason Kaminksy, chief government officer of kWh Analytics. “As an trade, we should work collectively to search out methods to right course to make sure the long-term monetary well being of the trade.”
The common efficiency of tasks constructed final yr represents a slight enchancment in comparison with 2020. Basically, tasks constructed since 2015 are worse than these constructed within the early a part of 2010 in comparison with their P50 approx.
The kWh Analytics report exhibits that since 2019, tasks with a capability of greater than 50 MW have carried out worse in comparison with their P50 estimate than tasks within the vary of 1 MW to 50 MW.
The underperformance pattern is a nationwide phenomenon, in response to kWh Analytics. Underneath 10 years of operational information, the common lifetime efficiency ranges from 5% to 10% under the preliminary P50 estimate within the seven areas. Over time, efficiency has continued to say no in each area. The one outliers in 2021 have been the Northwest and Southeast areas, which improved by 1% and a pair of%, respectively.
“It’s essential that we proceed to help the long-term success of the renewable power sector,” stated Kaminksy. “As a way to de-risk investments in zero-carbon property and encourage sustainability throughout the trade, sponsors and lenders ought to contemplate appropriately pricing danger switch merchandise, cautiously aggressively manufacturing forecasts, and work with stakeholders to encourage information sharing.”
The report additionally examines system efficiency based mostly on venture capacities and mount sorts. It didn’t discover any developments in poor efficiency remoted to any particular group of tasks.
