The US is about to get its first solar-covered canal
In general, Lepley said the capital cost for canal solar is roughly double that of land-based solar due to the cost of steel and foundations needed to support the PV panels above a canal.

In December, Interior announced it would install solar panels over the Casa Blanca Canal south of Phoenix, which serves the Gila River Indian Community, at a cost of $5.65 million.

Solar panels over canals can be a cost-effective solution. Utilizing existing water infrastructure eliminates the need for additional land acquisition. Additionally, the reduced water evaporation leads to cost
DeJong estimates that mounting solar panels over the canal is 33–40% more expensive than doing so on land, but he argues that the economic and social benefits of water, energy, and
Solar Installed System Cost Analysis NLR analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale
Solar canals cost more per panel than simple ground arrays because they need stronger supports, engineering, and special access for maintenance. Upfront costs include civil works, anchors, and
The $20 million experiment, dubbed Project Nexus, is funded by the state of California and will assess whether solar panel canopies erected over exposed irrigation canal systems can significantly reduce
Solar on canals has long been discussed as a two-for-one solution in California, where affordable land for energy development is as scarce as water. But the grand idea was still a
Discover the average solar panel installation cost, key price factors, and expert tips to help you budget for your solar project.
Project Nexus is billing itself as the first-ever example of solar panels on a canal in the US, with ground-breaking initially scheduled to begin this fall and completion expected next year.
