U.S. solar LCOE on the rise, says Lazard

The levelized cost of energy (LCOE) for utility-scale solar PV has increased slightly year on year due to higher capital costs, interest rates, tariffs, and ongoing supply chain pressures, according to the 2026 Levelized Cost of Energy Report published by US-based financial firm Lazard. The report compares the LCOE of various electricity generation technologies on a dollar-per-megawatt-hour ($/MWh

How EPCs can de-risk solar carport projects

Some projects forgive mistakes. Carports do not. One wrong assumption about soil, one structural detail overlooked, one steel price swing between bid and build, one buried obstruction nobody flagged or knew about, and any one of those can wipe out a project’s margin. Together they can sink a company. Carports are one of the fastest growing and most misunderstood segments of commercial solar. Schoo
