Solar technoeconomic analysis.

CEHelios is a technoeconomic analysis tool for solar projects. Move from array layout to levelised cost in a single model — module and inverter selection, full energy yield with soiling and clipping, capex and opex build-ups, financing structures, and revenue under multiple price and curtailment scenarios. Revenue scenarios pull directly from CEGridSight and CompoundVision rather than a flat hub-price assumption.

What it does

Three pillars.

01

Energy yield

Module, inverter, and tracker configuration with a full loss waterfall — soiling, thermal, mismatch, clipping, availability, curtailment — to net AEP and P50/P75/P90 distributions.

02

Capex, opex, financing

Bottom-up cost build-ups by component and balance-of-plant, with debt sizing, DSCR covenants, tax equity, and merchant-tail assumptions all transparent in the model.

03

Revenue scenarios

Plug in PPA, hub price, basis, and curtailment paths to get LCOE, IRR, NPV, and payback under each scenario — side-by-side, with the deltas attributable to each driver.

Status

In active build.

CEHelios is in active build, slated for integration into the CEAtlas Expert tier. Customers on early access are paired with the engineering team during build for spec and validation review.
