Solar project economics, from array layout to levelised cost

Yield, costs and revenue for a solar project

• Yield runs from module, inverter and tracker configuration through soiling, thermal, mismatch, clipping and availability losses to net AEP, with P50, P75 and P90 distributions. The Perez transposition, cell-temperature and clipping models are the ones CompoundVision runs on the operating fleet, and 86 years of hourly irradiance from the CEAtlas store give the inter-annual spread.
• Capex and opex are built bottom-up by component and balance of plant, with debt sizing, DSCR covenants and tax structures.
• Revenue scenarios cover PPA, hub, basis and curtailment paths, priced with hourly zonal prices from CEGridSight so capture rates reflect the market the project will operate in. LCOE, IRR, NPV and payback sit side by side, with the effect of each driver attributed.
