future utility‐scale PV levelised cost of electricity
• BOS = everything except PV modules• Components: Structures, trackers, converters, cables, safety, grid
connection,…
• Installation: civil works, mechanical and electrical assembly,…
• Other costs to be considered for CAPEX:• Soft costs: engineering and system design, permitting, financing costs,…
• Other component associated to PV plants: Energy Storage Systems
Components and substructures (BOS)
• In France, for plants planned to be commissionned in 2020:• Average of 700, 800, 900, 1000€/kWp for 30, 15, 10 et 5 MWp
• CAPEX variation around average: +/- 20%
• Decrease of about 30% since 2017-2018
• In Germany, CAPEX ~10% lower• Estimation based on LCOE : similar LCOE with less production
CAPEX of utility-scale PV plants – France and Germany
• Based on 2018 data:• USA similar to Germany, 10% lower than France
• Italy, China, India: 10-15% lower than Germany, 20-25% lower than France
• In 2020, lowest CAPEX < 500/kWp for some places
• Could reach 250-350 €/kWp
CAPEX of utility-scale PV plants – other countries
Different from NREL estimation: 1,13€/Wp in 2018 Similar to Germany
VARTIAINEN ET AL
• Inverters: 50-70€/kWp in France• 30% lower in the USA BUT should be similar now 30€/kWp
• Electrical BOS: 80-220€/kWp in France• Similar in the USA
• Structures: 110-180€/kWp in France• 20-30% lower in the USA
Cost of components – utility-scale PV plants
• -40% since 2017-2018
Cost of inverters - evolutions
• CAPEX as low as 300€/kWh, all included, for 4-h ESS
• Could reach 100-150€/kWh in 2030
