Stay informed about the latest developments in skid-mounted PV systems, prefabricated photovoltaic containers, containerized energy solutions, and renewable energy innovations across Africa.
Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.
These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Read more to find out how these cost benchmarks are modeled and download the data and cost modeling program below.
The cost of utility-scale solar in 2022 was down 84% from 2010. Solar power purchase agreements in the West were an average of $10/MWh lower than in other regions. Larger utility-scale solar projects (20 MW+) cost 26% less per MW than projects between 5-20 MW. Annual Energy Outlook, 2023.
Projected change in price by fuel type, 2022-2050 Solar, wind, and hydropower are based on the projected levelized cost of energy, which includes capital expenditures and operating costs, while natural gas, coal, and nuclear are based on the projected cost of only the heat content of these plants.
The cost to replace a solar inverter averages from $350 to $3,500 and depends on the type and number of inverters. Replacing a single microinverter costs less than replacing a string inverter. Expect to pay $200 to $500 for the labor, plus the cost of the inverter (or inverters).
Medium Residential Systems (6-10 kW): You’ll likely need an inverter between 6 and 10 kW, with costs between $1,800 and $3,500. Large Residential/Small Commercial Systems (10+ kW): These require inverters 10 kW and above, with prices starting around $3,000 and going up significantly depending on the specific application.
Countries like the USA, Germany, and India have introduced financial assistance programs that reduce the overall cost of solar power systems, making solar inverters more affordable for homeowners and businesses. Solar Inverter Price Comparison: What to Expect?
SolarEdge inverter costs in 2025 range from $1,367 for basic residential models to over $6,500 for commercial systems, but the total system investment including optimizers and installation typically runs $5,500-$9,000 for residential applications.
