Solar LCOE Calculator

Calculate discounted lifetime solar project cost per kWh from capital cost, production, degradation, operating cost, replacement cost, and discount rate.

Solar LCOE Calculator

Enter project costs, year-one production, degradation, operating costs, replacement costs, project life, and discount rate to calculate discounted lifetime cost per kWh.

Project assumptions

Enter costs and production

Use project-specific values. Incentives are optional and can be set to zero.

Method used

Present value of lifetime project costs divided by present value of lifetime energy. Annual energy is reduced by the degradation rate; O&M and replacement costs are discounted to year zero.

Planning estimate only. Results depend entirely on the assumptions entered and do not constitute engineering, tax, investment, or financing advice.
