Solar Energy Cost Formula:
| From: | To: |
The solar energy cost per kWh represents the levelized cost of electricity generated by a solar power system over its lifetime. It helps compare the cost-effectiveness of solar energy with traditional energy sources and other renewable options.
The calculator uses the simple formula:
Where:
Explanation: This calculation provides the average cost per unit of electricity produced, helping evaluate the economic viability of solar investments.
Details: Calculating solar energy cost per kWh is essential for financial planning, comparing energy options, assessing return on investment, and making informed decisions about solar energy adoption.
Tips: Enter the total system cost in your local currency and the estimated total kWh generation over the system's lifetime. Both values must be positive numbers for accurate calculation.
Q1: What costs should be included in total cost?
A: Include solar panels, inverters, mounting hardware, installation labor, permits, maintenance costs, and any financing costs over the system's lifetime.
Q2: How to estimate total kWh generated?
A: Multiply the system's rated capacity by the average daily sun hours, then by 365 days, and finally by the estimated system lifetime in years, considering degradation.
Q3: What is a good solar energy cost per kWh?
A: Typically, solar energy costs between $0.05-$0.15 per kWh, which is competitive with or lower than grid electricity in many regions.
Q4: How does system size affect cost per kWh?
A: Larger systems generally have lower cost per kWh due to economies of scale and better utilization of installation costs.
Q5: Should government incentives be included?
A: For accurate cost comparison, use net costs after accounting for tax credits, rebates, and other incentives available in your region.
