Disclaimer: This calculator provides estimates based on the information you provide and makes assumptions about electricity price increases, solar system performance, and maintenance costs. Actual results may vary based on many factors including your specific usage patterns, location, system quality, and future electricity prices. We recommend consulting with a professional solar installer for a detailed assessment.
Notes:
- The calculation accounts for the time value of money by considering the upfront costs of solar versus the monthly payments for Eskom.
- Solar system performance typically degrades by about 0.5% per year, which is factored into the calculations.
- The calculator assumes you remain connected to the grid, with the solar coverage percentage determining how much you still rely on Eskom.
- Additional savings from potential feed-in tariffs (if you can sell excess electricity back to the grid) are not included in this calculation.
- The calculator does not account for potential tax incentives or rebates that may be available.
