Calculate your solar savings and plan your energy independence journey
Use Your Average Monthly Units: Don't just use one month's bill. For best results, add up all the units you consumed in the past 12 months, then divide by 12. This gives you a more accurate average.
Why? Electricity usage changes with seasons (more AC in summer, less in winter). Using the average gives you realistic savings calculations.
Off-grid System: Extra solar power beyond what you use doesn't add to your savings (you can't sell it back to the grid).
Bill Savings: Based on current IESCO electricity rates, which typically increase by 12% each year.
Present Value: All future savings are converted to today's money value to give you realistic comparisons.
Solar Panel Performance: Solar panels produce slightly less electricity each year (about 0.5% reduction annually).
Maintenance Costs: Includes system cleaning, repairs, and component replacement over 25 years.
Financial Analysis: Uses standard investment metrics like NPV (Net Present Value) and IRR (Internal Rate of Return) to show if solar is a good investment for you.
