If your consumption is low, bigger solar size will cap at your monthly units.
اگر یونٹس کم ہوں تو بچت آپ کے یونٹس تک محدود رہے گی۔

How Solar Savings Calculator Helps You Estimate Electricity Bill Reduction
Installing solar panels can significantly reduce your monthly electricity bill, but the actual savings depend on your current consumption, electricity tariff, and solar system size. This solar savings calculator helps you quickly estimate how much you can save if you switch to a solar energy system based on your real household usage.
By entering your monthly electricity bill and average units consumed, the calculator determines your effective per-unit electricity cost. It then compares this with the expected solar energy generation from different system sizes (1kW to 3kW). Based on this comparison, it shows your estimated monthly bill reduction, solar generation potential, and long-term savings over multiple years.
This approach gives a realistic projection because solar savings cannot exceed your actual electricity usage. For example, if your home consumes fewer units than a solar system produces, the savings will be capped at your consumption level. This makes the estimate practical for households with lower monthly units, especially under 200 units.
The calculator also provides long-term projections, helping you understand how solar adoption can reduce energy costs over 1, 5, 10, and 20 years. These insights are useful for planning energy upgrades, evaluating solar suitability for your home, and understanding the financial impact of switching to solar power.
For best accuracy, use the average electricity bill and units from your recent months. This ensures the savings estimate reflects your actual consumption pattern rather than seasonal variations.
Solar Savings Calculator FAQs
Quick answers about bill, units, solar size, and savings estimates
This calculator estimates your monthly electricity bill savings by comparing your current consumption with expected solar generation.
- Estimated monthly savings (PKR)
- Solar generation (kWh/month)
- Bill reduction percentage
- Long-term savings for 1, 5, 10, and 20 years
It uses your bill and units to find your approximate per-unit cost, then applies estimated solar generation for your selected system size.
Because the calculator needs to estimate your average per-unit electricity cost.
Per-unit cost = Monthly Bill ÷ Monthly Units
Once per-unit cost is known, the calculator estimates how many units solar can offset, then converts that into PKR savings.
The calculator uses an average production assumption:
- 1 kW ≈ 130 kWh/month
- 2 kW ≈ 260 kWh/month
- 3 kW ≈ 390 kWh/month
Actual output can vary with sunlight hours, panel quality, tilt, shading, and maintenance.
Because you cannot save more units than you actually consume. The calculator uses:
Units Saved = min(Solar Generation, Monthly Units)
If your monthly units are lower than the solar estimate, the savings stop at your consumption level. This keeps the results realistic.
This calculator is designed for scenarios where monthly consumption is under 200 units (kWh).
If your units are above 200, the calculator shows an alert because it is meant to evaluate low-consumption households based on the set rule in your code.
If you want it to work for all consumption levels, you can remove the 200-units validation in JavaScript.
Long-term savings are calculated by multiplying the estimated monthly savings:
- 1 Year: Monthly Savings × 12
- 5 Years: 1 Year Savings × 5
- 10 Years: 1 Year Savings × 10
- 20 Years: 1 Year Savings × 20
This is a simple projection. It does not include tariff changes, inflation, or performance degradation over time.
You can improve accuracy by using realistic inputs:
- Use average bill and units from the last 3 to 6 months
- Check units (kWh) directly from your electricity bill
- Avoid peak-season spikes and use an average
- Consider any major change in usage (AC, heaters, new appliances)
Bill reduction depends on how much of your monthly units are offset by solar.
Bill Reduction % = (Units Saved ÷ Monthly Units) × 100
If your units are low and solar generation is close to your usage, reduction percentage can be very high. If usage is higher than solar generation, it will be lower.
