Solar Performance Gap Estimator
Most commercial solar runs below its potential — a few percent lost to soiling, a weak string, or a derating inverter — while the dashboard still shows green. This free estimator gives you an honest range for what that gap could be worth per year, from your system size and electricity rate. It’s a starting figure, not a reading of your system.
Your solar system’s rating, in kilowatt-peak (kWp).
What one unit is worth to you (PKR per kWh). Enter your own.
Estimated recoverable revenue
PKR 160,000 – 480,000 / year
A 50 kWp system, at ≈1,600 kWh/kWp/year, losing 5–15% to avoidable underperformance.
The assumptions behind this
- • Typical Pakistan yield ≈ 1,600 kWh per kWp per year — a planning figure; your site will differ.
- • Avoidable underperformance of 5–15% of output — a composite range from the loss research, not a measurement of your system.
- • Recoverable revenue = generation × that gap × your rate.
This is an estimate, not a promise. It shows what a typical gap could be worth — it isn’t a reading of your actual system. Your real gap depends on your site’s real condition, which is exactly what an independent inspection measures.
From an estimate to a real number
This tool tells you whether the gap is worth chasing. Measuring your actual gap tells you exactly where it is and what to fix.
It starts with typical numbers
The estimate uses a typical Pakistan yield and a published range for avoidable underperformance — clearly shown, so nothing is hidden.
Your real gap is measured, not assumed
A typical range isn’t your system. Independent, string-level inspection compares each string to a weather-normalised expectation and finds your actual gap.
Most of it is recoverable
Soiling, a weak string, a derating inverter — most causes are fixable, which is why the gap is recoverable revenue rather than a permanent loss.
Questions about the estimate
- What is the solar performance gap?
- The difference between what your solar system should produce, against a weather-adjusted expectation, and what it actually produces. Most of it comes from fixable causes, so most of it is recoverable.
- How accurate is this estimator?
- It’s a planning estimate, not a measurement. It uses a typical Pakistan yield and a composite underperformance range to show what a gap could be worth — deliberately as a range. Your real number depends on your system’s actual condition.
- Where do the numbers come from?
- The typical yield (≈1,600 kWh/kWp/year) is a standard Pakistan planning figure; the 5–15% underperformance band is a composite from published loss research. The tool multiplies generation × that gap × the rate you enter.
- How do I find my system’s real gap?
- By measuring it — independent, string-level inspection compares each string to a weather-normalised expectation and attributes the shortfall to a cause. That turns this estimate into an actual, itemised figure.
