Every string of your solar. Every watt of your energy.
Independent, string-level solar performance monitoring with Solar Performance Cloud — and full electricity visibility across grid, generator and solar with WattEY. AI finds it, solar engineers verify it, and you act on it. Built for commercial and industrial owners across Pakistan.
The problem of underperformance
Solar systems rarely fail loudly. They bleed output slowly — through a dead string, a derating inverter, or a month of Lahore dust — while the plant total still reads “normal”. On the systems we monitor in Pakistan, the losses are not theoretical: they are measured, and they are large. Every unit lost is bought back from the grid at a premium, and under 2026 net billing a self-consumed unit is worth more than ever.
- 61%
- of monitored inverters had a dead string or went silent in 60 days
- 4.8 vs 2.3
- best vs worst daily yield (kWh/kWp/day) — the same sun, less than half the output
- +31%
- output recovered when a single dead string was found and fixed
- 98%
- uptime across the systems we monitor — the other 2% seen the day it happens
Measured on our own platform over 60 days, stated conservatively. No modelled baselines, no invented figures.
The diagnostics challenge
Your inverters already collect a wealth of data — it is just rarely used to understand the true state of your system. Accurate analysis of a live solar plant has traditionally needed scarce, expensive expertise, so most owners stay stuck in reactive mode: acting on underperformance only when it is severe. By then it is usually too late for easy recovery, and high running costs compound the lost revenue.
We turn that data into a clear picture — and give you the tools to become proactive instead of reactive.
What the platform does
Soiling intelligence, real-time fault detection, and honest loss attribution — so you act before the losses compound.
Know when cleaning pays
We track the output your soiling is quietly costing you — so you clean when it makes financial sense, not on a fixed calendar. Your AMC crew does the cleaning; the data decides the timing.
Catch faults before they hurt
Real-time, string-level fault detection: a dead or weak string is spotted in the next polling window and raised as a verified case in minutes — long before the loss shows up on your bill.
Know what you’re losing, and why
We do not just flag underperformance — we quantify each loss and attribute the cause: a dead string, a derating inverter, soiling, or a comms drop. You see exactly where the output went.
How it works
- 1
Onboard your sites
Give us your inverter details and we onboard every site and every brand into one platform, and tune your monitoring. No new hardware or sensors — we work with the equipment you already own.
- 2
AI diagnostics, verified by engineers
Our platform analyses your assets in real time — detecting faults, quantifying losses, and attributing causes down to the individual string. AI flags and prioritises; solar engineers verify each issue before you hear about it.

Act on insight
You receive clear, prioritised recommendations so your team targets the highest-value fixes first — and recovers output. With an AMC, our engineers do the fixing and cleaning too.
The platform
Two complementary platforms — one for your solar, one for your whole electricity picture — backed by the engineers who act on what they find. So you can catch losses before they compound.
Solar Performance Cloud
Every string of your solar
Independent, 24/7, multi-brand inspection down to the individual panel string. It catches the dead string, the derating inverter and the soiling loss your inverter app hides — and turns each into a verified, prioritised action.

Every watt of your energy
Electricity visibility and control across grid, generator and solar in one view — so you know which source served the load, what each unit truly cost, and where automation can shift more of your consumption onto solar.

The hands that keep it performing
Preventive maintenance, professional panel cleaning and fault rectification matched to what the data finds — so the system keeps producing what it was designed to, year after year.

The brain behind the engineering
Every model, alert and inspection method behind these platforms is built and overseen by Engr. Reyyan Niaz Khan — BijliBachao’s energy systems consultant · founder, a UET Lahore electrical engineer with 14+ years in Pakistan’s energy sector and the pioneer of digital energy auditing in pakistan. He is the engineering mind that keeps your solar honest.
