UB Solar Solution’s expert technicians rapidly diagnose faults and fine-tune your PV system for maximum efficiency, stable power output, and consistent energy savings. From inverters and strings to wiring, earthing and monitoring—we fix, calibrate, and optimize end-to-end.
Share photos, model numbers and last 7-day data. We shortlist likely causes and arrive prepared.
IV-curve/insulation tests, string tracing, thermal scan, inverter logs, earthing & voltage checks.
We repair faults, re-terminate, update firmware, tune MPPTs, balance strings and set alerts.
Before/after snapshots + KPI sheet (yield, PR, inverter efficiency) so you see the gain clearly.
Karachi City & Surrounding: DHA, Clifton, PECHS, Gulshan, Gulistan-e-Jauhar, Bahadurabad, North Nazimabad, Malir, Korangi, Scheme 33 — plus nearby suburbs by request.
Emergency inverter trips or zero export? We prioritize same-day diagnosis wherever possible.
Engineers + trained technicians with documented QA, torque charts and safety compliance.
You receive a concise diagnostic report with photos, root cause and fixed actions.
We target higher specific yield and reliability to cut your grid draw and bills.
If your bills haven’t dropped as expected, the app shows erratic yield, or the inverter trips at noon, you likely need it. A health check confirms.
Yes—after approval. We stock quality MC4s, fuses, breakers and offer Tier-1 inverter/panel options where replacement is economical.
Every site is unique, but cleaning, string balance and firmware/MPPT tuning often recover noticeable yield and stability.
Absolutely. We service hybrid/off-grid systems, adjust charge strategies and validate SOC windows for longer battery life.
Book a diagnostic visit today and get a clear action plan to recover performance—often within the same day.
