Industrial Solar EPC FAQ.
Answers to common questions regarding industrial rooftop solar, equipment guarantees, and net-metering approvals in Pakistan.
HARDWARE Which solar panel brands does TransfoLine supply?
TransfoLine exclusively supplies Bloomberg NEF Tier-1 certified N-Type TopCon and Bifacial solar modules from global leaders including Jinko Solar (Tiger Neo), Longi Solar (Hi-MO X6/X7), and Canadian Solar, backed by 12-year product and 25-year linear performance warranties.
TRANSFORMER Why does TransfoLine manufacture its own step-up transformers?
Standard distribution transformers overheat and fail on solar loads due to inverter PWM harmonics and DC bias. TransfoLine builds specialized K-9 rated copper transformers with electrostatic Faraday shielding, ensuring seamless 30-year operational life with zero harmonic breakdown.
NET-METERING How long does the NEPRA net-metering process take?
From initial 11kV feeder load flow study submission to final DISCO bi-directional green meter installation and commercial COD, TransfoLine completes the entire turnkey regulatory process in 45 to 60 days.
MAINTENANCE What after-sales maintenance support is provided?
Every TransfoLine industrial solar project includes a complimentary 12-month Operation & Maintenance (O&M) contract with monthly drone thermal imaging inspections, inverter diagnostic logs, transformer oil BDV testing, and 24/7 on-site emergency support.
