05   INDUSTRIAL KNOWLEDGE BASE

Frequently asked questions: 500 kW industrial solar.

Technical and regulatory answers for factory managing directors, procurement heads, and chief electrical engineers.

COST What is the total turnkey cost of a 500kW industrial solar plant in Pakistan?

A complete 500kW industrial solar system in Pakistan costs between PKR 37 Million to PKR 46 Million. This covers 855+ Tier-1 TopCon modules, 100kW/250kW inverters, a dedicated 630 kVA (0.8kV/11kV) step-up transformer, 11kV VCB switchgear panel, civil work, and full NEPRA net-metering commissioning, yielding complete capital payback in 2.0 to 2.2 years.

11kV TX Why do we need a 630 kVA step-up transformer for a 500kW solar plant?

In Pakistan, utility DISCOs mandate that solar generation exceeding 100kW must synchronize with the electrical grid at 11kV high-tension (HT) level to prevent low-voltage transformer overloading. TransfoLine manufactures custom inverter-duty step-up transformers (0.8kV to 11kV) equipped with electrostatic shielding and K-factor harmonic mitigation specifically for this purpose.

SAVINGS How much annual electricity savings does a 500kW industrial solar plant generate?

A 500kW plant produces 700,000 to 740,000 units annually. Based on Pakistan's industrial B-2/B-3 tariffs averaging PKR 52โ€“58/unit, this delivers over PKR 36 Million to PKR 43 Million in annual utility bill reductions.

SPACE How much roof space is required for a 500kW industrial solar installation?

Using 585Wโ€“600W Tier-1 bifacial panels, a 500kW installation requires approximately 38,000 to 42,000 square feet of unobstructed factory shed roof or ground space. Our structures clamp securely onto industrial shed purlins without drilling or causing roof water leakage.

GENSET Can the 500kW solar system run alongside our industrial diesel generator?

Yes. We install advanced DG-PV reverse-power protection controllers that enable the 500kW solar plant to generate power simultaneously with your diesel generator during grid outages, reducing factory diesel consumption by up to 70% without genset reverse-power tripping.

NOC What is the timeline for 11kV NEPRA net-metering approvals?

TransfoLine manages the complete 11kV DISCO liaison (LESCO, K-Electric, FESCO, MEPCO, IESCO). The process typically takes 6 to 8 weeks, including PEC design approval, M&T green meter testing, and live grid energization.
