Solar Sourcing FAQs
Technical answers regarding module certifications, utility grid compliance, BOS hardware, and procurement workflows.
Which solar PV module technologies does BURAQ source for commercial rooftops?
We source high-efficiency Mono PERC and Bifacial modules (540W to 670W+) featuring multi-busbar (MBB) half-cut cell architecture with positive power tolerance. Sourced modules carry IEC 61215 and IEC 61730 international certifications, suitable for industrial sheds and ground-mount arrays.
Are the grid-tied string inverters compliant with WBSEDCL and CESC utility grid standards?
Yes. We source three-phase on-grid string and hybrid inverters featuring dual/multi-MPPT tracking, integrated DC disconnect switches, and grid-compliance documentation required by West Bengal utility bodies (WBSEDCL and CESC) for net metering clearance.
What specifications do your solar DC cables and balance-of-system (BOS) components meet?
Our solar DC cables feature cross-linked polyolefin (XLPO) dual insulation, 1.5kV DC voltage rating, and UV/ozone resistance conforming to EN 50618 (H1Z2Z2-K) / IS 17293 in 4 sq mm and 6 sq mm sizes, paired with IP68 rated MC4 compatible connectors.
How do solar EPC contractors submit project bills of quantities (BOQ) for quotation?
Submit your system specifications (total DC capacity, inverter rating, module mounting structure type, and DC cable drum requirements) to buraq.ep@gmail.com or via our contact form. Our Kolkata desk generates structured offline B2B commercial quotes with factory lead times within 24 to 48 hours.
