BigK+ Commercial Rooftop Solar

SolarBK is a Vietnamese solar energy company headquartered in Ho Chi Minh City, with more than 15 years on the market and research roots dating back to 1975. It provides EPC, operation and maintenance, monitoring and financing for clean energy systems, and is linked to the IREX solar panel factory.

BigK+ is its solar power package for business customers needing 50 kWp to 1.2 MWp. It is sold as a Standard package (system design) or an Advance package (full turnkey), uses Grade A IREX panels made in Vietnam, and comes with a 10-year warranty on the system and its output plus a 90% output insurance package from BIC. Systems are monitored through SolarBK's proprietary SSOC software. A SOLAR ESCO option lets firms use the system first and own it later without upfront capital.

• Sized for business: systems from 50 kWp to 1.2 MWp for factories and commercial buildings.
• Two packages: Standard for system design only, or Advance for full turnkey delivery.
• Locally made panels: Grade A IREX panels produced in Vietnam to European and US standards.
• Output insurance: 90% electricity output insurance from BIC on top of a 10-year warranty.
• SSOC monitoring: proprietary software for 24/7 online tracking of output and fault alerts.
• ESCO financing: a use-first, own-later model with no upfront capital.

A brick, textile or plastics factory can install a BigK+ system on its roofs to cut daytime grid consumption. Logistics depots and shopping centres can use the ESCO option to switch to solar without capital spending. Multi-site retailers can track output across locations through SSOC.

The company states that BigK+ can cut monthly electricity bills by 30-70% and commits to payback within the output insurance period. The system and its output carry a 10-year warranty, with a 90% output insurance package from BIC. Under the ESCO option, monthly electricity can cost up to 30% less than EVN rates with no upfront investment.

Rising electricity tariffs and new rules for self-consumption rooftop solar in Vietnam are pushing factories to generate their own power. Export manufacturers also need renewable electricity to meet buyers' carbon and ESG requirements, which favours rooftop systems with financing and monitoring included.

Headquartered at 47 Le Van Thinh, Ho Chi Minh City. Reference projects include the Truong Sa micro-grid (8,500 kWp), an EVN project chain (3,800 kWp) and a Vincom chain (13,413 kWp). The company cites two Energy Globe Awards and a construction partnership with Coteccons.
