1. A Fully Integrated, Made-in-Vietnam Solar Ecosystem
Designed for households and small businesses with capacities ranging from 2 to 20 kWp, BigK differentiates itself through its full-system integration.
At its core are IREX solar modules—mono 390 Wp panels meeting UL, TÜV, and BIS standards, insured by Munich RE. These modules are paired with SolarBK-designed inverters boasting efficiencies over 97%, optimized for the tropical climate.
The SSOC monitoring platform provides real-time system tracking with Vietnamese interface and Norton Security data protection. Together, this “Make in Vietnam” ecosystem ensures stability, safety, and transparency throughout the system’s 25-year lifespan.
2. BIC Energy-Yield Insurance – A Rare Guarantee in the Market
BigK is among the first Vietnamese solar solutions to include 5-year energy-yield insurance from BIC. If actual production falls below the guaranteed output, customers receive compensation. With a typical payback period of 5 years and a lifespan of 25 years, BigK stands as a low-risk, high-impact long-term investment.

In Hanoi, many households have confidently chosen the BigK solar power solution through the “Million Green Houses” program implemented by SolarBK. The program helps customers significantly reduce their household electricity costs, while enabling them to be more proactive in using clean energy—an essential trend given continuously rising electricity prices and increasing demands for energy saving.
In the commercial sector, BigK and BigK+ continue to assert their effectiveness in large-scale projects. A prominent example is the rooftop solar power system, exceeding 13,413 kWp, that SolarBK deployed for the Vincom Retail commercial center chain. By applying the BigK+ solution, the system ensures stable operation, enhances power usage efficiency, and contributes to the sustainable development strategy of Vietnam’s leading retail network.
In the industrial sector, BigK and BigK+ have been selected by many manufacturing and logistics enterprises to optimize energy costs, reduce reliance on the grid, and better meet environmental and ESG standards. Large entities such as Vincom, ICD Tan Cang, and TongHong have chosen to partner with BigK+ as part of their long-term operational strategy. For them, this is not just an energy system, but a way to affirm their vision, green manufacturing, sustainable growth, and adaptability to global trends.
In the tourism and resort sector, SolarBK's rooftop solar power solution has also been deployed for numerous large-scale projects nationwide. These projects demand high standards in aesthetics, durability, and operational capability under specific weather conditions (intense heat, sea wind). BigK+ proves its suitability thanks to its synchronous design and international quality standards.

BigK is also strongly present in community programs in remote and underserved areas, where the need for stable electricity is particularly crucial. Through the “Contributing Every Ray of Sunshine – Lighting Up the Future” program, SolarBK, along with its partners, has supported the installation of solar power systems integrated with battery storage at many mountainous schools in Northern Vietnam. This provides a sustainable power source, helping schools be proactive in teaching and reducing operating costs. These are practical models that contribute to improving learning conditions for students in highland regions.
These projects, spanning households, commercial, industrial, and community sectors, show that BigK is not merely an energy solution but a tool that drives the clean energy transition on a broad scale. Furthermore, they affirm SolarBK’s deployment capacity in bringing “Make in Vietnam” technology to diverse market segments, helping steer Vietnam towards sustainable development goals.
