Rooftop photovoltaic (PV) mounting system are the core structural system installed on building roofs to fix and support PV modules.
Based on roof type, they are usually divided into flat roof mounting system (often using concrete counterweight foundations to avoid damaging the waterproofing layer) and pitched roof mounting system (fixed to the structure under roof tiles or on corrugated steel sheets by hooks or clamps). Based on materials, they commonly use carbon steel or aluminum alloy.
Floating photovoltaic (PV) mounting systems help to install modules on the water surface (such as lakes, reservoirs, and ponds) to generate electricity. They mainly consist of high-density polyethylene (HDPE) floats, brackets for solar modules, brackets for inverters, and anchoring system. They are suitable for waters with considerable depth where piling is not feasible.
The floating PV saves land resources. The cooling effect of the water can improve power generation efficiency by approximately 10% ~ 20%. The surface coverage can reduce evaporation by up to 70% and inhibit algae growth. The HDPE material is safe to contact drinking water.
The ground mounting structures are supporting systems installed on the ground foundation and used to fix and bear the photovoltaic (PV) modules. They are essential component of solar farms to ensure the power generation efficiency and safety.
The foundation types include ground screw pile, spun pile, ramming pile, concrete block and cast-in-place foundation.
Solar tracking systems effectively improve irradiance reception efficiency and power generation by driving photovoltaic modules to follow the sun's position in real time. They are mainly divided into three types: horizontal single-axis (high cost-effectiveness, simple structure), tilted single-axis, and dual-axis (all-angle tracking, higher gain).
Compared to fixed mounting, they can typically increase power generation by 10% to 40%. The system integrates key technologies such as intelligent tracking algorithms, independent or multiple controls, slewing drive, and automatic protection under different weather and maintenance conditions.
The Building Integrated Photovoltaics (BIPV) use photovoltaic modules directly as building materials, as such roof, curtain wall, waterproof shed, sunroom.
BIPV solution achieves a deep integration of power generation, building materials and aesthetics, thereby transforming the building from an energy consumer into a producer.

On July 8-9, Solar & Storage Live Vietnam 2026 was held at SKY EXPO in Ho Chi Minh City. The event brought together over 5,500 attendees, more than 200 exhibitors, and over 120 speakers. Solar First Group showcased its three major product lines—rooftop mounting systems, ground mounting systems, and floating systems—at Booth 1-M14. Thanks to the robust performance of its products and a precise understanding of the Vietnamese market's needs, the company attracted numerous local Vietnamese and Southeast Asian clients to stop by and engage in discussions. Roof Mounting Systems: Precisely Meeting Vietnam's Surging Demand for Distributed PV Vietnam is promoting the development of rooftop solar power with unprecedented vigor. In March 2026, the Prime Minister of Vietnam signed Directive No. 10/CT-TTg, whose core provisions focus on strengthening energy conservation efforts and promoting the development of rooftop solar power. The Ministry of Industry and Trade subsequently issued an implementation plan, setting a national electricity savings target of no less than 3% for 2026, with the savings target during the high-temperature peak consumption season (April–July) raised to no less than 10%. Clear annual development goals were established: 10% of government agencies and 10% of residential homes nationwide are to complete the installation of rooftop solar systems. In terms of policy incentives, Vietnam's government recently issued Decree No. 243/2026, raising the cap on the proportion of surplus rooftop solar power fed into the grid from 20% to 50%. Provided grid capacity allows, this proportion may be further increased before December 31, 2030. In areas not connected to the national grid—such as mountainous regions, border areas, and islands—there is no cap on the sale of surplus electricity. The rooftop mounting systems exhibited by Solar First Group are made of high-strength aluminum alloy with an anodized surface treatment, ensuring a long service life. Installation requires no drilling or welding, preserves the roof's waterproofing, and is compatible with a variety of roof types. Against the backdrop of accelerated rooftop solar installations by Vietnamese government agencies, businesses, and residential homes, these products provide reliable support for all types of rooftop solar projects. With an aluminum alloy recycling rate as high as 95%, they meet the requirements of a circular economy. Ground Mounting Systems: Supporting Large-Scale Ground-Mounted Power Plants and Off-Grid Projects in Vietnam The solar market in Vietnam is growing rapidly. According to the 8th Power Development Plan (PDP VIII), Vietnam has set a target of 46 GW to 73 GW of solar installed capacity by 2030. Market data indicates that the Vietnamese solar market was valued at approximately 19.5 GW in 2025, is projected to grow to 21.76 GW by 2026, and is expected to reach 37.63 GW by 2031. The ground mounting systems exhibited by Solar First Group are suitable for large-scale ground-mounted power plants, offering easy installation and adaptability to complex terrain. The main material used is a new type of aluminum-magnesium-zinc-coated steel, which provides excellent corrosion resistance and comes with salt spray test reports. In regions such as the Central Highlands of Vietnam—where solar resources are abundant but terrain is diverse—these products can effectively handle challenging terrain conditions such as steep slopes and ravines, providing a cost-effective support solution for ground-mounted power plant construction. Floating PV Systems: Aligning with the Trend of Large-Scale Floating PV Development in Vietnam's Water Areas The floating PV (FPV) market in Vietnam is expanding at an accelerated pace. Recently, Son La Province launched a large-scale FPV project with an installed capacity of 800 MW. With a total investment of approximately 17 trillion VND (approx. 646 million USD), the project spans over 1,139 hectares of water surface and will be constructed in four phases. The first phase of 200 MW is expected to be commissioned in 2027. In Dak Lak Province, the 304 MW KN Srepok 3 FPV project, with an investment exceeding 7.66 trillion VND, is scheduled to go online in the fourth quarter of 2027. Multiple other FPV projects are also underway in provinces like Gia Lai. Furthermore, Power Generation Joint Stock Corporation 1 (EVNGENCO1) has proposed the investment and construction of 3 floating PV projects in the reservoir areas of Lam Dong Province, with a total capacity of nearly 270 MW.
