The service covers the entire project lifecycle, from initial site assessment and technical design to equipment supply, construction, grid connection, intelligent operation and maintenance (O&M), and asset management.
Thanks to the integration of advanced technology and proven engineering processes, our solutions deliver high power generation efficiency, maximum safety, low operating costs and stable performance for decades.
Double-glass bifacial module with TOPCon or PERC (N-type) technology.
Its power range is from 550 W to 720 W, with conversion efficiency of 23% to 25.5%.
The product comes with a 12-year factory warranty, supplemented by a 25-year linear performance warranty to ensure long-term power generation stability.
For industrial and commercial applications, string inverters with a power range of 50 kW to 110 kW are adopted, designed to guarantee flexibility and high performance in distributed systems.
For large-scale ground-mounted solar power plants, central inverters of 500 kW or above are used, optimized for large-capacity projects and continuous operation.
Both types of inverters achieve a conversion efficiency of ≥98.5% and allow an oversizing ratio of 1.2 to 1.4 times, which helps maximize the energy production of the photovoltaic system.

For large-scale ground-mounted solar power plants, central inverters of 500 kW or above are adopted, optimized for high-capacity projects and continuous operation.
Both configurations achieve a conversion efficiency of 98.5% or higher and allow an oversizing ratio of 1.2 to 1.4 times, which helps optimize the energy production of the photovoltaic system.
The system is complemented by a full range of electrical and control components, which ensure safe integration and stable operation of the entire photovoltaic installation.
It includes photovoltaic cables and alternating current (AC) cables, combiner boxes, electrical distribution cabinets, overvoltage protection devices, smart energy meters, and communication modules for system monitoring and management.
DonE’s photovoltaic plant adopts a highly integrated modular architecture to maximize efficiency, reliability and grid compatibility.
The system starts with an array of high-efficiency photovoltaic modules that convert solar radiation into direct current energy. This power is collected and managed by the convergence system via combiner boxes and high-voltage cabinets.
Subsequently, string or central inverters perform DC-to-AC conversion with advanced MPPT technology to optimize energy output.
The generated power flows to the distribution system, consisting of AC cabinets and step-up transformers, which condition the power for grid-level transmission.
Finally, the grid connection system ensures safe and compliant operation via anti-islanding protection, reverse power flow control and continuous power quality monitoring.
The integration of these modules enables the construction of scalable, high-performance solar plants designed for stable operation throughout their service life.
The combination of N-type bifacial modules (TOPCon / PERC) with high-efficiency inverters and multi-channel MPPT increases energy output by 5% to 15%.
Comprehensive IP65/IP67 protection, with lightning, overcurrent, overvoltage and anti-islanding protection. Compliant with IEC regulations and local grid connection standards.
Real-time remote monitoring, automatic fault diagnosis, data analysis and intelligent reports that greatly reduce maintenance costs.
Optimization via 3D simulation, shadow analysis and designs adapted for rooftops, ground, water surfaces and complex terrain.
Full support for grid connection at 10 kV, 35 kV and 110 kV networks, including documentation, application processing and inspection.
Optimized BOS design, standardized construction and service life over 25 years to maximize return on investment.
Solar solutions for the industrial and commercial sector are installed on factories, warehouses, shopping malls, office buildings, schools, hospitals and industrial parks, with capacities ranging from 100 kW to 50 MW. These systems greatly cut electricity costs, accelerate operational decarbonization and increase the value of real estate assets, while delivering attractive medium-term returns.
For domestic applications, photovoltaic systems are suitable for villas, rural houses and private rooftops, with typical power ranging from 3 kW to 30 kW. Its main benefits include direct savings on electricity bills, a certain level of energy independence and tangible contributions to environmental sustainability, all with simple maintenance and long service life.
Large photovoltaic power stations are usually located in deserts, wasteland, arid hills or vast open land. The capacity starts from 10 MW and can exceed several GW. Typical configurations include solar trackers, central inverters and step-up substations, which fully leverage economies of scale, achieve extremely high energy output, and guarantee stable, predictable revenues for decades.
