Why is Twisun Pro Better Suited for Residential Rooftop PV Systems?
In rooftop photovoltaic (PV) systems, solar panels are typically installed close to the roof, which can lead to poor heat dissipation. This not only affects power generation efficiency but also increases the risk of fire hazards. Twisun Pro, however, addresses these challenges with its advanced N-TOPCon technology and 1/3 cell cutting technology. These innovations successfully lower the operating temperature by 40%, while boosting power output by 7.22%. As a result, Twisun Pro significantly enhances power generation efficiency and improves performance in high-temperature environments.
Moreover, the 1/3 cell cutting technology effectively reduces current and series resistance losses, further lowering the operating temperature and minimizing the risk of hot-spot formation. This, in turn, improves overall electrical safety. The low-current design ensures that the panels operate more stably and reliably, eliminating the potential fire risks associated with rooftop PV installations. By safeguarding your property, Twisun Pro stands out as the ideal choice for residential rooftop PV systems.
Twisun Pro Offers Greater Flexibility in Installation
Lighter Roof Load:
The Twisun Pro features a lightweight dual-glass structure, weighing only 21 kilograms. This makes transportation and installation easier while significantly reducing the load on the roof. The lightweight design ensures that the panels can be installed effortlessly on a variety of rooftop conditions without adding extra stress to the structure.
Improved Compatibility:
Twisun Pro is designed for easy integration, with low current and a standard size of 1.998 square meters, making it compatible with common inverters and mounting systems. This ensures both the convenience and efficiency of system integration. The standard size design allows for seamless compatibility with a wide range of commonly used mounting systems, facilitating quick and efficient deployment.
