Half Cell module technology

By using half a battery, the current in each busbar is halved. The internal loss in a half cut module is 1/4 that of a full size battery module.

Less Shading Loss

Shading loss of half-cell is much better than normal module in certain shading conditions.

Half-cell technology

The Half-Cell design ensures improved coloring response, resulting in higher yields when partially coloring modules. Under certain shading conditions, semi battery modules experience much better shading losses than traditional modules.

Low Working Temperature

Half cell module reduced by about 2 degrees

Q: What is a photovoltaic (PV) system design?
A: Photovoltaic (PV) system design refers to the process of determining the components and specifications needed for a solar
energy system that meets specific energy needs and requirements.

Q: What are the factors to consider when designing a PV system?
A: The factors to consider when designing a PV system include location, shading, orientation, slope, electricity consumption, budget,
and local regulations.

Q: How do I determine the size of a PV system?
A: The size of a PV system can be determined by considering the energy consumption, the amount of available space for panels, and
the budget for the system.

Q: What is the difference between a grid-tied and an off-grid PV system?
A: A grid-tied PV system is connected to the main electricity grid and sends excess energy generated back to the grid. An off-grid PV
system is a standalone system that is not connected to the main electricity grid and stores energy in batteries for later use.

Q: What is the impact of shading on a PV system?
A: Shading can significantly impact the performance of a PV system by reducing the amount of sunlight reaching the panels. Proper
design and positioning of panels can help minimize the impact of shading.
