Haitai

Haitai is a solar panel manufacturer with CEC-approved photovoltaic modules available in the Australian market. Its product range centres on the HT series of panels, built around mainstream silicon cell technology rather than any battery or energy-storage line.

The company's modules use PERC and TOPCon cell technology with a half-cut cell design. Half-cut cells split each cell in two to lower resistive losses and improve performance under partial shading, while TOPCon (tunnel oxide passivated contact) is a higher-efficiency cell architecture that has become common across residential panels for its improved low-light yield and temperature behaviour. These are module-level technologies; the entry lists no battery chemistry and no integrated storage system.

For Perth homeowners, panel efficiency matters because of the region's strong solar resource of roughly 5.0 peak sun hours per day, which lets a well-specified array generate significant daytime output and offset usage billed at the Synergy A1 tariff. As with any panel brand, confirm the product warranty, performance-degradation terms, and local service support, and check your SAA-accredited installer's experience with the brand before purchase.
