IET 550-Watt Monocrystalline Solar Panel IE-7M144-HC
The IET IE-7M144-HC is a 550-watt monocrystalline solar panel built for homes, businesses, farms, schools, clinics, institutions, NGOs, and commercial solar installations that need dependable power generation from a high-output module.
This panel uses monocrystalline PERC cell technology, a half-cell design, and multi-busbar technology to improve module performance, current collection, and reliability. It is designed to perform well under high-temperature and low-light conditions, making it suitable for practical solar installations in demanding environments.
With 550W rated output, 21.28% module efficiency, Voc of 50.0V, Vmp of 41.8V, Imp of 13.16A, Isc of 13.94A, 1000VDC / 1500VDC maximum system voltage, 25A maximum series fuse rating, and a 30-year linear power output warranty, this IET solar panel is a strong choice for customers who need reliable solar power with long-term warranty support.
3 Things to Consider When Buying a Solar Panel
- System design and compatibility: This 550W panel has a Voc of 50.0V and Isc of 13.94A at STC, so the installer must confirm string sizing against the inverter or MPPT charge controller voltage and current limits.
- Installation environment: The module is designed for good performance under high-temperature and low-light conditions, but final energy output still depends on roof direction, tilt angle, shading, ventilation, mounting quality, and site conditions.
- Handling and mounting: This is a large panel measuring 2279 x 1134 x 30mm and weighing 28kg, so proper transport, lifting, mounting rails, clamps, and installer handling are important.
Best For
This IET 550W solar panel is best for homes, businesses, farms, schools, clinics, NGOs, institutions, commercial buildings, and solar projects that need high-output monocrystalline panels with strong efficiency, durable construction, and long-term warranty support.
