Description
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.
