Longi Solar LR5-66HIH-500M Solar Panel, 500 W

Description

To build an efficient solar power plant, you need to select high-quality panels that will maintain their performance over the long term. At the same time, the panels must be high-powered and highly reliable.

This solar photovoltaic module meets the criteria for high quality, reliability, and operational efficiency LR5-66HIH-500M, developed by the company LONGI Solar. This company is considered one of the best in the solar energy market. It consistently ranks highly in the Tier-1 rankings (the most well-known solar panel manufacturers). The companies on this list have their own automated production lines and utilize their own innovations in the field of green energy. Therefore, there is no doubt about the quality of LONGI Solar’s products.

Technical Specifications of the LR5-66HIH-500M Photovoltaic Module are as follows. The maximum power of the photovoltaic module is 500 watts. The open-circuit voltage (Voc) is 45.55 V, the voltage at maximum power (Vmp) is 38.38 B. The short-circuit current (Isc) is 13.90 A. The current at maximum power (Imp) is 13.03 A.

The efficiency of a solar photovoltaic module is quite high and amounts to 21.1%. The high efficiency is due to the use of modern monocrystalline solar cells (Half-Cell technology). Monocrystalline panels are more efficient, of higher quality, and more durable than polycrystalline ones.

The device’s housing is made of anodized aluminum, making it corrosion-resistant and ensuring the panel is lightweight and durable. The photovoltaic module is covered with high-quality tempered glass 3.2 mm thick, which can withstand concentrated mechanical loads (5,400 Pa from the front—snow—and 2,400 Pa from the back—wind).

The degradation (wear and tear) of this type of solar panel over a 25-year service life is only 15.2% (84.8% of the initial power output is guaranteed to be retained).

The dimensions of the photomodule are as follows: 2093 × 1134 × 35 mm. The weight is 25.3 kg. The number of solar cells in the photovoltaic module is 132 (6×22). The temperature coefficient of power is -0.340 %/°C. The distribution box's IP68 protection rating allows it to withstand harsh weather conditions, and exposure to dust or moisture does not affect the panel's operation in any way.

The projected service life is over 25 years. The official warranty on materials is 12 years, and the warranty on linear power retention is 25 years.
