Eco life provides thin film panels (a-si & c-si) with close partnerships with our partner. By automatic production lines from switzerland and imported raw materials, we ensure more reliable performance.

Compared to crystalline solar panels, thin film panels has higher temperature co-efficient of pmax(-0.29%), which ensures higher(20%) power output, especially in hot areas.

In addition, thin film panels can be used as environmental construction materials in bipv projects.

Solar pumps system

Solar pumping system becomes more and more popular, it can be applied to daily use (underground water), agriculture irrigation, forestry irrigation, desert control, pasture animal husbandry, water supply for islands, wastewater treatment engineering, and so on. In recent years, with the promotion of the utilization of newenergy resources, solar pumping systems are more and more used in municipal engineering, city centresquares, parks, tourist sites, resorts and hotels, the landscapes and fountain systems in the residentialareas.This system is composed of a solar array, a pump and a solar pumping inverter.

In recent years, with the promotion of the utilization of newenergy resources, solar pumping systems are more and more used in municipal engineering, city centresquares, parks, tourist sites, resorts and hotels, the landscapes and fountain systems in the residentialareas.This system is composed of a solar array, a pump and a solar pumping inverter. Based on the designphilosophy that it is better to store water than electricity, there is no energy storing device such as storebattery in the system.

Inverter Features:
Adopting the proposed dynamic VI maximum power point tracking (MPPT) control method; Fast
response speed and stable operation; Better than the conventional methods which may lead to the
problems including poor tracking performance, unstable operation or even damaging water hammer
effects when the irradiation on the array change rapidly.
Digital control with full automatic running, data storage and complete protective functions (overload, over
voltage, under voltage, over heat, reverse polarity, thunder, over flow and dry running).

The main circuit adopts intelligent power module (IPM), with high reliability and high efficiency 98%.
Unique design of aluminum alloy with good cooling and shielding, LCD display (43*29mm) and keys,
easy operation, good view through LCD when setting parameter, feel comfortable.

Protection degree IP41, working temperature: -10c+50c
Inverter connects to city power when there is no sunshine to keep system pumping water is available
(optional).

Low voltage drive device is our patent right product, can be used in small solar pumping system to save
the quantity of solar panels.
