Ecoppia, a developer of robotic, water-free PV panel cleaning solutions has introduced its advanced E4 control system. With the integration of real-time and forecasted information on precipitation, cloudiness and air quality, Ecoppia now offers a more intelligent and reliable operation, and provides a comprehensive view of site conditions, helping site managers make better-informed decisions on cleaning schedules.

Problem

The lack of adequate water supply to regularly clean PV modules in arid environments can limit the potential location of utility-scale power plants in high-irradiance locations. Providing module cleaning techniques that minimize water usage or negate the need for water-based cleaning removes key hurdles in site selection.

Solution

Ecoppia designs and produces PV panel cleaning solutions to cost-effectively maximize the performance of utility-scale installations. The company’s water-free, automated technology removes dust from panels on a daily basis to ensure peak output, even in the toughest desert conditions. Supported by a robust control unit, systems can be remotely programmed and managed to minimize O&M costs. Data from The Weather Channel is now fully integrated into Ecoppia’s web-based monitoring and management dashboard, allowing customers to access current weather conditions and forecasts for a given site and schedule cleanings. Because the data is built into E4’s master control, the system can automatically retract any cleaning robots in the field during severe weather events.

Applications

Cleaning PV modules at PV power plants. Used for fixed mount frame systems.

Platform

Ecoppia’s E4 technology is said to cost-effectively remove 99% of dust from fixed mounted PV panels to maintain maximum production levels and accelerate return on investment. Each robotic E4 unit is self-charging, self-cleaning and can be monitored and controlled remotely to mitigate the need for on-site maintenance.
