When Is It Applied?

While it is not profitable to use electricity network for supplying electricity for Cathodict protection system because of the cost of elactricity transfer; SDP’s Solar system can provide electricity at fair price .

The Components

The main components which make up a Photovoltaic power generator for application in cathodic protection systems are the solar array, the battery charge controller, the battery storage and the output regulator. The entire system is modular and can be adapted to specific requirements of customers.

Solar Modules

Five high efficiency single-crystal solar modules provide the highest light to energy conversion efficiency.

Cells are textured and have antireflection coating.

Multiple Redundant Contacts provide a high degree of fault tolerance and circuit reliabitility. Circuit is laminated between layers of ethylene vinyl acetate (EVA) for moisture resistance, UV stability and electrical isolation.

Low Iron Tempered Glass Front for strength and superior light transmission.

Rugged Anodized Aluminum frame is designed for exceptional strength.

Side Rails with multiple mounting holes for easy installation.

Tough, multi-layered polymer back-sheet is used for environmental protection, resistance to abrasion, tears and punctures.
