Cathodic Protection

Solar electric systems are a reliable cost effective power source for impressed current cathodic protection systems when conventional energy sources are unavailable or difficult to access.

The use of solar systems allows the cathodic protection engineer the flexibility to locate exactly the right amount of power at the precise location it is required.

Matching the output of a PV system (typically from 12V or 24V batteries) to the CP load is achieved through energy efficient, high frequency pulse width modulation (PWM) impedance converters. The CP controllers are fully automatic and will adjust the output against feedback from one or more of the following parameters:

	output voltage;
	output current;
	reference cell.

Solapak Systems has been a leader in the supply of complete solar electric systems for the cathodic protection of oil pipelines in the Middle East and North Africa since the early 1980s. Our system design aims to provide years of reliable, low maintenance and environmentally friendly operation.

A standard Solapak solar system comprises:

	Solar modules to generate electricity;
	Array structure to support the solar modules;
	Batteries to store the energy to ensure continuous power to the load;
	Charge controllers to optimise the use of available energy, minimise maintenance and maximise component lifetime;
	Output cathodic protection controller to supply power to the protected structure;
	Cables, hardware etc. to the point of use (the output of the CP controller).

In addition Solapak Systems offer:

	Wide range of system capacities and voltage;
	Options for monitoring and metering system performance;
	Choice of array mounting to ensure easy installation even for the most difficult sites;
	Selection of battery types and size to suit local conditions;
	Standard GRP or thermally insulated battery boxes and equipment shelters;
	A source of components for spare parts or to upgrade existing sites;
	Potential to hybridise with other energy sources to prolong life and reduce operational costs;
	Consultancy services to provide the client with independent engineering design, contract management, inspection, training and on-site commissioning.
