Solar Electricity

Electricity is directly produced from the sun & converted for on-demand use in your factory/stored for use at another time. The systems available can be independent (stand-alone) of the main electricity supply grid/work in conjunction with your existing electricity supply. The system is made up of solar panels & an inverter (converts DC power from the solar panels to AC power for consumption). In some cases batteries are also included to store the excess power.

There are currently two types of incentives available to the factory owner:

  • The Department of Trade and Industry provides a grant for Green Technology and resource efficiency improvement . The fund is performance driven and the amounts granted are based on certified Financial statement detailing manufacturing turnover in relation to energy saving initiatives. The objective of this incentive is to support projects with green technology upgrades and business development activities that will lead to cleaner production and resource efficiency. Read more
  • Eskom also offers a rebate based on performance (how much electricity is save). The rebate is offered under the demand management funding models.

What You Need To Know:

Avoid a complex duct system with limited access. Ideally the entire system should be exposed but networked outside main work areas

The HVAC system must deploy the correct drive to suit a specific job requirement. In order for this to happening on an on-going basis, operation settings must be flexible and programmable according to specific machining requirements

Match capacity to the required performance. Deploy lower-cost variable-speed drives in smaller sized systems

There are a number of advanced management and monitoring systems which can be retrofit to existing HVAC systems

The system must have the ability to deploy only in areas where required and switched off in areas of the factory network where extraction not required

The factory HVAC system is usually designed within the overall fire prevention plan. It is vitally important that the system is designed to provide a smoke free escape by accurately maintaining the air pressure along the designated escape routes

A multidirectional system with forward & reverse speed ensures flexibility & allows adjustments for future production line planning & fire control requirements

High-efficiency motors are an option that would reduce fan and pump power in all applications
