Q&A

The return on investment is typically 25 – 100% based purely on energy savings. This will depend on the optimisation setting of the powerPerfector, the mixture of equipment running on the site, the 'load factor' and energy unit cost.

Load factor = Average demand (as a %)
                       Maximum demand

The load factor will be higher if a site operates over long hours and has a continuous base load demanding power. A higher load factor will allow the capital costs of the unit to be recouped at a faster rate, increasing the ROI. Maintenance cost savings of appliances will also be achieved, which can further reduce the ROI period. There are no associated maintenance costs with the unit itself as it has no moving parts.
