Project Outline

Key Drivers:  Meeting Corporate Sustainability Goals and Cost Efficiencies.

Key Reasons for Purchasing:  Quality Products with a Quality Supplier to Supply, Install and Service.  Also, Client Service and Design were superior and very knowledgeable.

Challenges: Finding the most suitable buildings to install solar panels, locating the inverter, and having access to an electricity supply.

Consumption and Generation data were required for Education Purposes at the College.

Solutions

Two newer roofs were selected with one north facing and one west facing.  West facing gave afternoon generation to assist with afternoon peak demand consumption at the college.

Inverters were located on external walls of each building, under the verandah roofs and the electricity supply was connected at the sub distribution board in each building – part of the reason they were chosen.

An SMA Energy Meter and Home Manager were added to the SMA Inverter. This enables any computer at the college to login and access the data about the system’s performance at any time.  This was a one time cost with no annual subscription fees or data costs.
