80kW Apartment system

We love the Shire, so an opportunity to work in our neck of the woods on an apartment block who decided to go solar was perfect.

This project required us to work with a variety of stakeholders and pay close attention to approvals and engineering due to it’s location. We were also required to fit special grid network protection equipment, something we are seeing more frequently these day.

We paid special attention to fitting the solar array’s flat to the roof to minimise aesthetic impacts and the inverter and control switchgear was all roof mounted in a common area. This project featured ABB/PowerOne inverters which are great when multiple arrays facing multiple directions are required. We also fitted a SolarLog monitoring system which allows the owners and MGA Solar to monitor the system in great detail and get fault alerts if anything goes wrong in the future; and important part of our after sales service offer.

Astute readers will also note the extensive use of safety equipment in the image gallery. We take the safety of our staff very seriously and in this case used guard railings and kick boards to protect residents and visitors to the site too.

Another great solar project for the Shire!

99kW Shoalhaven Heads Community system

Shoalhaven heads is about the most gorgeous place we could think of to do an installation. To top it off, it’s home to one of Australia’s first community owned solar systems.

The project, dubbed Repower One, is being driven by Repower Shoalhaven, a community group formed in 2013 to spearhead the south-coast NSW town’s transition to sustainable energy systems.

The 99KW system is the largest community owned solar system in Australia offering everyday investors a 6.5% return for a 10 year period and the chance to help out the local bowling club, who will be gifted the system after 10 years of community ownership.

Installed in conjunction with Sunny afternoons and Southern Cross Solar what a lovely job for a lovely community. This system was featured in RenewEconomy which you can read about here.

100kW Batemans Bay Soldiers Club system

Businesses of all shapes and sizes across Australia are turning to  solar to reduce operating costs and Batemans Bay Soldiers Club is no exception.

Due to the complex roof structure the solar system had to be installed across multiple locations including cured, flat and tilted sections. Challenging; yes but all in a  days work for MGA Solar.

Being on the lovely South Coast of New South wales it’s located close to the water and exposed to occasionally extreme weather conditions. Our mounting systems therefore had to be very robust and properly engineered to cope. We also helped design and install a custom shelter for the inverters and associated switchgear to ensure they have  a long and trouble free life.

Installed in conjunction with Sunny Afternoons and Southern Cross Solar this project was very time consuming but lucky for us a cold beer in the afternoons wasn’t far away.


160kW Wollongong University system

The Sustainable Buildings Research Centre is located at the aptly named Innovation Campus, Wollongong University.

The centre has been established to provide a hub for Academia to create, develop, and implement cutting edge sustainable building concepts and the building is on its way towards a 6 Star Green Star rating.

Logically, the centre chose to install a solar system, but true to their innovation mandate it’s no ordinary system.

The system was installed by MGA Solar in conjunction with Energy Matters, one of Australia’s largest solar company’s. The projects provided many technical challenges in design, installation and material restrictions, pushing the boundaries of commercial system design. The installation included roof and facade mountings and we are hugely proud to have been involved.

The system was a finalist in the 2014 Clean Energy Council’s Solar Design and Installation award, testament to it’s innovative nature.



20kw Sea Breeze Apartments system

The Sea Breeze Apartments  were formerly known as “Your Horse and Cart”, a favourite drinking hole I frequented as a young man looking for that special someone.

Recently converted to apartments, solar was a natural part of the upgrade. Today, the facility is a modern luxury apartment block with five floors and amazing views up and down the gorgeous Georges River.

Being highly exposed to westerly wind that accelerate up the terraced apartments, the fixings in the mounting frame had to be carefully designed and installed to meet wind loading requirements.

The Spanish Terracotta tiles had to be specially ground and modified to accommodate the brackets making it a very tedious, time consuming job but well worth it for the view you got at morning tea on the roof

looking down the river.

100kw CMPS Pty Ltd system

When taking on a system of this magnitude there is a lot of planning and negotiating with local utility’s, engineers, designers and of course the client, also with recent changes in the Australian standards there were many issues to consider.

Working together with BTS Energy we were given the task of putting 400 panels on an east and west facing aspect and due to engineering confinements weren’t able tilt the system, the roof had a 10 degree pitch and when facing the panels to the East or West you lose about 13% efficiency but the size of the system more than compensated for the loss.

After months of planning , 4 weeks on the job and a lot of very hot summer days on the roof the job was complete and is now producing on average over 400kw/hrs a day putting a major dent in CMPS’s energy bill and is looking to pay itself off in about 5 years.

10KW KCST Composites system

After being given a relatively easy looking job at CST Composites Kurnell to do, the owner informed me of the high winds associated with the site.

Kurnell is on a peninsular of land between Botany Bay to the west and Bate Bay to the East. With the excessive amounts of sand mining over the last 2twenty years, Kurnell has been left exposed to winds from all directions with little or no natural or man-made structures to diffuse the winds ferocity.

The factory roof was sloping to the east and to the west with a very minimal pitch so a tilted system was needed and luckily for the owner of CST, the roof structure was very robust. Of course, we went through all the relevant engineering approvals, to make sure.

After consulting with engineers we decided to go with the Sunlock tilting system, an Australian produced product with more than enough options and technical backup to do the job.

Since the job was completed 2 years ago Clive has received winds in excess of 90 km/hr on several occasions and nothing has budged.

Clive is now considering putting in another 10 kW System on his eastern roof.
