Solar for iconic town hall - with 30 degrees of difficulty
Brunswick Town Hall is an iconic Melbourne landmark which was built in 1876 and
only survived the wreckers ball in 1974 after a local protest campaign and
although it earns its keep today as a popular social venue, it was one the top
ten energy users in the municipality.
This did not fit well with Moreland Council which was the third accredited
carbon neutral council in Australia, but installing solar panels on the three
storey historic building with a 30 degree slope on its corrugated iron roof
presented some difficult installation problems.
Installers Envirogroup also faced the need to overcome the problem of potential
traffic disruption, as the location of the Town Hall on Sydney Road, Brunswick
is one of Melbourne's busiest arterial roads. Safety was also a major
requirement and required the installation of safety rails on the roof and
harnesses for all the installers.
The main roof area was also found to be insufficient to house enough
conventional solar panels to generate the required energy level of 100kWp and
using the lower roof area was seen to be inefficient as it is subject to
shadowing for part of the day.
The eventual solution was to use the new High Efficiency PERC Mono Trina Solar
290Wp panels are more efficient than conventional panels.
The final installation used 345 panels on the main roof which will generate
111kWh per year and provide a greenhouse gas offset of 13,981 tonnes or 33 cars.
To get the same energy output with conventional 260Wp would have required more
than 400 panels.
The more efficient panels not only reduced the number of panels that were
required it also reduced the installation time as well as obtaining more energy
out of the roof space.
According to lead electrician on the install, Nick Garric it was the most
difficult job he's tackled in the seven years he has been an installer.
"Our installing team members were in safety harness for the four week
installation period and because of the number of panels, we had to lay them in a
landscape pattern, rather than the usual portrait configuration.
"This meant our roof access had to be up the 30 degree slope, rather than along
"Because of the age of the building and the roof, another difficulty we had to
overcome was in running the cables from the panels to the inverter.
"Clearly the 290Wp panels were the solution for us to get enough panels on the
roof to generate the required level of energy and we had no handling
difficulties compared to the standard 260Wp panels.
"Being on a 30 degree slope the panels are largely self-cleaning, whereas if we
had to use the lower flat roof areas there would have been significant soiling
as the traffic in busy Sydney Road generates a high level of road grime," Nick
Trina Solar Sales Manager Govind Kant said that the Brunswick Town Hall
installation is the first use of the 290Wp solar panels in Australia.
"Although the standard poly modules still have a niche market, the rapid
improvement in efficiency with mono modules coupled with the minimal price gap
between the poly and the mono modules, will soon see mono modules becoming main
stream. The extra price on the mono modules is offset by the greater savings on
the balance of the system," Govind Kant said.
