This 4.465kw solar power installation in Greensborough features 19 x 235 watt Lightway OP+ panels with a 5kw Effekta inverter.  We were able to both maximise the size of the system using available roof space and stay within SP Ausnet’s limit of 4.5kw systems (larger systems require pre approval).

Hard to see, but this 1.9kw solar power installation in Kyneton features possibly the best panel in the world: the Sunpower E19 series 318 watt panel along with a SMA 2500HF inverter.  These panels rate a total panel conversion efficiency of 19.5%.  We look forward to a future in which Sunpower becomes more competitive on pricing so that these panels are within reach of more solar buyers.  Above the Sunpower Panels is a 22 Tube Apricus Evacuated Tube Solar Hot Water Servides also installed by Leeson Solar. The guy in the Leeson Solar shirt on the left is none other than Peter Lesson who founded on the company on the principles of using quality gear and offering superior customer service.

The two photos for a 5kw solar power installation in Kealba once again faces the problem of how to fit 20 panels in a limited roof space.  The West facing array has two strings of 7 panels each and the North facing array is 6 panels.  This will maximise production given the roofing configuration for the 20 x 250 watt Trina Honey panels and 5kw Aurora inverter.

The design for this 4.23kw solar power installation in Coburg was interesting. How to maximise the number of panels while avoiding the shadow of the evaporative cooler in the centre.  Using multiple aerial photos,  trigonometry calculations and input from the client we selected a placement in which during winter months the shadow would fall in the centre gap of the front row of panels.  That way voltage would not be impacted by shade.  If the extra two panels had been installed the overall shade impact would have lowered the annual production of the system and therefore was not a good option for the client.

This 2.55kw solar power installation in Forest Hill went through several designs in order to install the maximum number of panels on the North face.  There are 6 panels on a shared garage roof on tilt frames, 4 panels on the house roof with the corners just overhanging the ridge line, and finally the last panel in landscape position above the solar hot water.  Panels are 255 watt Trina Honey and the inverter is SMA Sunny Boy 3000TL. The TV Antenna in the foreground was removed by Leeson Solar Communications licenced cablers.

The client for this 5kw solar power installation in Rosanna was able to achieve an incredible feat: she got three different solar power companies to offer her the same system design using 26 x 190 watt Trina panels and a Fronius IG TL 5kw inverter.  Once she could compare the companies on effectively the same job she was able to make an informed decision on which company would best suit her needs.  Why did she choose Leeson Solar?  Because we are local to her (6km from our factory), we use our own teams for installations never using sub-contractors, and when she checked our references she got a glowing recommendation from Mother of God Primary School in East Ivanhoe.  Leeson Electrical (our commercial division) has done extensive work at Mother of God, Ivanhoe East Primary, and St. Bernadettes all in Ivanhoe.

3.96kw solar power installation in Surrey Hills on tilt frames on a single story roof.  To the left (out of picture) is a second story structure that casts shade onto the roof space in the left.  That is why the rear two (or Southernmost) rows have four panels each while the front two (or Northernmost with one out of the picture) have five panels each.  The design was created after shade analysis with the client.  We use a variety of sources including on site evaluation to determine shade patterns for a given installation site. If you are considering solar, start to record shade patterns at 10am and 2pm at the Winter Soltice.  The hours in between provide the strongest power generation times and are the first consideration for shade analysis.  Outside of this time is also important, but usually sees a much lower production of power.

The above two pictures are for a split array 4.08kw solar power installation in Ferntree Gully using 16 x 255 watt Trina Honey panels and a SMA Sunny Boy 4000TL.  In order to maximise the roof space notice that the top rows of panels are in portrait position while the bottom row is in landscape position.  There is still a significant gap at the bottom so that any water running off of the panels will have a chance to feed into the rain gutter (as opposed to running over the side of the house).  We take pride in our ability to maximise the use of available roof space with our solar panel installations.

This is a 2.6kw solar power installation in Ivanhoe.  Notice the pool in the background?  Pool pumps can consume up to 3,500 kwh per year.  About half of the people that we talk to about solar power have pools driving up their power bills.

This 2.6kw solar power installation in Carnegie was challenging because while the house was fairly good sized, the roof was chopped up into lots of space faces.  I think the architect may have been overly creative.  Getting these panels to fit was a challenge as was getting the measurements on a second story roof.  The panels are Lightway 235 watt OP + with an Effekta 3kw inverter.
