Good Solar Systems

A good solar system is made of premium parts.
Choosing the best technology and the best quality ensures that the system lasts decades and that it offers the best return on the investment made.

There are many brands and many technologies available in the solar panel market. At Blue Green Engineering, we carefully consider the panel efficiency and system yield as part of our design process. The system yield is vital, as it defines the energy output of the system and, therefore, the cash it can generate. Higher efficiency panels offer more power for the same unit of area. Hence, using high efficiency panels is important where space is limited.

Blue Green Engineering uses industry-leading high performance mono-crystalline silicon cells in panels from Suntech, the world’s largest panel manufacturer. Suntech panels are independently certified as meeting international quality standards and are backed by with a 25-year performance guarantee. Suntech solar panels are a commercialisation of Australian technology developed by the University of New South Wales (UNSW) in Sydney. Therefore, when you buy Suntech, you’re buying an Australia innovation.

Apart form choosing quality solar panels, Blue Green Engineering carefully also considers each element of the system in order to create a quality generation unit. We use European inverters of the highest available efficiency, always more than 91%, so that the most is made out of the system.

A good solar system is well designed.
Blue Green Engineering designs to minimise losses. Such design includes reducing wiring losses and limiting the impact of shade on the system. 

The ideal design option is to face panels north and to pitch panels at an angle of 30 degrees. Our engineers assess the conditions of each roof to design framing that will position the panels as close to these ideal parameters as possible. Our software analysis also contributes to create an optimised design for you. We have so far delivered to a range of design criteria for our clients, be it budget based, aesthetics based, or having to do with keeping the system safe from inquisitive wildlife! Finally, our preliminary analysis always includes detailed financial and technical analyses, so that the client can make an informed decision and be confident in our recommendations.

Proper installation is key to a good solar system.Blue Green Engineering installations are designed and project managed by our Clean Energy Council accredited solar engineers, who are graduates of the world leading School of Photovoltaic and Renewable Energy of the University of New South Wales (UNSW) in Sydney. Moreover, our installation teams are licensed electricians and Clean Energy Council certified installers.

A good solar system is tailored to the client’s expectations.At our first consultation, Blue Green Engineering establishes your expectations from the system. Our engineers then base their designs on these expectations in order to create a truly optimal system for you.

There are many influencing elements in solar design. Blue Green Engineering can provide a number of creative solutions to balance such elements even in cases where premises are located in challenging locations. We can design to maximise system size or to offset a specific range of power use. If a certain aesthetical outcome is desired, Blue Green Engineering can also design based on this.

Beware of cheap, inferior systems

• A 1kW cheap system does not offer the same performance as a 1kW high quality system.
• Cheaper, no-name panels are manufactured from inferior quality silicon, which may lead to an earlier degradation of power output.
• Non-established panel manufacturers may offer competitive warranty periods; however, the manufacturer may not be there for the duration of the warranty.
• Cheap, low quality inverters are noisy, need to be replaced sooner and have low efficiency, which also translates to lower system output.
• Quick and cheap installations do not always consider site conditions, such as the shading effects on and orientation of the panels: if shading effects are not considered in the design, the system will not perform to its full potential.

Understand what the numbers mean in a practical sense

• A solar panel system with high efficiency requires a smaller roof space. For example, a highly efficient 200w panel system produces the same amount of energy as a low efficiency 200w panel system which takes up more space.
• High yield panels produce more energy than low yield panels. For example, a 200w high yield panel produces more energy than a 200w low yield panel.
• A high efficiency inverter ensures that your system produces more energy. For example, a highly efficient 2kW inverter produces more energy than a 2kW low efficient inverter.
