Below, you will find answers to common questions we receive from architects and building planners.
What is the optimal roof direction to generate solar power?
When designing a roof, it’s important to ensure there will be enough space for solar panels to make it a worthwhile investment. In Australia, the rule of thumb is to face solar panels to the north to maximise solar power generation.
What is the best solar panel for a flat roof?
For flat roofs, we recommend SunPower solar panels. They are a Tier 1 panel and lying them flat does not affect your warranty. While panel manufacturers generally recommend or insist on tilting the panels in their warranty guidelines, SunPower specifically state that you can install their panels at any angle, from horizontal to vertical, without affecting the warranty.
What are the location restrictions for solar battery installations?
For a home that plans to have solar batteries, it is highly critical you mark out a location suitable for a solar battery installation. This is because there are strict rules on where and how a battery can be installed.
For instance, solar batteries cannot be installed on flammable material which backs onto a habitable room. The battery location requires a clearance area of 600mm on either side of the battery and 900mm above the battery. This includes clearances to windows and doors to habitable rooms.
What are the relevant Australian Standards (AS) for the design and installation of solar systems?
To ensure a solar system has been installed safely, the following AS must be adhered to:
- AS 5033 Installation of PV arrays
- AS 3000 Electrical wiring rules
- AS 1768 Lightning protection
- AS 1170.2 Wind loads
- AS4777 Grid connections of energy systems via inverters
- AS5139 Battery Energy Storage Systems (BESSs)
As a CEC-accredited solar installer, EnviroGroup is well aware of these standards and we review them regularly.
Regulations and best practices evolve over time. To ensure all our installations are in line with current requirements, EnviroGroup remains on the forefront of any upcoming changes.
An industry leader, you can be rest assured that we will provide you with the most up to date information and advice.
