Given the amount of money you are about to spend on your solar system and the lifetime expectancy you want in return, there are a couple of factors you should take into consideration before purchasing your solar system.
If you want your solar system to last and perform its best, any electrical wiring installation should be done by a licensed electrician (as it is required by law). A CEC (Clean Energy Council) accredited installer should also be supervising the install. Ideally the electrician and the CEC accredited installer will be the same person and should have identification to prove such licenses and accreditation.
Below are some examples of good and bad installations:
1. The quality of solar panels and inverter will mean little if they are installed incorrectly and not to manufacturer’s specifications. Warranties may be void if the manufacturer’s installation guidelines aren’t followed, leaving you to foot the bill if the solar company is no longer around. For example:
2. Another often overlooked but very important part of the installation is the water ingress protection of your roof. If you don’t want any leaks, then it is very important your installer uses best practice and appropriate materials for cable entries and fixing the brackets to your roof.
3. Cable support is another factor that gets overlooked, and some shortcuts can be taken. The cable should be supported at regular intervals, so there is no added stress due to sagging. The method of supporting the cable should be done in a way so that it will last as long as the system, e.g. 20 years. Cables dangling in the breeze and sitting on the roof will ware through their insulation over time.
