The airwaves are currently pulsing with more warnings about possible dangers in products used in the Federal Government’s green home schemes. While there is a lot of talk, the Clean Energy Council has today reassured everyone that there have been no cases of solar panels causing house fires.
We are fortunate that in Australia our building and electrical works are governed by good industry standards. What is unfortunate is that there will always be cowboys willing to duck under the minimum standards set by industry and government. So how do you know if your solar power installation has been done properly?
Solar installations are technical and complex, and solar panels all look pretty much the same. Unless they are an electrician, it is unlikely that the average person is able to adequately judge the quality of a solar installation. You will always have to trust your installer and rely on their integrity.
Here’s a guide to assuring yourself you are getting a quality job:
Your supplier and installer must be a licensed electrician accredited by the Clean Energy Council. They will appear on the CEC’s database on their website . Furthermore, established and reputable electricians display their reputations by their dress, manner, equipment and vehicles.
Approved panels and inverters are listed on the CEC’s website.
Brand names provide customers with quality assurance. We have always supplied high-quality brand-name equipment: our panels are either Sharp or Suntech, and our inverters are either German-made SMA or Australian-made Latronics.
Make sure you get a warranty. Our solar panels come with a manufacturer-backed 25 year power output guarantee that ensures the panel will be performing at 90% of its stated output after 12 years and 80% after 25 years. Inverters from Ingenero are backed by a full product replacement warranty of 10 years. The balance of system components used are high quality, ensuring low energy loss, and are rated to meet or exceed Australian standards. If anything we sold becomes defective or breaks within the first 10 years, we come to you and fix it or replace it.
If you have concerns about the quality of your installation we suggest you pay for a second opinion from one of the installers accredited by the CEC.

We’ve done some analysis on the differences between gas hot water, electric hot water and solar hot water systems and the results are telling.
Electric hot water is five times more expensive than electric-boosted solar and 10 times more expensive than gas-boosted solar. Electric hot water also produces more than 14 times more greenhouse gas emissions than gas boosted solar hot water.
