Can An Installer Change The Quoted Price Of My Solar System?

The STC price has plummeted and pushed the price of solar up. What should you do if you’ve already accepted a quote and the installer wants to increase the price?

I’m going to ask you to imagine preparing to buy a rooftop solar system.  I want you to see yourself working hard, saving your money, doing your research, and getting yourself some quotes.  After careful consideration, you decide upon an installer, sign the contract, and transfer a 10% deposit to them.  At that point you would be looking forward to saving money on your electricity bills and doing your bit to help the environment.

Now imagine how you’d feel if, before the day of the installation, the installer contacts you and says the price has gone up and you now have to pay $1,000 extra.

I imagine you wouldn’t be very happy about it. [Read more…]

Will LGCs Pay More Than STCs on a 10-100kW solar system?

There are 2 subsidies for solar under 100kW: STCs (AKA the ‘solar rebate’) and the lesser known LGCs. Which one will give you the better return?

Update 23rd Feb 2018: Solar installations of 100 kilowatts or less now only receive STCs.  However, applications made before March 31st 2018 for systems of 10 to 100 kilowatts may be accepted under the old rules and permitted to receive LGCs.

Many people are aware the Renewable Energy Target, or RET, lowers the cost of rooftop solar.  This is often called the solar rebate, even though that term is not entirely accurate.

But what few people know is, provided their system is large enough, they have a choice in the type of assistance they receive.  A household with a 10 kilowatt rooftop solar system can either accept Small-scale Technology Certificates (STCs) or Large-scale Generation Certificates (LGCs).

Almost all solar systems 100kW and smaller, currently being installed use STCs because they are all deemed immediately after the installation whereas LGCs are deemed annually over 15 years.

At the time of writing (July 2016) STCs are $38 each whereas LGCs are at a sky high $82. This has made some savvy solar installers wonder if using LGCs instead of STCs might create a better return for patient solar owners. [Read more…]
