Good article, although long and I can’t guarantee I read every line in my lunch break.

I recently installed a 1 KW system on my house. My net cost was about $2,500 (so $10,500 total) and that’s without selling my RECs. (There are some quite sound arguments why you might choose not to sell your RECs. A recent issue of ReNew magazine covered this.)

I bought my system as part of a buying collective of 150 households organised by Local Power in Brisbane. As far as I’m aware the components are all good quality.

With Green Power, as long as the aggregate usage by Green Power buyers is less than the mandated target, no extra renewable power will be generated.

By installing solar panels, and not selling my RECs I’m creating extra renewable energy production right now. (That is to say, more than would otherwise occur).

My system will definitely pay for itself over its lifetime, especially if recent mooted power price rises happen. Not a huge rate of return, but better than the share market recently.
