Digivation Hack Central

Ever since the Victorian government introduced the NET premium rate tariff of 60c/kWh exported, I decided that a PV system was economically viable. Green issues were not considered.

Using various methods, I found a 5kW with our daily usage of 20kWh system should return about $3500 per year using AGL’s generous 68c PFIT.

As per usual, got many quotations and settled on one with Glen Clark and Co. I decided to keep the REC’s.

Specs are

28 * 175 watt Solar Panels (Mono Crystalline) TH175M
1 * Aurora PVI-5000-OUTD-AU Solar Inverter

I did want thin film amorphous but it came out at $5k more, so even though they have better performance in low light and higher temperatures (PV panel temperature derating) which works out to about 10%.

This gives 4.9kW for A$25k without RECs. Ill have to recover the RECs later when hopefully the price will be a bit more than they are now. More on this later.

This should pay back in about 5 years, with a return of about 20% on investment after the RECs have been accounted for.
