thats exactly what they all want, keep the demand for power as it is and make $$$ from solar installs as well. The key is to do it backwards , work out what sized system you can afford and the 1.5KW are the best priced because the recs credits are peaked at that. This is why a 1.5 can cost say $2000 and a 3kw will be $8000. Its because you get less rebate on the 2nd 1.5KW than the first.
So put in the 1.5 understanding it will never meet your current usage then do what green energy is all about ,reduce your power usage. when the inverter dies on the 1.5KW system strip the panels and sell them for more than the system cost you in the first place. with a 1.5KW system you are paying way less than the sum of the equip. the Govt is paying the rest. Or install a batt bank . I did ask if they would still give me a rebate if i complaetley powered my home with the 1.5K/W system by using dc appliances. which is very green, but apparantley thats not the intent of the solar rebate scheme.?
The power companies do not want everyone with 5KW on thier roof or they will be bill free and thats no good so they convinced Govt to curve the recs credits at an amount that they thought feasible whilst still protecting profits and 1.5KW is the lucky number.
I have seen them for as little as $1200 installed. that will pay itself off quicker than a big system and will help to reduce your bill without outlaying to much.
I know of people paying interest on loans to install big systems this is just crazy to me. If I had a lazy 10K I would put in a term dep and pay for the elec price hikes with the banks interest not me pay for power companies infustructure so they can claim Green energy cred with govt and onsell my solar generated power to someone slse for a premium price. And I still have my capital.
If i ever do install it it will be a 1.5kw system as the govt will pay more than me. so if they cut the system they loose to. In the meantime I am just using less just like fuel ,when it goes up you find ways to use less.
This is just my opinion and like LPG on cars it works for some and for others they can't see the benifit given the outlays. one thing you can be assured of is the solar rebate scheme was not designed with our benifit in mind.
I don't want to sound against it , but consider all the facts and never sign up with the sales guy in your lounge room.
Kind regards
