Yeh sorry I did get off the topic.
Answer - one that has impecable reputation, been installing Solar long before the State Governments across Australia introduced a "Solar Rebate Scheme" (this weed's out the cash cows that start up business's to take advantage of polititian criminal schemes) and yeh lots are still installing.
INSTALLERS -
I would be looking for a installer that still operates a reputable licenced Electrican business, does not soley install Solar ONLY.
This gives surity if their is a problem with your Solar System the business is operational, insured and highly likely will still be in business for years to come.
BRAND NAME SYSTEMS -
The product of choice should be Tier 1 rated, the manufacturer of the product should have a long standing operational business in Australia for certainty of warrant claims, parts, longevity,etc.
I can name approx 5 Solar Manufacturing business's operating within Australia that would fit this mould.
Most Panels and Inverters are imported by Solar Shops direct, cause they get the product cheap and can on sell at higher margins. Remembering that Solar Shops go out of business and the manufacturer is in another country.... You get the drift. Lets face it these systems are tooo expensive to start with.
Also consider the Origin Energy, AGL, TRUenergy are good options for Solar Systems, they all buy quality systems and their business is not going anywhere. Installers are contractors though??
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.
Yeh you did mention REC's also known as Renewable Energy Certificates, My reference is relating to this - thats dribble mate.
I will be the first to put my hand up and say how I kick myself for not installing Solar when the NSW State Govt was paying people to install Solar at home, gauranteed money until 2016.
For my scenario, I personally don't see value in investing in Solar at todays Regulated domestic Electricity Tariff's. So I have no Solar system.
Family of four in a 3 - 4 bedroom home....to make any real impact to your power bills would need a 5kW system.
A good system of this size will be >18K, return on investment tooooooo long..
Hey if you want to put on 1.5kW system to feel good and give you a warm fuzzy fealing, great, but its a waste of money with little impact in your Electricity costs.
With regard to the wider economic arguments, I look at photovoltaic on roofs as distributed power generation - if you removed that capacity, we'd need to replace it with some other form of generation. And building power generation, even if privately owned still has a cost to the country - prices / tax offsets etc.
I agree with Jetcrew in that there needs to be much more emphasis on reducing demand - we're also trying to do that, as it has a cash benefit as well as environmental.
Yeh I don't realy agree with you db.
Most Solar sytems people instal don't even cover their own Electricity usage let alone offer Power Generation for the National Electricity Grid. Ontop of this for Solar to make any real impact in decreasing Demand on the National Electricity Market most of the Domestic population in Australia would need to have Solar operational on their roof tops. Which is never going to happen.
This is exactley the same thinking by the Govt when they saw Domestic Roof Top Solar as the answer to Electricity Demand. They intro'd a Rebate Scheme to entice people to put Solar on at home knowing the "Majority" needs to act to have any real effect. Well... here we are. Over 20% increase in the Domestic Electricity Tariff in 2010/2011 period, with more increases expected for the next 6 years, The Number 1 contributor to this..... The Solar Rebate Scheme.
I don't hear any positive news or data that Demand has decreased because of Roof Top Solar - Have You?
The biggest Demand hungry item iinstalled in houselholds is the Air Conditioning Unit. If you want to realy reduce demand on both the Network side and Electricity Generation, don't use your Aircon. Fat Chance Hey....
