Quality & Value
Those two words sum it up.
We only use components that stand out from the crowd. Our recommended system uses:
Our aim is to get as much high quality PV connected to the grid as possible. By installing many systems we don't need excessive margins on any one of them.
With the highest quality components we use we might not be able to match pricing of the very cheapest systems out there in the market. But if you want quality that lasts at the best possible price, talk to us!
Given the currently available government rebates we recommend the following:
After accounting for rebates and RECs The government cash rebate PVRP, $8 per Watt, capped at $8000. RECs currently trading at $40 each, total about $800, but price is variable and fluctuates with demand and supply. Both can change at any time without prior notice. For more details follow the above links. and including Western Power fees Synergy/Wester Power charge an application fee of $107 before they check an application for the Renewable Energy Buyback Scheme (REBS). Once approved in most cases a meter upgrade to one of their smart meters will cost $205. If you already have a smart meter, it can be reprogrammed for $66. If you have a 3 phase meter, the upgrade would cost $655. Prices subject to change, the above numbers were verified on 23/3/2008. a home owner will usually be out of pocket from $4000. Costs can vary between installations for a number of reasons. For example houses with 3 phase power supply will attract Synergy fees of $655 for a meter upgrade, while upgrading a single phase meter costs only $205. The length of cable runs influences labour and materials required by the electricians. Old electric installations might require some upgrades, etc... All that makes it inevitable that we have to do a site visit before we can give you a detailed fixed price quote. The expected power generation for a north facing roof would be about 1710 kWh/year. At current power prices Synergy A1 tariff, $0.1394/kWh incl. GST, correct as of 23/03/2008, assuming you export less power than you import per billing period that amounts to a saving of $238 per year. Even without inflation of electricity prices a grid connect system would pay its cost back in 17 years.
With adoption of the Kyoto protocol and global energy shortages, rising energy and especially electricity costs are very likely. If electricity prices rise just 5% p.a. in coming years, the payback time for your system is reduced to 12.5 years.
Yesterday's (29/1/2009) news about massive increases to WA electricity prices comes as no surprise. Assuming price rises as requested by the Office of Energy, your system will pay back its cost in less than 8 years.
An even better situation would arise if feed in tariffs, which successfully boosted PV installations all over Europe and in parts of the US, are adopted. Some Eastern states have already passed legislation in this area. The WA Liberals promised to introduce a feed in tariff and are currently working on the details. A feed in tariff means that power you generate from clean sources and deliver to the grid will earn you more than the usual price of grid power.
A grid connect system in Perth will reduce CO2 emissions by a huge amount, more than in most other locations around the world! That is a result of both the 'dirty' coal fired power we use here combined with the huge amount of sunshine we receive. Our recommended system can help avoid 1,675 kg of CO2 every year. That is the same quantity produced by a small car running over 10,000 km.
