Solar Panels Sydney: Compare Prices & Installers

Sydney holds one of many main set up charges for solar energy the world over. In reality in sure suburbs of Sydney (equivalent to Schofields) the info from the Australian Photovoltaic Institute exhibits that over 70% of the rooftops have a photo voltaic panel set up. This text goals to take a look at the funding case for photo voltaic and gives a information on the way to decide on solar energy in Sydney.

When you’re occupied with solar energy to your Sydney-based enterprise, see our article on Industrial Photo voltaic Energy in Sydney.

How a lot energy do photo voltaic panels generate in Sydney?

Though it is probably not as sunny as Brisbane or Darwin, Sydney remains to be receives loads of solar hours. With NREL’s PVWatts calculator we will see that for every kWh that’s put in in Sydney you must be capable of generate a median of three.96 kWh per day. This elements in a system effectivity lack of 15% which might be typical of an inexpensive high quality Sydney photo voltaic system.

We’ve put collectively the under desk of widespread system sizes that will help you perceive what this implies. It’s useful to keep in mind that kilowatt-hours (kWh) are the models that seem in your electrical energy invoice – and which your electrical energy retailer makes use of to calculate your quarterly or month-to-month electrical energy prices.

What do these numbers imply for me if I’m going photo voltaic?

Solar energy is a good funding for just about any residence that has a reasonably-sized, unshaded roof and a few electrical energy consumption through the daylight (see the sections under). It is because your home-generated photo voltaic power can prevent cash in two methods:

1. Photo voltaic helps you cut back the quantity of power you should buy out of your electrical energy retailer / the grid. That is generally known as ‘photo voltaic self-consumption‘, and it’s the key to taking advantage of your photo voltaic system – you must do every thing you’ll be able to to maximise your self consumption. In follow, self-consumption entails working your home equipment (pool pump, washer, dish washer, and many others) when the solar is shining. (Learn extra about shiftable hundreds.)
2. You may earn credit in your electrical energy invoice to your system’s surplus power. That is often known as a photo voltaic feed-in tariff. Any photo voltaic power produced that’s not instantly put to make use of in gadgets in your house will routinely be despatched again to the grid, incomes you a feed-in credit score. A couple of years in the past, feed-in tariffs had been state-sponsored and fairly beneficiant; nowadays the charges supplied are a bit decrease however nonetheless sufficient to assist make photo voltaic a gorgeous funding.

The worth of your photo voltaic power relies on a mixture of how a lot you self-consume and the way a lot you export. In case you have a 6.6kW of photo voltaic panels in Syndey that produces a median of 26.1kWh/day, however you solely handle to self-consume 20% of that, then your financial savings will probably be smaller than in case you managed to self-consume 40% – and even, ideally, 60%.

It’s due to this fact essential that the system you select is appropriately sized to your residence and electrical energy consumption. Now we have developed a instrument that will help you choose a photo voltaic PV system dimension based mostly on the quantity of power that you simply eat and your consumption sample.

What photo voltaic rebates can be found in Sydney and NSW

Federal STC Rebate

Like everybody in every single place in Australia, Sydney residents who set up photo voltaic can profit from the nation’s small-scale know-how certificates (STC) rebate below the Renewable Energy Target. In easy phrases the STC rebate provides an upfront low cost of roughly 30% for any photo voltaic set up below 100kW in capability in Australia. The rebate does differ barely relying in your places in Australia and on the present market value for the certificates it produces.

The rebate is designed to be collected by the corporate who installs your photo voltaic system, so that they in flip give you a internet value which has deducted the STC rebate. Most quotes will present a breakdown of the full prices (earlier than the rebate) and the online value to you (after the rebate).

To offer you an instance, a typical 6.6kW photo voltaic panel system in Sydney would generate 82 STCs (utilizing the Clear Power Regulator’s calculator) and at a present value of $36.9 per certificate that will end in a rebate of $3,026.

NSW Authorities curiosity free loans for batteries

The NSW authorities has launched a program to offer interest-free loans to clients putting in a battery. The scheme is simply obtainable to residents who’re in one of many postcodes listed on this web page, largely protecting the Hunter Valley and Blue Mountains areas.

We offer some data on the monetary return of photo voltaic batteries additional down this text, nonetheless in our view at Photo voltaic Alternative an interest-free mortgage is just not enough to vary the financial story of putting in a battery.

How a lot do photo voltaic panels value in Sydney?

Thanks partly to the federal incentives defined above, Australia is residence to a few of the lowest photo voltaic PV system costs on this planet – which is without doubt one of the causes that so many properties and companies have photo voltaic panels put in. Photo voltaic Alternative has been maintaining monitor of set up value traits since 2012 and as you’ll be able to see within the under desk the price of photo voltaic in Sydney tracks carefully to the nationwide common.

The chart under exhibits how costs have modified (by way of {dollars} per watt of capability – $/W) since 2012 for a variety of common system sizes. On common photo voltaic system costs in Sydney have greater than halved since we began publishing figures.

In line with our information from March 2022, a typical 5kW system in Sydney prices about $4,450 on common after the STC rebate has been deducted.

Pricing will range relying on if any further prices are concerned like tile roof installations or tilt frames. Photo voltaic Alternative’s on-line quote comparability instrument features a comparability of all of those further prices which could apply to your property.

What’s the monetary return for a photo voltaic panel system in Sydney?

The brief reply is that there’s a nice return on funding for Sydney properties with the power to save lots of as much as $2,707 per yr in your power invoice with a typical payback interval between 4 and 5 years.

The desk under exhibits payback intervals and annual financial savings within the first yr for a Sydney photo voltaic panel system for a a number of totally different situations. Observe that we’ve tried to match the system dimension to the power utilization, nonetheless the proper dimension system additionally is determined by what time of day power is used inside a house. The self-consumption price of 40% signifies that an inexpensive quantity of energy is getting used in the midst of the day.

As we’ve used common costs from the Photo voltaic Alternative Worth Index, the monetary return may very well be higher for you if you’ll find a less expensive quote. Though be cautious of quotes which can be too low-cost as workmanship, gross sales and set up course of and high quality of merchandise can drop away in a short time.

Assumptions/limitations of this evaluation

• Assumes an electrical energy value of 23c / kWh which is in direction of the center of what’s supplied in Sydney
• Assumes an uncapped photo voltaic feed in tariff of 9c / kWh which on the higher finish of what you’ll find in Sydney
• Common prices come from the Photo voltaic Alternative Worth Index for March 2022
• Your self-consumption price will range relying on how you employ energy in your house. At greater price, means much less energy is exported to the grid and improves your monetary return

What about photo voltaic battery storage in Sydney?

The price of photo voltaic batteries in Sydney is way greater than the fee to put in photo voltaic panels. Though the battery performance has been nicely established and there are totally different manufacturers available in the market, the return on funding nonetheless leaves one thing to be desired.

At Photo voltaic Alternative, we’ve been monitoring the prices of photo voltaic batteries within the battery value index and usually performing an evaluation of the monetary return of batteries. We take a look at 3 typical use circumstances for photo voltaic batteries and alter the scale of the photo voltaic and battery answer to suit. See the under payback intervals and annual financial savings from photo voltaic and batteries in Sydney.

To evaluation our assumptions and the methodology of this evaluation see our full article.

As most batteries have a guaranty for 10 years, our evaluation means that the battery won’t be able to pay for itself throughout its lifetime. There may be nonetheless fairly a solution to go on the price of batteries earlier than this story will change. Beforehand we’ve estimated that batteries might want to value $200-$300 per kWh of capability to supply a very good return on funding whereas the present value is round $1,000 to $1,100 per kWh.

This evaluation does ignore a few of the non-financial advantages of batteries. Crucially as Australia is experiencing greater frequencies of flooding and extra extreme bushfires many households are interested in batteries to offer back-up energy within the occasion of the grid outage.

There may be additionally the profit to the surroundings to help within the discount in Australia’s reliance of coal-fired energy stations. Batteries, and lots of of them, will probably be required if we’re going to remove fossil gasoline energy in Australia altogether.
