Solar power system prices have fallen significantly in recent years in Tasmania, as well as throughout Australia and the rest of the world. It is for this reason that installing a solar power system in Hobart (not to menion the rest of Tasmania) is a good investment for the right homes & businesses. This article is an overview of what you need to consider when looking into getting a solar PV system in Tasmania, including pricing, incentives and system sizing.

Benefits of solar power in Hobart: Generate your own electricity

The first step in finding the best deals on solar power is understanding its potential benefits to a home or business. Solar panels only produce power when the sun is shining. Depending on the climatic conditions of the location in which a solar system is installed, the amount of sunlight varies. Although Tasmania is not as sun-blessed as the more northern parts of the country, there still remains ample sunlight to make going solar worthwhile.

Solar system power generation estimates:

The average Tasmanian rooftop receives an annual average of about 4.4 hours of sun per day, although this number will be higher in the summer and lower in the winter. Estimated daily generation figures for different size systems based on 4.4 sun hours are detailed below.

1.5kW solar system – 5.6kWh 

2kW solar system – 7.5kWh

3kW solar system – 11.2kWh

5kW solar system – 18.7kWh

Power consumption vs solar generation in Hobart & Tasmania: How solar panels can save you money on your power bill

Choosing the right solar system size for a home or business requires first understanding the occupant’s/owner’s budget & goals, plus the government incentives available to them. Different homes use different amounts of electricity, and at different times of day. Tasmanian households & businesses should aim to consume as much of the solar electricity that their systems produce as possible to ensure they get the most value as possible. Excess electricity, which is automatically exported to the grid when not consumed by appliances inside the building it services, will earn their owners credits on their bill to the tune of about 8c/kWh, whereas consuming the solar power directly will save them 20c+/kWh on their power bills in the form of avoided electricity purchase.

Basically, it is a question of ‘offset value’ vs ‘export value’, and the offset value of solar power is much more than the export value. This means that solar system owners should try to consume power as much as possible during the daytime, and systems should be sized to meet daytime demand (unless you also install a battery storage system).

Tasmania Federal Government Solar Rebates for Hobart & Tasmania

Hobart residents who install a solar panel system will receive what is effectively an up-front discount from the federal government through the Renewable Energy Target scheme (RET). This discount, which comes in the form of  ‘small-scale technology certificates’ (STCs), applies to any certified renewable energy generation system under 100kW in capacity. In Hobart and the rest of Tasmania, STCs effectively cut about 55-65c per watt from the cost of having a system installed.

There is a mistake in the paragraph below. You probably mean … greater than you heating loads in the winter, instead of “greater than your cooling loads.”

Bear in mind, though that the assumption behind this formula is that your summertime cooling loads (refrigerator, AC, etc) are greater than your cooling loads. This is generally the case as most homes do not use electricity for heating (instead opting for gas, wood, or oil), but they do generally use electricity for cooling.

Thanks, Roger – we have fixed the typo. And your point that summer electrical cooling loads are usually lower than winter electrical heating loads in most homes is definitely correct. Each home should look at their own situation carefully before making a decision about going solar.

Could you please advise what tilt angle a solar array should be installed at when the house is situated very close to Hobart?

Many thanks,

John Holloway

Hi John,

As a rule of thumb, grid-connected systems should have their solar panel array tilted so as to optimise for summer solar irradiation. The formula for this is latitude minus 10degrees. Since the latitude for Hobart is 42, the best tilt angle would be around 32degrees. (Read more: Solar panel tilt & orientation in Australia.)

Bear in mind, though that the assumption behind this formula is that your summertime cooling loads (refrigerator, AC, etc) are greater than your heating loads in winter. This is generally the case as most homes do not use electricity for heating (instead opting for gas, wood, or oil), but they do generally use electricity for cooling.

Hope this helps!

• Tasmanians who have solar power and are producing more than they use are currently receiving a 1 for 1 feed-in arrangement for feed-in. This mean that they are essentially able to “park” their excess power at Aurora and the save that for a time of year when they need it.
• Treasury is analysing and reviewing the current system of solar grid feed-in rates in Tasmania and the talk and fear in the community that we may end up with a 6 or 8 cent feed-in tariff.
• Tasmanians who have installed solar power, have done so with the security of a one for one feed-in tariff. This made it a viable proposition for them.
• Without the feed-in tariff as we have it, the investment will be scuttled by any decision to reduce tariff to such a low level.
• The many solar businesses in Tasmania will be put at extreme risk of failing with a huge lost of job directly and indirectly in the industry.
• Local jobs and further expansion and employment opportunity is now under serious threat and the future is resting on the outcome of this government decision.
• We can combine our voices to demand that our feed-in tariff is retained is protected by legislation from our parliament.
