Solar works in Hobart, even with the cool climate. Clear, crisp days and long summer evenings make up for shorter winter days, and many households now pair panels with a battery to cover evening heat pump use. Steep roofs, shading from hillsides and trees, and older roofing in suburbs like Lenah Valley and Taroona make good system design more important than in flatter cities.

Solar installation in Hobart is handled by a mix of Tasmanian owned specialists, electrical contractors who added solar, and multi trade firms. The best choice depends on whether you want panels only, a battery, an EV charger or a full home electrification package.

Solar work must be done by licensed electricians, who in Tasmania are licensed through CBOS (Consumer, Building and Occupational Services). For rebates, installers also need Solar Accreditation Australia (SAA) accreditation, which replaced the older Clean Energy Council installer scheme. Ask about both, and whether the installer is a New Energy Tech Approved Seller.

Residential services cover solar systems, home batteries, heat pump hot water, EV charging and off grid systems, with commercial solar, battery and hot water work for businesses. It also offers maintenance and upgrades for existing systems, which is handy if your older inverter has failed.

Solahart Southern Tasmania is the local dealer for the Solahart brand, based at 159 Main Road, Moonah, opposite the Moonah Bowl. It is open weekdays from 8am to 5pm. The dealer says it has served local customers since 2005 and has installed more than 1,700 systems.

It designs and installs solar hot water, solar power and battery storage for homes and businesses, starting with an assessment of your energy needs. Its service area runs across Greater Hobart, the Huon Valley and up the east coast as far as Swansea, which suits shack owners and rural households that some city installers will not travel to. Solahart is best known for solar hot water, so this dealer is a natural choice if you want to replace an electric cylinder and add panels at the same time. Ask for itemised quotes on each part so you can compare against independent installers.

3. Degree C — Cambridge Office Of A Statewide Multi Trade Contractor With Solar And Batteries

Degree C is a Tasmanian multi trade contractor with its head office in East Ulverstone and a Hobart office at 2 Stanton Place, Cambridge. The company says it has operated for more than 60 years and covers solar, heating and cooling, refrigeration, electrical, fire and safety, and security across the state.

Its solar team designs and installs grid connected solar and hybrid or AC coupled batteries for homes and businesses, along with solar switchboards, metering, energy management systems and EV charging. Southern service areas include Hobart, Sorell, Richmond, New Norfolk, Kingston and Huonville. Degree C displays SAA Qualified Installer, New Energy Tech Approved Seller and NECA member logos, offers a five year workmanship warranty, and says most jobs take about four to six weeks from quote acceptance to grid connection.

4. Castle Solar — Hobart Solar And Electrical Team With A 15 Year Workmanship Guarantee

Castle Solar is a Hobart solar and electrical business that serves the wider state. Its whole team is in house, and the company says it uses no subcontractors, which means the people who design your system are the same people who install it.

Services include grid connected solar, home batteries, servicing, solar panel cleaning and maintenance, EV chargers for single and three phase properties, split and ducted heat pumps, and residential electrical work such as rewires, switchboard upgrades, lighting and security. The standout is its 15 year workmanship guarantee, which is longer than the five or ten years many installers offer. Castle Solar suits homeowners who want one business to handle solar, a battery and any switchboard work needed beforehand, and who value a long guarantee on the installation itself rather than only the manufacturer warranties on panels and inverters.

5. TAS Solar — Hobart Installer With More Than 3000 Systems And No Outsourced Installs

TAS Solar is a 100% Tasmanian owned and operated business that grew out of an electrical contracting firm established in 2004. It moved into solar more than a decade ago and says it has completed over 3000 solar system installations.

The company offers licensed and accredited design and installation, site visits to work out the best panel placement, and ongoing customer care. It states that installation is never outsourced. Because it is also a licensed electrical contractor, TAS Solar handles residential and commercial electrical work such as heat pumps, lighting, electrical safety and new home wiring. The site lists Clean Energy Council installer accreditation and New Energy Tech accreditation, so ask how this has carried over to SAA. TAS Solar suits households that want a long running local installer for a straightforward grid connect system, with electrical work done by the same team.

6. Expert Energy Tasmania — New Norfolk Solar Team Specialising In Off Grid And Battery Systems

Expert Energy Tasmania is based at 8/26 The Avenue, New Norfolk, just up the river from Hobart. It is led by founder and director Scott Logie, with an operations manager, a technical representative and an electrical contracting manager and co-director named on its site.

The business designs and installs solar for homes, businesses and organisations, along with battery storage, EV chargers, energy meters, heat pump split systems and heat pump hot water. It has a particular focus on off grid systems, recommending lithium batteries and backup generators, which suits rural blocks in the Derwent Valley, Huon and highlands where grid connection is costly or unreliable. Expert Energy says its exclusive Tasmanian partnerships give access to strong product warranties, and it describes typical financial returns within three to six years. It suits rural landholders and shack owners who need a properly sized off grid or hybrid system.

It describes itself as a husband and wife business, with Edward Guglielmino as chief solar systems designer. The company says it is a New Energy Tech Approved Seller and follows the New Energy Tech Consumer Code.

It installs solar panels, battery storage and EV chargers, along with heat pump hot water and home security systems. Its main point of difference is whole home automation, where an energy system manages the battery, car charging, hot water and heating together. SolarGenTas is also an official partner of LocalVolts, a retailer that offers spot price electricity plans, which can suit households with batteries that can shift use to cheap periods. The company reports a 5.0 Google rating from 29 reviews. It suits tech minded households on the eastern shore who want to automate their energy use, not just add panels.

How To Choose A Solar Installer In Hobart

Is The Installer Licensed And SAA Accredited?

Solar and battery wiring must be done by an electrician licensed through CBOS, and installers need Solar Accreditation Australia (SAA) accreditation for systems to qualify for small scale technology certificates, the main federal rebate. Derwent Electrical publishes its licence number, and several installers here display SAA logos. Ask for both before you sign.

Will Your Own Staff Do The Installation?

Some solar businesses sell systems and subcontract the installation. I Want Energy, Castle Solar and TAS Solar all state that their installers are in house. Ask who will be on your roof and who you call if something goes wrong.

What Warranties Apply?

There are usually three: panel product and performance warranties, the inverter warranty and the installer’s workmanship warranty. Workmanship terms vary widely, from five years at Degree C to 15 years at Castle Solar. Get all three in writing with the quote.

Do You Need A Battery Or Switchboard Upgrade?

A battery makes the most sense if you use a lot of power in the evening, for example running heat pumps on winter nights. Many older Hobart homes also need a switchboard upgrade before a system can be connected. Ask for both to be priced separately so you can see where the cost sits.

How Is Solar Priced In Hobart?

Most installers quote per system after a site visit or roof review, with the price depending on system size, panel and inverter brands, roof type and any battery. Few publish prices, so compare at least three itemised quotes. Ask about finance options such as green loans and any Tasmanian energy saver schemes.

Conclusion

Hobart has a good choice of local solar installers. I Want Energy and Solahart offer showrooms and high install counts, TAS Solar and Castle Solar keep installations in house, and Degree C suits larger commercial or multi trade jobs. For off grid and rural properties, Expert Energy and Derwent Electrical stand out, while SolarGenTas suits households that want full home automation.

Check the CBOS licence and SAA accreditation, ask who will do the installation and compare workmanship warranties as closely as you compare price.
