Solar PV is a renewable energy system which uses photovoltaic modules, usually on the roof of a building, to convert daylight into electricity. Photovoltaic cells are made up of thin layers of semi-conducting material (usually crystalline silicon) which generate an electrical charge when exposed to direct or diffuse daylight.
STC’s are Small Scale Technology Certificates and are used as a form of currency they are generated by the installation of green energy systems, the larger the system the more STC’s are created, you may keep them, sell them or sign them over to Halcol Energy to reduce the cost of your solar energy system.
Sunlight hits the photovoltaic cells and is converted to clean electricity. The inverter converts the electricity from direct to alternating current, so that it may be combined with the electricity being imported from the mains, and used to power appliances in your home. When the solar energy system produces more power than is needed, it is exported into the electricity grid. At night, power is imported from the electricity grid in the usual manner.
Once installed and commissioned, you own the system, having control of a long-term free source of electricity that is exempt from price increases. You are not only saving money but actively saving the environment at the time. A Solar PV system makes no noise, has no moving parts, requires minimal maintenance, has a long lifespan and generates no CO2 emissions. Basically, it produces clean energy for years to come.
The location of your PV array (group of PV modules) is vitally important. The modules should receive the maximum amount of daylight possible, so it is not advisable to install the modules in situations where surrounding buildings or trees may cast shadows. The best location for a PV array in is on a north-facing roof angled at 30 degrees although east and west facing usually provides a minimum of 90% efficiency . Halcol Energy has various mounting solutions including on-roof, in-roof and flat-roof options, both landscape and portrait.
If the optimum angle is not achievable, over 90% of the maximum annual energy can still be achieved at 10 degree and 50 degree tilts and east and west facing roofs. North-facing vertical facades generate around 70% of the maximum.
Shading is critical. Minor shading can result in significant loss of energy. Since PV modules are linked together in series, the module with the lowest amount of irradiation falling upon it determines the operating voltage of the string in which it is connected. This is one of the factors considered in the Halcol Energy site survey carried out before any installation.
Yes. The PV modules only require daylight to work, and so will generate energy on dull and even rainy days. Temperature is also a factor when determining how much electricity a PV system will generate. The efficiency of a PV module decreases by a fraction for every degree the temperature is above 25 degrees Celsius. Therefore, a clear chilly day is perfect, because PV modules operate better at cooler temperatures.
A Solar PV system is silent in operation, has no moving parts and requires minimal maintenance. Most of the time the rain will keep the modules clean. However, a build up of dirt can effect system performance. The degree of soiling will depend on the location but usually dust accumulation and self-cleaning reach a steady state after a few weeks if the array tilt is at least 15 degrees. In extreme cases, dust may cause a power reduction of about 10%. The design of the system should aim to minimize uneven soiling. The modules can be cleaned once a year if desired with either a hose or, if possible, soapy water and a non-abrasive cloth.
There is no simple answer to this question. It will depend on how much you want to invest, how much of your electricity you want to generate via PV, and how much un-shaded roof space you have. It is not essential to provide ALL of your home’s electricity via solar PV (since you will still be connected to the national grid). If your PV system supplies half of your electricity, it will still make a serious reduction to your carbon footprint! After talking through your exact needs, Halcol Energy will be able to recommend the size of system you require.
According to statistics, the average three-bedroom house consumes 6497 units of electricity (kWh) a year. However, Halcol Energy always recommends that you look at your last few bills or call your electricity supplier to find out how many units you consume. You can then compare this to the output of the system which Halcol Energy recommends
Whenever your panels are producing more electricity than your home is using, it will flow back into the grid for other homes to use. After you have a solar system fitted the energy company will be notified by us to install a bidirectional meter that measures the amount of electricity imported and exported, you are eligible to receive a credit for the electricity exported. This will lower your electricity bills and ensure none of your green electricity will be wasted. Some energy companies are offering up to 11c kWh for energy you export to the grid!!
No. Halcol Energy’s Solar Systems are connected to the national grid. In the night, when the cells are not generating energy, electricity is bought from the utility company in the normal way. Any excess electricity generated during the day – for example, when you are at work – is sold back to the utility company.
Halcol Energy’s Solar Systems for homes are entirely grid connected. If there is a power cut, your system is automatically switched off. This is a safety measure designed to stop electricity leaking on to the national grid and to protect individuals who may be working to restore the power supply.
The cost of installation is dependent on a Halcol Energy detailed survey and will vary according to how easy or difficult it is to access the roof space and the type and size of the PV system chosen. Please contact us for current pricing. A Solar PV installation adds as little as 4% to the build cost of an average new three-bedroom home, but this can be added to its final value when sold. It also helps ‘future proof’ a home against rising fuel prices making properties doubly attractive to price-conscious house buyers. As fuel prices continue to rise, energy-efficient renewably powered homes will continue to sell at a premium.
Government grants have stopped but they offer another incentive in the form of STC’s (Small Scale Technology Certificate) these are available to help cover the cost of a PV installation for domestic systems.
PV systems can be installed and ready to produce electricity in 2-8 weeks from the time the design has been agreed depending on availability. The actual installation will take approximately one day depending upon your building type.
No. Currently, Halcol Energy only services the QLD district of Australia, though there are plans to expand coverage. Our licenced electrical contractors are fully trained to install photovoltaic systems throughout Australia, hence we are keen to expand our servicable area.
No. Solar PV modules constructed with a glass front have two characteristics that reduce light reflection. In order to optimize electrical yield, the glass is treated with an anti-reflective coating which greatly increases the transmittance through the glass, maximising the amount of light reaching the solar cells. Secondly, the outer face of the glass has a slight granular texture. The result is a matt-like finish – rather than mirrored. Again, this is actually intended to maximize yield. These two characteristics greatly reduce reflection from the glazed front face of solar PV modules when compared with conventional glazing.
Solar energy technologies often have a higher investment cost. This means that a person is likely to pay more money initially to purchase and install a solar PV system. Still, in nearly all cases, the high initial cost is recovered through substantial fuel savings within the life of the product (40+ years). This time is significantly reduced by any government incentives in place such as grants and Feed-in Tariffs.
All Halcol Energy pv modules come with a 25-year performance warranty so, in the unlikely event that you experience problems, Halcol Energy will be on hand to diagnose your problem and, if necessary; arrange a home visit to ensure that everything is working as it should be. The installation comes with a 5 year warranty so you can be sure your service will be of the highest standard.
PV systems can be blended into virtually every conceivable structure for commercial buildings. You will find PV being used outdoors for security lighting as well as in structures that serve as covers for car parks and bus shelters, generating power at the same time. PV systems are also used to offset and operate all kinds of electrical systems, including lights, cooling systems, and appliances.
Today’s modules can be built into glass skylights and walls. Some resemble traditional roof shingles. Architects can use building-integrated PV (BIPV) to design buildings that are environmentally-responsive, aesthetically-pleasing, and produce their own power. BIPV provides a dual-use building material, reduces PV system costs by using the building as the mounting or support structure, and reduces utility bills through on-site power production.
After looking at a number of Solar Energy Company's to purchase Solar Panels, we went with Halco Energy on the Sunshine Coast.
- Had a problem with installation, wrongly wired
- Having fault issues with Sungrow Inverter
- Customer service not the greatest
Just letting you know!!!
What fantastic value and service...have used Halco Energy several times now to purchase solar panels. Each time they have been prompt and helpful to fulfill my house & families requirements. Found the staff extremely easy to deal with. Thanks Andy, Sam and Alex appreciate everything you have done.
We have just had installed our second Halcol Solar System to our second house we have just purchased and are very happy with it. The crew that installed it were very professional and friendly. The staff at Halcol were very help full and Tony (our Rep) was very easy to work with. He was very patient with me. The system that we fitted has wifi capability. It can be monitored with your mobile phone, tablet or computer. Halcol can also monitor your progress. I would highly recommend Halcol if you are in the market for a solar system. We checked out the opposition with all there cheaper deals but found the quality of the Halcol product and service rose above all the others. Pete Jones Minyama
I've known Halcol Energy for close on 6 years and have always found them to be professional.
Stability in business has proved to be difficult so it's comforting to know that Halcol has grown and is still growing.
I would recommend them to anyone who wants to install a quality system backed by a quality business.
Doug from Buderim.
Highly recommend using Halcol Energy, they were professional and so efficient. From the first telephone call to the finished installation, we had no problems and would definitely tell everyone to use them. And a local company too.
Have only had our 5kw/18 panel system up for less than a week so can't comment other than to say it's certainly working well and pumping out the energy. Still waiting for Energex to do their bit so we can start getting the credits but to be honest our main concern is using the power ourselves. Have found Halcol very friendly and efficient to deal with from the salesman, Tony, through to Tim & Alex who did the install. Happy to recommend them.
Halcol have been most accommodating as the solar was being put into a currently rented house that was also have the roof repainted. They fitted in with the painters and tenants. Really appreciated. The price was very competitive and the staff always pleasant.
I had a 5kw system installed by Halcol over 18months ago. I was really impressed by the salesman who was informative and answered all my many questions. Installation was prompt and efficient. Click Energy was recommended for power provider I thought I'd wait and see if all was as good as expected
My solar power has been even better than promised. I have not had a power bill since installation. I use the aircon daily in summer and heating nightly in winter.
I took me a few years to decide to get solar. I wanted to see who were the 'stayers' after the first rush! I'd recommend people do it NOW. Crazy not to. An under $5k outlay for no more power bills is well worth it
Initial purchase and installation tops, however we required panels removed and replaced to facilitate roof repairs and repainting two years later. Not good, won't go into details here, suffice to say disorganised, non-competitive in price and lacking adequate on-site safety and customer considerations. Had to complain and then still experienced what seemed to be a lack of coordination in service activities. Hoping no one else has to go through similar.
Halcol have installed new lights and a large and efficient solar power system. Throughout, all team members have been polite, punctual and professional. I recommend them wholeheartedly for any electrical work.
The guys who installed our system did a great job .we had a difficult installation but nothing was to much trouble . Very neat job as well wouldn't go to anyone else! Happy to discuss our installation 10/10
Our daughter referred us to Halco. Tony looked after us & we found him to be very knowledgeable and honest about what we should expect. We were very impressed with the whole experience from beginning to end. Thank you again
Extremely professional company to deal with from the Sales rep to the installers to the lovely Lisa in the office. We checked their reviews, then did a comparison with 2 other quotes and chose Halcol as it was the best fit and the best quote for us. Install booked for 7.30 they arrived at 7.29 and were done by 1pm. Quick and efficient without any broken tiles which all 3 companies had advised can happen. They then explained the inverter in full detail and we couldn't be happier with the whole experience.

I was always very enthusiastic about this mob (local business; I support that), but my experience with a warranty replacement and the telephone manners of one of Halcol's staff has left a bad taste in my mouth...... I don't wish to be spoken to like I am stupid. Five stars initially; down to three. Hopefully back to five if this issue gets sorted.
We have just had airconditioning installed by Halcol and are very happy with the service, the products installed and the efficiency of the workers. They were prompt, well mannered and explained the process clearly. It was a difficult job, owing to the design of the house and the extreme heat on the day but they did not complain and were very courteous. We also previously had solar panels installed by Halcol and have been very happy with them.
We recently had Solar installed at our home. The staff were extremely informative and gave us several options to choose from especially to suit our individual living needs with competitive prices to.
Reliable, efficient and professional at all times. Even a few weeks after installation we had a few questions as it was our first time having Solar & the staff were quick to respond & very helpful without any hesitation.
I would highly recommend and we will most certainly use the Halcol team for our future properties. Also if you have any enquiries about Tesla - Halcol are very much up to date on the product. Thanks Again Andrew
DO NOT Buy from these guys their products (mass inverter) has been delisted which means they are not safe and not effiecent. They don't tell you this and one of my family members that regrets buying a system Had to find out online.
