Renewable energy from the sun allows you
to lower your electricity bills
Once your home is reasonably thermal efficient you should consider
utilising the benefits from the sun to generate your own electricity.
We currently install over 200kW of solar per month in the residential sector, and have been selling / installing solar PV systems for years. Our internal renewable energy electricians are experts in string inverter and optimised systems, and enjoy access to a range of tier 1 and premium panels at competitive pricing.
We will guide you through the activation process – we have full-time Solar PV Administrators that manage the communications with TasNetworks, Aurora Energy and other bodies, as well as present warranty and support information to you.
The energy output depends on your system size. The larger the system, the more energy it generates. Additionally, the solar system’s energy output depends on your location in Australia, the direction your panels are facing (with north being the best), the tilt angle, and also the day and season.
Solar panels produce most power when they are pointed directly at the sun. In Australia, solar modules should face north for optimum electricity production. For grid-connected solar PV power systems, the solar panels should be positioned at the angle of latitude to maximise the amount of energy produced annually.
Most Australian homes have a roof pitch of 20° to 30°. If your roof’s slope is not ideal, our solar installers can create an appropriate mounting frame to correct the orientation and elevation of your panel.
The amount of sunlight that a solar panel receives over a day is expressed in peak sun hours. As the amount of energy generated by a panel is directly proportional to the amount of energy it receives from sunlight, it is important to install panels so they receive maximum sunlight. One of our solar energy specialists will calculate the amount of energy generated by the solar PV panel from the peak sun hours available. Peak sun hours vary throughout the year.
Yes, shading definitely affects the performance of your panels. Shade from trees, roof ventilators, or antennas changes the flow of electricity through the panel, thereby reducing the performance. To maximise their energy-storing capacity, PV panels must be in full sun from at least 9am to 3pm and must be kept free from shade, dust, and other impurities.
Fortunately, the Suntech and LG Solar photovoltaic modules used in Bradford’s solar energy system are created with a bypass diode that minimises the power drop caused by shade. In homes where there are shading issues or panels have to be installed in different directions or roof orientation, we suggest you explore the AC panel – micro-inverter range. Ask us if they are suitable for your requirements.
The amount of electricity a solar PV panel can generate is reduced as temperatures increase. Solar panels operate best at ambient temperatures up to 25°C. However, if the temperature is higher, the panel’s output declines.
No. The panels are tested to withstand hail. A hail test is conducted with a 20 mm diameter ice ball at 23 m/s (82km/h), directed at 11 impact locations.
Solar PV Energy System Pricing
HEG has a standard price list that applies to homes or businesses – please contact us on 1300 744 767 or firstname.lastname@example.org for an obligation-free quotation. Every solar installation is different, with the major variations occurring in these aspects:
- Roof type, roof area, orientation, pitch, quantity of roof facets and access considerations;
- Shading caused by trees, hills, nearby houses and other parts of the same house/roof; and
- Usage of power at different times during the day and in different quantities.
Each household or business has a different energy consumption profile (when / where / why energy is used over the course of a day, month and year), and often the reasons behind the need for solar PV or battery storage varies. Often it is to lower costs, but other times it is to ensure brown / blackouts are minimised.
HEG Energy staff will discuss these various options with you to enable you to make an informed decision. The cheapest option is not always the optimal option for your particular circumstances.
Great, reliable solar PV products.
The following components form part of the standard or premium-upgrade solar energy packages:
- Zever Solar Inverters or SolaX inverters
- SolarEdge Inverters & Power Optimisers (for shading situations and power output fluctuations)
- Canadian Solar panels, which are Tier 1 and range in specifications from 270W to 320W, 60-cell to 72-cell
Other Tier 1 panels (e,g. Risen,LG) and inverters (e.g. SMA, ABB, Fronius) are available – simply ask.
SolarEdge Inverters with Power Optimisers are available as an upgrade. Ask staff for details.
