What affects the energy output of my solar system?

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.

What are the optimum conditions for a solar system to operate?

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.

How much sunlight should the panels receive?

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.

Does shading affect the performance of the panels?

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.

Does the temperature affect output?

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.

Is hail likely to damage my panels?

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.
