Solar FAQs

PV stands for photovoltaic. This is the technology whereby solar cells are used to convert sunlight into electricity.

Photovoltaic cells are made up of semiconductor material such silicon. The silicon is mixed with elements phosphorous and boron which create conductivity within the cell and activate the movement of electrons. The electrons move across the cells when are activated by the sunlight’s energy into the electrical circuit hooked up to the solar panel. Therefore, the power produced by a PV array (group of solar panels) increases with the intensity of the light striking it.

Tier 1 panels are within the top 2% of Solar PV manufacturers. Tier 1 solar panels are the highest standard of panels available in the world. They only come from vertically integrated manufacturing companies, which means every stage of the manufacturing process is quality controlled. Tier 1 manufacturers invest heavily in research and development and use advanced robotic processes. To be a tier 1 manufacturer you must have been manufacturing solar panels for over 5 years. Tier 1 manufacturers use the best grade of silicon to produce solar cells. The higher the silicon grade, the longer the solar cell will last and the better it will perform. Bradford only use tier 1 manufactured solar energy products.

There are a few things which need to be considered:

You will need to match the installed components to current equipment (panel wattage and inverter capacity);
You will have to reapply to connect additional panels (kW’s) to the grid. This effects current feed in tariff arrangements (adjusting the system may remove your current FiT);
If the system is older it will need to be brought up to the current electrical standard – the requirement and costs will depend on the year of install.

Overall it is typically more cost effective to install an additional system if you wish to generate more power.

Yes. Shading can affect the output of the entire string to be reduced to virtually zero for as long as the shadow sits there. In severe cases, a shadow does not necessarily need to fall on an entire panel. Depending on type of system installed, shading on a single cell could reduce the output of the panel and in turn the entire string (a string is a series-connected set of solar panels).

In a conventional solar panel string, shade is something that blocks the flow of the electrical current. However if there is a separate unshaded string, the string will continue to produce power as per usual.

Importantly there is a solution to shading; Bradford Solar recommends SolarEdge DC Optimisers which are included in all our SolarEdge systems. This will increase the energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually achieving the optimal output.

Bradford will always provide you with expert solar advice, as we are members of the Clean Energy Council we must adhere to the code of conduct which stipulates we must assess whether a roof is suitable for mounting an PV array. Taking into consideration what roof space is available, orientation and tilt of the panels (this affects the daily performance of how much solar energy your system may generate) and any shading which will occur and how it will affect the system performance.

Power optimizers increase the energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually. Furthermore, the power optimisers monitor the performance of each module and communicate performance data to the monitoring portal for enhanced, cost-effective module-level maintenance. Each power optimizer is equipped with the unique SafeDC™ feature which automatically shuts down modules’ DC voltage whenever the inverter or grid power is shut down. The MPPT per module allows for flexible installation design with multiple orientations, tilts and module types in the same string.

In traditional Solar PV strings without optimisers, issues such as shading on a single panel would affect the entire string equally. For example, shading 50% of one panel would reduce the entire system efficiency by 50%. The DC optimisers allow each panel to work independently, so only the output of the afflicted panel will be affected. So if one panel goes down, or is not performing well, the rest of your panels can still be working at optimal output.All Bradford Solar packs that include SolarEdge systems include SolarEdge DC Optimisers on the rear of each solar panel.

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.

The best position to install PV panels is on a roof plane which is facing closest to true north. Facing closest to true north optimises the exposure of the solar panels to the path of the Australian sun, resulting in maximum power generation.

The tilt angle of the panels is also important and is dependent on the pitch (angle) of the roof. Most Australian homes have a moderate roof pitch (angle) and this is usually suitable to the panel tilt angle required. However, if you have a flat roof, or an unusual roof pitch, Bradford Energy can supply tilt frames that allow the panels to be adjusted to the optimum angle.

In the southern hemisphere, solar arrays (one or more solar strings) should face north to collect maximum sunlight during the day. The panel tilt should be set to the local latitude to optimise the sunlight across the seasons. A north facing panel tilted to match the latitude will almost always optimise the performance.

The inverter (a critical unit as it converts solar energy to electricity) is best installed near your existing meter box; either inside or outside is fine as long as the inverter is not exposed to direct sunlight for an extended time.

Solar generates the most power when it is sunny. Heat can actually reduce the performance of solar modules. However, even on an overcast day your system will still generate about a third of the power it would generate in direct sunlight.

With Bradford systems, CSR – an Australian icon for 160 years – provides the warranty. If you have problems, we are here for you. Cheaper inverters often come with a manufacturer’s warranty, and if you need to claim, you have to deal with an overseas company.

Like any appliance exposed to the environment there may be dirt built-up over time.

A good way to track whether your system may require maintenance is by installing a monitoring device. Monitoring devices can allow you to see real time data of how much solar energy your system is generating.

In the event your systems output decreases you can call our customer service team for advice and support.
