PV stands for photovoltaic. This is the technology whereby solar cells are used to convert sunlight into electricity.
There are a few things which need to be considered:
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.
The Bradford Solar ChargePack includes SolarEdge DC optimiser technology.
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.

This means that in case the manufacturer of the product is not available or in exisitence during the promised warranty period CSR Bradford will make good the same or equivalent product specifications. Peace of mind warranty from an over 160 year old ASX listed 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.
LG Chem RESU is a state of the art LG battery system for residential and light commercial applications that enables the storage of energy such as solar power. Commonly, LG can be used to store solar energy during the day for use at night time. It can also provide backup power in case of a grid outage. Depending on where you live and the electricity rates in your area, LG Chem RESU can potentially save you money by shifting energy consumption from high to low rate periods. Lastly, it can also help you take control of your energy and achieve self sufficiency from the grid.
Powerwall is a state of the art Tesla battery system for residential and light commercial applications that enables the storage of energy such as solar power. Commonly, Powerwall can be used to store solar energy during the day for use at night time. It can also provide backup power in case of a grid outage. Depending on where you live and the electricity rates in your area, Powerwall can potentially save you money by shifting energy consumption from high to low rate periods.
