Your power bill can be heavily supplemented by installing a Grid Connect (or “on Grid”) Solar PV system on the roof of your home or business.
Solar Modules (‘PV Panels’) are usually mounted on the roof of your home or business. When sunlight hits the panels, DC power is produced. This power is then sent to a Solar Inverter which converts the DC electricity to AC power which can then be used by your appliances.
Any surplus electricity your system generates is automatically exported back into to the main electricity grid and can further supplement your electricity bill.
Systems begin at 1.5kW and will produce around 2100kW a year - that’s a quarter of the average household’s yearly energy.
Your power bill will give you an accurate indication of your yearly kW usage. Your PV provider will be happy to help you select the right system to suit your power requirements and budget.
Grid Connect PV Systems can heavily supplement your power bill and are customised to suit your power requirements and budget. PV Systems offer fantastic Return On Investment - meaning more money in your bank!
With residential electricity prices increasing an average of at least 5% per year over the last ten years - you can protect yourself from further predicted increases as you will only be paying for a portion of your power usage
The importance of sustainable living is increasing and energy efficiency is a popular selling point. A 2011 study carried out in the US found that a Grid Connect PV System increases the resale value of a home, and a home with a Grid Connect PV System is likely to sell twice as fast as a home without one.
PV Systems produce Environmentally friendly, emission free power
Quality brands offer long term warranties on their panels (usually 25 years) and guarantee power output. Inverter warranties range from 5 to 25 years.

While sunny days produce the best conditions for maximum output of a solar power system, you can still generate substantial amounts of energy on cloudy days. PV solar is actually more efficient in cooler climates.
An on-site inspection by your PV provider will enable your PV System to be carefully positioned - ensuring maximum efficiency and output of your system.
With no moving parts, there is virtually no maintenance required for your system other than cleaning (if required) or ensuring tree growth does not become and obstruction.
Most PV Panels carry an output warranty of 25 years and are guaranteed to produce 80% of the rated power output at this time.
Yes, systems can be dismantled and moved to a new property.
