Solar Electric Systems
While the technology behind solar energy may seem complex, when broken down, how solar power works is easy to understand – particularly in a grid connect scenario as it only requires a few components installed in your home or business. Whenever the sun shines (and even in overcast weather), the solar cells generate electricity. The grid connect inverter converts the DC electricity produced by the solar panels into 240V AC electricity, which can then be used by the property/household.
Grid connected solar electricity makes it possible for you to turn your roof into a 100% renewable energy generator. Power produced by the system is delivered to your house first and any excess power is fed back to the grid. By avoiding the use of electricity created from fossil fuels, you'll contribute to the health of the planet. If a grid connect system is producing more power than is being consumed, the surplus is fed into the mains power grid. Some electricity companies will meter the electricity fed into the grid by your system and provide a credit on your bill. When the solar cells are not producing power, for example at night, your power is supplied by the mains power grid as usual. The energy retailer charges the usual rate for the power used.
Value for your home
Your grid connect solar power system will provide value to your home by quietly and reliably producing electricity every day of its long life. Beyond simply avoiding purchase of coal fired power from the utility, the system adds financial value to your home. A PV system is a capital improvement to the building and will increase its resale value.
A 2 kilo-Watt (kW) grid connected solar power system installed in Sydney will prevent the emission of approximately 2.8 tonnes of Carbon Dioxide (CO2) Gas, the main gas responsible for global warming.
This is equivalent to removing a car travelling around 10,000 km per year from our roads.
