Using a renewable energy source to power your home is an important factor in assessing a property’s energy efficiency.
Along with other factors such as construction materials, the building’s orientation, and its design relative to the climate it is situated in, installing a renewable energy source has a significant, positive impact on your overall home energy rating.
Heating and cooling are responsible for most of the average Australian household’s energy use and greenhouse gas emissions. Grid electricity generated using fossil fuels results in high carbon emissions (which contributes to global warming) in contrast to solar energy technology, which produces none.
If your home generates energy for household use through rooftop solar PV panels, it will naturally benefit your property’s energy rating. If you have a battery energy storage system (BESS) for capturing and storing your solar energy – even better!
Solar PV panels only generate electricity during daylight hours, so houses with a BESS have the added advantage of consuming even less energy from the grid, as they can make use of stored solar energy at night. But apart from minimising your purchase of costly grid energy, a solar energy storage system can also increase the resale value of your house by boosting its home energy rating.
As Australia moves towards its goal for new homes to have efficient thermal shells, renewable energy sources, and energy-efficient appliances, demand for properties with a higher energy rating will naturally increase in line with buyers’ expectations.
For those interested in achieving a good home energy rating, whether for an existing or planned home, installing a solar energy storage system is a huge step in the right direction.
