STCs, or small-scale technology certificates, are a form of government incentive in Australia that provide a financial benefit to Solar system owners for each megawatt-hour of electricity generated by their system. These certificates are created when a Solar system is installed and can be traded on the open market, providing a source of income for system owners.
Feed-in tariffs, on the other hand, are a payment made by electricity retailers to Solar system owners for the excess electricity generated by their system that is fed back into the grid. This payment is typically made at a higher rate than the retail price of electricity, providing a financial incentive for Solar system owners to generate more electricity than they consume.
Both STCs and feed-in tariffs can help reduce the payback period for Solar system installations and make Solar power a more attractive investment for homeowners and businesses. By leveraging these financial incentives, Solar system owners can not only reduce their electricity bills but also contribute to a more sustainable energy future.
