The incentives for how solar power is produced and consumed may have changed dramatically since the Solar Feed-in Tariff [FiT] component was reduced in 2011, but small-scale technology certificates [STCs] in Western Australia are still proving to be very beneficial. A large percentage of Western Australia has access to lots of STCs.
Previously, customers were best off using as many appliances as possible outside of daylight hours so that they could export as much energy as possible. Now, the incentive is to use all major appliances during daylight hours so that you’re offsetting this usage with your own solar power. Now, most solar customers in Western Australia install systems which will offset only what they use during the day, taking into account any anticipated changes over the coming years such as a growing family or retirement.
With solar panel prices continually reducing in price each year, while the STCs remain quite high reducing, are two key benefits for Western Australian residents to invest in a domestic or commercial solar system.
The ever increasing cost of electricity means that solar is still a great investment and its benefits will only increase as years go by.
If you have any questions about how to use the formulas or any other matter, please don’t hesitate to ask us a question.
With the intention of encouraging more Australian homeowners, community groups and small business owners to invest in solar systems, the Government created the Small-scale Renewable Energy Scheme to help offset the upfront cost of the solar system. Under the scheme, any eligible, small [under 100kW] systems are entitled to a number of small-scale technology certificates [STCs]. These are also referred to as renewable energy certificates [RECs].
The total eligibility for an STC is determined by a combination of the system’s date of installation, geographical location plus the amount of electricity generated in megawatt hours [MWh].
A rough guideline for determining the amount of STCs that you might be eligible for is based on the assumption that one MWh is equal to one STC.
Postcode zones are one of the measures used to calculate the total quantity of STCs that a solar system may be eligible for, once it is installed. Each zone [below] represents the level of solar radiation for a geographical area.
To find the zone value for a solar panel system, crosscheck the postcode of the address where the system is, or will be, installed with the postcode range provided here.
