STCs
STCs are automatically calculated for quotes <100kW in Australia. The STC zone is determined by the site postcode, and the STC default value can be set in your Business Settings, and adjusted for individual quotes in the ‘Tax & Rebates’ tab.
Updating default STC price and related options
You can update your default STC price in Admin > My Business > Quote Preferences > Incentives
Quoting on jobs that will be installed in the following year
You can change the deeming years to adjust the number of STC certificates issued if the installation is planned for the next year. Towards the end of the year, when you begin quoting for jobs that won’t be installed until the following year, you can reduce the STC deeming years automatically by selecting this option in your Business Settings. This will automatically be cancelled on Jan 1.
Adjusting the STC value of individual quotes
You can adjust the STC deeming years and value for an individual quote by going to Pricing > Tax and Rebates
Set custom kW value for STCs
By default, the PV kW value used for calculating the number of RECs is based on the kW total of the new panels in the system design. However, you do have the option to check this box if you want to override the solar PV kW size on the design page to set a fixed value for calculation of the number of STC certificates.
GST on STCs for Commercial quotes
For Commercial quotes (sold to customers who are registered for GST), the GST on STCs is normally listed as a point-of-sale discount on the quote, but it’s not part of the GST for that quote - it’s subject to a separate invoice. There is an option in Admin > My Business > Quote Preferences > Incentives, to “Apply GST on credit for commercial quotes from Australia by default”, and you can turn it off if you wish.
Hot water heat pump STCs
You can create a Custom inventory item for STCs on heat pumps. Set the Category as Subsidy, and this will give you control over how the GST is applied. Set the price at the value of 1 x STC, and then when creating a quote, adjust the quantity from the edit quote tab of the Pricing page.

LGCs
Systems above 100kW may be eligible for Large-scale Generation Certificates, which are paid after the year in which generation was produced. They are not a point of sale discount. To apply to a quote:
Make sure you have selected the quote type as “Commercial” on the contact page. This is necessary for the LGC info to populate in the proposal.
From the Pricing page, go to the Tax and Rebates tab
De-select ‘Eligible for STCs’ and select ‘Eligible for LGCs’
The LGC Regression Rate is the rate at which you expect the LGC price to decrease annually. Enter your chosen LGC Regression Rate as a percentage.
Enter the LGC (REC) Value in dollars.
Save
This information informs the cash-flow table in the commercial proposal.
The forecast financial return from LGCs is based on: estimated solar MWh/year (derated for module degradation) multiplied by the LGC certificate price and the price regression rate, and sales tax applied.
So, the LGC value for year X = (LGC price per certificate) * (energy produced in year X) * ((1 - regression rate)^(X-1))
STCs and LGCs combined
While STCs only apply on systems <100kW, it is common to combine a 99kW system with another system and present them in the same proposal so that the client can take into consideration both the STC point of sale discount on the first 99kW, and the LGC income on the additional system. This is done in SolarPlus on the Pricing > Tax and Rebates page as follows:
The STCs will be shown on the quote as a point of sale discount
The LGCs will be shown as income on the cash flow table.
Both are taken into consideration when calculating the return on investment.
Remove the STCs line on quotes that don’t have solar
For quotes that don’t include solar panels, you can remove the line on the quote that relates to STCs/LGCs. Go to Pricing > Tax and Rebates and de-select ‘Eligible for STCs’
