What is solar quoting software?
It calculates the price and financial outcome of a solar system, rebates like STCs, finance, GST and the savings a customer sees based on their tariff, turning a design into an accurate, defensible quote.
Does Solar Proof calculate STCs automatically?
Yes, based on system size and location, and it handles GST and finance so your pricing is accurate without manual maths.
Can it read a customer's power bill?
Yes. Magic Power Bill reads a PDF bill and extracts the real tariffs, supply charges and time-of-use periods, so your quote uses their actual rates.
Does it handle time-of-use tariffs?
Yes, flat, block and time-of-use, plus interval (NEM12) import, so savings reflect how and when the customer uses power.
