Solar and storage systems are a big investment — but also a big opportunity.
The MTSC helps you make smarter decisions by clearly showing how much you’ll save each month and year on your current energy tariffs.
Whether you’re comparing different system sizes, storage capacities, or tariff structures, the MTSC gives you a clear financial picture in minutes.
Simply enter your site’s tariff data and monthly electricity usage.
The calculator simulates how solar and storage reduce your grid usage across peak, standard, and off-peak periods — giving you an instant snapshot of expected savings.
You can simulate:
As you adjust values, the MTSC automatically recommends optimal system sizes to reach your desired savings.
Once your data is entered, the MTSC instantly generates:
Perfect for proposals, quotes, or client presentations.
Just your tariff and usage data, plus your proposed PV and/or storage sizes.
The more complete your data, the more precise your savings forecast.
The MTSC is completely free for:

For a battery-only system, the calculator models how stored energy is used to reduce costs. Batteries charge during off-peak periods when electricity is cheapest and discharge during peak periods to offset high-tariff consumption.
In a solar-only configuration, the PV panels generate energy during the day to supplement and offset your standard-tariff usage. This reduces the amount of electricity you draw from the grid during daytime periods but does not include battery storage.
In a standard solar-plus-battery setup:
Batteries charge during off-peak hours.
Batteries discharge during peak hours to reduce costly grid usage.
PV panels are used primarily to offset consumption during standard-tariff periods.
When additional solar panels or larger battery storage are selected, the calculator optimizes both:
Extra solar generation can charge the batteries, reducing or replacing off-peak grid charging.
Batteries can discharge during both peak and off-peak periods, depending on available storage and solar input.
Excess solar can offset standard-tariff consumption or top up the batteries during off-peak hours.
