What is Sunulator?
Sunulator is a simulation tool that can help you plan for grid-connected solar power. Unlike most other solar calculators, Sunulator uses half-hourly consumption and generation data over a whole year to estimate how much solar generation will be consumed onsite versus exported. Based on electricity tariff information, it then calculates the impact on your electricity bill and projects the savings over a 30-year time frame. Financial results include payback period, net present value and return on investment.
We’ve used special customised versions of Sunulator in many projects for Government, energy companies and case studies. And it has been used widely in the energy industry, including by solar installers and regulatory bodies.
Sunulator allows you to compare the results for several scenarios, e.g different sizes of solar array or panel orientations, or different amounts of battery storage.
Community investment options
In Australia most solar systems are owned directly by the electricity consumer, usually a homeowner. Sunulator can also assist community organisations to install solar systems via additional investment options:
- A community organisation installs a system and sells electricity to the host site
- A solar system is installed through a loan from a community organisation
- A community organisation acts as an electricity retailer.
- Economic returns are estimated both for investors and the host site.
