# Further information
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.
SunSPoT is an online platform that can be used to calculate the solar power potential of any rooftop – home, business, factory or school
