SolarCT is a powerful solar calculator designed to assist and guide users in overcoming the challenges of building solar systems, particularly for those new to green energy. The app aims to simplify the process and save users time and effort by facilitating calculations and providing step-by-step guidance when one is starting to build a solar system for their home.

The app caters to both green energy engineers and homeowners. It offers features such as calculating the right angle and direction of solar panels in various fields. It also guides the correct usage of wire and solar panel usage. The platform serves as an efficient app calculator. It determines the requirements of solar system components, as well as the number of solar panels and batteries needed. It also grants the appropriate size of the inverter/UPS and controller charger, as well the entry when it comes to connecting solar panels and batteries in series and parallel based on the system/inverter voltage.

The app's functionalities include advanced and step-by-step calculation options, which should provide accurate results for users. It also offers information on solar radiation and cumulative production of panels. This grant users access into the tracking of daily, monthly, and annual solar radiation. Users can simulate battery running hours; with this, they can comprehend how long batteries can power their appliances. It even includes guidance on the remaining battery capacity. Some more features include:  a calculation of the orientation and tilt of solar panels, a reminder set-up for panel adjustments, appliance consumption, a calculation of wire gauges and voltage drop, and a computation of water pump power.

SolarCT strives to be accessible to a wider audience by offering translations in English, French, Spanish, and Portuguese languages. Users are encouraged to provide feedback and report any issues they encounter.
