Designing a Greener Tomorrow: UPH Electrical Engineering Professor Launches Free Web Tools to Simplify Solar Power Design
Designing an independent solar power system just became a lot easier, thanks to an innovation by Professor Henri Uranus from the Electrical Engineering Department, Universitas Pelita Harapan (UPH). He has developed a pair of user-friendly, web-based calculators designed to take the guesswork out of building off-grid solar systems. Whether someone is setting up low-power DC devices like smart sensors and LED lights, or larger AC appliances like household equipment and water pumps that require a power inverter, these tools help anyone figure out exactly what equipment they need.
The calculators work by turning complex engineering formulas into a straightforward process. Users simply plug in basic details, such as local sunlight availability (solar irradiation), how much electricity their appliances use, battery specifications, and desired operating hours. In seconds, the system accurately estimates the required solar panel capacity, battery storage size, charge controller, and even the necessary safety fuses. By making these calculations fast, reliable, and accessible to non-experts, the tools remove a major technical barrier for individuals and communities looking to switch to clean energy. To ensure these resources can benefit as many eco-conscious builders, students, and researchers as possible, Professor Henri Uranus has made both tools freely available online.
