Explore your solar potential before you plan your installation. DARSA Solar & Charge helps you estimate photovoltaic production, compare roof orientations and prepare an informed inquiry for your home, business or solar park. START WITH YOUR LOCATION Search for a place, choose a point on the map or use optional device location. Explore solar irradiation and photovoltaic potential using JRC PVGIS data from the European Commission, within the available geographic coverage. CONFIGURE YOUR SOLAR SYSTEM Enter installed capacity and adjust panel tilt. Select one or several roof orientations, with shared or individual tilt and capacity values. Choose an on-grid, off-grid or hybrid system and record nominal battery capacity for your inquiry. UNDERSTAND YOUR ESTIMATE View estimated annual and monthly production and compare your configuration with an optimal position. Equivalent sun hours provide an energy-equivalent daily average derived from PVGIS irradiation; they are not a count of sunny days or a weather forecast. SAVE AND PREPARE AN INQUIRY Keep calculations and drafts locally. Add your contact details, roof photos and electricity-bill images, review the inquiry and send it through the native mail composer. Nothing is sent automatically. Sending attachments requires a configured iOS Mail account. MADE FOR YOUR DEVICE A visual home screen for homes, businesses and solar parks, interactive roof-tilt controls, native Apple maps and an adaptive interface for iPhone, iPhone Duo and iPad. Available in English, Serbian, German, French and Italian. Free to use. No account, subscription, advertising or tracking SDK is required. IMPORTANT Results are multi-year estimates, not guaranteed production or a detailed engineering design. System losses of 14% are an assumption. Local shading, equipment condition, battery operation and autonomy are not modelled. Nominal battery capacity is an inquiry specification. New calculations, maps and search require internet access and supported data coverage.
