PV Master turns confusing solar numbers into clear decisions, so you spend less on power and waste less of the sun. Using just your location, PV Master shows you what your roof can really do, when to rely on your own panels, and when to lean on the grid. Whether you are planning your first system or fine tuning an existing one, you get answers you can act on. What PV Master helps you do: Plan with real numbers, not guesses. Get accurate, location based solar data plus a live grid forecast, so you know the best times to use your own power and when cheaper grid power makes sense. Position your panels for maximum output.
