Thinking about going solar, or trying to get more out of the panels you already have? 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. The built in compass and tilt tool helps you find the angle that captures the most sun all year long. Size your system with confidence. Simple calculators work out how much energy you need, how many panels and batteries it takes, and what it will cost, so you can weigh the ROI before you spend a cent. Get more from every sunny day. Local weather is built in, so you can see how conditions affect production and plan around them. Learn as you go. Clear guides, FAQs, and a plain language glossary explain every solar and photovoltaic term, so nothing holds you back.
