PV Master vs Solar Calibrator

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. It all lives in one friendly app, from first idea to finished install, with information that is genuinely easy to read. Download PV Master today and start making smarter, greener energy decisions.

Solar Calibrator is a field toolkit for solar installers and serious DIYers. Set the tilt and direction, size the array, battery bank and cables, check strings and shading, then hand the customer a PDF quote, all from one app. One purchase. No ads, no subscription, no account. TILT ANGLE Lay your phone on the panel and use it as a digital level. Get the best year-round angle for your latitude from published formulas, plus seasonal angles for summer and winter, and which way the panels should face. ORIENTATION A smooth, damped compass that tells you when the array faces the equator: south in the northern hemisphere, north in the southern. PV ARRAY SIZING Enter monthly usage in kWh and the share of the bill you want to offset. Peak sun hours are estimated from your GPS location, so there is nothing to look up. You get system size in kW, number of panels and roof area needed. BATTERY BANK Size off-grid and backup storage from monthly usage, backup hours and system voltage. Lithium or lead-acid, with depth of discharge and efficiency built in. WIRE GAUGE Get the right cable size, in AWG and mm², from current, run length and system voltage, for copper or aluminum. It checks both current capacity and voltage drop, and tells you which one set the size. STRING SIZING Find the maximum panels in series without exceeding the inverter's voltage limit on the coldest morning, using panel Voc and temperature coefficient. Add Vmp and the MPPT minimum to get a full min–max range for hot days too. LOAD AUDIT List appliances with quick-add presets and realistic hours per day to get total daily consumption before you size anything. SHADING CHECK Enter the height of a tree or building and its distance to see whether it will shade the panels at the winter solstice, when the sun is lowest.
