TiltSync vs SolarWiringSimLab

Perfect solar panel alignment in seconds. TiltSync transforms your iPhone into a precision alignment tool for solar panels. Perfect for DIYers, first-time installers, and anyone who wants professional results without the learning curve. Whether you're a homeowner installing rooftop panels, an RV enthusiast with a portable setup, or setting up your first off-grid system, TiltSync helps you maximize energy production with zero guesswork. **How it works:** Place your phone flat on your solar panel. TiltSync uses your device's accelerometer to measure tilt, the magnetometer for compass heading, and GPS for your exact location. The app calculates the optimal angle and direction, then guides you to perfect alignment with haptic feedback that intensifies as you dial it in. **Precision interface:** The main display shows a rotating compass card with your heading, a tilt indicator showing panel angle, and real-time digital readouts. It's not just functional, it's beautiful to use. **Three alignment views:** • Combined Dashboard — See tilt and compass alignment together on one screen • Tilt Mode — Classic bubble level for dialing in your angle • Compass Mode — Dedicated view for azimuth alignment with sun position marker **Three optimization modes:** • Year-Round — Set it and forget it. Best fixed angle for maximum annual production. • Seasonal — For adjustable mounts. Optimized angles for summer and winter. • Daily — Real-time sun tracking that updates every minute. Perfect for portable panels, camping, and off-grid setups where every watt counts. **Features:** • Precision interface — Compass, tilt indicator, and real-time readouts • Dark, light, and auto themes — Adapts to your preference or system setting • Color-coded feedback — Green when perfect, yellow when close, red when off • Progressive haptic guidance — Feel your way to alignment without watching the screen • Instant startup — Cached GPS location means no waiting on subsequent launches • Works fully offline — All calculations happen on-device • No account needed — Just open and align **Built for everyone:** No solar experience required. The intuitive interface guides you step-by-step, and haptic feedback tells you when you've nailed it — even if you've never aligned a panel before. High-contrast display works in direct sunlight. Dark mode for indoor prep, light mode for outdoor use. Whether you're on a roof, in a field, or at a campsite, TiltSync works where you work. Stop guessing. Start generating.

SolarWiringSimLab is a visual solar wiring planning app for RVs, camper vans, tiny houses, boats, cabins, and small off-grid power systems. The app helps you design and understand a simplified solar electrical system before building it in the real world. Instead of using separate calculators only, you can build a visual 2D wiring diagram and see how the main parts of your system connect together. Add solar panels, MPPT charge controllers, batteries, DC busbars, fuses, breakers, inverters, DC loads, AC loads, and wires. The Visual Wiring Canvas shows the main charging path and protected load branches, including solar panel to MPPT controller, MPPT to battery, battery to DC busbar, DC busbar to fuse or breaker, protected DC load branch, main inverter protection, inverter, and AC load. SolarWiringSimLab includes ready-made templates for common projects such as Basic RV Solar, Camper Van Power, Tiny House Starter, Boat DC System, and Off-Grid Cabin. Each template opens directly in the builder with a prepared system that can be reviewed, edited, analyzed, and saved. Built-in calculators help with important off-grid planning tasks: • Battery Runtime Estimate usable watt-hours, runtime hours, and runtime days. • Solar Size Estimate recommended solar wattage from daily energy use, peak sun hours, and system loss. • Wire Size Find a recommended wire size using voltage, current, cable length, and allowed voltage drop. • Fuse Size Estimate a recommended fuse rating. • Inverter Size Estimate inverter wattage, surge needs, and battery current draw. • Voltage Drop Check estimated voltage loss through a cable run. The system analyzer helps identify common planning issues, including missing battery protection, missing DC busbar, missing DC branch fuse or breaker, missing inverter protection, missing MPPT controller, low solar production, insufficient battery capacity, inverter overload, surge power risk, MPPT input voltage problems, and excessive voltage drop. The Project Summary screen organizes key results in one place: system voltage, total solar power, battery capacity, usable battery energy, daily load, estimated runtime, daily solar production, warnings, wiring preview, wires, fuses, and breakers. The Learn section explains solar basics, battery capacity, inverter sizing, wire sizing, fuse protection, and common wiring mistakes in simple language. It is useful for beginners who want to understand why low-voltage systems require careful wire sizing, why fuses protect wires, and why daily energy use must be compared with solar production and battery capacity. Settings let you customize default system voltage, wire unit, AC voltage standard, temperature unit, theme mode, and language. The app supports 12V, 24V, and 48V planning, mm² or AWG wire units, 120V AC or 230V AC standards, Celsius or Fahrenheit, and light, dark, or system theme mode. Saved projects are stored only on your device. No cloud account is required. Project data is not stored on an external server. If you delete the app, saved project data will also be deleted. SolarWiringSimLab is designed for planning, learning, comparison, and early design exploration. It helps you organize components, estimate performance, understand energy flow, and spot common wiring risks before purchasing parts or building a system. SolarWiringSimLab is an educational planning tool. It does not replace certified electrical design, professional installation, code compliance review, or inspection. Always verify real-world wiring, fuse sizing, breaker sizing, cable ratings, battery installation, inverter installation, and electrical safety with a qualified professional before building or modifying an actual electrical system.
