About this app

STOP GUESSING. START CHARGING.

Solar Spotter is the solar advisor for off-grid 4WDs, caravans, motorhomes, vanlifers, overlanders and boondockers — anyone who relies on portable solar. Live local conditions, precision panel alignment, and a direct read on your battery — we tell you when to charge, how to align, and what your battery's actually doing, so you get the most charge out of every hour of sun. Your setup works hard so you can relax and enjoy the outdoors.

FREE — NO ACCOUNT, NO SIGNAL NEEDED:

- Read today's solar day at a glance — current irradiance, efficiency against the physical max for your spot, cloud cover, and temperature.
- Set up for the hours you want to charge — intuitive solar compass with azimuth, altitude, and optimal tilt, plus highlighted bands for charging now, +3hr, and +6hr.
- Plan around peak solar — full-day sun path chart from sunrise to sunset with peak hours marked.
- Catch what's coming — 3-hour weather snapshot.
- Bush Bash offline mode — works anywhere. No signal? No worries.

CHARGE SMARTER. NOT LONGER.

Pro turns your phone into a full solar advisor — here's everything you get:

— KNOW WHAT'S ACTUALLY HAPPENING —
• Battery Bluetooth (BETA) reads your battery's built-in monitor directly over Bluetooth. See what's pushing in (solar, your DC-DC, or both) and what your fridge or other gear is pulling out — without conflating them. Built for batteries that use a JBD or JK monitor (BMS) — confirmed on iTechworld, with more being verified.
• Daily Battery Tracker projects your sundown % and runs a sunrise check from your current charge and system draw.
• Estimated Output runs your real panel + battery specs against live conditions and shows hourly wattage, recharge rate, and projected daily harvest. Updates every 15 minutes.

— CHARGE IN THE RIGHT HOURS —
• Best Charging Window (BCW) rolls through the day on live weather. Set a duration, pick a custom window, or let the app find the optimal one.
• 3-day solar outlook — see what the next few days charging looks like at your spot.
• Hyperlocal 15-minute weather — YOUR exact spot, not a regional average.

— SET UP TO THE DEGREE —
• AR Alignment shows the exact direction and tilt with audio + haptic feedback to help lock it in. A real game changer for portable blanket and panel users — about 25% more charge than guessing the angle by eye. Reposition with confidence each time, or set once and forget for the day knowing you've optimised your charging for today's conditions.

— PLAN THE WHOLE TRIP AROUND SOLAR —
• Trip Planner: multi-stop solar outlooks so you can see what charging conditions are like where you're headed, not just where you are now.
• Your own trip archives and campsite notes. Record the great (and the not-so-great) parts of the trip — future you will thank you.
• Use different equipment for different trips? Save multiple panel + battery profiles — switch between rigs in a tap.

Designed for the real world. Works in the outback, at the beach, in the mountains — anywhere you set up camp. Every calculation runs on-device. No reliance on cloud services or mobile coverage.

Our Honesty — live-weather, physics-based, real-conditions-aware outputs for your exact spot, right now. Plain talk on what we can and can't tell you.

Your Privacy — no ads, no tracking, no analytics, no accounts. Your spot stays yours.

What’s new

NEW: Battery Bluetooth (BETA).

Pair your battery's built-in monitor over Bluetooth and the app reads your live state-of-charge directly. The sundown projection and sunrise check now anchor on a real reading. Built for batteries using a JBD or JK monitor (BMS) — like LiTime, Fogstar, iTechworld, Power Queen, Photonic Universe, KickAss and Supervolt. Confirmed on iTechworld; verifying more.

Plus dozens of small polishes across the battery and Bluetooth flows.
