I built my own solar dashboard because the Solarman app was missing so many features (free to use, feedback welcome!)
Hi everyone! Solar owner here. I've been using the Solarman app to monitor my system and honestly, it's okay for watts and graphs, pero after that wala na. It can't answer the questions I actually care about: magkano ba natipid ko this month? Kailan ba babawi yung system sa gastos? May sira ba sa taas na hindi ko napapansin?
So I built my own app on top of it. It's called Sinag, and it uses your existing Solarman login, so no new account needed. Everything gets computed from the same inverter data.
Mga favorite ko:
🌟 ROI / payback tracker - this is the reason I built the whole thing. Enter your system cost and install date, and it tracks lifetime savings, percent paid back, and a projected break-even date. Sagot na yung "bumawi na ba yung solar ko?"
💰 Bill page na naka-align sa Meralco cycle mo - not the calendar month. Cycle-to-date savings in pesos, plus a weather-aware forecast of your total for the cycle
🔔 Fault alerts with push notifications - it watches your system and taps you on the shoulder pag may problema: offline, zero production sa umaga, overheating inverter, or unti-unting bumababa yung performance. Works kahit closed yung app
The rest of the features:
- Live power flow diagram (solar, house, grid, real time)
- Energy explorer with 5-minute detail, any date range
- 12 cycles of savings history
- System health check that removes weather from the equation, so a cloudy month won't look like dying panels
- Compare any two periods (before and after ka nag panel cleaning, bagong aircon, etc.)
- Full inverter telemetry pag gusto mo yung detalye, down to DC string voltages
- Accurate Meralco rates per month, or set your own kung ibang distributor kayo
- Installable as an app on your phone, with light and dark mode

It's free, sign in lang with your Solarman account.
Quick note on security since I know logging in with your real account sa third-party app is a valid concern: your password never leaves your browser as plain text. It gets hashed on your device first (same hash the official Solarman app sends), and the app never stores your password anywhere. Solarman mismo yung nag-a-authenticate. And honestly, wala rin akong balak (o dahilan) para kolektahin yung credentials niyo. Useless din naman sa akin, solar monitoring data lang ang laman niyan. Read-only din lahat, it only pulls your monitoring data.
I'd really love your feedback - anong features yung wish niyo sana meron? Anong kulang pa? I'm actively building this so feature requests are very welcome. Salamat! 🌞
