Sun Biller

Sun Biller helps rooftop solar homes log meter readings and estimate monthly electricity bills — simply and clearly.

What you can do • Log lifetime generation and consumption from your inverter / meters
• See today’s solar production, home use, and net surplus or deficit
• Get an estimated bill for your state and domestic tariff category
• Fill missed days with equal-split estimates so charts stay consistent
• Export a monthly PDF report to share or keep for records
• Set reminders so you don’t forget to log
• Use as a guest, or sign in with email / Google to keep data safer across devices

Built for Indian homes Choose your billing state and sanctioned load. Estimates use published domestic tariff slabs and are for guidance only — always rely on your official utility bill for payment.

Private by design Meter photos and PDF exports stay on your phone. Cloud sync (when you sign in) backs up profile and reading numbers only.

Start with a baseline reading, then log once a day. Sun Biller does the rest — day totals, trends, and a clear bill estimate.
