Solar Monitoring App Development

I’m creating Shri Solar, a cross-platform mobile app that lets individual homeowners track every watt their rooftop array generates. The build targets both iOS and Android with a single Flutter code-base.

Core functionality I need implemented:
• Live solar analytics streamed from inverters or data loggers to an intuitive dashboard.
• Real-time views of energy generation, efficiency, and cumulative electricity savings, paired with environmental impact stats.
• Remote plant monitoring so users can check their system’s health anywhere.
• Automated maintenance alerts and fault notifications that proactively reduce downtime.
• Secure sign-up and login with role-based access for owners, installers, and support staff.
• Daily, monthly, and yearly production reports downloadable as PDFs or shareable links.
• Responsive UI/UX that feels native on phones and tablets.

Please design the Firebase (or equivalent) back-end for authentication and data storage, integrate the necessary APIs or MQTT streams from the solar hardware, and deliver clean, well-documented code ready for App Store and Google Play submission.

Acceptance criteria will be a working beta on TestFlight and Play Console showing accurate live analytics from demo data, with all alert mechanisms firing appropriately.
