Ka-Saver — turning solar installs into a savings dashboard

SolarMaxx sells solar, but the value is invisible after install. Customers forget the ROI, referrals dry up, and support fields the same 'is it working?' question all day. There was no single place a client could open and see their own savings.

One screen per household: energy produced, pesos saved this month, lifetime ROI, and a nudge to refer. Owner-side: a roster of all sites with health flags. We modelled the savings math once, kept money in centavos, and pinned everything to Asia/Manila.

1. Per-client dashboard with monthly production and peso-savings, computed server-side so the numbers can't drift.
2. Installable PWA so customers keep it on the home screen — no app store friction.
3. Owner roster monitoring ~600 sites with health flags surfacing underperformers before the customer calls.
