Solar Payback Meter

Move the slider to your average monthly TNB bill. Every figure updates live — recommended system size, install cost, payback period, and how solar compares to grid power per kWh. Counts self-consumed power only, on purpose.

Illustrative estimate, not a quote. Assumes 1400 kWh/kWp/year yield, a 25-year system life, and counts savings from self-consumed solar power only — this deliberately excludes NEM export credit, so it's a conservative floor rather than a best case. Your roof, shading, orientation and actual usage pattern will change the real numbers. An installer's site assessment gives you the figures that actually matter.
