Cut your home electricity bill 30-50% with grid-tied Solar Rooftop
Homes, apartments, and small resorts cut their daytime electricity bill 30-50% with a right-sized grid-tied rooftop system — installed by Microgrid Technology (a LEONICS company) and tracked via the Solar Insight Tool, with an optional battery for outage backup.
Design figures for a system sized to this use case. What a given site actually gets depends on its load shape, the PV and battery sizing and its tariff — the worked examples below show the inputs.
The Challenge
Home electricity bills keep rising. Owners want lower bills with a clear payback — but worry about roof safety, the right size, and whether solar really pays off.
- Rising home tariff — Residential tariffs keep climbing — especially in the daytime when aircon and appliances run together.
- Paying peak rate at peak sun — The sunniest midday hours are exactly when the home buys grid power at full rate — power the roof could generate itself.
- Wrong size wastes money — Oversizing wastes budget, undersizing under-delivers — most homes never measure real load before installing.
- Roof and safety worries — Owners worry about roof load, waterproofing, and inverter safety.
- Unclear payback — Without monitoring, savings are invisible and the real payback stays uncertain.
The array feeds one grid-tied inverter; the house consumes first and only the surplus passes the meter. A battery can be added on the DC side later.
