Why rooftop solar now?

Direct savings
For many households, a rooftop system cuts 20–30% off the electricity bill within the first year. That shift becomes a permanent operating cost reduction as utility prices rise.

Predictable energy cost
Once installed, solar fixes a large component of your energy expenditure. With modest tariff inflation, the value of every kWh generated increases over time.

Faster payback than you think
Typical payback ranges from 3–7 years depending on system size, subsidies, and the retail tariff you currently pay.

Environmental and social benefits
Lower carbon footprint and local energy resilience.

How to size a rooftop system for your home

Calculate real consumption
Use the last 12 months of bills to find annual kWh. Monthly fluctuation matters — size for average use unless you want full self-consumption.

Assess usable roof area
Typical modern modules require ~4–6 m² per kW depending on module wattage and tilt. Include obstructions (chimneys, vents).

Targeted coverage
Many homeowners choose to offset 50–90% of daytime consumption rather than 100% of total consumption to reduce cost and maximize economic return.

Choose the right inverter & panel
Reliability and warranty matter. Higher-efficiency panels reduce roof space requirements.
