Residential solar

Home solar designed around how your household uses electricity.

A useful solar design starts with your electricity use, roof and future plans. Calibrasia uses those inputs to shape the conversation around system size, inverter choice, panel layout and whether battery storage should be considered now or later.

What shapes the design

The right solar size depends on more than roof space.

Two homes with similar roofs can need very different systems. Consumption, timing, export limits, equipment choices and future loads all change the design brief.

Your electricity bill and when the home uses the most power
Roof orientation, available space, shading and practical site constraints
Panel and inverter configuration, including room for future loads
Plans for batteries, an EV, electric hot water or other electrification

System sizing

Start with the load you want solar to serve.

Daytime consumption is especially important because solar generation is most valuable when it can be used directly in the property. Larger future loads can also change what makes sense today.

Review recent electricity usage rather than relying on a generic household average
Consider seasonal loads such as heating, cooling and pools
Allow for future EV charging, electric cooking or heat-pump hot water where relevant

Proposal clarity

Know what is being proposed and why.

A solar proposal should make the important assumptions visible so you can compare options on more than price alone.

Battery storage

Battery storage for evening use, backup goals and better use of rooftop solar.

A home battery can shift solar energy into the hours when the sun is down, but capacity and configuration should be matched to your generation, household demand, tariff, existing equipment and backup expectations.

Solar + battery

Plan solar generation and battery storage as one system from the start.

Designing solar and storage together makes it easier to align daytime generation, evening demand, inverter architecture, backup goals and future household electrification.

Solar & battery options

Use system sizes as starting points, not off-the-shelf answers.

Indicative solar and battery configurations can make comparison easier, but the final system still needs to reflect the property's electricity use, available roof space, equipment compatibility and future plans.
