Roof and consumption

Orientation, usable space and consumption patterns help determine the system size. More panels do not always make a system better suited to your home.

What a quotation should include

Panel and inverter makes and models, mounting structure, safety devices, installation work, included paperwork, taxes and warranty terms. Ask for the assumptions behind the generation estimate too.

From assessment to commissioning

The professional checks feasibility, finalises the quotation and sets out the applicable municipal procedures and registration. Roof condition and access also need checking.

Do I need a battery from day one?

Not necessarily. First consider how much of your consumption coincides with solar generation. If you may add storage later, check compatibility at the design stage.
