A little guidance goes a long way

Feel confident about going solar

Clear answers. No jargon.

Choosing the right installer

Check MCS certification, get at least three quotes based on a site survey, and ask about equipment, warranties and aftercare.

Understanding the cost

Your roof, system size and battery storage all affect the price. Compare itemised quotes for the same specification, not just the total.

Connecting to the grid

Your installer should handle the network operator paperwork. Smaller systems use G98 notification; larger systems may need G99 approval first.
