Solar companies could be in for a boost if National gets re-elected.
The party is pledging to have a scheme offering homeowners low-interest loans to let them switch to solar, batteries, insulation - taking away big upfront costs.

Rewiring Aotearoa CEO Mike Casey has voiced support for this move.
"We've been asking for this for a long time and it's being delivered. So I'm thrilled."
