Heat retention and cooling in summer.
HBRC would be providing a low interest rate in the market, while still recovering costs.

Solar hot water or photo voltaic power have different systems - one piped, one cabled. Cable is easier to retro fit.
Most installs are new build rather than retrofit, and would not qualify for HBRC financial assistance.
This is a (relatively) young market, restrained by power company purchase rates and payback period; the more you spend, the longer it takes to pay for itself.
Only one funding package is available per dwelling (rateable unit).
|Rationale||Increased use of solar technology reduces demand on the grid. Early adopters have made significant returns on feeding back to the grid. The market has professional leadership and regulation.|
Installation is governed by a professional body www.seanz.co.nz. Any new supplier has to go through a process to be a member.
Photovoltaic (PV) system – no council consent is required but it must have authorisation from Unison. Unison fee is $160 (Oct 2018).
All PV systems installed are monitored by Installer for faults.
Battery technology has yet to hit volumes that reduce price. Current average starter system is $6,000 -$11,000Solar City are gaining market share, where no charge for a maintained system, but fixed usage charge is tied in for a 20 year contract.
|Benefit||Reduced demand on grid
Resilience if network supply goes down
