 Solar Hot Water or Photo Voltaic Power

Solar 
Description

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.
Considerations

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 -$11,000

Solar 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
