Marlborough's sunniest installer · Master Electricians · SEANZ member
Power your home with Marlborough sun.
Sunny Side Solar designs, installs and monitors residential solar panel and battery systems across Blenheim, Renwick, Picton and the wider Marlborough region. We handle everything from system design and council consents to certified electrical work and ten-year performance monitoring.
01 · Solar panels
Tier-one panels sized for your roof.
We install Jinko Tiger Neo 440 W and Canadian Solar HiKu6 455 W panels — both Tier 1, both backed by 25-year product warranties and 30-year performance guarantees. Every system is designed in-house using LiDAR roof data and Marlborough's 2,400+ sunshine hours to maximise your yield.

After a 6.6 kW install

Estimates based on a north-facing roof at 25° pitch in Blenheim with 1,450 kWh/kWp annual generation and a 34 c/kWh grid rate (Meridian, September 2026).
02 · Battery storage
Store the sun for after dark.
A battery lets you use your solar power at night, ride out grid outages and avoid peak-rate charges. We install three proven systems:
| Battery | Capacity | Backup | Warranty | Installed from |
|---|---|---|---|---|
| Tesla Powerwall 2 | 13.5 kWh | Full home | 10 years | $14,500 |
| BYD Battery-Box HVM 11.0 | 11.0 kWh | Essential circuits | 10 years | $11,800 |
| Enphase IQ Battery 10T | 10.1 kWh | Essential circuits | 15 years | $13,200 |
Every battery install includes a Sunny Side consumption monitor so you can track charge, discharge and grid import in real time from your phone.
