SOLAR IN WAIKATO

Solar Made Simple
for Waikato

The Waikato is dairy country, and it generates a good share of the nation's power: the hydro chain on the river, Huntly, and the geothermal field up at Taupō. It is also good country to put panels on, mainly because there is room. Wide town sections, lifestyle blocks and farm roofs give you a genuine choice about where an array goes and which way it faces.

EFS Solar is based at 35 Clem Newby Road, Burbush, in Hamilton, so the Waikato is home ground rather than an outlying service area. We work right across it, from Thames and Waihi through to Te Kūiti and Taupō. Every system is designed from an on-site assessment, and installed by electrical workers licensed under the EWRB. Panels are Tier 1, with warranties of up to 30 years.

WHY GO SOLAR IN WAIKATO?

  • One installer covers the whole region, so a Te Kūiti or Thames job gets the same site visit, the same standard of install and the same aftercare as a Hamilton one.
  • Different parts of the region sit on different networks, WEL, Waipā, Powerco, Counties Energy, Unison and The Lines Company among them, and we handle the connection application for whichever one covers you.
  • Waikato homes range from compact town roofs to lifestyle blocks running sheds, pumps and bores, so system size is set on site rather than from a standard package.
  • Your lines company sets the limit on what you can export, and since the 2026 change most single-phase homes sit at 10kW, so we confirm the figure for your address first.

Every EFS Solar installation is carried out by licensed electrical workers, uses Tier 1 panels and inverters, and is backed by warranties of up to 30 years, with $0 upfront options available. We're proudly New Zealand-owned.

Residential Solar in Waikato, Common Questions

How much does a residential solar system cost in New Zealand?

It depends on your roof, your power use and whether you add a battery, so we quote every system individually after a free on-site assessment rather than advertising a one-size-fits-all price. $0 upfront payment options are available, and several major NZ banks offer low- or zero-interest green loan top-ups for solar.

How much power will solar generate at my place?

As a rule of thumb, a well-sited system in New Zealand generates around 3.9kWh per day for each kilowatt of panels, averaged across the year, so a 6.6kW system produces roughly 26kWh per day. Your roof orientation, tilt, shading and local climate all move that number, which is why we design from an on-site assessment.

Who installs the system?

All electrical work is carried out and certified by licensed electrical workers registered with the Electrical Workers Registration Board (EWRB). We use Tier 1 panels and reputable inverters, backed by warranties of up to 30 years on panel performance.

What happens to the power I don’t use?

Surplus generation is exported to the grid and your electricity retailer pays you a buy-back rate for it. Rates vary between retailers, so it pays to compare plans. We can point you at the options that suit solar households when we design your system.

How big can I go on single-phase power?

Without a battery, the practical maximum on standard single-phase power is 13.3kW of panels, a 10kW inverter oversized by the allowable 33%. Add a battery and the allowance grows to as much as 200%, or up to around 20kW of panels.
