Should you wait to put Solar on your roof? Checkout the election 2026 solar policy breakdown here
With a home solar system, you can use daytime power generation to fuel your driving for a fraction of grid prices – in many cases reducing charging costs by up to 70–85%, and even reaching $0 per km once your system is paid off.
The average EV uses around 15–20 kWh per 100 km, meaning grid charging can quickly add hundreds of dollars a year to your power bill. Solar flips that equation, turning your roof into a fuel source and protecting you from rising electricity prices.
Beyond your EV, a well designed home solar system can cut total household energy bills significantly, while increasing your energy independence and resilience for decades to come.
Our experts will design a system tailored to your home and lifestyle, so you get the most out of your EV.

Assumptions for these calculations.
RUC is based on 2027 charges ($768). Petrol consumption based on 7.5 litres/100km. EV power consumption is based on the evbd.nz database of WLTP consumption ratings for all EVs. Petrol costs based on $3.28/litre (Gaspy.nz, Unleaded 91, 08.05.26). RUC, Petrol and EV power consumption is based on 10,100 km of travel per year (carjam.co.nz, hatchback avg).
Vehicle-to-Everything (V2X), or Bi-Directional charging is an exciting technology that allows compatible electric vehicles to use their internal battery to help power your home, store excess solar energy, and support greater energy independence during outages.
Sigenergy is leading the adoption of V2X in New Zealand with their SigenStor DC Charging Module.
As a Sigenergy Platinum Installer, Lightforce Solar are proud to offer DC Charging Module as a powerful EV charging and V2X solution that’s ready for the future.
The Sigenstor DC Charging Module integrates easily into the Sigenstor stack, alongside your Sigenstor inverter and home batteries. This allows you to rapidly charge your EV or PHEV directly from your batteries with high-speed, efficient DC charging.
The Sigen EV AC Charger allows you to charge your EV directly from your Solar inverter with rapid, and easily configurable charging options, giving you control over how and when your EV charges.
Wall mounted, and fanless, the Sigen EV AC charger is a fast and user friendly option to keep your electric vehicle charged efficiently.
For New Zealand homeowners with solar, or who are making the switch, the Sigenergy SigenStor DC Charging Module opens the door to these future-ready capabilities within a single, integrated energy ecosystem.
At Lightforce Solar, we’re proud to offer the SigenStor platform, including access to V2X-ready technology. Sigenergy has conducted extensive V2X testing and trials across multiple countries and a growing range of EV brands and models. As compatibility continues to expand, we encourage customers to review the latest information directly from Sigenergy’s website for current vehicle support and testing updates.
Please note that V2X functionality is not available on all EVs. Vehicle compatibility, software support, and battery warranty conditions vary by manufacturer.
EV owners should confirm V2X capability and any warranty requirements directly with their vehicle manufacturer.
