Why Zero
We come to you. No call centres. Straight up advice.
Every quote starts with a cuppa. We'll visit your home to assess your roof and switchboard. Then after a chat about how you use power, we give you our honest advice.
If you don’t need a battery, we’ll tell you. If solar doesn’t stack up for your place, we’ll tell you that too.
Solar, explained
Understand it before you buy it.
Solar can be confusing. We make it simple, start here.
Do I need a battery?
Honestly, maybe not. It depends where you live and when you use power. Christchurch city and rural Canterbury get different answers.
Batteries explained →What is kW vs kWh?
One measures how much electricity is used, the other how much is used over time. Two minutes here saves you an hour of confusion with any solar quote.
Learn the language →Can I sell solar power?
Grid export means selling excess power to your solar company, allowing your roof to earn while you’re out.
