Solar installation process

We've made it simple to switch your home onto clean solar power. 

The solarcity journey

We’ll support you throughout your solar journey. We'll be there over the phone, via email and with visits to your home. As a proud carboNZero company we’ve designed the whole process to be paperless. This means all communications, contracts and updates will happen via email, making the process as hassle free as possible.

solarZero explained 

Simply fill out our online enquiry form or call us on 0800 11 66 55. Once you've completed a short survey we'll have a good idea if your home is a good fit for our solarZero energy service. We'll then call you to get more detailed information and to explain how we can make our service work for you. We'll also ask you to send us a copy of recent power bill so we can estimate your solarZero savings based on your home's current energy use.

Agreement to proceed 

Once the initial assessment has been completed with one of our energy specialists and the best solution for your home agreed, an agreement will be sent to you using an online signature service. We will also set up direct debit agreements for your monthly energy service fee and your grid power bill,

Energy audit and in-home site assessment 

Your energy advisor will help you complete an energy audit of your home so that we can create a Personalised Energy Plan for you. It will give advice on how to maximise your solar use along with ways to improve your home's energy efficiency. Your advisor will also arrange for one of our site assessors to visit your home at a time that suits you. The main aim is to confirm where and how the system will be installed and to look at the options for adding battery storage.

Full solution review and personalised energy plan  

After we've reviewed the results of your in-home assessment we'll confirm the best solution for your home. We'll provide an estimate of the savings you can make by switching to our solarZero energy service. We'll also supply a Personalised Energy Plan with lots of handy info on how to maximise solar power in your home and reduce your overall energy use.

Installation and activation 

Installing the system usually takes between 4 and 8 hours. We meet you at your property, on the agreed day and time, to fit the solar panels, hook up the electrical connections and setup the monitoring and control platform. The system is switched on and starts powering your home using the sun's clean energy.
