What’s Involved in Commercial Solar Installation?

A typical commercial solar install begins with a tailored system design based on your site's layout and energy usage. We assess your roof structure (or ground space for larger systems), evaluate shade and solar orientation, and size your PV system for current and future needs.

Once designed, we manage the full process:

Most commercial solar systems in Auckland range from 20kW to over 100kW in capacity. The average cost to install solar panels on commercial buildings can vary depending on system size, roof type, and whether battery storage is included. We provide obligation-free, itemised quotes so you know exactly what’s involved.

Why Choose Ester Electrical?

With extensive experience in commercial and industrial energy projects, Ester Electrical is one of Auckland’s most trusted electrical contractors. Our team holds accreditations from MCS, Tesla, and Enphase, and we’re well-versed in the specific requirements for installing solar across business premises, educational facilities, and council sites.

Unlike many solar companies, we don’t outsource. Our own electricians and project managers ensure high standards, regulatory compliance, and seamless project delivery—on time and within budget.

Do I need council consent for solar?
In most cases, rooftop solar doesn’t require consent in Auckland. However, for large-scale, protected, or heritage-listed buildings, we’ll manage the entire approval process as part of our turnkey service.

We have worked alongside Kyle & the team at Ester Electrical for many years now. As the main contractor to them they have delivered comprehensive electrical services to us both in the civil space & general electrical work. They are very knowledgeable, think outside the box and are always reliable when it comes to a construction programme. As a subcontractor we have been treated with the upmost respect and valued for our knowledge and expertise in helping their civil projects come to life. Not to mention payment is always made on-time, every-time. Couldn't recommend anyone else to have on your team in the commercial & civil electrical space. Thanks Ryan Ruthe Managing Director - Next Level Civil Limited

Ester Electrical performed the task of connecting the house electricity supply to the slimline PROMAX water tank pump. They completed the job to a high standard, were well mannered and worked diligently. They took the time to listen and respond to any concerns or queries that I had. They problem solved their way around a tricky wiring situation and got it sorted! It was a pleasure doing business with Ester Electrical and I would certainly recommend them for any service which they offer.

Kyle added feature lights to our outdoor patio, which enhance the attractive vine leaves and provide soft lighting for entertainment. He also installed a BBQ spotlight so the chef can see what's cooking. Kyle added extra lights to our garage, increasing visibility. He left the place spotless. Great job!!

Ester Electrical were fantastic - Sheryl in the office is very organised and Sam the electrician that has looked after us every time is onto it- informative and prompt. They were prepared to come to my apartment in the city where other companies declined due to parking difficulties, and also did a fantastic job on the lighting repairs in a turn-of-the-century bungalow, fixing a job a previous electrician left half done. No complaints, no fuss, good value and great service. Will use them again.
