Commercial Solar Auckland

Turn unused roof space into low-cost power.

Commercial Solar solutions designed around how your business uses power

Commercial solar can meaningfully cut daytime power costs for Auckland businesses, especially where energy use peaks during business hours.

Astech Solar, backed by 31 years as Master Electricians, reviews your usage, roof space, switchboard and future EV charging needs before recommending a system, so the numbers are based on how your business actually operates, not a generic sales package.

Why Commercial Solar makes sense right now

Rising power prices are putting pressure on operating costs across Auckland, and businesses are under increasing pressure to show better energy decisions.

Commercial sites often have an advantage here that homeowners don't: most use the bulk of their power during the day, exactly when solar is producing.

This isn't a fringe technology anymore. In Australia, rooftop solar now generates more electricity than the country's entire coal-fired power fleet.
A clear sign of how quickly solar has moved from alternative to mainstream infrastructure for homes and businesses alike.

Your roof could already be one of your best unused business assets.

Built around your business, not a generic package

We start with your Power Bill

Before we talk panels, we look at your actual usage data. This tells us how much of your daytime load solar can realistically offset, and it's the difference between a system that performs and one that just looks good on paper.

Daytime usage makes the numbers work harder

Warehouses, retail sites, offices and industrial premises typically draw the most power during business hours. That timing overlap is exactly what makes commercial solar returns easier to model with confidence.

Planned for EV Charging and future load

If fleet or staff EV charging is on your radar, it needs to be planned into your system and switchboard now, not added as an afterthought later. We design for where your power use is heading, not just where it is today.

Who we work with

Landlords

Landlords and building owners

Solar can lower operating costs, help attract and retain tenants, and in some cases be structured as part of a lease arrangement. We can also handle any switchboard or EV charging upgrades the building needs alongside it.
Tenants

Tenants and business owners

If you lease your premises, solar can still make sense. We'll help you understand what's possible within your tenancy, and where finance options may help ease the upfront cost.
Property and Operations Managers

Property and operations managers

One point of contact for the whole project, from initial site review through to installation and ongoing service, means fewer moving parts for you to manage.

One Team for the whole job

Astech Solar can manage solar panels, battery storage, EV chargers, switchboard upgrades and any wider commercial electrical work your site needs.

There's no juggling separate contractors for the parts of the job that don't fit neatly under "solar."

Frequently Asked Questions

For sites that use most of their power during business hours, commercial solar can offer a strong return by directly offsetting daytime grid usage. The right answer depends on your roof space, usage pattern and switchboard capacity, which is exactly what a commercial solar review is for.

Costs vary depending on system size and your building's electrical setup. Astech has installed commercial systems from 10kW through to 250kW, so we can scope a system and cost estimate that matches your specific site.

In some cases, yes. This depends on your specific lease structure and arrangement with tenants. We can provide the technical detail you need to have that conversation with your legal or financial advisor.

Yes, provided it's planned in from the start. We assess your switchboard capacity and future charging needs alongside your solar system, so both work together without overloading your building's supply.
