    Commercial solar and battery · Lyneham ACT

    Thai Temple in Lyneham

    20 kW Solar and a 20 kWh battery on a temple complex whose bills were being driven by the cost of heating it.

    About this job

    Understanding the high bills

    Community members approached us about the temple’s rising energy costs. The large, draughty building needed substantial heating, particularly on winter mornings when solar generation is limited. Understanding that pattern helped shape the system design.

    Using storage to manage peak demand

    Commercial tariffs can include charges based on peak electricity demand as well as total usage. The 20 kWh battery can supply stored energy during busy periods, helping reduce demand on the grid and the associated charges.

    Upgrading the meter board

    The project included a meter board upgrade to support the new solar and battery system. We assessed the existing electrical infrastructure first, so the required work was included from the start.

    Helping beyond the installation

    We also donated a portable battery pack and arranged an assessment with a certified energy assessor. This gave the temple practical next steps, including opportunities to improve insulation and seal draughts, reducing the energy needed to keep the building comfortable.

    How we work

    The job above ran the way every Sunstak job runs. From your first energy bill to switching on your system, we guide you through every step.

    1. A cyan sign board standing on a driveway, lettered sunstak above the words THIS HOUSE IS POWERED BY SUNSTAK with the address sunstak.com.au along the bottom, the front of a white car in the left foreground and timber steps with two orange traffic cones behind it

      Share your energy bills

      Send us a summer bill and a winter bill, and tell us when you use the most energy. This helps us design around your household.

    2. Two men reaching to shake hands on the front path of a brick house with solar panels on its roof, one of them in a dark t-shirt carrying a circular cyan mark, while a woman stands in the open front doorway behind them

      Get ready for installation

      We explain what to expect on the day, including any planned power interruptions and how long they should last.

    6. A single-storey timber-clad house on a dry rural block at golden hour, its pitched metal roof covered by a full array of solar panels, a white battery standing against the timber wall beside a car charger with its cable coiled, a dark grey car parked on the gravel driveway and gum trees and low hills behind

      Enjoy ongoing support

      We get your system running and set up your monitoring app. For questions, service or warranty help, the same team is here after installation.

    • Tesla Powerwall 3 ACT 2906

      The spot stayed, the battery changed

      The standards decide where a battery can sit: clearances, the wall behind it, and the run back to the switchboard. Here the position the owner wanted stayed, and the battery changed to one rated to live outdoors. A plumber capped a disused gas line on the same visit.

      Everything was smooth from the initial quote, through to the installation. There was some initial back and forth about which type of battery to install and location. In the end my preferred location was not going to meet standards which then meant having to change the brand of battery to one that would be more suitable outdoors. This was all handled well by Michael and the team.

    • Second Tesla Powerwall ACT 2600

      A second battery, and the first one fixed

      The owner already had a battery from another company, installed a year earlier, and wanted a second one beside it. We inspected that first install as part of the job. Faults nobody could see at quoting turned up on the day, and we corrected them at no charge.

      Sunstak have just added a second Tesla Powerwall battery to my system, which had been installed a year ago by another provider. … The quality and professionalism of the installation was particularly impressive. Several deficiencies in the installation of the existing battery by my previous supplier were rectified without cost or question, even though some were not apparent at the time of quoting.

    • Battery retrofit ACT 2905

      Quoted after seeing the home

      Retrofitting storage to an existing array depends on things only a site visit shows. The inverter already fitted, spare ways in the switchboard, where a battery can legally sit, and how far that is from the meter. Some of the companies asked to quote this job never visited the home.

      I reviewed all of the companies on the ACT Government approved list for a solar battery to add to my existing solar panel system. I sought quotes from the 6 best rated companies. From the 4 quotes I received I chose SunStak. The main reason I chose them was because they were the most responsive, helpful and reasonably priced, a couple of the others didn't even visit the house before quoting.

    • Commercial rooftop solar Wanniassa ACT

      A school hall in Wanniassa

      A school roof is a set-out problem with a deadline attached. We planned, delivered and commissioned the array inside the break before the new term. Somebody else coordinated the site. 40 kW of panels onto one long hall roof, in five days, with six people on it.
