About

RenewCo Solar was founded in March 2021 in NSW by father-and-son team Mark Summerville and Mathew Summerville. Servicing the Sydney area, RenewCo supplies and installs solar power systems, battery storage, EV chargers, and heat pump hot water systems. RenewCo Solar is an NETCC and SAA approved engineering and installation organisation dedicated to one outcome: long-term energy independence for Australian homes and businesses.

In 2025, we welcomed Better Call Solar into the RenewCo Energy group, combining their six-star boutique service with our award-winning scale. The merger gives clients the best of the best in solar and battery solutions. We have also expanded our workforce model to meet growing demand. While our core team of 50 in-house staff remains, we now employ a hybrid model, partnering with select expert contractors to increase our installation and support capabilities. This hybrid approach allows us to serve more customers without compromising on quality or service.

Why Choose RenewCo Solar?

  • Integrated Expertise: Our dedicated team of 50 electricians, engineers and project managers—reinforced by the Better Call Solar crew and a network of trusted contractors in a hybrid delivery model—ensures every project is delivered from consultation to commissioning with top-tier workmanship and efficiency.
  • Single Point of Truth: One brand, one Australian support desk, streamlined warranties, and a 10-year workmanship guarantee for all RenewCo systems (including legacy Better Call Solar installations).
  • Group-Level Buying Power: Consolidated procurement secures Tier 1 technology at preferential pricing—savings which we pass on to you.
  • Scalable Delivery: Whether it’s a 6.6 kW starter array or a 200 kWh battery stack, each job is executed by accredited crews (in-house staff and our vetted contractors) following the same high standards. We maintain end-to-end accountability on every project—ensuring continuity, safety and quality from start to finish.

Lacking attention to detail, craftsmanship, and follow through

Sales and quoting was fine but installation and support has been disappointing.

Our installation was deemed "easy" due to ground level access in the garage and short cable runs. We have an existing PV system but hired RenewCo to add a Sigen battery.

Lack of planning and a rushed schedule led to many mistakes, including improperly drilled holes in load bearing walls and unused holes in mains enclosure. 50% of holes drilled were caulked over using Sikaflex. Isolator switch mounted upside down. New PV strings from isolator switches wired backwards. Sloppy and rushed conduit work.

On the second day of installation, wiring was "finished" and system activated. Guys left but 3 of the 4 PV strings weren't working. After initially brushing this off as a warranty issue with Sigenergy, I continued to escalate with support they came back and fixed the remaining PV strings on a 3rd installation visit.

Since then I've received no concrete timeline for when the installation will be finished. A number of items remain including: STC certification, code compliance, fixing mistakes like sealing up the extra holes in the mains enclosure, etc. This was meant to be a half day job, but installation is still not complete over a month and 3 visits from the initial installation date.

Most of the issues stem from the original installation team, who did not communicate well and rushed to attempt completing the install in a half day even though they arrived 2 hours late.

For a company that proclaims to have exceptional after sales support, my experience has been the opposite. I have had to chase RenewCo through every step.

Given my experience, I do not recommend RenewCo solar. If you do choose to work with RenewCo, ask for an experienced installation team, request a morning time slot, and get a detailed design run-through before the first hole is drilled.

Sincere thank you to Ned with SolarQuotes who has provided guidance through this process.

Fantastic company, super professional

I chose RenewCo Solar as their sales person was the most knowledgeable and willing to put the time and effort to calculate and explain to me exactly what I need in my circumstances. My only little complain would be that they’re waiting list for installation was more then two months long but eventually I am happy I waited as they provide great service. Highly recommended!

Great customer focused company

Sales and quoting:
Ultimately RenewCo had the cheapest price (for the grade of system) but after comparing other quoted systems decided that the Sigenergy and REC panels was the best system within my budget. RenewCo also offered options for next tier down panels.
RenewCo had quoted when both state and federal battery rebates were in place, but then the state (NSW) removed their rebate, Renewco adjusted their offer to lessen (share) the impact of the reduced rebates by upgrading the battery storage.

Installation:
Worked with me around other factors.
RenewCo removed the old PV system, then my solar hot system failed and I replace with a heat pump, Renewco also removed the old hot water panels. And then worked around my roofer doing a roof clean and restoration.
Installation crew showed up on time, polite and efficient, system was online by mid afternoon (1 day install).

Customer service:
Everyone I dealt with was friendly and professional, answered all my questions.

Great sales and quoting process and seamless installation

RenewCo Solar was very helpful in tailoring a solar and battery solution which met my energy savings goals. We worked together to develop something that I was very happy with.

They kept me thoroughly informed throughout the whole process, and the installation was completed within the day with no issues.

Customer service was also fantastic, offering helpful answers to all my questions.

Would highly recommend them to anyone wanting a tailored solar and/or battery solution, and a great quality installation!

New Install of Battery & Solar

* Good detail on quote
* Pricing was within expected range for a good installer
* Whatsapp group for questions and answers before, during and after installation
* Big group of trades showed up on install day on time and kept going until all was done. Site wa cleaned and no parts were left behind. It was a long day (nearly 12 hours beginning to end).
* System was explained after install and final compliance signatures were only done at the very end.
* Electrical board changes were walked through including no master cut offs and individual isolation switches. All installation looked professional.

Quality installation and service

The quoting process was easy. I had a rep attend my property to see the site and explain to me how RenewCo Solar system work and the various options. I was impressed with his knowledge. I obtained other quotes but went with RenewCo mainly because they instilled more confidence in me.

The installation was excellent. The installers were polite, pleasant and on time. They left the site tidy and explained everything to me.

I am impressed with the app that allows me to monitor my system, and with the after installation service (that I haven't yet needed to use).

Great team who went above and beyond

RenewCo Solar were the only people who actually came to site for the quote and helped me understand what was and wasn't possible. They were super proactive in their communication, especially when the rebate amounts changed due to the NSW government rebate changing, and nothing was too much trouble. The team who installed the battery were fast and respectful and a pleasure to have at our home. So far so good!

Fantastic Installer

RenewCo Solar provided a clear booking process, arrived on time, and did an excellent install and clean up, answering all my questions on the way. Great communications throughout the process, especially navigating the abrupt cancellation of the NSW rebate program.

Sigenstor Battery Installation

Pre-Sale with Rhys was great, factual and knowledgeable. Of four quotes, only two visited our site, Rhys being one.

They overcame the hiccup of NSW pulling their rebate with an innovative offer.
Lead time was ~ 6 weeks in a peak period (June - July). Installation was scheduled early and didn't change.

The installation crew of 3 arrived on time on the scheduled date.
They were done and cleaned up in 3 hours.
The installation is professional and neat.
Everything works as it should.

Great service and install

We're very happy with the whole process provided by RenewCo, from first on-site contact with the battery consultant, to the support staff, and the expert installers on the day. The battery is performing very well and we can only recommend this system to others. Great team and a high quality product. Would use the team here again.

The team at Renewco : Best Value, Best Service

We wanted the best possible system installed with the maximum residential capture and storage. Of the 4 companies we reviewed, we went with Renewco. From the beginning they were the most professional. They listened to our requirements, designed the system to our specifications and installed the system and batteries on time and without any issues.

Not the cheapest, nor the most expensive. But, for our needs, definitely the best value and the most professional. Great service and attention to detail.

We’re very happy with our system and happy to recommend the team at Renewco.

Beautiful Battery install

The sales person came out to inspect our property, he looked at what we had already set up on the roof, checked the power bills and usage.
Kurt made some recommendations and said that he would email me the quote once he puts a design together. the NSW government pulled out of the rebates and the company still helped me out with honoring the system quoted.

Great job throughout process from start to finish.

Was a pleasure dealing with Rhys with quoting and sales process.

On the day, the install team arrived on time and we first discussed the full details of our install including materials used and how all the cabling would be run.

Whole install took a good 8 hours in total and nearly an hour of cleaning up and going through things.

Would recommend RenewCo Solar for competitively priced solar/battery supply & installs, coupled with decent customer support.

Excellent experience from beginning to end.

RenewCo Solar delivered what they promised in every way. Proposed installation was explained clearly with prompt follow up of quote.
Installation went smoothly with the friendly and professional team completing the job in good time with all waste removed.
Especially value the excellent post installation service that is ongoing at no extra cost. A deal breaker for me.
