Why we exist

Plenty of people have had a bad run with solar.

Before starting Sunsave, Lachlan installed systems for other companies and saw how often homes ended up with the wrong one: oversized, oversold, and no one to call afterwards. Sunsave is set up to work differently.

What you've probably experienced

  • Sells to anyone — doesn't care what happens after the install
  • Inflated, absolute savings promises
  • Salespeople who've never touched the hardware
  • Emails a cheap number, never shows up in person
  • Oversized systems and hidden costs
  • Cheap gear that fails when the warranty matters most

How Sunsave works instead

  • We ask a lot of detailed questions and design for your actual usage and goals
  • Estimates that account for winter, not just summer
  • Follow-up after the install to make sure it's working as planned
  • The owner turns up at your house, in person
  • Proper sizing and transparent pricing — we only promise what we can deliver
  • Sigenergy and GoodWe hardware, with ESY Sunhome for budget systems

How it works

Three steps.

A quick call

One of our team gives you a ring and asks a bit more about your bills, your roof and what you're after — to check a system makes sense for you before Lachlan visits.

An in-home consult

Lachlan visits to go through your bills, roof and switchboard, your options and your questions. We ask that all homeowners are there, so everyone hears the same thing and can ask their own questions.

A design built for you

A tailored system with transparent pricing. If your existing setup just needs fixing, that's what we'll tell you instead.

What we stand for

What customers say about how we work

He didn't try to sell me something I didn't need.

Russell got in touch about a bigger system. What he actually needed was his existing one set up right — so that's what we sorted, and we wouldn't take payment for it.

"Super trustworthy company! I enquired with Sunsave as my bills were quite high, wanting to size up additional solar and battery to help bring them down. Lachlan came around to do an assessment, but when he looked over my existing solar and battery system (6.6kW solar and 20kWh battery), he suspected something wasn't right based on my bill. He sat down with me, looked over the existing system, and found the exact issue — the previous installers hadn't programmed the settings correctly! Lachlan gave me a list of things to ask the other installers to fix. I came in expecting to be sold a whole new system, but instead he helped me fix my existing one. I offered to pay him for his time and help, but he wouldn't take anything — he just asked for a review. Based on my experience with Lachlan, he didn't try to sell me something I didn't need. Very ethical. I highly recommend Sunsave."

The owner came to my house himself — before and after the install.

"I found Sunsave Co on Facebook from one of their ads, and I had someone ring me and organise Lachlan to come out. He was actually the owner of the business, and he came to my house, had a look at what's involved and explained how it works and the cost of the system. I chose to go with him to support a young Aussie business. A couple of weeks later the install was organised. It took about 4 hours and the installer's name was Germaine - he did a really good job. I had my electrician mate come out and he said it was bloody good work. Lachlan came out about a week later to my house and explained to me how the whole system worked now that it had been installed, and showed me the app. Overall very happy with Sunsave, would recommend to my friends and family."

Our latest electricity bill is actually $0.

"We recently installed a solar battery with Sun Save, and the whole experience from sales to installation was very smooth. The team was very helpful, explained everything clearly, and the installer was very professional. Our home has limited roof space and some shading from trees, so our solar panel system is not very large. Before installing the battery, we could only reduce our electricity bill by around 35–40%, and the solar export was not enough to cover the daily supply charge. After installing the battery and switching to Globird Energy, the system works really well for our situation. Our latest electricity bill is actually $0, and we even received a credit on the account. We are now fully electric and no longer use gas, so we have no electricity bill and no gas bill at all, which is amazing. We can also use multiple appliances at night without worrying about electricity costs. Overall, we are very happy with Sun Save and would highly recommend them to anyone considering a solar battery system."

The power went out overnight, and the battery still had 53% in the morning.

"Lachlan goes above and beyond to get it right, even down to sorting out my existing LG battery issues. The outage protection kicked in last night and I only knew because of text messages from Ausnet. My new Fox ESS 32kwh battery supplied and installed by Sunsave still had 53% this morning. Perfect system, I love it."

"We were months trying to find a provider who would show up for an appt. Lachlan from Sun Save came, set us up, prompt, efficient service, and excellent post sales followup. For 2 older computer-illiterate people, Glenda in the office was very helpful, and patient ! Thanks all !"

"I highly recommend SunSave for your battery and solar installs. Lachlan was very thorough in explaining options. I made several enquiries and obtained quotes from 2 other providers, but I was super impressed with Lachlan's attention to detail and ability to find a solution that worked for me. Communication was excellent - installers turned up when they said they would and confirmed everything by phone and SMS. I was most surprised that the anticipated savings from the model have actually been realised and instead of a $120-150 per month electricity bill (before battery), I'm now getting a bill in credit of around $30-35 per month. Super impressed with the care, attention and follow up from SunSave."

"Lachlan at SunSave was amazing! Very informative , professional and he explained the whole process of the solar panel installation from start to finish. His crew were efficient, experienced and dependable. I cannot praise them enough for a job well done. I would highly recommend their work and the after sales service was beyond excellent. If only other trades could be this exceptional . I’m More than happy to provide a genuine reference if required."

"Sunsave have recently replaced our very old, small battery system with a 32 kWh battery and a 5 kW inverter. From the initial contact with Riley (sales) to the installation and final inspection the whole process went smoothly. Lachlan was involved in helping us make choices and was happy to do an on-site follow-up visit to explain a few technical issues. Our previous billing company reduced the feed in tariff (FIT) to zero so the financial benefit of solar panels was much diminished. We changed our billing company to Flowpower which has a ‘ happy hour ‘ where they take power back to the grid from our 32kWh battery between 5.30 - 7.30 PM and pay us for it. Lachlan set this up for us. Our most recent bill has a $78 FIT credit. Beautiful! We are happy to recommend Sunsave to anyone considering installing a solar battery system."

"I'm very happy to recommend SunSave Co. We left it late to get a battery installed before the gov rebate drops in May so I was scrambling. I was receiving quotes from multiple websites and companies with varying degrees of prices, promises and options. I saw SunSave Co on Instagram and thought I'd try them too. Lachlan from the ad was the person who arrived to do a site inspection and had great ideas and knowledge. He took the time to look at our bills, house dynamics and goals. He explained our options clearly and helped us make a plan that stood out against the other quotes. SunSave Co are a young and impressive group who I'm happy to support."

"Lachlan was great in outlining the actual requirements, how to maximise the system (Solar and battery) and was to his word on all discussions before during and after the install. Very happy with the system, the service the responsiveness. Have already recommended to other family members."

Worth knowing

Three things worth knowing before you buy

Winter output is real

Solar produces a lot less in a Victorian winter than in January, so we size the system and estimate savings for the whole year.

Standard solar turns off in a blackout

It's a safety requirement. If you want backup power, the system needs to be designed for it from the start, with a backup-capable battery and the right circuits chosen.

The battery rebate is tiered, not flat

Since May 2026 most of the federal discount sits on the first 14 kWh of usable capacity, and it tapers after that, so the dollar figure depends on the battery size. See how it works.
