Sun Spark Energy
Raj handles sales to post-install monitoring — customers name him and installer Niki separately for doing their jobs well.
That kind of after-sales involvement is worth confirming at the quoting stage, particularly for battery installs where grid connection timing can cause delays. Installer Niki Tsounis is named repeatedly for workmanship quality and site cleanliness, including one detailed account where an accidental crack to a polycarbonate roof sheet was repaired and replaced at no cost within two days — the kind of accountability that's meaningful in a trade context. This is a young company with about a year of trading behind it, so the review sample reflects that early-stage period; homeowners doing due diligence should ask directly about CEC accreditation and warranty-claim processes, since those are harder to verify from reviews alone.

About Sun Spark Energy
Sun Spark Energy is led by Raj Patel, who handles sales consultations, system design, and ongoing customer support — with reviewers noting he monitors system performance after installation and even contacts electricity retailers on behalf of customers to arrange meter updates. The installation side is run by Nikiforos (Niki) Tsounis, a licensed electrician whose work is consistently described as neat and efficient, with projects regularly completed within a single day or to the agreed schedule. The business works across solar-only systems, battery-only retrofits, and combined solar-and-battery installs, with product choices leaning toward Jinko Solar panels paired with Fox ESS, Sofar, or Sigenergy battery storage — all brand names customers are specifically naming in their reviews. Jobs have ranged from modest battery additions up to 42kWh battery installs and 15kW solar arrays, suggesting they're comfortable with larger residential energy projects, not just entry-level systems. Reviews mention handling of permits, paperwork, Certificate of Electrical Compliance, and a monitoring app that gives real-time production data — useful for homeowners who want a fully managed install rather than just someone to bolt panels on the roof. As a GST-registered company active for roughly a year, they're a newer operator but with a focused, two-person core team that appears to be taking on a manageable volume of work rather than scaling too fast.
Best for: combined solar-and-battery installs where you want one contact managing the whole process, battery retrofits onto existing solar systems, larger residential energy storage projects, and homeowners who want post-installation monitoring support from the person who sold them the system.

What brands of solar panels and batteries does Sun Spark Energy install?+
Customers most often mention Jinko Solar panels paired with Fox ESS, Sofar, or Sigenergy battery storage systems. Reviews reference system sizes ranging from standard residential solar arrays up to 13.2kW solar with 42kWh battery storage. It's worth asking Raj at the quoting stage whether these are the only brands offered or whether alternatives are available for your specific setup.
Does Sun Spark Energy manage the paperwork and grid connection process?+
Reviews suggest yes — multiple customers specifically mention that Raj handled permits, the Certificate of Electrical Compliance (eCoC), and contacted their electricity retailer to arrange meter updates after installation. One reviewer called it 'a hassle-free experience' because all of this was managed without the homeowner needing to chase it. Confirm the scope of this service at your consultation since it can vary depending on your network distributor.
How long does a typical installation take with Sun Spark Energy?+
Several reviewers mention the installation being completed within a single day by Niki (Nikiforos) Tsounis, the lead installer. One customer had a 15kW solar system with 30kWh battery installed within three weeks of the initial site visit, while another noted their solar and battery was installed within a week of receiving a quote. Timelines can vary based on system size and grid connection requirements, so ask for an expected schedule during the quoting process.
What happens if something goes wrong during or after the installation?+
One detailed review describes an accidental crack to a polycarbonate roof sheet during removal of an old solar system — the team sealed it immediately with silicone and replaced the sheet within two days at no cost. Reviews also note that Raj continues to monitor system performance after installation and is responsive to questions. Since the business is approximately one year old, it's worth asking specifically about product warranties and how warranty claims are handled if a panel or battery component fails.
Is Sun Spark Energy suitable for larger or more complex residential solar projects?+
Reviews mention jobs including a 42kWh battery install, a 15kW solar array with 30kWh battery storage, and a project involving removal of an old 10kW system before installing a new 13.2kW setup with a full battery. One reviewer notes the team managed a full switchboard with no spare space for new switches without issue. These aren't entry-level installs, so if you have a larger or more technically involved project, the team appears to have handled comparable scope before.
