Spider Solar & Electrical
Brandon's crew drove an hour on a Friday night for a post-install fix — and refused to charge for it.
The sample reviews mention systems ranging from 6.63kW residential installs up to 30kW commercial-scale setups with 48kW batteries on three-phase connections, which suggests they're comfortable with complexity that smaller operators might decline. Before hiring, it's worth asking them specifically about your inverter brand preference and whether your property requires a grid connection application, since three-phase and large battery installs often involve additional paperwork and network approval timelines that can affect your go-live date.

About Spider Solar & Electrical
Brandon leads the installation crews at Spider Solar & Electrical, and the reviews paint a clear picture of someone who treats complex, large-scale solar and battery jobs as his speciality — think 30kW Sigenergy systems across three-storey roofs, 48kW battery banks, and three-phase setups with emergency backup circuits. Ben or Brendan (reviewers use both names, likely the same person) handles system design consultations, walking homeowners through multiple configuration options with patience rather than pushing a single package. What sets the operation apart is the cabling discipline — multiple customers specifically call out how cables are routed and concealed, which matters when your inverter is in a garage and your panels are three floors up. The business is GST-registered and structured as a company, and their Google categories include general electrical work, so battery storage integration, inverter selection, and grid-tied system design appear to be genuine competencies rather than an add-on service. After-hours responsiveness also comes up unprompted: one customer describes Brandon driving an hour on a Friday evening at 7pm to fix a hot water thermostat issue at no charge — the kind of detail a fussy tradie would notice and specifically remember.
Best for: large or technically complex solar-plus-battery installations, three-phase system upgrades, homeowners wanting a hands-on installation lead throughout the project, and EV charging integration as part of a broader solar setup.

What size solar and battery systems does Spider Solar & Electrical typically install?+
Based on the reviews available, the team handles a wide range, from a 6.63kW residential system up to a 30kW array with a 48kW battery bank installed across a three-storey roof. They've worked with Jinko panels, Fox ESS and Sigenergy inverters, and three-phase connections with emergency backup circuits. This suggests they're set up for jobs that go well beyond a standard entry-level install. If you have a complex roof or a large energy requirement, they appear to be worth getting a quote from.
Who will I deal with at Spider Solar — is there one contact person or a team?+
Brandon appears to lead the installation crews and project management, and customers mention him as the main point of contact from quoting through to after-install support. Ben (also referred to as Brendan in some reviews — likely the same person) is mentioned for pre-sale system design consultations, where he's praised for working through multiple configuration options patiently. Expect the same people across your project rather than a rotating roster of subcontractors, based on what reviewers describe.
Do they offer after-hours or emergency support once a system is installed?+
One review specifically describes Brandon driving roughly an hour to a customer's home on a Friday night at 7pm after a hot water thermostat issue was linked to a new Sigenergy installation — and refusing payment for the visit. This is an isolated account from the small sample we reviewed, so it's not a guaranteed policy, but it suggests a hands-on approach to post-install issues. It's worth asking them directly what their after-installation support process looks like before you sign a contract.
How does Spider Solar's pricing compare to other solar installers?+
Two customers in the reviews we reviewed noted that Spider Solar came in more competitively priced than other quotes they received for the same system and brands. One compared pricing against other companies quoting for an identical Jinko and Sigenergy combination. That said, with only a small review sample to go on, it's hard to say whether this is a consistent pattern or reflected specific job circumstances. Getting at least two or three competing quotes for your system size is always worthwhile, but the pricing feedback from available reviews is positive.
Does Spider Solar & Electrical cover areas outside Penrith?+
At least one review describes Brandon travelling approximately an hour from the business location for an after-install support visit, which suggests they do work beyond the immediate Penrith area. The reviews don't specify exact service boundaries, so if you're outside the greater Penrith region, confirm directly with them whether your location is serviceable and whether travel charges apply for your install or any follow-up visits.
