OffGrid WA
Three reviewers describe Mark running through multiple system configurations until the design matched their exact energy goals.
The standout pattern is that Mark handles the technical design consultation while Jason manages the client relationship, and the combination seems to work: reviewers describe feeling genuinely informed rather than sold to, and the post-install results match what was promised. Thirteen-plus years of operation and GST registration give this business the structural credentials that matter for warranty and rebate paperwork, but given the small sample reviewed here, it's worth asking them directly about their Clean Energy Council accreditation status and which inverter and battery brands they currently supply.

About OffGrid WA
Jason leads the OffGrid WA team and appears throughout reviews as the central point of contact for quoting and communication, while Mark is consistently praised for deep technical consultation — specifically his ability to run through multiple system configurations on the phone until a client's exact goals are mapped to the right solution. The business handles significant residential solar and battery installs, with multiple reviewers describing large-scale systems: 45-panel, 3-phase setups with 32 kWh battery banks, and 22 kW arrays paired with 40 kWh Sigenergy batteries configured for full off-grid backup. Where many installers treat cabling as an afterthought, the OffGrid WA crew has drawn specific praise for concealing conduit inside wall cavities and routing cables invisibly across complex rooflines dotted with flues and skylights — a detail that matters on premium residential properties. The office team, Christy and Trish, handle the administrative and communication side in a way that customers explicitly call out, which is uncommon enough to be worth noting. For homeowners overwhelmed by conflicting solar information online, reviewers describe the consultation process as genuinely clarifying — not a sales pitch, but a structured walkthrough of what a system needs to do before any equipment is specified. The business has been operating for over 13 years and is a registered GST company, which matters for warranty claims and Clean Energy Council compliance paperwork.
Best for: large residential solar and battery installs requiring off-grid backup capability, homeowners with complex rooflines or aesthetic requirements for concealed cabling, and customers who want detailed technical consultation before committing to a system design.

What size solar and battery systems does OffGrid WA typically install?+
Based on the reviews available, OffGrid WA handles large residential installs — examples include a 45-panel system with 32 kWh of battery storage and a 22 kW array paired with a 40 kWh Sigenergy battery. These aren't starter systems; the business appears to focus on homeowners who want meaningful energy independence rather than modest bill reduction. If you have a smaller or simpler requirement, it's worth confirming upfront whether that's within their typical scope. Most reviewers mention calling Mark or Jason directly to discuss options before committing to a quote.
How long does it take from first contact to installation being completed?+
One detailed review describes the full timeline: quote request submitted on 8 January, first call from Mark on the 12th, engineer site visit on the 20th, and installation completed on the 28th-29th — roughly three weeks start to finish for a large system. That reviewer noted they were fortunate with timing given industry demand around changing battery rebates. This pace appears to be the norm rather than an exception based on other reviewers describing the process as seamless, but timelines can vary with system complexity and scheduling. Confirm current lead times when you request your quote.
Who will I be dealing with during the quoting and installation process?+
Reviews name the team fairly specifically. Jason is consistently mentioned as the primary client contact and quote lead, while Mark handles the in-depth technical consultation — running through system options over the phone until the design matches your goals. Christy and Trish in the office manage scheduling and communication, and reviewers call them out by name as part of why the process felt smooth. On-site, Tyson and Mason are mentioned alongside the broader install crew. It reads as a structured team rather than a single operator doing everything.
Can OffGrid WA design a system that works during power outages?+
Yes — one reviewer specifically requested full off-grid backup capability due to frequent local power outages, and Mark offered multiple system configurations to meet that goal, ultimately delivering a setup the homeowner says has made every subsequent outage invisible. The system was deliberately oversized to allow for future increased energy demand. If outage resilience is your primary reason for going solar-plus-battery, this appears to be a use case the team designs for explicitly rather than treating as an add-on. Ask them about battery backup transfer speed and whether the system covers your whole home or just selected circuits.
What do customers say about OffGrid WA's pricing?+
Multiple reviewers describe the pricing as competitive or 'amazing,' particularly given the scale of the systems installed. One reviewer praised the value explicitly after a large residential install, and another noted the quote was competitive before proceeding with a 22 kW system. No reviewer raised concerns about pricing in the sample available. That said, only 5 reviews were analysed here, so this reflects a small snapshot — it's worth getting at least one comparison quote for a system of this size to benchmark the figure you receive.
