BJ Energy
Ben fields calls from customers by name 18 months after installation — a level of follow-through that runs through every review in their history.
That's rare in solar installation, where the business model often moves on once the panels are up. The trajectory is completely stable — no dip in recent reviews — and the work spans a wide range, from 6kW residential systems to a 32kWh battery setup, gas-to-electric conversions, and warranty support through SolarEdge's own processes. If you're comparing quotes, it's worth asking Ben directly about system sizing for your specific roof and usage profile — several reviewers say that conversation alone was what differentiated him from other installers they approached.

About BJ Energy
Ben, the owner of BJ Energy, runs a residential solar and electrical company where he stays personally involved from the first phone call through to post-installation support — multiple customers mention calling him months or even years later and having him pick up by name. The business handles full solar system design and installation (including SolarEdge, Tesla Powerwall, and large-scale battery configurations up to 32kWh), inverter replacements, switchboard upgrades, and the full range of residential electrical work like downlights, ceiling fans, and data cabling. What sets Ben apart in the quoting process is a genuine willingness to walk homeowners through the complexity of solar rather than just pushing a system — reviewers specifically flag his patience with questions and his ability to explain technical options clearly without jargon. On installation day, the crew arrives as a cohesive team; customers note they work efficiently, clean up thoroughly, and take care of aesthetic details like cable routing without being asked. Alyssa handles initial enquiries and quoting coordination on the admin side, and the team also trains apprentices on-site — something one customer specifically called out as a mark of a business investing in quality beyond the current job. BJ Energy is particularly well-suited to homeowners taking on complex or whole-home electrification projects — gas-to-electric conversions, major renovations, or multi-component solar-plus-battery setups — as well as people whose previous solar installer has gone out of business and need someone to pick up ongoing support.
Best for: whole-home solar-plus-battery installations requiring custom design advice, homeowners switching from gas to electric appliances, customers needing ongoing post-installation support, and anyone whose previous solar installer has closed and left them without coverage.

Does BJ Energy use subcontractors or their own installation team?+
BJ Energy uses their own employed install team, not subcontractors — this was explicitly confirmed by the office (Alyssa) to a customer who asked directly before signing, and that same customer noted the crew worked like a close-knit group on the day. Reviewers consistently describe the same team members appearing across different jobs, which supports this. If this matters to you, it's worth confirming again at time of quote since staffing can change, but every review in their history points to an in-house crew.
What solar systems does BJ Energy typically install?+
The systems most frequently mentioned across reviews are SolarEdge inverter-based setups, Tesla Powerwall batteries, and large residential configurations ranging from 6kW up to 13.3kW with batteries up to 32kWh. Ben has also installed heat pump hot water systems integrated with solar monitoring, and handles add-ons like switchboard upgrades and aerial relocations in the same job. Customers note he recommends systems based on actual usage and circumstances rather than defaulting to a single product.
Can BJ Energy help if my current solar system has a fault or my original installer has gone under?+
Yes — this is something BJ Energy has done for multiple customers. Reviews mention Ben stepping in to diagnose faults, navigate SolarEdge warranty processes, and replace failed inverters for customers whose original installer was no longer operating. One customer described Ben resolving an emergency power outage issue the same evening after explaining the urgency. If you're in this situation, reviewers suggest being upfront about the timeline — Ben has responded quickly when customers explained the disruption to their daily life.
What do customers say about pricing?+
Pricing feedback across the 43 reviews is almost entirely positive — customers describe quotes as 'reasonable' and 'right around the figure I had in mind,' and several mention the value over time (one customer references a payback period of around 6-7 years). No reviewer raised a concern about overcharging or unexpected costs. Specific dollar figures aren't mentioned in the reviews, so it's worth getting a written quote for your system size — Ben is noted to be responsive and available by phone during the quoting process.
Does Ben stay involved after the installation is complete?+
This is one of the most consistently mentioned points across the review history: Ben remains personally reachable well after the job is done. One customer mentions calling him 18 months post-installation and being recognised by name. Another describes him helping navigate an ongoing SolarEdge support process that required repeated follow-up. If long-term support matters to you — especially for a solar-and-battery system where questions come up over months and years — this is a genuine differentiator based on what customers report.
