National Grid Support
Named reps Dave and Sam repeatedly praised for sizing systems around your actual bills, not a standard package.
A meaningful cluster of reviews (roughly 6 out of 36) describes a period of silence after sign-up: emails and calls going unanswered for weeks, with scheduling updates only appearing after customers escalated or threatened to cancel. Post-install warranty responsiveness draws similar criticism in 4 reviews, worth keeping in mind given the subcontractor model means some issues can fall between NGSS and its installation partners. The trajectory in the sample is cautiously encouraging — more recent reviews skew higher than earlier ones — but the gap is wide enough that confirming your project manager's contact details and expected communication schedule before paying any deposit is practical advice, not just precaution.

About National Grid Support
NGSS specialises in residential solar PV system installation and battery storage, with a consulting approach that starts by analysing actual household energy bills before sizing a system — something multiple customers specifically called out as making them feel confident rather than oversold. Sales rep Dave is mentioned by name across several reviews for being unhurried, thorough with paperwork, and helpful navigating government rebate documentation, while Sam is praised for connecting the conversation to customers' broader sustainability goals rather than leading with price. The installation crews — who operate as subcontractors in at least some cases — consistently draw praise for punctuality, careful handling of tiled roofs, and walking customers through the inverter before they leave. With roughly 26 years of operating history and GST registration as a company entity, NGSS sits closer to the structured end of the solar installer market rather than the sole-trader end, which matters for warranty continuity. Where the experience has gone well, customers describe a seamless handoff from sales to install to grid connection — but the subcontractor model has created friction in at least a few cases where post-install issues landed in a gap between NGSS and its contractors. They're best approached by homeowners who want a consultative first meeting and are comfortable following up proactively on scheduling.
Best for: homeowners wanting a detailed in-home energy assessment before committing to a system size, first-time solar buyers who need help with government rebate paperwork, and households adding battery storage alongside a new solar install.

What does the consultation process with NGSS look like before installation?+
Based on multiple reviews, NGSS sends a sales consultant to your home for a session that typically runs around 90 minutes. Reps Dave and Sam are mentioned by name across reviews for going through your actual electricity bills to size the right system rather than defaulting to a standard package. Customers describe the process as informative and unhurried, with technology options, battery add-ons, and government rebate eligibility all covered in the one visit. If you're after a consultative approach rather than a quick quote-and-go, this suits that style.
How long does installation typically take, and what's the on-site experience like?+
Reviews consistently describe installations completing in a single day — one customer noted around six hours from arrival to walkthrough. Crews are described as punctual, careful on tiled roofs, and tidy with cleanup. Standard practice appears to be a handover at the end where the installer walks you through the inverter and monitoring app before leaving. Note that NGSS uses subcontractors for at least some installations, so the crew on the day may not be direct NGSS employees.
What do customers say about communication between signing up and getting an install date?+
This is the area where reviews diverge most sharply. Several customers report smooth, proactive updates through to installation completion. However, around six reviews describe a frustrating silence after the deposit was paid — weeks passing without a scheduled date despite repeated emails and calls. The pattern appears often enough that it's worth getting a named point of contact and an expected scheduling timeline in writing before committing. Recent reviews trend more positively on this, but the inconsistency is worth being aware of.
Does NGSS handle warranty and after-sales issues directly?+
Reviews suggest this is mixed. Some customers report smooth after-sales follow-up, while others describe difficulty reaching anyone when issues arose post-installation — including one case involving a roof leak traced to improperly sealed panel footings, and several cases of unanswered warranty service calls. Because NGSS uses external contractors for installation, there can be ambiguity about who is responsible when problems surface. It's worth asking NGSS directly how warranty claims are handled and who the point of contact is if the original installer needs to return.
Does NGSS operate in Tasmania, and what areas do they cover?+
NGSS is listed as based in Derwent Park, TAS, and at least one review explicitly names Bagdad, Tasmania as a completed job location. Reviews also reference work done in Victoria, suggesting they may operate across multiple states. The platform lists them under Derwent Park, so for Tasmanian homeowners they appear to be a locally relevant option — but it's worth confirming your specific suburb is within their current service area when you make contact.
