Common questions about solar installers in Newcastle.
Who are the best solar installers in Newcastle?
As of October 2026, the 3 highest-ranked solar installers in Newcastle, NSW on the Starworks directory are Hunter Solar Solutions (5.0 stars from 341 Google reviews), EcoKleenSolar Newcastle (4.9 stars from 927 Google reviews) and Solahart Newcastle, Hunter Valley, Port Stephens and Lake Macquarie (4.8 stars from 842 Google reviews). Every figure here is computed from Google review data that Starworks collects for solar installers in Newcastle, NSW, recalculated when this page rebuilds. Placement on this list cannot be bought.
How many solar installers does Starworks rank in Newcastle?
Starworks ranks 74 solar installers in Newcastle, NSW, holding 6,214 Google reviews between them. Across the 74 the median rating is 4.9 stars from a median of 35 reviews. Of the 74, 63 are rated 4.5 or better and 18 have passed 100 reviews. The most-reviewed carries 927 reviews, more than the top-ranked solar installer holds, which is why rating alone does not set the order.
What star rating should I expect from a good solar installer in Newcastle?
The median Google rating across the 74 solar installers Starworks ranks in Newcastle, NSW is 4.9 stars, and 63 of them sit at 4.5 or above. A rating at or near that median is ordinary for solar installers in Newcastle, NSW rather than a warning sign on its own, and a rating well above it only means much when enough reviews stand behind it.
How many Google reviews does an established solar installer in Newcastle have?
The median solar installer Starworks ranks in Newcastle, NSW carries 35 Google reviews, and 18 of the 74 solar installers have passed 100. The most-reviewed of them carries 927.
How does Starworks rank solar installers in Newcastle?
Starworks gives every solar installer in Newcastle, NSW a reputation score out of 100 from three things: its Google star rating (up to 47 points), how many reviews back that rating (up to 35), and whether customers can reach it by website and phone number (up to 18). Review volume is the one part that can subtract: below 15 reviews it costs points, because a near-empty review record gives a stranger very little to go on. No score falls below 0 and placement cannot be bought. The score measures the strength of a business's public review record rather than the quality of its work, so it is worth reading the reviews as well, and every listing links to them on Google.
Why does a solar installer in Newcastle with all 5-star reviews score lower than one with a lower rating?
Because review volume counts as well as rating, and below 15 reviews it counts against you. Five perfect reviews are encouraging but thin evidence; three hundred reviews averaging 4.7 tell a stranger far more about what to expect on the day. That is a judgement about how much proof exists, not about the quality of the work, and a newer solar installer with a handful of excellent reviews may still be the right choice in Newcastle, NSW. The star rating and review count sit next to every score so you can weigh both yourself.
Why does the same solar installer not appear several times on this list?
Some businesses run more than one Google listing, often one per suburb they service. Those are the same company, so Starworks groups them and shows the business once, using the listing with the strongest review record. That is why this page opens with 50 distinct solar installers in Newcastle, NSW rather than a longer list of repeats.
How often is this list of solar installers in Newcastle updated?
This ranking of solar installers in Newcastle, NSW rebuilds on a 30-day cycle and prints the date of its last rebuild above the list, which for the current version is October 2026. Ratings and review counts are re-read from Google over time rather than on a fixed schedule, so an individual figure here can be older than the rebuild date.
How can I improve my solar installer business ranking in Newcastle?
Collect genuine customer reviews consistently, and keep a working website and phone number on your Google listing, because those are the three inputs the score reads. There is no placement to buy on this page. For scale: the median solar installer Starworks ranks in Newcastle, NSW carries 35 Google reviews at 4.9 stars.
