Who are the best solar installers in Prospect?
As of October 2026, the 3 highest-ranked solar installers in Prospect, SA on the Starworks directory are United Solar and Electrical (5.0 stars from 33 Google reviews), Off-Grid Energy Australia (4.7 stars from 61 Google reviews) and SunSolar Energy Pty Ltd - Solar Installation Company in Walkerville (5.0 stars from 2 Google reviews). Every figure here is computed from Google review data that Starworks collects for solar installers in Prospect, SA, recalculated when this page rebuilds. Placement on this list cannot be bought.
How many solar installers does Starworks rank in Prospect?
Starworks ranks 7 solar installers in Prospect, SA, holding 152 Google reviews between them. Across the 7 the median rating is 4.9 stars from a median of 11 reviews. Of the 7, all are rated 4.5 or better. The most-reviewed carries 61 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 Prospect?
The median Google rating across the 7 solar installers Starworks ranks in Prospect, SA is 4.9 stars, and all of them sit at 4.5 or above. A rating at or near that median is ordinary for solar installers in Prospect, SA 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 Prospect have?
The median solar installer Starworks ranks in Prospect, SA carries 11 Google reviews. The most-reviewed of them carries 61.
How does Starworks rank solar installers in Prospect?
Starworks gives every solar installer in Prospect, SA 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 Prospect 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 Prospect, SA. 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 7 distinct solar installers in Prospect, SA rather than a longer list of repeats.
How often is this list of solar installers in Prospect updated?
This ranking of solar installers in Prospect, SA 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 Prospect?
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 Prospect, SA carries 11 Google reviews at 4.9 stars.
