Common questions about solar installers in Penrith.

Who are the best solar installers in Penrith?

As of October 2026, the 3 highest-ranked solar installers in Penrith, NSW on the Starworks directory are Clean Earth Solar (5.0 stars from 249 Google reviews), E-Smart Solar Pty Ltd (5.0 stars from 210 Google reviews) and MKG Electrical Pty Ltd (5.0 stars from 163 Google reviews). Every figure here is computed from Google review data that Starworks collects for solar installers in Penrith, NSW, recalculated when this page rebuilds. Placement on this list cannot be bought.

How many solar installers does Starworks rank in Penrith?

Starworks ranks 37 solar installers in Penrith, NSW, holding 4,317 Google reviews between them. Across the 37 the median rating is 5.0 stars from a median of 46 reviews. Of the 37, 34 are rated 4.5 or better and 11 have passed 100 reviews. The most-reviewed carries 997 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 Penrith?

The median Google rating across the 37 solar installers Starworks ranks in Penrith, NSW is 5.0 stars, and 34 of them sit at 4.5 or above. A rating at or near that median is ordinary for solar installers in Penrith, 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 Penrith have?

The median solar installer Starworks ranks in Penrith, NSW carries 46 Google reviews, and 11 of the 37 solar installers have passed 100. The most-reviewed of them carries 997.

How does Starworks rank solar installers in Penrith?

Starworks gives every solar installer in Penrith, 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 Penrith 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 Penrith, 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 37 distinct solar installers in Penrith, NSW rather than a longer list of repeats.

How often is this list of solar installers in Penrith updated?

This ranking of solar installers in Penrith, 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 Penrith?

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 Penrith, NSW carries 46 Google reviews at 5.0 stars.
