Going about it this way meant smaller companies with fewer reviews had a decent chance against their bigger rivals. All SA installer listings were analysed during this process, not just those installers who are part of the SolarQuotes network.<\/p>\n<h2>First Place &#8211;\u00a0 Goliath Solar &amp; Electrical<\/h2>\n<p><a href=\"https:\/\/goliathelectrical.com.au\/\">Goliath Solar &amp; Electrical<\/a> have been installing solar systems in Adelaide and across South Australia since 2012. In addition to solar panels, the company also supplies and installs battery systems and EV chargers.<\/p>\n<p>Founder David Stevens, an electrician trained by his uncle, says the trigger for getting into solar installation was a dislike of fly-by-night firms and the way some industry giants were treating their customers; supplying little pre-install information with no assistance after the system was installed.<\/p>\n<p>The company&#8217;s solar installers are employees \u2014not sub-contractors \u2014 who have worked alongside David Stevens, learning the &#8220;Goliath Solar &amp; Electrical way&#8221;. The firm&#8217;s solar consultants come from customer service backgrounds and have been technically trained in the solar industry, and pushy sales techniques are a no-no.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-94871\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2025\/09\/goliath-solar-installation.jpg\" alt=\"Example solar installation - Goliath Solar &amp; Electrical\" width=\"900\" height=\"561\" srcset=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2025\/09\/goliath-solar-installation.jpg 900w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2025\/09\/goliath-solar-installation-300x187.jpg 300w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2025\/09\/goliath-solar-installation-768x479.jpg 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/p>\n<p>Commenting on their win, Goliath said:<\/p>\n<blockquote><p>&#8220;Goliath was founded in 2012 to provide a reliable alternative to the big solar companies, after seeing so many sales-driven businesses come and go.<\/p>\n<p>&nbsp;<\/p>\n<p>From day one, our focus has been on quality service that continues well beyond installation, taking pride in our workmanship and always doing the right thing by our customers and staff.<\/p>\n<p>&nbsp;<\/p>\n<p>A big reason we\u2019ve been crowned South Australia\u2019s Best Solar Installer is that every system is installed by our own in-house electricians and apprentices \u2014 never sub-contractors. Plus, each customer works with a service and technically focused solar consultant from quote through to aftercare, ensuring a relationship that goes far beyond just a sale.<\/p>\n<p>&nbsp;<\/p>\n<p>We\u2019re humbled and proud to be recognised as South Australia\u2019s best solar installer.&#8221;<\/p><\/blockquote>\n<p>Here\u2019s what some of what the many <a href=\"https:\/\/www.solarquotes.com.au\/installer-review\/goliath-solar-and-electrical\/\">Goliath Solar &amp; Electrical reviews<\/a> on SolarQuotes from South Australian customers have had to say:<\/p>\n<blockquote><p><i>&#8220;<\/i><em>Very highly recommended. From start to finish they were very professional and caring. It\u2019s nice to see a local company genuinely give a damn about the service they provide.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p><em>They install great equipment (panels, inverters) so you don\u2019t have to worry about getting inferior products that don\u2019t do the job. And they keep the service going after the install with any thing you need.<\/em>&#8221; &#8211; Max<\/p><\/blockquote>\n<blockquote><p><i>&#8220;Goliath was excellent to deal with during our new build. I had regular check up calls and constant communication throughout. The installers were professional and easy to deal with. Very happy and would definitely use them again.&#8221; &#8211; Paul<\/i><\/p><\/blockquote>\n<blockquote><p><i>&#8220;The entire process was very smooth sailing. We looked at a few different solar companies and found Goliath to be the most honest and responsive. We didn\u2019t feel pressured to continue with them.
