Solar Panel Installer Perth

Perth Solar Panel Installer

Welcome to Formula Sun’s Solar Panel guide for Perth, as a leading Perth Solar Panel installer we are only interested in supplying you the most reliable and advanced Perth and Fremantle solar panels.

As the top solar panel installer in Perth, Formula Sun has listed the best suppliers available in Perth.

Choosing Your Perth Solar Panel

Here is some important background information that you need in choosing the right solar panel:

  • Only buy solar panels from an installer that supplies LOCALLY BACKED WARRANTIES, from a company WITH A PERTH OFFICE, direct imports from a supplier is asking for trouble and anybody claiming ‘exclusive panels’ just means no other installer would like to buy them.
  • We only deal with companies with locally backed warranties, not Sydney, not Melbourne, not China, locally warranted and serviced.
  • The Tier rating for solar panels is a rating for the bankability of a panel company not whether the product is perhaps 2nd rate. Having said that Tier 1 companies, in general, have higher quality control and more automated production facilities.
  • Panels will last 30 years or more. They deteriorate very slowly over time, less than 1% per year.
  • There’s no ‘magic panel’, the technologies across many brands are remarkably similar with GCL providing over 40% of the worlds solar wafers as they are the market leaders. If you look at the specifications on the product sheets, you will notice incredibly similar figures, this may fly in the face of various claims, but the specifications do not lie.
  • Be wary of ‘exclusive’ products. It usually means re-branded lower quality panels, marketed as something unique or special, very common from larger companies.
  • Be very wary of ‘independent online advice’.  Unfortunately, this does not exist.  Every regular contributor to solar forums and the like is somebody in the industry.
  • Panel efficiency is not as important as the overall size (in Kilowatts) of a system. For example, you may pay $1,200 for 4 x 250-watt GCL Panels (1kW). Or you could pay $2,000 for 3 x 330 watt Sunpower Panels (1kW). They both produce exactly the same amount of power, the only difference is how much room they take up.
  • Independent warranty insurance is when the solar company has taken out an insurance policy to cover the warranty should the panel fail and then the company fail as well. It’s an indication of incredible faith in their products. Most panel companies offer independent warranty insurance.

Solarworldsolar panel installer

You know all the reviews you read online about German-made modules? Well, Solarworld is the last one left, but probably not for much longer.

The last bastion of German made solar panels has now filed for bankruptcy. They were always a great product but high subsidies, high production costs and out of touch pricing has caught up with them. If you are offered ‘German made Solar Panels’ please contact us, as we are one of Perth’s longest serving Solar retailers and we do not know of any.

We are extremely happy to quote you on Solarworld Panels and back when they were the clear leader on quality this was all we used to install. You will pay around 50% more for Solarworlds than Q-Cells, but if you only trust German perfection these are the panel for you.

Below is SolarWorld’s data sheet:

  • Tier 1
  • German made
  • Glass sandwich construction
  • 30-year performance guarantee



Sunpower panels are the most efficient solar modules in the world. They can pack 320 watts into a panelsolar panel installer that others can only get 270 watts into. That’s 18% more efficient! The problem is they cost twice as much, that’s about $1,000 extra per 1kW.

Below is Sunpower’s data sheet:

  • Malaysian manufacturer.
  • 25-year manufacturer’s warranty (2.5 times longer than the others)
  • Tier 1
