Why Solar?

The price of electricity continues to climb in a very predictive fashion, but the price of solar panel system has drastically decreased in the past couple of years. The sun and the solar energy sector are very pleased with this, of course, which is perhaps why you can now see a greater return on investment (ROI) on solar installations.

Residential Solar System

With Isolux Solar, you can generate your own electricity and even get paid for the excess energy you produce by feeding it back into the grid. Our residential solar panel systems offer a cost-effective way to lower your power bills and take control of your energy usage. Start saving with a home solar panel system today!

Commercial Solar System

A commercial grid-connected solar power system works similarly to a residential one, allowing you to use power as it’s generated during the day. This can help meet the energy demands of your business while reducing reliance on the grid. Whether you operate during peak hours or require backup, our commercial solar solutions are designed to deliver consistent performance and energy savings.

  I have just installed Solar in my investment property, I am very happy with the installation, professionally done all the job. It was hassle-free process. Gary Smith helped me a lot to choose the right Solar panel and inverter and gave me very good deal. Thank you so much for your genuine suggestions and looking after me very well Mr. Gary.
I 100% recommend them to you all. They are very professional. Love them 🙏

  I received quotes from several providers and found that they were either unprofessional or too expensive. Before making a final decision, a friend recommended ISOLUX, so I spoke with Gary in sales. He was knowledgeable and patient. The installation team arrived before Easter and completed the job perfectly in one day (installing 25 panels and battery). I highly recommend this team!

  I recently received a quote from Isolux to install a 13kW solar system. I didn't know a lot about solar, but Gary from Isolux explained the whole process (pre install paperwork, installation date and connection to the grid) and offered a great price. Installation was quick and professional. I would recommend Isolux if you're looking for solar.

  Strongly recommend to speak to Isolux before choosing an installer.

I reached out to several solar panel installers and almost all of them advised solar isn’t a variable solution for us sighting trees and neighbouring building doesn’t allow enough sunshine.

Reached out to Kunal on a friend’s recommendation. Kunal visited in person and sent a viable option in few days and advised right number of panels and other specs balancing investment and return.

We went with Isolux and made the right choice. We are almost net neutral in power.

Kunal and his team are very professional and transparent right from start. Installed on time, no surprise costs and excellent support even after installation to address few queries.

  I had the pleasure of discussing my solar system needs with Gary Smith, Senior Sales Executive. he is very receptive to our discussion and recommended a system suitable to our needs. He is readily available and inspired confidence to the installation process. The installation is carried out efficiently. My thanks to Gary and I have no hesitation to recommend discussing your solar system needs with him
