    Fantastic experience from start to finish! The team at Spectrum provided clear, honest advice and helped me understand my solar options without any confusion. The installation was smooth, professional, and completed on time. The difference in my energy bills has been incredible! Their post-installation support was also excellent—checking in to ensure everything was working perfectly. Highly recommend their services to anyone considering solar energy!

    Brilliant company to deal with. From the initial chat about my requirements to installation, I can’t fault one thing. I found Solar somewhat a minefield with some people trying to bamboozle me with information but Spectrum helped explain it in simple terms. The installation was faultless and they even called me 2 days later just to check everything was running OK. 10/10 team. Would definitely recommend.

    Exceptional service and professionalism from Spectrum! The team guided me through the entire process, making everything easy to understand. The installation was seamless, and the quality of work was outstanding. I’ve already noticed a significant drop in my energy costs. Plus, their after-sales support has been fantastic—they genuinely care about their customers. I couldn’t be happier with my decision to go solar with Spectrum!
