CUSTOMER TESTIMONIALS

Thanks, Max! Initially I was reluctant to install solar panels due to the tight roofing structure of my house but your advises on maximising the efficiency of panels made me very comforting and realise I have made a great decision to install solar panels. It all thanks to you! Little did I realise the potential shade that would cast on the panel which would lower the efficiency of the panels, you caught every details and interferences with just a glimpse. Remarkable!

Thank you, STM Energy for your outstanding work! Just through your co-ordination with your work members and professionalism I expected a great result on the new outlook of the house. When you finished the work, I was even more surprised at the effort you put in every small detail and the how neat the panels look on the roof! Pleasure to your client!

My family has been using heaps of electricity on heaters and other electronic devices especially due to COVID-19 quarantine, but my energy bill was still lower than what I used to pay! An extreme gratitude for your work and the teamwork between your work members are very outstanding and comforting to see as a client! Great job and keep up the hard work!
