Going solar is a dedication – it is an investment that should last you for a long time. We know it can get overwhelming, so for a start, we always advise for you to verify whether the company engaging you are certified by the Sustainable Energy Development Authority. This ensures that they are accredited installers to do installation works (USEM is a certified Registered Solar PV Investor (RPVI) license holder and holds Registered Solar PV Service Provider (RPVSP) license via its linked company, Lembah Setia Sdn Bhd).
