PV Doctor provides an advanced and comprehensive range of asset management services for photovoltaic (PV) system owners across Asia. The company started full operation in April 2025 and now provides services directly to industry customers. In less than a year, the team has on-boarded more than 1 GWp of PV assets across more than 1300 sites in 21 countries across the world (see map below).
PV Doctor Pte Ltd is a PV Asset Performance Management (APM) company which commercialises the know-how and services previously developed in the Smart O&M Group at SERIS. It also leverages the vast experiences with PV systems (design, implementation, operation, troubleshooting, maintenance) which SERIS has gathered over the past 15 years in Singapore and the region.
The importance of daily monitoring of solar PV systems (and ideally in real time) cannot be overstated, given the number of PV assets that are under-performing in the world (a global assessment by a consulting company estimates annual losses of USD 10 billion worldwide). Poorly operating PV systems can also pose safety and/or fire risks, which must be mitigated.
PV Doctor offers a broad range of services which aim at increasing PV system performance, energy yield and, in consequence, also revenue – to secure (or ideally even raise) the return of investment of the asset owners.
