What is residual value of a solar system?
As the solar industry continues to grow and mature, more and more attention is being paid to a solar system's residual value – or the value of the system at the end of a project's life.
Why do PV inverters operate under rated power S N?
Due to intermittent solar characteristics, PV inverters operate below the rated apparent power S N during most of the day. Considering a clear sky day, the PV inverters usually generate around 30% of the total available energy . In this context, the conventional PV inverters have a considerable margin to inject reactive power.
Does a PV inverter reduce the lifetime of a system?
As expected, the inverter lifetime reduction represents economic losses, reducing the system attractiveness and competitiveness. Therefore, economic incentives must be provided to overcome the reduction of lifetime when the PV inverter compensates reactive power, as presented in, .
Are PV inverters a good solution?
Finally, PV inverters can be an interesting solution to compensate the load reactive currents and improve the power factor (PF) at the point of common coupling (PCC) . The drawback of performing this ancillary service is the impact on the PV inverter lifetime, which increases the overall system costs.
