PV Plant Repowering

PV plants performance can diminish over the years for a variety of reasons, from module degradation to a host of other causes. Alencon technology can help breathe new life into your PV plant by maximizing power output from your existing modules and decreasing line losses to your central inverter.

Additionally, many older PV plants are now suffering inverter failure and those new inverters are needing to be replaced. 

Alencon’s SPOT DC-DC optimizer solution represents a cost effective way to upgrade your existing PV plant to increase the amount of energy it is producing. Our DC-DC optimizers will provide you string-wise maximum power point tracking (MPPT) on up to four separate strings at once. This powerful functionality is particularly helpful when optimizing power across strings that may have degraded differently over time, have different power ratings or are even from different manufacturers. Should you need to replace a failed inverter, the Alencon's SPOTs are a great solution for bridging the voltage gap between older, lower voltage panels and newer, higher voltage inverters.

Watch this video to see how Alencon's SPOT solution can be used to repalce a failed or failing 600 volt central inverter with a new transformerless inverter:
