Solar-Log WEB-4U: Modern PV Plant Monitoring


Faults in the functioning of photovoltaic plants that are detected too late can have serious effects on their energy yields. Financial losses and thus lower profitability are often the results. In order to prevent possible malfunctions and to be able to react quickly in the event of a problem, professional PV plant monitoring is required.

But how is the monitoring optimally implemented in photovoltaics? As a rule, installers offer their customers a service contract that includes the monitoring of the PV system and fault identification. If a problem arises that needs to be solved on the spot, a service call can be made promptly.

The more service contracts an installer has concluded, the more time it takes to complete the service. The daily monitoring and error evaluation of PV plants, in particular, require a great deal of time and resources.

In order to support installers, Solare Datensysteme GmbH (SDS) offers its service Solar-Log WEB-4U. A team of experts from SDS takes over the PV monitoring for the installer. All incoming error messages are analyzed and evaluated by SDS. The installer will then be contacted and informed proactively. Using his mobile devices, such as a smartphone or tablet, he can receive the messages at any time and initiate an immediate service call if necessary.

By handing over PV monitoring to SDS, installers save time and personnel resources which they can use for activities at the customer's site.

HEKA energy from Nußloch (Germany) is one of many companies that have already decided to hand over the PV monitoring to SDS. Christian Geierhaas, the project manager at HEKA, says: “We first tested Solar-Log WEB-4U with a few PV plants. We came very quickly to the conclusion that the service is a great help for us. The time we had to spend on monitoring customer plants in the past, can now be used for our core business. As a result, we are much more flexible and have less time pressure. Professional monitoring of the plants is guaranteed at all times by Solare Datensysteme GmbH.”
