Connecting solar and wind parks

Connecting solar and wind parks

The usage of solar panels is growing exponentially. Consumers and companies alike install more and more solar panels, while companies even construct their own solar parks. Solar panels are not only highly sustainable, but can also result in a significant cost reduction, especially when they are combined with an energy storage solution that stores the sustainably generated energy to sell it to the main grid when the highest rates are offered. Due to our extensive experience with large energy projects for both industrial and horticultural organizations, Alfen can construct complete solar parks for every type of company. Alfen provides full service to its clients, by caring for every step of the process: from delivering the panels, to completely installing them and providing for daily management and regular maintenance.

Generator connections

The connection of the medium voltage cable to the generator is an essential part of the electric installation. Daily practice proves this is a weak point in many infrastructures, often being the source of a significant disruption in continuity for companies. With the Sicuro, Alfen provides for junction boxes that guarantee a reliable generator cable connection. This solution helps to prevent cable lug ruptures and therefore contributes to securing organizational continuity. In addition to a safe connection, the Sicuro also enables switching the generator. The generator junction box delivered by Alfen requires no maintenance at all and has a guaranteed lifecycle of at least 50,000 switches; over ten times as more as traditional switches. Using a Sicuro therefore doesn’t only add to reliable generator switching, it also contributes to a significant saving on operational costs.
