In a grid-tie system, there are no batteries, and all the solar energy generated is fed to the loads directly. The solar PV system is synchronized with the grid to maximize the use of renewable energy while catering to the connected load in the facility.
In the event of a drop in the production of solar energy the loads automatically source the remaining energy required, from the Utility/DG supply without any interruption. In the event of a power failure, the solar PV system will continue to work in sync with the DG thus providing an uninterrupted power supply to the load connected.
A grid-tie system does not provide backup power during a power outage but reduces the EB and DG consumption by maximizing the use of solar energy.
A grid-connected/grid-tie system works very well when the majority of the operation for a given facility is during the day and the facility is energy intensive with backup available for power outages.
Battery-based systems store the solar energy generated during the day, in batteries, for later usage. An intelligent inverter blends solar power generated with the grid power to supply the loads.
Solar power is always preferred over grid power thereby reducing overall grid usage. In the event of a power failure, solar power (via the battery bank) takes over completely.
Such systems can essentially be either a simple backup system for power cuts or a completely off-the-grid system where all your energy needs are met by solar power.
Module mounting structures for Solar PV systems are designed to maximize the generation with its optimal tilt while also ensuring that they are capable of withstanding prevalent weather conditions.
Other than these, Viking Renewable offers customized mounting structures for its installation with a complete study of load bearing capacity of the building while also considering the aesthetics and functional aspects of access to the roof area.
For eg. in facilities where the flat roof area is covered with chillers and other HVAC-related equipment, our structural offerings can allow for the mounting structures to be raised in order to facilitate access to the rooftop space while also being able to use the area for PV installation.
Our customized offer for mounting structures includes:
