GRID-TIE SYSTEM

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 SOLAR PV

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.

CUSTOM MOUNTING STRUCTURE

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 Solar 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:

  • Grout less and grouted structures
  • Special structures for industrial rooftops, sloped roofs, etc.
  • Lightweight and rust-proof structures
  • Robust structures to withstand high wind speeds
  • Parking canopy structures (Car parks as mounts for Solar PV systems)

Barahonda – 12 MW – Spain

Barahonda 12 MW

In the Municipal Term of Jumilla, (Murcia), Spain, a private Estate known as Barahonda, is situated. For its location in the Catastral Registry, Polygons 194 and 195 of the Region of Murcia, are given as a location reference.

The approximate total extension of Barahonda is 1,500,000 m2, mostly dedicated to the cultivation of vineyards.

It is the last private Estate within the Region of Murcia bordering the Province of Albacete, (Castillo la Mancha).

In the highest part of the Estate, and within its boundaries, “La Sierra de Los Ladrones” is situated. This mountain range is the natural border between the Autonomous Region of Murcia and the Autonomous Region of Castillo la Mancha. It has the highest Geodesic vertex in the area, 987m above sea level.

In this mountain range a wind power plant, known as Los Reventones, has been built. It has a total energy output of 40 MW.

The installation and building of the Plant are planned to start in March 2007 and it is envisaged the plant will be ready by the end of December to the beginning of January 2008, to start normal production by mid-February.
