Solar Energy Systems: Grid Connected

What it is

SES-1
SES-2

In a Grid Connected Solar System, solar energy, which is linked to a feed-in grid system, supplies an entire building with electricity and reduces the customer’s energy costs. Moreover, surplus electricity generated is fed into the national grid, allowing the owner of the Solar Feed-in System to sell the access electricity to the national utility provider.

Not only does the Grid Connected Solar System produce its own energy and feeds in energy surplus into the collective grid, it also improves the effectiveness of the customer’s operations through an optional extensive battery back-up system. Should power cuts occur, the customer will still be able to operate all their electrical appliances.

How it works

SES-figure

During the day, solar electricity supplies any power requirements of the home / building with any shortage drawn in from the grid. If the solar array produces more power than what the home / building needs, then the excess solar electricity is fed out through the switchboard into the grid, running the meter backwards. At night when there is no solar power being produced, electricity is drawn in from the grid.

The end user does not need to do anything to make the system work and will notice no change at all in the way their electricity operates. The only difference is some panels on the roof, an inverter next to the switchboard and a reduced electricity bill.

Applications

For homes, offices, industrial buildings etc.

Thus far in Laos, grid connected systems have been installed at the German Embassy, at German development Service, the Deutsche Entwicklungsdienst (DED), and Deutscher Volkshochschul-Verband (DVV) International.
