Elgawa supplies On- Grid Solar systems:

Solar energy is the most abundant renewable energy source we have on earth.

When the sun rays fall onto the solar panels, these solar panels generate electrical energy that can be used for the electrical devices of the user.

The solar panels produce a DC voltage that is further connected to a power inverter. The inverter changes the direct current (DC) to alternating current (AC). The inverter's AC side is connected to the main power cabinet of the consumer. This way the user can use the generated solar energy.

On-grid solar power system or grid-tied solar power system are terms used to describe the same concept:  a complete solar panel system connected to a utility's power grid.

With a surplus of solar energy during the day, when the user's energy consumption is lower than the amount of solar energy generated, this excess of solar energy is injected back to the electricity grid. The utility monitors this backfeeding through the kWh meter, and compensates the customer for the amount of energy returned to the network on the electricity bill. In this way, the user can return his investments in a certain amount of time by the energy returned to the electricity grid.

During the night or when the user's demand exceeds the amount of solar energy generated, this lack of energy is provided by the utility. In case no power is supplied by the utility during the day, it is also necessary that the inverter stops functioning. This will prevent the tension in the utility’s network from rising.

When installing an on-grid solar power system, the user may see a significant difference in his energybill.
