A grid-tie photovoltaic power system is an electricity generator solar PV system that is connected to the utility grid. A grid-tie PV system consists of 2 main parts: solar panels and one or several grid-tie inverters to convert the DC current in AC current to be injected to the grid.
The solar energy collected by the panels is DC current generally has to be modified into AC current, so that you can use it. For this, we use the best inverters that can be found in the world
A grid-tie photovoltaic power system has the advantage of effective utilization of generated power because there are no storage losses involved.
ur goal is to provide you the best solution, after having made a feasibility study and a financial analysis. Working with the best brands in the world, our systems are really efficient and get good warranties.
There are three different sizes of PV power plant:
- Small residential rooftop systems > 0 to 10 kWp
- Commercial rooftop systems > 10 to 250 kWp
- Large utility-scale stations > above 250 kWp
Unlike off-grid power systems, a grid-tie system is rarely coupled with battery storage system, as they are still very expensive and not cost competitive with utility grid electricity. Besides, it’s easier to install and maintain than off-grid PV systems.
However, it can be interesting to use a hybrid system, with integrated battery. With great flexibility in terms of storage capacity and system power, this system offers the ideal solution for high auto consumption and backup in case of grid failure, in addition to an intelligent energy management.
Note specific to Indonesian’s regulations:
Systems such as Net Metering and Feed-in Tariff which are offered can lower a customer’s electricity usage costs. In some locations though, grid technologies cannot cope with distributed generation feeding into the grid, so the export of surplus electricity is not possible and that surplus is lost, excepted by using batteries.
