Solar Power

The On-Grid Solar Power System (SPS) is a commonly used system which remains connected to PLN. On-Grid SPS can meet your electricity needs during sunlight hours, and can help sell extra electricity that is unused to PLN using Net Metering. During night time the On-grid SPS draws power from PLN.

However, in the event of a power cut during the day, On-Grid SPS needs to be turned off following government regulations to prevent backflow of electricity to the grid. To protect yourself from power outage see HYBRID SPS that uses batteries.

How On-Grid System Works

1. SOLAR PANELSolar panels absorb and convert sunlight into direct current (DC) electricity.
2. INVERTERInverters convert direct current (DC) electricity into alternating current (AC) electricity which can be used by home appliances such as lamps, tv, washing machines, etc. The inverter also controls the flow of electricity so that power from the solar panels becomes the main source before the PLN network.
3. EXIM ELECTRICITY METEREXIM meter records dual electricity flows. From PLN into the building, as well as any extra electricity production from your SPS that can be sold to PLN. Payment for the extra electricity sold to PLN is in the form of electricity credits which will be used to cut monthly electricity bills.

Off-Grid Solar Power System (SPS) is not connected to PLN and is self sustaining. This system uses the most advanced technology batteries to store the electricity generated by the SPS to be used when the SPS is not producing electricity.

The Off-Grid SPS is most ideal for remote areas usage, and can be a cheaper and more environmentally friendly option compared to fuel based generators. Once installed an Off-Grid SPS needs minimal maintenance and saves you fuel and transport costs.

How OFF-GRID System Works

1. SOLAR PANEL

   Solar panels absorb and convert sunlight into direct current (DC) electricity.

2. OFF-GRID INVERTERS

   Off-Grid inverter convert DC electricity from solar panels into alternating current AC electricity which can be used by home or stored into batteries. Off-Grid inverter can be programmed to prioritize the flow from 2 electricity sources of solar panels and batteries to power the building.

3. SOLAR BATTERY

   Solar battery stores DC electricity generated by solar panels to be used whenever needed.

Hybrid Solar Power System (SPS) is a combination of On-Grid and Off-grid SPS functionality. Hybrid SPS is connected to PLN, and uses Solar Batteries to store backup electricity. A Hybrid SPS can be programmed to prioritize and balance the flow from 3 electricity sources of Solar Panels, PLN, and Batteries to power the building. Hybrid SPS has the capacity to function 24/7 despite blackouts by PLN by going into an Off-Grid Mode.

How HYBRID System Works

1. SOLAR PANEL

   Solar panels absorb and convert sunlight into direct current (DC) electricity.

2. HYBRID INVERTER

   Inverters convert DC electricity into alternating current (AC) electricity which can be used by home or stored into batteries. A Hybrid inverter can be programmed to prioritize the flow from 3 electricity sources of Solar Panels, PLN, and Batteries to power the building. When a blackout by PLN happens, the inverter would switch to using batteries and go into off-grid mode automatically to keep the building safely powered 24/7.

3. SOLAR BATTERY

   Solar batteries store the extra electrical power generated by solar panels to be used any time needed.

4. EKSIM ELECTRIC METER

   EXIM (Export- Import) meter records dual electricity flows in a process called Net Metering. EXIM records input from PLN into the building, as well as any output of extra electricity produced by your SPS that is unused by your building to the PLN. The extra electricity will be bought by PLN in the form of electricity credits which will cut into your monthly electricity bills.
