Solar Power by Piment Rouge

GOING GREEN IN BALI WITH PIMENT ROUGE
SOLAR POWER SYSTEM

We converted our showroom in Bali to solar power. As we are a business that operates during daylight hours, we decided it would be a more energy efficient way to operate.

We installed 14 solar panels [300 watts per panel]. We connected the panels to an on-grid inverter box. This box prioritizes solar use and when not available, it switches automatically to the grid. And voilà, done!

It cost us 99 million rupiah to run up to 2600 watts off-grid. An additional 3.5 million rupiah applies to register the system to PLN and have a grid backup.

HYBRID INVERTER BOX IN PIMENT ROUGE
SOLAR POWER SYSTEM

– Solar off-grid system without battery, 35% cost off compared to traditional solar system
– Connect generator & PV complementary
– Wide input voltage range can adapt to many areas and complex power grid
– GPRS & WIFI network

TECHNICAL ADVANTAGE OF HYBRID INVERTER BOX IN PIMENT ROUGE SOLAR POWER SYSTEM

It can be running without batteries, energy share from utility and solar to loads alternatively. Without batteries, it can help to reduce the solar system cost and more importantly it can save electricity fee.

It combines a high PV input MPPT controller, it can convert solar energy from PV to load directly and at the same time the remaining solar energy converted to batteries.

When PV output is reduced by clouds or at night, resulting in no surplus PV power available, loads powered by utility and batteries is charged, when utility outage, battery is discharged.

HOW THE HYBRID INVERTER BOX WORKS IN PIMENT ROUGE SOLAR POWER SYSTEM

• Off grid solar system working without battery.
• 3.2KW or 5KW full capacity output 220V, 230V, 240V [optional].
• PV input 120VDC – 500VDC.
• PV plus grid take the load together.
  For example: your power consumption is 5KW/H, you get 4000W/H from PV, inverter will get grid 1000W/H to take load [save electricity bill]

MONO CRYSTALLINE MODULE AS OFF-GRID SOLAR PANEL IN PIMENT ROUGE SOLAR POWER SYSTEM

IP68 junction box & connector:
IP68 Junction Box and Connector have a high degree of waterproof, effectively resist the harsh environment.

15A current:
The junction box carries a current of 15A, ensuring high current flow through the modules.

Super strong frame:
Glue-spilled tank has a double-layer waterproof, cross-section with hook-shaped aluminum frame, enhanced by 10% of the mechanical load strength.

Current division:
The module refines the current division, thus effectively reducing the loss of up to 2% due to mismatch and increasing the power output of the system.

Salt spray, ammonia, and PID test:
Excellent salt spray resistance, anti-ammonia, and anti PID, TUV, SUD certification approved.

Strong mechanical load capacity:
Passed the 2400pa wind load and 5400pa snow load test, ensuring that the module has a stable mechanical life.

Color classification:
Modules are packaged according to color classification, to achieve consistent appearance after installation.

NET METERING FEATURE IN PIMENT ROUGE SOLAR POWER SYSTEM

What is Net Metering?

Net Metering is a service to an electric consumer under which electric energy generated by that electric consumer from an eligible on-site generating facility and delivered to the local distribution facilities may be used to offset electric energy provided by the electric utility to the electric consumer.

In Indonesia, Net Metering has been mandated by PLN in Regulation 0733.K/DIR/2013 [December 2013], which obliges PLN to ‘credit’ energy produced by solar to a customer’s account. To apply Net Metering, customer simply applies for installation of a 2-way meter.

Battery Storage VS Net Metering

Solar systems produce power from sunlight. They only produce electricity when there is sunlight and the level of production is directly related to the level of sunlight available. Solar is not an on-demand electricity source. This presents a problem in that demand and supply are not automatically matched: sometimes there is more energy demanded than supplied, and sometimes it is the other way around.

The normal solution to this mismatch is “storage”, so that when supply exceeds demand, the surplus gets stored, and when demand exceeds supply, the shortfall is taken from the storage. The problem with this is that electricity can only be stored in chemical batteries, which are not very efficient, very expensive, and do not last very long. Having to use a battery bank to overcome mismatches of load and supply is very painful.

Instead of locally storing the surplus energy locally, it gets sent into the grid [basically for someone else to use], and you get credited. Your electricity meter measures: a) the energy coming in from the grid, and b) the energy going out to the grid, and you only pay the difference.

This means that you can “over-produce” during the day and use that over production at night. It allows you to become “net-zero” energy from the grid.

Feed in Tariffs VS Net Metering

Feed-in Tariffs work in the same way, except that the energy you feed in to the grid is valued higher than the energy you take out of that grid, so you actually profit from the energy you feed in.

How Does Net Metering with PLN?

1. PLN installs a kWh meter of the “import export” type for PLN customers that use electrical energy from Photovoltaic next to from PLN.
2. The electrical energy “received” by PLN will be offset by the electrical energy that PLN sends to the customer.
3. In the case where the amount of PV-generated electricity received by PLN as mentioned in point 2 above is bigger than the amount of electricity supplied by PLN, then the surplus will be made eligible as kWh-credits to be accounted for the following months, and so on.
4. The customer will continue to pay Minimum Account connection charges while still connected to the PLN.

To apply Net Metering to your PLN bill, we simply have to request the 2-way meter type from PLN. In some cases, they may inspect the installation.

KEY FACTS OF PIMENT ROUGE
SOLAR POWER SYSTEM

When connected to PLN with net metering, they require you to use 10% off the grid. Example: from 4400 KW Meter, 440 W must be used from PLN.

Cost from PLN to install net metering is Rp3.000.000,-
Cost of survey from subsidiary company is Rp500.000,-

Example: we buy our electricity from PLN at Rp1.467,- per KW, using net metering they will buy back unused solar power from you for Rp953,- » This will help offset your electricity bill.

Example of power obtained from solar system:
From 5000 KW solar inverter with 24 panels, you would expect in midday to receive 3000 W from the installation.

Typical example of cost of installation of solar power energy starts from Rp68.000.000,- installed. It will give you 1200 W of power in peak sun.
