You should do that because it saves you large amount of money and it also saves the world from green house gases! The cost of solar PV has reduce significantly in recent years and generating your own solar energy at your house/shop/factory is now cheaper than paying for electricity from PLN. Large-scale solar PV has also become cheaper than diesel/petroleum generators and it is already competitive with coal and natural gas generators too.

And the best thing about solar energy is that it does not need any fuel and are built to be long lasting up to 25 years and maintenance free, so you don’t need to worry about anything once the solar PV system is installed and just simply enjoy the perks of it.

Yes, you will still receive electricity bill from PLN as long as you are still a PLN customers. This is because the solar panels on your roof only produce energy when there is sun. During rainy days and at night, you will still be relying on PLN to fulfil your electricity consumption.

The beauty of solar PV system is that it is maintenance free. There is no fuel to be replaced and there is no moving parts. The only thing you need to do is make sure that the solar panels are clean (free from dust, leaves, or any other items). It is good practice to clean your solar panels twice a year to make sure that they are free from pollution, or even bird droppings!

Our Alva Energi app will also inform Alva Energi staff should there be anything unusual with your solar PV system and we will solve the problem immediately.

Indonesia receives relatively high amount of sunlight. For every kiloWatt-peak (kWp) that you install, you would receive about 4 kiloWatt-hour (kWh) per day. This means that for a household that install 5 kWp of solar panels, they would get about 20 kWh per day, equivalent to approximately the electricity consumption of 3 aircon run for 8 hours.

The more sunny the area, the more energy the solar panels will generate.

A typical on-grid solar PV system consists of solar panels, an inverter, an electrical box (may or may not be required, depending on the installation), and a PLN net meter (kWh exim).

The solar panels are usually installed on your rooftop, since it should not be blocked by any building/object to get the most amount of sunlight. The inverter and electrical box are ideally located as close to the main electrical panel of your building as possible.

The net meter will replace your current PLN meter.

Solar PV systems have a lifetime of at least 25 years. That being said, there are many systems installed over 30 years ago and they are still functioning now. So you can rest assured that your solar PV system will last for a long time.

No, solar PV is now among the cheapest sources of electricity thanks to the rapid cost reductions in recent years. The electricity produced by Solar PV power plant is now even cheaper than that by natural gas power plant.

If the cost of carbon emissions and other environmental pollution is also taken into account, solar PV will be economically competitive with any fossil fuel generators, like coal and oil.

If you are unable to obtain the information yourself from the methods described in answers below, you can also connect us to people who can answer it for you (e.g. your electricity contractor or architect) or call us for a site visit to your property.

Solardexenergy expert staff will use the information to design the system catered to your needs, so that you will get the most energy from the sun. We will then send you a proposal and quotation for your solar PV system, free of charge!

No, You can just sit back and relax while Solardexenergy staff takes care of obtaining the permission from PLN for you.

We will need someone to be at home to give us the permission and access to your roof and some locations within the house for.

The solar panels, together with the mounting structure, only weigh about 20 kg per square meter, which is within the weight limit of most roofs. Before any installation, Solardexenergy expert staff will do a site visit to check the suitability of your roof for solar panel installation. We will inform you if your roof is not suitable or if you need additional reinforcement. Moreover, our installers are well trained and will uphold the highest engineering standard while installing the solar panels on your roof. So you can rest assured that the installation will not cause your roof to break or cause any leakage to the house.

A one-year installation warranty for the system is provided free of charge. This warranty is not transferrable. In the unlikely case of problem or failure pertaining to the installed PV system, technical support will also be provided for free within one year of installation. After the one-year warranty period has expired, technical support can be provided with additional fee.

The equipment is subject to warranties from the respective manufacturers:

1. Solar panels have a 10-year product warranty and a 25-year linear power output warranty from the manufacturer.
2. Inverter usually has a 5-year product warranty from the manufacturer (warranty extensions are available upon request, subject to additional charges).

Should there be any damage to the above-mentioned components, Solardexenergy will help you to contact the respective authorized distributors/manufacturers. However, any costs incurred will be borne by the owner.

We equip your solar PV system with a remote monitoring solution, so you (and we) can see the real-time performance of the solar PV system through Solardexenergy app on your phone and other devices. We will be notified if there is anything unusual or problem in your PV system, and will work to solve the problem immediately.

Solardexenergy gives one-year warranty on the installation.

On the one hand, off-grid PV system requires either battery or diesel generator to form its own grid, to keep functioning when there is no sunlight (when it’s raining and at night). Therefore additional cost is required to purchase the batteries and diesel generators. Moreover diesel generators also require diesel to run, which can be very expensive to obtain in remote places.

On-grid PV system, on the other hand, does not need any battery or any diesel generator to function. The on-grid PV inverter will follow the voltage and frequency of the PLN network. When there is not enough power from the solar PV system, your property will take the remaining demand from the PLN.

Yes, absolutely! So you don’t need to worry about extra charges on top of our quotation.

What you pay us for the net meter will be the price that the PLN charge us. We will not take profit from setting up the net meter for you.

Net meter means that you are able to export and import electricity to and from PLN as necessary.

During the day, your solar PV system will produce electricity. This electricity will first be used to fulfill the electricity consumption of your property (e.g. lighting, air conditioning, water pump, refrigerator). If the electricity generated by your solar PV system is more than your electricity consumption, the surplus electricity will be exported to the PLN network to be used elsewhere. When your solar PV system is producing less electricity than required by your property, the rest of the electricity will be imported from the PLN network.

The net meter will replace your current PLN meter.

At the end of each month, when you receive the electricity bill from PLN, there will be a section on energy export (the electricity generated by the solar PV system that is exported to PLN). This section will mention how much electricity has been exported to PLN for that month, and will show the savings that you get from the export.

As stated in the Ministerial Rule of Energy and Mineral Resources No. 49 2018, the exported electricity to PLN is calculated from the export reading on the net meter, multiplied by 65%. In other words, the electricity from solar PV system exported to PLN is only worth 65% compared to if it’s consumed locally.

If your property is an office, factory, or any other facilities which consume electricity during the day, there is unlikely to be any power exported to PLN even during the day, and so the 65% rule will not apply to you.

Off-grid PV system is usually suitable for electricity consumers who are located far away from PLN, such as remote industries, island resorts, remote telecommunication towers (BTS), remote villages, hospitals in rural areas, etc.

Urban electricity consumers who want to be independent from PLN and generate their own clean energy can also choose to install off-grid PV system. However, to fulfill your electricity solely using solar energy, and to keep the cost to a minimum, you would have to reduce your energy consumption as much as possible, such as by minimizing, or even completely removing, the use of air conditioners and other energy-intensive electrical appliances.

A Solar Home System (SHS) is a small off-grid PV system, usually consisting of 1 solar panel, 1 battery, 1 charge controller, 1 phone charger and 2-3 LED lights. One SHS is typically used for one house. SHS represents the most basic form of rural electrification, giving people access to lighting and phone charging.

Whereas SHS is only for one house, Communal Solar PV can be used to power a kampung, a desa, or more. The system is centralised, with more solar panels and larger battery banks compared to SHS. The electricity from the Communal Solar PV is then distributed to individual houses and facilities using distribution cables.

The net meter will replace your current PLN meter.

Based on our experience and detailed calculation, SHS is usually more economical for a kampung if there are fewer than 10 houses in the kampung and/or if the houses are located far away from each other. For a larger and more densely spaced kampung, Communal Solar PV is usually the more economical solution.

The app allows you to monitor the amount of energy and savings that your solar PV system produces. You can also make sure if the system is working perfectly as intended.

At very low penetration of PV in the grid, there is no negative impact to PLN. At higher penetration of PV, there may be some negative impacts caused by the intermittency of solar energy and the fact that it is only available during the day. The impact and the amount of solar PV systems installed that will trigger the impact highly depends on the specific grid parameters.

Since solar PV system (in particular rooftop solar PV) generates electricity close to, or directly where it is consumed, it would reduce the need to transmit this electricity from distant generators. This means that solar PV systems will reduce the power losses in the system and increase the transmission and distribution capacity of the grid cables. This may also allow PLN to postpone their upgrades.

All of these are on top of the enormous environmental benefits that would be obtained by shifting the electricity generation from fossil fuels to renewable energy.
