PLN bill doubled for no feasible reason...

Is anyone up-to-date regarding solar penals in Indonesia? I talked with my wife about this topic today again. Always when this topic comes up we feel quite sad that it is not used more often in Indonesia and we would like to give it a try if it makes also at least a little sense financially.

But I assume there is still no encouragement (subsidy / contribution) by the government, or am I wrong? In Europe for example more and more countries support private households who install PV on the roof.

I believe @rabbit_39 was involved with solar panels. I don't know if they still are.

Many European countries are way past that point. Currently you will not receive so much subsidies anymore since they overspent. Loans etc often are still possible. Also there’s more and more taxation for those who want to provide back to the grid.

The Indonesian law which was supposed to pass in 2021 which should cover the possibilities of businesses installing roof panels and providing back to the grid, was put on hold.

Anyway, this article explains what the 2018 law stipulates when providing back to the grid with your private PLTS in Indonesia:

Pasang PLTS Atap, Tagihan Listrik Lebih Hemat

Atap surya kini menjadi pemandangan yang tidak asing di ibukota, gedung-gedung pencakar langit telah memasang modul fotovoltaik di rooftop-nya untuk menyokong kebutuhan listrik lantai-lantai di bawahnya. Jajaran panel surya yang terpasang pada atap, dinding, atau bagian luar gedung lainnya ini...

It’s quite advantageous but I’ve seen the quality of installation and equipment is not that high. The mean time before failure of some important components is 10 years which does not suffice.

If someone doesn’t want to take the leap yet on solar electricity, I would definitely still go for the proven technology of solar water heating if you have the roof space. We have installed and used it multiple times and are quite happy with the results. It beats the electric boilers and gas heaters. Every 3 years some repairs on the expansion tanks, mainly because of rust, but that still does not affect the TCO too much.

In the rainy season the yield is (obviously) less but two hours of sun per day already provides more than 200 liters of ultra hot water. Don’t forget you’d also need a pump (like Grundfos) able to handle those temperatures. I think there should be quite some posts on the forum on this already.

We have a solar panel for hot water and it is brilliant. After 10 years of unreliable water heaters that break or only provide a trickle of water, it has been amazing to have basically unlimited very hot water 24\7. I think it cost about 25jt but worth every rupiah.
