According to Indonesian regulations, grid-connected users must install a solar system with a kilowatt-peak (kWp) capacity that does not exceed their existing PLN capacity.. According to Indonesian regulations, grid-connected users must install a solar system with a kilowatt-peak (kWp) capacity that does not exceed their existing PLN capacity.. Ultimately, Indonesia will need to develop 0.7 GW of solar capacity annually until 2030 to meet its own renewable energy goals – and much more when considering Singapore’s requirements. [pdf]
According to Indonesian regulations, grid-connected users must install a solar system with a kilowatt-peak (kWp) capacity that does not exceed their existing PLN capacity. For new panels, expect a cost ranging from approximately IDR 10 million to IDR 20 million per installed kilowatt peak (kWp) for a standard rooftop solar system in Jakarta.
For a standard rooftop solar system installation in Bali, you can expect around IDR 10 - 20 million (+/- USD 650 - 1,300) per kWp (kilowatt peak) installed. This price typically includes solar panels, inverter, and everything else you need to get a working on-grid solar system installation. Additional costs that may occur include:
How much does a solar panel system cost in Bali and Lombok? For a standard rooftop solar system installation in Bali, you can expect around IDR 10 - 20 million (+/- USD 650 - 1,300) per kWp (kilowatt peak) installed.
Most solar installers in Indonesia usually recommend panels made by “Tier 1” solar panel manufacturers. The Bloomberg New Energy Finance uses this tiering system as a measure of a manufacturer’s reliability and consistency. The prices of “Tier 1” solar panels vary based on where they are manufactured, their efficiency and warranty durations.
The capacity of the state electricity company (PLN) is a significant factor in determining the suitable solar system size. According to Indonesian regulations, grid-connected users must install a solar system with a kilowatt-peak (kWp) capacity that does not exceed their existing PLN capacity.
The most popular solar panel brands in Indonesia are typically the more affordable top Chinese manufactured panels in the list such as LONGi, Jinko, Trina, JA Solar, etc. Here’s a rough estimate of the standard system cost for landed homes in Indonesia. Remember that installation costs will also vary depending on the above factors.

Prices typically range from Ksh. 200,000 to Ksh. 1.5 million for solar inverters in Kenya.. Prices typically range from Ksh. 200,000 to Ksh. 1.5 million for solar inverters in Kenya.. According to reliable sources, the current range of solar inverter prices in Kenya is approximately between KSh530,000 to KSh595,000.. Solar inverter prices range from KSh 15,000 to KSh 150,000, depending on the type, capacity, and features.. However, on average, the installation cost for a solar inverter system in Kenya ranges from Ksh 20,000 to Ksh 100,000. [pdf]

Here’s a ballpark range for typical residential solar system installations in Romania (excluding government incentives):Small system (3 kW): €3,000 – €5,000 (US$3,300 – US$5,500)Medium system (5 kW): €5,000 – €8,000 (US$5,500 – US$8,800)Large system (8 kW): €8,000 – €12,000 (US$8,800 – US$13,200). Here’s a ballpark range for typical residential solar system installations in Romania (excluding government incentives):Small system (3 kW): €3,000 – €5,000 (US$3,300 – US$5,500)Medium system (5 kW): €5,000 – €8,000 (US$5,500 – US$8,800)Large system (8 kW): €8,000 – €12,000 (US$8,800 – US$13,200). Romania is set to subsidize households with EUR 610 million for installing solar power panels or four times more than last year. [pdf]
Romania is undergoing a significant expansion in solar power within its broader energy transition framework, bolstered by European funding and legal reforms.
Romania has set an ambitious target to install over 8 Gigawatts of solar energy capacity by 2030, which is anticipated to constitute 24% of its gross final electricity consumption from renewable sources.
Overview of solar PV developments Following a period of lull, Romania has achieved in 2023 a significant milestone in its renewable energy journey – over 1 GW of new solar capacity installed in one year between distributed generation and utility scale projects.
The Romanian market has a good chance to add more cumulative installed PV capacity in the next 2 years, especially under net metering and self-consumption commercial and residential installations. The report provides a complete picture of the market situation, dynamics, current issues and future prospects.
Notably, a substantial private investment is set to establish the largest photovoltaic park in Europe in Arad, boasting a capacity of 1000 megawatts across 100 hectares, indicative of Romania’s commitment to expanding its renewable energy infrastructure.
This initiative aims to bolster EU states’ energy savings, clean energy production, and supply diversification. Romania is set to benefit significantly from REPowerEU, with an allocation of 1.4 billion Euros to hasten the green transition and foster renewable energy investments.
