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.

To determine the required solar panel capacity (in watts), divide the total daily energy consumption (including losses) by the average daily sunlight hours. [pdf]
To calculate the solar panel energy output, the panels must be measured under average conditions, also known as STC or Standard Test Conditions. This means that the STC measures the output of the solar panel by using common conditions of the factors affecting the output.
By inputting information about your energy consumption, the calculator can provide an estimate of the size and configuration of a solar panel system that would best meet your needs. Alternatively, you can contact us to discuss your specific energy needs and we can tailor a solar power solution that is customized to your requirements.
To determine the required solar panel capacity (in watts), divide the total daily energy consumption (including losses) by the average daily sunlight hours. It's recommended to consult with a solar system professional or engineer to fine-tune your calculations and get a better understanding of the specific solar conditions in your location.
For each appliance, multiply its power rating by the average daily usage in hours to get the daily energy consumption in watt-hours (Wh). Add up the daily energy consumption of all appliances to get the total daily energy consumption in watt-hours. Solar systems aren't 100% efficient. You'll need to factor in efficiency losses.
Divide the total daily energy consumption (including losses) by the number of usable sun hours in a day to get the required battery capacity in watt-hours. To determine the required solar panel capacity (in watts), divide the total daily energy consumption (including losses) by the average daily sunlight hours.
