Recommended Solar Systems for Chilean Market

Power structure​

In Chile, solar power is a key source of low-carbon electricity, making up nearly 40% of the total. Hydropower and fossil fuels each represent 30%. This shows Chile has made strong progress in using clean energy for power generation, but there's still potential to cut down on fossil fuel use.

 Characteristics of Different Regions​

North region: Holds 61% of the country’s solar panel installations. The Atacama Desert area gets over 2,800 hours of sunshine yearly, ranking among the world’s top spots for solar energy potential.

Central region: The main electricity consumption area (70% of national demand), but only produces 30% of its power, relying on electricity sent from the north.

South region: Hydropower is the main energy source (75% of national hydropower), but new projects are limited by environmental rules. Wind power projects are slowly increasing here.

Grid Stability Challenges​

Insufficient North-South Connection​

Chile’s north region has abundant solar resources (61% of national solar capacity) but a small population. The central and southern regions are densely populated with industries and cities, but power stations are far away. Poor transmission infrastructure means much electricity can’t be sent to users – 6TWh of electricity was wasted in 2024. This uneven energy distribution also causes big electricity price differences. In April 2024, northern electricity prices were -150€/MWh, while central prices hit 128€/MWh.​

Aging Infrastructure Issues​

37% of Chile’s transmission equipment has been in use for over 25 years. Equipment failures caused a 34% rise in power outages in 2024 compared to the previous year. For example, a storm in central-southern areas in August 2024 left 1.2 million homes without electricity, showing the grid’s weak ability to handle disasters. This also caused the solar power generation in the northern region to drop by 60% during the day.​

A countrywide blackout in February 2025 affected 98% of the population (19 million people). Santiago’s subway stopped, hospitals had to activate backup power, and economic losses topped $250 million.

PV development trend

Chile's next energy goal is to achieve zero-carbon electricity generation by 2050. Chile is currently moving towards its goals, and the proportion of renewable energy power generation has steadily increased. In order to solve the problem of balance between power production, distribution, transmission, and consumption, Chile is increasing installation capacity of ESS (Energy Storage System) in different regions. ESS become an important core in solar power system at Chile.

Recommended PV systems for Chilean Market

Chile's daily power generation usually exceeds its consumption, but insufficient energy storage leads to serious waste of solar energy. Therefore, when configuring residential and commercial solar energy solutions, UE recommends that users install the capacity of PV and batteries in a ratio of 1:1.5 to 1:2.5.
