Laos is embarking on an innovative energy venture, planning to install floating solar panels on its vast hydropower reservoirs. With a goal to produce 2,000 MW of renewable energy by 2030, this initiative is a cornerstone of the government’s strategy to expand its green energy portfolio and reduce over-reliance on traditional hydroelectric power.
Ministerial Directive and Project Overview for Laos floating solar
The Ministry of Energy and Mines has officially announced that the Lao government will permit hydropower providers to install floating solar panels on their reservoirs. This directive is a key component of the government’s broader energy strategy to diversify its energy sources and accelerate renewable energy production.
Under this plan, each hydropower provider is authorized to install solar panels capable of generating up to 10% of the reservoir’s total energy output. For instance, a hydropower plant producing 100 MW can supplement its output with up to 10 MW of solar energy. This hybrid approach aims to create a more consistent and reliable power supply, as solar generation during the day complements hydropower, which can be dispatched as needed, especially during peak evening hours or dry seasons when water levels are lower.
Laos has set an ambitious target to produce 2,000 MW of renewable energy by 2030. This goal includes generating 1,600 MW from solar power, 400 MW from wind power, and 5 MW from biomass by 2025. The installation of floating solar panels on hydropower reservoirs is a significant step towards achieving these targets, as it intelligently leverages existing infrastructure to boost the country’s renewable energy capacity.

Advantages of Laos floating solar Panels
Floating solar panels, often called “floatovoltaics,” offer several distinct advantages over traditional ground-mounted solar installations. They are installed on floating structures in bodies of water like reservoirs and lakes, a crucial benefit in a country like Laos where land use can be contested between energy production, agriculture, and conservation. This approach conserves valuable land resources that can be used for other essential purposes.
Additionally, floating solar panels can help mitigate water evaporation from reservoirs by providing shade and lowering water temperatures. This is particularly beneficial in regions prone to water scarcity, as it helps preserve water levels in reservoirs critical for both energy production and irrigation.
The cooling effect of the water beneath the panels also enhances their efficiency. Solar panels, like most electronics, perform better in cooler temperatures, which can lead to higher energy output compared to land-based installations exposed to higher ambient heat. Furthermore, the existing infrastructure of hydropower plants, such as grid connections, transmission lines, and maintenance facilities, can be utilized for the solar panels. This synergy significantly reduces the overall solar panel manufacturing plant cost breakdown and complexity of the installation compared to building a standalone solar farm from scratch. Understanding the basics of solar panel manufacturing helps appreciate the technical and economic efficiencies gained from this hybrid model.
Impact on Laos’s Renewable Energy Objectives with floating solar
The integration of floating solar panels into Laos’s energy infrastructure is a critical step towards achieving the country’s renewable energy objectives. By 2030, Laos aims to increase its solar power capacity to 1,600 MW, with these hybrid hydro-solar installations playing a significant role in this expansion.
This initiative is also part of a larger regional trend. Neighboring countries are also exploring this synergy, as detailed in the Thailand Solar Panel Manufacturing Report, which highlights similar hydro-floating solar hybrid projects. By adopting this model, Laos not only enhances its energy security but also positions itself within a progressive regional movement towards diversified and resilient energy systems.
This strategic diversification reduces dependence on traditional hydropower, which has faced criticism for its environmental and social impacts and is vulnerable to climate change-induced droughts. Floating solar panels offer a more sustainable alternative, as they have a smaller environmental footprint and can be integrated into existing water bodies without significant disruption to local ecosystems. The entire solar panel manufacturing process, from sourcing solar panel raw materials to final assembly, is geared towards creating a durable product suitable for these unique aquatic environments.
The Lao government’s decision to install floating solar panels on hydropower reservoirs marks a significant milestone in its journey toward a sustainable energy future. This initiative will help the country diversify its energy sources, reduce its environmental impact, and contribute to global efforts to combat climate change. With a target of producing 2,000 MW of renewable energy by 2030, Laos is positioning itself as a leader in innovative and sustainable energy development in Southeast Asia.
