The battery industry plays a crucial role in the global energy transition, particularly in facilitating the rapid development of renewable energy sources. As solar photovoltaic technology is widely adopted around the world, energy storage systems have become a key factor in ensuring energy stability. Valve-regulated lead-acid (VRLA) batteries, due to their low cost, low maintenance, and adaptability to various environments, have become highly favored, especially in the African market.
Africa faces significant challenges with electricity access, and the growing demand for off-grid and microgrid systems has driven the need for reliable energy storage solutions. VRLA batteries, with their affordability and reliability, have become an essential part of solar energy storage systems in the region. This report analyzes the current status, demand trends, and future potential of VRLA batteries in the African solar market.
As of 2024, the global VRLA battery market is estimated to be valued at $6.5 billion, and it is projected to grow to $9.5 billion by 2030, with a compound annual growth rate (CAGR) of 6%. Compared to lithium-ion batteries, VRLA batteries have a significant cost advantage. In 2024, the average unit cost of VRLA batteries is approximately $80-120 per kWh, while lithium-ion batteries are priced at $130 per kWh.
In the renewable energy sector, particularly for solar energy storage, VRLA batteries continue to hold a substantial market share. Globally, approximately 15% of solar photovoltaic projects rely on VRLA batteries, particularly in developing countries and less economically developed regions where VRLA batteries are a cost-effective choice.
Africa remains one of the least electrified regions in the world. As of 2024, an estimated 600 million people across the continent lack access to reliable electricity. This presents a significant opportunity for the expansion of solar photovoltaic and energy storage systems. The African solar market is experiencing rapid growth, with 6.5 GW of new capacity expected to be installed in 2024, primarily in East and Southern Africa.
The African solar energy storage market is projected to grow at a CAGR of 8.7% from 2024 to 2030, with the market size increasing from $1.1 billion to $2.2 billion. Currently, around 65% of newly installed solar systems are equipped with energy storage, and 40% of these storage solutions rely on VRLA batteries, especially in remote areas where affordability and ease of maintenance are critical.
The core competitiveness of VRLA batteries in Africa lies in their low initial cost and minimal maintenance requirements. In rural solar energy storage systems, 80% rely on VRLA batteries. These batteries are widely used in small and medium-sized solar projects, especially in remote and lower-income areas. VRLA batteries are also well-suited to high-temperature environments, making them the preferred choice for many solar projects across the continent.
Kenya and Tanzania have seen significant increases in solar PV + storage projects. In 2024, approximately 85% of newly installed solar systems in Kenya’s rural areas used VRLA batteries, with the overall solar market growing by 11%.
In South Africa, the government’s “Solar Village Plan” aims to provide off-grid power solutions to 3 million households. It is expected that 60% of the storage systems under this plan will use VRLA batteries, contributing to the country's solar energy development.
Although lithium-ion batteries dominate the global energy storage market, VRLA batteries remain the top choice in Africa due to their low cost and ease of maintenance. The average cycle life of VRLA batteries is 600-1000 cycles, making them suitable for off-grid solar projects in Africa. Their average lifespan is 5-8 years, and they perform well in solar photovoltaic applications.
Over the past decade, the price of lithium-ion batteries has dropped significantly, from $1,100 per kWh in 2010 to $130 per kWh in 2024. Despite this, VRLA batteries maintain their advantage in the African market due to their lower initial cost and better performance in high-temperature environments, which are common across many parts of Africa.
As African countries increase their investments in renewable energy, battery recycling technology has also seen significant improvements. By 2024, the lead-acid battery recycling rate in Africa is expected to reach 80%, far exceeding the global average. Advancements in recycling technologies have enhanced the sustainability of VRLA batteries, reducing their environmental impact.
The main challenge for VRLA batteries lies in the global supply chain. Lead, a key component of VRLA batteries, is subject to price volatility and supply disruptions, which could impact production costs. In 2024, lead prices have increased by 10%, placing pressure on the market. Additionally, VRLA batteries have lower energy density and require regular maintenance, limiting their application in high-demand solar projects.
Despite these challenges, the rapid growth of the African solar energy storage market presents numerous opportunities for VRLA batteries. Government policies supporting renewable energy, such as South Africa’s Renewable Energy Incentive Program and Kenya’s Solar Development Subsidies, provide a favorable environment for the expansion of VRLA battery applications. Over the next few years, the growth of solar + storage systems is expected to create a 60% increase in market opportunities for VRLA batteries, particularly in off-grid and microgrid projects.
Based on current trends and data, the African solar energy storage market is expected to reach $2.5 billion by 2030. Throughout this period, VRLA batteries will continue to play a crucial role in off-grid and microgrid systems. By 2028, the demand for VRLA batteries in Africa is projected to reach approximately 1.5 million units per year, with more than 70% of demand coming from solar projects in East and Southern Africa.
VRLA batteries, due to their affordability and reliability, will continue to be a critical component of solar energy storage systems in Africa over the coming years. Africa's electricity shortages and reliance on off-grid power systems create sustained demand for VRLA batteries, especially in economically underdeveloped and grid-unreliable regions.
As the African solar photovoltaic market continues to grow and government support strengthens, VRLA batteries will maintain their market advantage despite competition from lithium-ion batteries. With technological innovations and cost control measures, VRLA batteries are expected to further expand their market share in the African energy storage sector in the coming years.
