JA Solar launches integrated PV storage system for microgrid

As energy reliability and sustainability become critical priorities for commercial and industrial (C and I) operations, JA Solar Technology Co., Ltd. has introduced an advanced Battery Energy Storage System (BESS) designed for on-grid and off-grid C and I microgrids

The integrated PV storage generator solution tackles core energy management challenges, providing a dependable framework for businesses operating in regions with unstable power supply. By combining solar photovoltaic generation, energy storage and backup generators, the system delivers continuous power, cost efficiency and environmental gains.

C and I energy environments face a range of challenges. Unreliable grids and frequent load shedding result in expensive downtime, disrupting operations and productivity. Fluctuating electricity tariffs, alongside dependence on diesel generators, make energy costs volatile and environmentally damaging. In addition, misalignment between solar generation and demand often leads to low self-consumption and energy losses through curtailment. Together, these factors increase operating costs and limit progress toward sustainability goals.

JA Solar’s BESS solution addresses these issues through a set of advanced capabilities. The system supports both AC and DC coupling and enables multi-parallel Power Conversion Systems of up to 3MW. It allows rapid switching from grid-connected to island mode within 20ms using PQ and VF control modes, ensuring uninterrupted power to critical loads during grid outages. A site-level Energy Management System coordinates PV systems, storage units and generators to optimise energy dispatch. This significantly reduces diesel usage while maintaining stable power supply. The black start function enables autonomous system recovery and energy reconstruction, allowing fast restoration following outages.

The benefits are both immediate and wide-ranging. The integrated PV storage generator architecture improves power reliability and overall system stability, reducing the impact of grid failures and load shedding. Energy storage enables peak valley arbitrage, allowing users to store lower-cost energy during off-peak periods and use it during peak demand. This can cut electricity costs by 6 to 12% while lowering reliance on costly backup generation. By smoothing renewable energy fluctuations, the system increases solar self-consumption and reduces curtailment losses.

Safety is a key pillar of the solution. JA Solar applies rigorous battery cell screening, with multi-dimensional selection and testing processes. Multi-layer protection combines electrical, structural and explosion-proof measures, supported by a three-level fire protection design. The company reports zero safety incidents, reflecting a strong safety record. From a cost perspective, the integrated PV storage generator control system optimises total energy expenditure, with low auxiliary consumption, high overall efficiency and a modular design that simplifies operation and maintenance.

Reliability is further reinforced through seamless grid-connected and off-grid switching, black start capability and strong resistance to environmental and electromagnetic interference, supported by an isolated transformer. JA Solar also offers one-stop service and full lifecycle intelligent operation and maintenance support to ensure long-term system performance.

The solution is available across multiple models, including JAP-100kW, JAP-150kW, JAP-250kW, JAG-500kW and JAG-1000kW. Nominal AC power ranges from 100kW to 1000kW, with nominal currents between 144A and 1445A. All models operate at a nominal voltage of 400V with a voltage range of 320 to 460V and a frequency of 50 or 60Hz. Power factor adjustment ranges from 1.0 leading to 1.0 lagging, with overload capacity of 110 percent long term and 120 percent for one minute. On-grid and off-grid switching is completed within 20ms.

PV integration is optional, with MPPT trackers ranging from two on smaller systems to sixteen on the JAG-1000kW model. MPPT rated power spans from 150kWp to 1200kWp. Battery systems use 3.2V 280Ah LFP cells, with configurations from 1P240S to 10P240S and nominal energy capacities from 215kWh to 2150kWh. All systems feature IP54 protection, intelligent air cooling and operation at altitudes up to 2000m, with derating above this level. Fire suppression uses aerosol systems for smaller units and HFC-227ea for larger models, while EMS communication is supported via RS485 and TCP/IP. MPPT and battery configurations can be customised to meet project-specific requirements.

JA Solar’s BESS solution demonstrates a future-ready approach to C and I microgrids, combining safety, efficiency and resilience.

Hybrid microgrids disrupting mining energy economics (Image source: Adobe Stock)

Emissions cuts matter as much as ore grades in an era defined by energy security and climate accountability, according to Etienne le Roux, business development manager – mining at Aggreko.

Here, he examines the value of hybrid microgrids in resolving costs, energy expectations and climate compliance:

Working with mining companies across Africa and other remote regions, Aggreko sees firsthand how hybrid microgrids are reshaping the economics, resilience and climate performance of modern mining operations.

Hybrid power is emerging as one of the fastest environmental, social and governance (ESG) and financing wins in the mining sector. It cuts emissions and costs effectively while mitigating energy security risks, improving an organisation’s bankability and investor appeal.

These hybrid microgrids have the potential to reduce diesel consumption at remote mines by as much as 40-60%, which translates into millions in annual fuel savings and operating costs. And the decarbonisation gains from hybrid microgrids increasingly matter as much as ore grades as lenders, equity investors and stakeholders screen projects and spend on both financial returns and credible transition pathways.

In today’s investment environment, emissions performance has become inseparable from project value. In Africa, mining is entering a decisive new phase because the global energy transition has made it strategically unavoidable to prioritise ESG. The irony is that many of the deposits essential to this transition are isolated, far from national grids, making it challenging for companies to maintain reliable power.

The power systems enabling the supply of future-facing minerals are often anchored in diesel, which has been the default solution for decades as it’s mature, reliable and can be rapidly deployed in modular blocks, allowing for production to start quickly in remote locations.

However, today’s diesel reality carries high costs, volatile fuel logistics and increased scrutiny as a major contributor to Scope 1 emissions. The economics of energy, the tightening expectations of investors and lenders, and the growing influence of downstream buyers who now care how minerals are produced are also putting pressure on companies to change their energy approaches. Energy decisions are no longer operational alone; they are financial, reputational and strategic.

The financial exposure of diesel is also a challenge, particularly when operating off-grid. Every litre has to be trucked, piped or shipped to a site across insecure or poorly maintained transport networks, adding layers of cost and operational risk. Delivered fuel prices at remote EMEA sites frequently exceed international benchmarks once the costs of transport, security and handling are added – the World Bank study found that the cost of diesel and petrol for generators is around $40-$50bn a year at $0.40 to several dollars per kWh in remote locations.

The hybrid microgrid is a strategic step away from this reliance. Designed to integrate solar generation, battery storage and flexible thermal assets under advanced control systems, hybrid microgrids allow mines to displace significant diesel volumes without compromising reliability.

Hybrid solutions have also gained momentum because the economics of renewables have changed measurably over the past few years. Utility-scale solar costs in many parts of Africa have fallen below $0.08 per kWh, with some competitive procurements achieving prices as low as $0.05 per kWh[2][3]. The challenge is no longer cost; it is how to deploy and optimise these assets while maintaining uninterrupted operations.

As a result, this integration quickly becomes an essential part of a mine’s investment profile. Mining’s license to operate increasingly relies on demonstrating that ESG responsibility, and Scope 1 emissions are being adopted into due diligence. Emissions reduction is becoming a signal of management quality, long-term risk control and resilience, which is why mines that reduce diesel dependence are gaining improved access to sustainability-linked finance and preferential terms for offtake agreements.

A mine’s power strategy can strengthen or weaken its financing narrative, and hybrid microgrids offer one of the fastest ways to show measurable progress. Importantly, this transition is not theoretical. Working with mines across Africa, Australia, Europe and the Middle East, Aggreko has deployed hybrid microgrids that deliver immediate cost savings alongside improved reliability and lower emissions.

Aggreko has demonstrated savings of up to 40% compared with diesel-only systems, offering mines both cost stability and decarbonisation within credible and reliable energy infrastructure. With advanced controls and built-in redundancy, hybrid microgrids can achieve more than 99.9% uptime. For emissions, a typical mid-sized mine can save 50,000–100,000 tonnes of CO₂ annually, improving its carbon footprint in a way that is visible and auditable.

This transition isn’t frictionless, however. Financial and capital allocation constraints, regulatory complexities, security and supply chain risks, as well as limited expertise to manage hybrid systems, make it a careful and strategic investment. This is where working with an experienced energy partner becomes critical.

Aggreko is a practical partner for mines trying to navigate this move, offering flexible commercial models such as PPAs and OPEX-led structures alongside rapid deployment with modular systems and the ability to optimise thermal assets while layering in solar and battery storage. Aggreko is the step between, bringing the expertise and the solutions into a simplified solution that makes it easier and faster for companies to benefit.

This is the pivot facing Africa’s mining sector now. Mines can remain dependent on high-cost, carbon-intensive diesel generation, or transition to hybrid microgrids that provide reliable, low-carbon energy at lower cost. And because hybrid microgrids simultaneously address cost, emissions, reliability and investor confidence, they represent one of the few interventions capable of unlocking multiple benefits at once, rather than incrementally.

Renewable energy and infrastructure propel MENA's SAF growth

The Middle East and North Africa (MENA) region could emerge as a global leader in sustainable aviation fuel (SAF) production and trade, according to a new white paper examining the region’s feedstock, infrastructure and policy advantages.

While SAF production is currently concentrated in Europe and North America, the paper, published by the SAF MENA Congress, argues that MENA has a unique opportunity to scale both biobased and synthetic fuels at pace, driven by abundant renewable energy, established hydrocarbon infrastructure and strong domestic aviation demand.

A central pillar of this potential lies in synthetic SAF, produced via power-to-liquids (PtL) pathways using green hydrogen and captured carbon dioxide. The region benefits from some of the world’s highest solar irradiation levels and growing wind capacity, enabling access to low-cost renewable electricity. This, combined with large-scale electrolysers and emerging carbon capture infrastructure, positions Gulf states in particular as highly competitive producers of e-SAF.

Unlike many regions facing land constraints and grid congestion, MENA can deploy renewables at scale and co-locate projects with industrial hubs, export terminals and aviation infrastructure. The paper highlights that existing refining, storage and pipeline assets can be repurposed for SAF, reducing costs and shortening project timelines.

The report also challenges assumptions that the region lacks viable biobased feedstocks. Urban waste, used cooking oil, animal fats and agricultural residues are identified as underutilised resources, particularly in Egypt and Turkey. In addition, desert-adapted biomass such as algae, halophytes and wastewater-grown crops could provide non-competitive feedstock options suited to arid climates.

Geography is another strategic advantage. Situated at the crossroads of Europe, Asia and Africa, MENA already hosts some of the world’s busiest aviation hubs. Short shipping distances, established fuel trading ecosystems and high volumes of long-haul refuelling make the region well placed to become a global SAF bunkering and export centre as international mandates tighten.

Policy alignment and access to sovereign capital further strengthen the region’s position. Several governments have adopted net-zero targets, hydrogen strategies and state-backed aviation offtake, creating conditions for large-scale investment and accelerated deployment.

The white paper concludes that SAF leadership will be determined not by technology alone, but by scale, cost and speed. With rising global demand and regulatory pressure, the question is no longer whether MENA can play a major role in aviation decarbonisation, but how quickly it chooses to do so.
