Top 10 Trends in Solar Energy by 2025 by Huawei

According to the positive forecasts of IB Center, from 2019 to 2024, renewable energy is projected to increase globally by 50% thanks to solar power, as the PV segment alone accounts for nearly 60% of the expected growth. In Ukraine, solar power capacity has increased more than 7 times in the past 3 years. Thus, as of December 1, 2019, the total capacity of all Ukrainian solar power facilities exceeded 3.8 GW.

Similar positive forecasts were also presented by Huawei. Over the next 5 to 10 years, renewable energy will assume a more prominent role as a main power source for power grids. Solar power, in particular, as the most noteworthy form of renewable energy, has a particularly bright future. However, as renewable represents a greater proportion of total energy production, ensuring safety, reliability, and cost-effectiveness across power generation assets will become the upmost priority.

The rapid development of new IT technologies such as artificial intelligence, cloud storage technologies, 5G development will affect all industries, including the solar industry.

Huawei outlined the major trends in the solar energy industry, which are aimed at bringing the industry to smart, green solutions, as well as providing insight into the innovation and growth of the new energy industry.

The main topic of the 11th International Sustainable Energy Forum SEF 2019 KYIV ( was the topic of digitization in industry. And now Huawei is also reminded that by 2025, 90% of solar power plants will use digital technology. They will help PV plants to be simple, intelligent, and efficient management.

2. AI-driven Smart Upgrades

The in-depth integration of AI and PV will facilitate mutual sensing and interconnection between devices, and will improve power generation and O&M efficiency through collaborative optimization. AI techniques can offer promising new avenues for PV systems, including: proactive identification and protection of PV module and device faults with AI diagnosis algorithms; tracker algorithm optimization with massive plant data and self-learning for higher yields; and AI-aided solar-storage synergy to automatically optimize PV-storage plant revenue. As a result, over 70% of solar plants will use artificial intelligence to optimize and improve the efficiency of the SES.

3. Unmanned PV Plants

Drone inspection and robot-based automatic O&M will handle dangerous and repetitive O&M work that requires a continual high degree of accuracy, for enhanced productivity and safety in PV plants. As is estimated, it is expected that 80% PV plants in the future will be fully unmanned.

4. Proactive Support for Power Grids

The increasing penetration level of power-electronic-interfaced energy will undermine power grid strength, hindering the broader application of PV systems. Over the next 5 years, PV plants must gradually evolve from adapting to the power grid, to supporting the power grid.

5. Energy Storage

The topic of Energy Storage will become one of the key ones at the 9th CISOLAR 2020 International Solar Energy Conference to be held in Kyiv on July 15 (

It is projected that energy storage will work in tandem with PV systems, and become a critical component. Projections indicate that by 2025, the proportion of PV systems with energy storage will exceed 30%.

6. Virtual Power Plants

Over the next 5 years, ICT technologies, such as 5G, blockchain, and cloud services, will be widely applied in distributed power plants, forming VPPs for collaborative management, and participating in the scheduling, transaction, and auxiliary services for power systems. The development of VPP technology will inspire new business models and attract new market players in distributed PV scenarios, serving as an engine of growth for distributed PV. Huawei estimates that more than 80% of households and private SES will connect to virtual power plants.

7. Active Safety

With the broader application of distributed PV, building and personal safety has become a major concern. PV arcing risks caused by the poor contact of nodes in PV modules, poor connections from PV connectors, or aged or broken cables, have become a pressing matter in the industry. To mitigate such risks, AFCI will become a standard function for distributed PV rooftop systems, and will be incorporated into international industry standards.

8. Higher Power Density

With the trend of lower LCOE of solar, there calls higher requirements in higher power of a single module and easy inverter maintenance. To achieve this, higher power density is required. With breakthroughs in research of wide-bandgap semiconductors, such as SiC and GaN, as well as advanced control algorithms, inverter power density is expected to increase by more than 50% in the next 5 years.

9. Modular Design

Inverters, PCSs, and energy storage devices are key components in a PV plant, which greatly affect the availability of the entire PV plant system. As the capacity and complexity of PV plants increase, the traditional, expert-driven approach for onsite maintenance will be too costly. Modular design will become mainstream, as it enables flexible deployment, smooth expansion, and expert-free maintenance, greatly reducing O&M costs and improving system availability.

10. Security and Trustworthiness

The increase in the cumulative capacity of global PV plants, and greater complexity of network architecture, which makes the network security risks of PV plants increasing. In addition, there are more stringent requirements for user privacy and security for distributed PV plants. All these trends suggest that PV plants need to possess security and trustworthiness capabilities in terms of reliability, availability, security, safety, resilience, and privacy.

By presenting these 10 major trends in solar energy by 2025, Huawei plans to play the role in creating a green, intelligent world where the limitless potential of new energy solutions can be widespread in society.

Huawei is a partner and megawatt sponsor of the CISOLAR 2020 - 9th International Solar Energy Conference and Trade Show of Central and Eastern Europe, which will be held on July 15-17 in Kyiv.
