A growing wave of concern has emerged in the United States after American cybersecurity experts discovered hidden cellular communication components embedded in Chinese-made solar inverters installed across solar farms in the country.
In May of 2025, U.S. experts found undocumented communication modules and secret radios embedded in some Chinese-manufactured solar inverters and battery systems. Not listed in product documentation, these shadow components create hidden backdoors that can circumvent utility firewalls and allow remote access to the devices.
If not, China will continue to evade state-specific bans, with new vulnerabilities capable of emerging from wherever inverters are produced next. Undocumented radios found in Chinese-made solar inverters pose a threat to U.S. energy infrastructure and security, enabling disruption of critical systems.
Over 200 gigawatts of European solar capacity (equivalent to more than 200 nuclear power plants) are tied to Chinese-made inverters. In November 2024, Lithuania passed a law effectively blocking remote control of energy installations by unfriendly foreign states—a de facto restriction on Chinese inverters above a certain size.

We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology. The reason is related to the intrinsic qualities of lithium-ion batteries but also linked to lower transportation costs.
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
In summary, the total cost of ownership per usable kWh is about 2.8 times cheaper for a lithium-based solution than for a lead acid solution. We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology.
As expected, on a $/kWh basis, longer duration batteries have a lower capital cost, and on a $/kW basis, shorter duration batteries have a lower capital cost. Figure 7 also demonstrates why it is critical to cite the duration whenever providing a capital cost in $/kWh or $/kW. Figure 7.
