131 Mobile and quickly assembled renewable energy modules, which can be quickly deployed in humanitarian crisis zones, play a particularly important role. Such systems are already being used to power hospitals, heating centers, and volunteer hubs, ensuring uninterrupted access to electricity in emergency situations. This example clearly demonstrates that renewable energy can enhance the resilience of communities in difficult wartime conditions. Furthermore, investments in RES help reduce dependence on energy imports, which is especially important under wartime conditions. The ability to generate electricity locally from renewable sources reduces the risk of energy blackmail and makes the country more energy independent, which is crucial for national security. Overall, the war has become a catalyst not only for rethinking Ukraine's energy policy but also for accelerating the transition to sustainable, safe, and environmentally friendly energy sources. Under these circumstances, renewable energy not only supports the population's essential needs but also serves as the foundation for the future development of the energy sector, taking into account new security and climate challenges. Ukraine's climate is favorable for the development of solar energy—annual insolation ranges from 1,070 to 1,400 kWh per square meter, creating substantial potential for the deployment of solar power plants. However, their construction requires large land areas, which is one of the challenges in the large-scale implementation of this technology [3]. Solar energy is becoming an increasingly important component of modern energy systems. Concentrated solar power (CSP) technologies allow solar energy to be stored and used even at night. Amid the ongoing war in eastern and southern Ukraine, a substantial share of industrial solar installations has been damaged by hostilities. Estimates indicate that up to 50% of the installed capacity in these regions has been destroyed or taken out of service, significantly impacting the country's energy stability [6]. The private sector has also sustained significant losses - about a quarter of private solar power plants in active combat zones have been damaged. In addition,
