INTRODUCTION

As humanity sets its sights on expanding beyond Earth, the demand for sustainable, reliable and efficient energy systems becomes increasingly critical. Solar energy, with its abundance in space and compatibility with emerging technologies, stands as the most promising solution. The energy needs of space colonization are immense and solar power provides an ideal, renewable and almost limitless resource, especially given the continuous exposure to sunlight in extraterrestrial environments. Decentralized energy management systems can autonomously adjust to dynamic environmental conditions, ensuring continuous power supply, even in the most challenging extraterrestrial environments. Recent advancements in microgrid technologies and their applications in remote settings offer valuable insights for designing such systems for space [1].

Solar energy in space involves harnessing the Sun’s abundant and unobstructed energy beyond Earth’s atmosphere. Solar energy in space typically refers to collecting sunlight using solar panels on satellites or space-based platforms and converting it into usable power, either for space missions or to transmit back to Earth. Unlike Earth-based solar energy, space-based systems avoid atmospheric interference (clouds, dust, weather) and the day-night cycle, enabling near-constant energy generation. Key advantages include continuous exposure, as the Sun is always visible in space (outside of specific orbital shadows), providing a steady energy supply; higher intensity, with solar radiation about 35% stronger in space (around 1,366 watts per square meter) compared to the Earth’s surface due to no atmospheric filtering; and scalability, allowing for the deployment of large structures in orbit without land constraints. This process works by using solar panels, where photovoltaic cells, similar to those used on Earth, convert sunlight into electricity, optimized in space for efficiency and durability against radiation; energy transmission, where for Earth use, energy is converted into microwaves or lasers and beamed wirelessly to ground stations, where it’s reconverted into electricity; and orbiting platforms, with systems like Solar Power Satellites proposed to operate in geostationary orbit (about 36,000 km above Earth) for consistent alignment with receivers. Applications include spacecraft power, with satellites, space stations (e.g., the International Space Station) and and probes relying on solar panels for onboard power; space-to-Earth power, with concepts like Space-Based Solar Power aiming to supply renewable energy to Earth’s grid, potentially meeting large-scale energy demands; and exploration, supporting lunar bases, Mars missions, or deep-space travel where sunlight is still accessible. Challenges include cost, as launching hardware into space is expensive, though declining launch costs (e.g., via SpaceX) are making it more feasible; maintenance, as repairing or upgrading systems in orbit is difficult, requiring robust, long-lasting designs; transmission efficiency, as converting and beaming energy back to Earth involves losses and ensuring safety (e.g., avoiding harm from microwave beams) is critical; and space debris, with orbiting platforms needing to navigate or withstand debris risks. Currently, solar power is standard for satellites and space stations and SBSP remains experimental, with prototypes tested by organizations like NASA, Japan’s JAXA and China, with Caltech’s Space Solar Power Demonstrator successfully beaming power from orbit to Earth in 2023, a major milestone. Future potential includes providing a near-infinite, clean energy source and reducing reliance on fossil fuels, with advances in robotics, wireless power transmission and lightweight materials being key to making large-scale systems viable. In short, solar energy in space leverages the Sun’s raw power in an environment free from terrestrial limitations, with the potential to revolutionize energy for both space exploration and Earth, if we can overcome the technical and economic hurdles.
