Each satellite will be outfitted with a 33-square-foot reflective Mylar mirror. These mirrors are designed to reflect sunlight down to Earth, targeting <keyword id="20658734" type="General" weightage="20" keywordseo="solar-farms" source="keywords">solar farms</keyword> and extending their operational hours by providing an extra 30 minutes of sunlight after sunset or before sunrise. The mirrors will focus sunlight into a concentrated beam, directed by solar farm operators using a simple interface, where users can log in, provide GPS coordinates, and request sunlight.<br /><div type="twitter" handle="bennbuilds" handlename="bennbuilds" favoritecount="0" retweetcount="0" id="1826682383514697993"></div>The idea is to make solar energy more available when it’s most needed — not just during daylight hours, but also in the early morning and evening when electricity demand is typically higher. This could potentially increase the efficiency and profitability of <keyword id="20423867" type="General" weightage="20" keywordseo="solar-power-generation" source="keywords">solar power generation</keyword>, as energy produced during these periods can be sold at higher rates.<br /><h3 style="line-height:1.2;margin-top:14pt;margin-bottom:4pt;">Potential challenges</h3>Despite the excitement around this technology, there are several challenges that Reflect Orbital will need to overcome. Weather conditions such as thick clouds or storms could obstruct the reflected sunlight, limiting its effectiveness. Seasonal changes that affect the angle and duration of sunlight might also present difficulties. Additionally, the potential environmental impact, including light pollution and interference with astronomical observations, has raised concerns among scientists and environmentalists.<br /><div type="Article" hostid="261" msid="112805908" title="How will Sunita Williams’ body have changed when she returns from space in February 2025?" mstype="2" mssubtype="0"></div>Reflect Orbital is aware of these challenges and has designed the mirrors to minimise light pollution. The company has also tested its technology using a hot air balloon, which successfully simulated the satellite mirrors' effect by reflecting sunlight down to a solar farm. According to co-founder <keyword id="22948422" type="General" weightage="20" keywordseo="ben-nowack" source="keywords">Ben Nowack</keyword>, the company was able to generate "500 watts of energy per square metre" of solar panel, which is about "half the brightness of the sun."<br /><div type="twitter" handle="bennbuilds" handlename="bennbuilds" favoritecount="0" retweetcount="0" id="1767961251186163857"></div>Reflect Orbital is still in the early stages, with plans to launch its first test satellite in 2025.
