marianaproenca / Unsplash</small> </figcaption> </figure> <p>Photovoltaic thermal (PVT) systems directly convert sunlight into both electricity and thermal energy, making them more than 70% efficient than standalone photvoltaics.</p> <p>The team at Nottingham has used a computer model to study a PVT system with wavy pipes. It was found to work more effectively and also keeps solar panels at an optimum temperature, resulting in higer electricity generation.</p> <p>The wavy tube PVT system captured more than 85% of thermal energy received in the model, whereas the straight ones are only 72% efficient.</p> <p>The researchers measured metrics like the shape of the pipes, the speed of fluid, the size of panels, how well the system works and how much energy was generated.</p> <p>Dr Surojit Sen, from the Power Electronics, Machines and Drives research group, believes, 'Humans spend about 15% of all energy usage, about 600 billion gigajoules, on indoor heating only. It is crucial to rapidly move over to cleaner energy sources and what better than the sun.'</p> <div class="resource-detail-tags"> <h4>Related topics</h4> <div class="resource-detail-tags-list"> <a
