To pursue a career in solar panels and renewable energy, it's essential to choose the right educational path. Focusing on physics or mechanical engineering is advisable, with an emphasis on physics and mathematics for undergraduates, especially for those interested in research. Renewable energy typically falls under geophysics, while solar energy is more aligned with electrical or materials engineering and solid-state physics. It's important to explore universities that offer relevant postgraduate programs and review their prospectuses. Additionally, in the UK, there is a notable center for doctoral training in new and sustainable photovoltaics, supported by a collaboration of prestigious universities. This could provide valuable opportunities for research and specialization in the field.
