Solar Energy: Photovoltaics and Thermal Systems is a concise, practice-oriented guide to harvesting the sun for power and heat. It links fundamentals to real-world design: solar resource assessment; PV cell/module physics; MPPT, inverters, batteries and balance-of-system; plus solar thermal collectors, CSP, heat transfer and thermal storage. Readers learn sizing workflows for rooftop, off-grid, microgrid and hybrid PV–thermal (PVT) setups, with reliability, O&M, safety, and codes/standards built in. Economic evaluation (LCOE/payback), case studies, and solved examples make this an ideal text for students, engineers, and energy planners seeking efficient, bankable solar solutions.
