How can the inverter manage high-temperature conditions effectively

As the scorching summer approaches, it’s common for users to assume that the intense sunlight will lead to higher power generation in photovoltaic power stations. However, the reality is more nuanced. The power output of a photovoltaic system depends on various factors, with irradiance and ambient temperature being among the most crucial. While summer brings …

New MPPT technique based on improved snake algorithm

A group of researchers from Lanzhou Jiaotong University in China has developed a maximum power point tracking (MPPT) technique based on an improved snake optimizer (ISO) algorithm. The ISO is a swarm-intelligence-based optimization algorithm proposed in 2022 to improve the typical shortcomings of the snake algorithm. The latter is inspired by the behavior of snakes …

PV, storage may allow 53% of European households to end reliance on grid

Thanks to PV systems and battery storage, millions of households in Europe are already partially self-sufficient. A German-Swiss research group has calculated the potential for European residential buildings to achieve grid independence with solar-plus-storage solutions. The team aimed to determine whether such homes could abandon the grid completely. They based their calculations on a database …
