From pv magazine GermanyAnyone who walked through the halls of Intersolar Europe in Munich with their eyes open could discover, in addition to standard module technologies such as Topcon and heterojunction, double-sided and with back contacts, other modules that are not in line with the mainstream and are currently waiting for a breakthrough.

From pv magazine GermanyAfter a sunny winter day, an electric vehicle and home battery may be fully charged. However, overnight, the storage capacity in the house decreases, forcing the operator to draw power from the grid despite unused solar energy. Many EV owners seek bidirectional charging, or vehicle-to-home (V2H), but it has not yet become standard. Today, many EVs can connect to small appliances, such as a vacuum cleaner or camping stove, via a 230 V socket.

From ESS NewsDegradation of individual battery cells is a driver in BESS losing storage capacity over time. Small differences in quality, which initially seem minimal, gradually increase and since the cells are connected in series, and can only be charged and discharged together, if one fails, it affects the performance of the entire string. With regular balancing coming at the expense of efficiency, systems that do not require an external inverter are attractive.

From pv magazine GermanyPaxos Solar, a German building-integrated photovoltaic (BIPV) specialist, has developed a new solar tile that not only generates power but also produces heat for heat pumps. The tile is a small glass-glass module measuring 59.5 cm x 48 cm and delivering 44 W of output. About 4.3 tiles would be installed per square meter, providing a total output of 190 W. The modules feature highly efficient back-contact cells from China’s Longi.
