Efficient rooftop solar+storage without MPPT

A German research group is trying to determine whether the combination of solar and storage with direct coupling and without the aid of maximum power point tracking (MPPT) electronics is feasible. According to its findings, this particular configuration might be efficient, but it will likely require special panels and batteries.

Shielding PV against Earth’s magnetic field

Researchers in Kenya are seeking to reduce the influence of the Geomagnetic field on PV panel performance by replacing aluminum module frames with a steel cage. They have specified they have been unable to quantify costs related to the solution, and that more research is needed.

Italy’s largest PV project comes online

A 103 MW solar park built by Danish developer European Energy has been connected to the grid after a year of construction work. The project had been started in 2011 and at one stage appeared doomed, when a national feed-in tariff program ended.

Heterojunction MWT solar module based on 23%-efficient cells

Scientists in the Netherlands have claimed that a heterojunction metal wrap-through solar module they are designing could offer a 4% performance improvement over conventional heterojunction panels.

Self-cleaning PV system with active cooling tech

An international research group has developed a self-cooling PV system featuring a 250 W 60-cell polycrystalline module and a thermal collector attached to the back side of the panel. The cleaning tech is based on a microcontroller programmable integrated circuit, which controls a rotating DC motor.
