New control strategy for PV-powered water pumps operating under variable atmospheric conditions

Scientists in Turkey have developed a new algorithm to optimize the efficiency of PV-powered water pumps. The novel technique is based on the Extended Kalman–Bucy filter, which is a predictor-corrector algorithm used extensively in control systems engineering for estimating unmeasured states of a process.

PV-powered heat pumps with thermal, electrical storage

Italian researchers have looked at the potential of thermal and electrical energy storage to improve self-consumption rates in buildings when coupled with PV-powered heat pumps. They have concluded that such an approach could yield self-consumption rates of more than 80%.

New bio-inspired based algorithm to improve PV output under partial shading

The novel algorithm is based on the behavior of marine animal tunicates and reportedly provides remarkable results in terms of power errors. It was tested in four PV system configurations with five different shade patterns.

Israel’s Teralight secures 23-year PPA for 108 MW/433 MWh of solar, storage

Teralight has signed a 23-year power purchase agreement (PPA) for 108 MW/433 MWh of solar-plus-storage capacity. It will sell electricity to Dalia Power Energies under a tariff linked to the Israeli Electricity Authority’s regulated production tariffs.

Underground photovoltaic water pumping system with average system efficiency of up to 8.5%

Developed by Egyptian scientists, the PV-powered water pumping system may produce up to 181.8 m3 of water per day. The system consists of two PV arrays with each a capacity of 4.6 kW and a pumping unit made up of a 7.5 kW three-phase alternating current motor, a multistage submersible pump, a deep well, and a 15 kW inverter.

Heat pump design to reduce footprint of solar thermal installations

A US-Mexican research team has investigated how linking heat pumps with solar thermal collectors may help reduce the surface needed to deploy the collectors themselves. The scientists found the proposed solution may not only significantly reduce the footprint of solar thermal systems but also provide a lower levelized cost of energy compared to fossil fuels.

Solegreen to deploy 210 MW/470 MWh of solar-plus-storage in Israel

Solegreen plans to deploy 210 MW/470 MWh of solar-plus-storage in Israel, through a project selected by the Israeli authorities in a 2020 tender. The facilities will sell power at ILS 0.1715 ($0.0459)/kWh.

Scientists analyze seasonal performance of rooftop, vertical PV in the Arctic

New research from Finland shows that the best season for rooftop PV generation in the Arctic is spring, and that the best tilt angle for rooftop systems is 28 degrees. It also showed that vertical PV installations perform better in winter.
