Creative thinking for vertical east-west bifacial PV projects

A Finnish-Norwegian research group has assessed the global potential of vertical east-west bifacial PV (VBPV) projects and found that these installations may provide a low LCOE at Nordic latitudes, in Central Europe and subtropical desert areas. The researchers also found that residential and commercial VBPV systems are a grid-friendly solution for low-voltage networks when compared to monofacial arrays.

‘Residential batteries are less profitable than selling excess power to the grid’

Although self-consumption of solar power is the optimal economic approach, the expense of household batteries at present outweighs the increased ability they offer to use electricity generated on the roof. Whether aggregated ‘virtual batteries’ offer better returns is an open question, due to lack of electricity company transparency.

Photovoltaics and geothermal heat pumps for domestic hot water heating

According to a new study from LUT University, domestic water heating costs may be reduced by combining rooftop PV with geothermal heat pumps. Scientists developed a control method to minimize these costs by taking advantage of cheap spot market electricity and maximized PV power generation, as well as considering heat demand, PV generation forecasts, and heat pump efficiency.
