Residential PV

In a sales environment where only one in 10 viable solar projects moves forward, getting from a good idea to a firm decision by a customer needs to happen fast. Here’s how one commercial solar installer makes technology work.

Scientists in the United States have analyzed how semitransparent organic solar cells placed on the roof of a greenhouse may impact crop production. They assessed, in particular, how solar power generation may affect lettuce crops and found that the plants not only grow unhindered but also that the solar cells reduce overheating in the greenhouse.

The search for power system security has sparked an Australian first with the Australian Energy Market Operator (AEMO) confirming South Australian energy authorities switched off 67 MW of rooftop and large-scale solar PV at the weekend when electricity demand plunged to a near-record low.

Renewable electricity will be linked to 90% of the actions needed to remove carbon emissions in 2050, according to the International Renewable Energy Agency, and the biggest volume of generation capacity will be provided by solar.

Researchers in Spain have compiled a list of key performance indicators intended at evaluating not only the quality of a heat pump or a PV generator; but also the quality of their integration. pv magazine spoke to research co-author Celena Lorenzo about the potential and challenges of this combination. According to her, heat pumps powered by PV alone are efficient enough for both cooling and heating.

Battery storage manufacturer RedEarth has partnered with a major Australian housing developer to offer new-home buyers solar and solar/battery systems tailored to their needs from the get go – and with the opportunity to sell excess energy at optimized prices where the grid needs it most.

Distributed solar and storage should be the focus for $9.6 billion in FEMA funds allocated for Puerto Rico’s grid reconstruction, says a new report based on independent analysis.

The Eastern European country is expected to add around 2 GW per year over the next five years, according to Polish research institute Instytut Energetyki Odnawialnej. By the end of 2025, its cumulative installed PV capacity should reach 14.93 GW.

Rooftops will have to supply a third of the 524 GW of solar generation capacity needed by 2045 to reach a zero-carbon economy by mid century, according to an academic paper. The researchers also suggested green hydrogen should not play a central role in the nation’s energy transition.

The virtual battery records the surplus solar power injected into the grid on sunny days and returns it at night or in winter. If the production of the PV plant is not sufficient to cover all the electricity needs, MyLight Systems provides the household with green energy supplied by Swiss energy company Axpo.
