rooftop solar

Svea Solar solar parks managing director Pieter Godderis said the company was ‘really proud’ of the landmark deal with Scandanavian dairy titan Arla, which stipulates the Swedish independent power producer will provide the multinational 100 GWh of solar annually for a decade.

Scientists in China have outlined a new system architecture for vacuum integrated photovoltaic (VPV) curtain walls. They claim the new design can reduce building energy consumption and yield more surplus power generation electricity.

Swisspower-Stadtwerk SIG says its pilot solar bicycle path in Satigny will pave the way for similar projects in Switzerland.

UK roofing specialist SIG Building Solutions is offering the solar carport solution in three different versions. The largest structure is designed to give maximum power for east-west facing double row car parking layouts.

The latest figures from French grid operator Enedis for the connection of new PV systems under France’s solar self-consumption scheme reveal significant market growth in the first half of 2023.

A Swedish research group has found that using deep machine learning to identify solar energy systems in aerial images may not be so accurate in non-densely populated countries such as Sweden. They have also found, however, that this technique may be trained via an iterative process and achieve satisfying results.

The lower the uncertainty in solar resource data, the lower the investment costs. IEA PVPS Task 16 has organized and published two benchmarks to make uncertainty of models and data comparable – a first important step. The benchmarks included modeled solar resource data and methods to fill gaps in measurements.

Multiple factors affect the lifespan of residential battery energy storage systems. We look at the lifespans of batteries in the third part of this series.

Octopus Energy has developed new residential heat pumps, with plans to initially market a 6 kW version, followed by larger models in the near future. The UK-based company makes the heat pumps at its facility in Craigavon, Northern Ireland.

Johnson Controls-Hitachi Air Conditioning has developed a residential dual fuel heat pump system that combines an air source heat pump and a gas furnace. The manufacturer says the furnace is designed to ensure there is no compromise in heating performance, even when temperatures are extremely low.
