When the grid goes down, most solar systems that lack a battery will also shut down. But with batteries, a home can disconnect from the grid. Each day, the sun powers the home and charges up the batteries, which provide power through the night. Our team atBerkeleyLab explored what it would take for homes and
One of the oft-heard criticisms of electric vehicles (EVs) is that, although they may be zero emission at the tailpipe, millions of tonnes of CO2 is created during the generation of their energy. While there is some truth in this given that huge amounts of fossil fuels are burnt by power stations, an increasing amount
The government has confirmed that homes with flat roofs can now install solar photovoltaic (PV) panels without planning permission. As part of the confirmation, the government also removed the 1MW capacity restriction, which required businesses to apply for planning permission if its solar panels were to generate over 1MW of electricity. Announced by the
Solar electricity panels, also known as photovoltaics (PV), capture the sun’s energy and convert it into electricity that you can use in your home. By installing solar panels, you can generate your own renewable electricity. How do solar panels work? A solar PV panel consists of many cells made from layers of semi-conducting material, most commonly silicon. When light shines on this
Just over half of Europe's single family homes could technically be fully energy self-sufficient with a combination of solar energy and storage systems, according to a report by the Karlsruhe Institute of Technology (KIT). Already today, 53 percent of about 41 million buildings included in the analysis could theoretically go off-grid and have a fully
The Energy Act 2023, which has been called the “biggest piece of energy legislation in the UK’s history”, received Royal Assent yesterday (26 October). The Act, which has now become law, includes a number of major changes aimed at creating a more efficient energy system that can uphold the growing number of electrified technologies being
Renewables are set to contribute 80% of new power capacity to 2030 in the stated policies scenario (STEPS), with solar PV alone accounting for more than half of this, according to the International Energy Agency (IEA). In its flagship World Energy Outlook report, the IEA expects solar manufacturing capacity to exceed 1.2TW of module nameplate capacity
Fossil fuel-powered generators are strapped with emission concerns, maintenance needs, and potential personal risk, whereas a battery-based energy storage system is safe, efficient and has a very low operating cost. We are living in an era of extreme weather, and there is no end in sight. In July 2023 alone, there were devastating wildfires in
The UK has installed more solar power systems in 2023 than in all of 2022, according to data from the Microgeneration Certification Scheme (MCS), which accredits PV, wind and micro-CHP installations up to 50kW. Trade body Solar Energy UK (SEUK) said the data showed a new annual record for 2023 with 138,336 solar PV installations since
The cost of solar power has fallen by 87%, and battery storage by 85% in the past decade, according to a new study – here’s why. Berlin-based scientific think tank Mercator Research Institute on Global Commons and Climate Change (MCC) has released a new study in the journal Energy Research & Social Science in which the researchers compared
