Europe can compete effectively with Asian solar manufacturers with innovative long-term PV technology solutions

The world's energy sector is concentrated in solar, wind, electricity transmission/distribution and hydroelectric power. For example, investment in solar power plants alone is higher than investment in natural gas, coal-fired and nuclear power plants combined. This is encouraging, but another fact is worrying: China's exports of solar modules to Europe in the first four months of 2022 were 2.5 times higher compared to 2021. In April alone, nearly 8 GW of solar modules worth more than €2 billion were imported from China into Europe.

Uzbekistan is steaming ahead in the race to carbon neutrality

The war in Ukraine continues to disrupt the global energy sector and, combined with the recent heatwaves affecting Europe, the need to restructure economies is starker than ever. Luckily, there are some countries that have kept working on their energy transition reforms and taking tangible actions towards tackling climate change. Uzbekistan is one of them.

Considerations for solar projects during heat waves

High temperatures can affect different components of PV systems. Inverters can fail, the efficiency of solar modules can decline, and existing cell damage can become worse. However, investors, planners, and operators can adjust to heat waves in a number of different ways.

Italy publishes new national guidelines for agrovoltaic plants

On June 27, the Guidelines for The Design, Construction and Operation of Agrovoltaic Plants were published in Italy by the Ministry of Ecological Transition, in coordination with the Council for Agricultural Research and Analysis of Agricultural Economics (CREA), Gestore dei Servizi Energetici S.p.A. (GSE), the National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA), and Research on the Energy System S.p.A. (RSE). From now on, developers and, in general, RES plant owners will have to consider the principles herein outlined, to have their plants classified as agrovoltaic.

Rays of solar hope for Europe: A Midsummer reflection

For centuries, cultures in Europe have marked their calendars to celebrate Midsummer and the Summer Solstice. Traditionally a time to enjoy bright evenings, and the light and hope of the sun, the Summer Solstice falls on June 21. On the longest day of sunlight in 2022, Europe has much to hope for. After difficult pandemic years, enduring cost of living and energy price hikes, and the on-going, unprovoked, Russian war on Ukraine, Midsummer gives us a small moment to reflect on, and hope for, brighter times ahead.

As EVs drive off with Li-ion supply, the push to stationary storage alternatives accelerates

The throes of a lithium shortage are increasingly upending long-term supply strategies and stoking demand for alternative technologies for stationary energy storage projects.
