A Shenzhen Tramsmart was present at the event with a launch of the WalkingBoy, a 2.1 kg lithium iron phosphate (LiFePO4) battery with 153.6 Wh capacity. It can be charged using a solar panel or directly from the grid.
World installed 536 GW of renewables in 2023
According to the last REN21 Global Status Report 2024, presented at the fair, last year alone 536 GW of renewable energy capacity were installed worldwide. Of this total, 407 GW were photovoltaic energy, showing that solar sources play a central role in the expansion of renewables.
In evaluating Rana Adib, Executive Director of REN21, The smarter E Europe offers the necessary space to share ideas about current trends, technologies and business models
“This requires long-term collaborative planning involving all sectors and stakeholders, along with investments in the grid and storage infrastructure needed to unlock greater shares of renewable energy across the economy,” he commented.
Forecasts for installations around the world
O Solar Channel spoke to InfoLink Consulting, which reported that the world should install around 500 GW of solar source power, in 2023 this figure was 447 GW.
Around 50% of these 500 GW should be in China, followed by the United States with 38GW to 42 GW, India should add 20 GW to 25 GW, and Brazil and Germany should fight for fourth position.
Furthermore, the market should remain stable in relation to 2023 and should not experience major growth. A scenario that should be repeated in 2025, growth, if any, of the order of 3%.
Charger for electric vehicles with more efficiency and speed
A Siemens, a company specializing in industrial automation and software, infrastructure, building technology and transport, was also present at Intersolar Europe 2024, presenting a novelty for electromobility: the most dynamic SICHARGE D charger for eCars and eTrucks from 160 kW to 400 kW.
