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.

Vanessa Nakate shocked organisers of the Berlin Energy Transition Dialogue by delivering a speech highlighting how she and a fellow youth activist had to submit their presentations for approval in advance of the event and were banned from criticising any of the politicians involved.

Tensions are heating up throughout the world over the issue of forced labor. Calls are increasing for supply chain transparency, and recently published EU draft legislation on corporate due diligence and accountability should improve upon the currently available voluntary measures, which have been described as largely ineffective. With this in mind, pv magazine’s UP Initiative will spend the second quarter of 2021 looking at what solar and energy storage companies can do to lead by positive example when it comes to the workers who are involved in the production of their products and services.

Enhanced module appearance and power output can be achieved by a smart cell interconnection technique Longi is employing in its Hi-MO5 module series. But as with all new technologies, there are potential pitfalls.

Lithium-ion batteries can not only improve self-consumption in commercial PV systems but are also able to efficiently perform peak shaving and price arbitrage, according to an international research group which has proposed a new strategy to calculate the best system configuration in terms of costs and revenue. The scientists specified, however, that the novel strategy may become effective only if storage system prices will drop under $250/kWh.

Not all rooftops can bear the weight of glass PV modules. Some others have curves and shapes ill-suited to uniform, bulky panels. Flexible modules have long been advanced as the solution here, however the keys to unlocking this potential have proven elusive.

Both solar and the farming industry are beginning to see potential in the combined use of land for food production and energy generation. And as innovators begin to experiment with different forms, it’s becoming clear that in most cases it is solar that will have to bend to the needs of agriculture, and not the other way around, to ensure a positive outcome.

Dutch scientist Bonna Newmann spoke with pv magazine about the present and future of vehicle-integrated PV from a technological and economic perspective. Solar panels installed on cars could have a payback time of only three or four years and ensure 10,000 km of pure PV-generated road travel per year, she said. Furthermore, if you live in a sunny place, you can drive an electric car with solar panels for weeks during summertime, without the need for recharging, she pointed out.

A new report from the U.S.-based analyst predicts that new PV additions for 2021 may range from 163 to 221 GW next year and from 179 to 240 GW in 2023. According to BloombergNEF, the current supply bottlenecks for glass and polysilicon will unlikely halt the global PV market.

Scientists in Germany have estimated that roof and facade PV systems can cover almost 40% of the total requirements of a standard office building, assuming that no battery storage is installed.
