The aviation advanced into a more renewable energy era with attempts to overcome serious hurdles toward its growth. According to IEA, over 940 GW was achieved in solar PV capacity in 2021, whereas in order to achieve the climate goals, this capacity needs to increase at least threefold by 2030. Raw material prices, especially those of polysilicon, are extremely volatile; prices have surged by over 300% in the last five years, which is one major problem facing photovoltaic manufacturing. This spontaneous price adjustment adds uncertainty to the manufacturer-side operations of solar PV, resulting in additional costs to the consumer while also discouraging solar PV deployment.
Another paramount issue is the technology improvement required to raise the efficiency and working life of solar panels. Commercial PV module average efficiency in 2010 was close to 15%, but by 2021 it had reached over 20%, according to NREL. But efficiencies over 25% must be attained to place solar energy on an even playing field with fossil fuels. Research and development funding is needed to overcome these technological limitations and optimize the full performance of PV systems.
Another challenge confronted by regulation and market dynamics is that inconsistent policies and tariffs across regions may halt investment and hinder market growth, according to a press release by SEIA. For these reasons, all parties need to lobby for unified policies and incentives for the adoption of solar technologies. By creating an enabling environment for cooperation and partnership among governments, manufacturers, and consumers, the PV sector will be in a position to address these challenges and ultimately realize its global market growth potential.
