Solar panels typically have an efficiency range of 15% to 22%, with advancements in technology potentially increasing this efficiency through innovations such as bifacial panels and improved photovoltaic materials. Enhancements in solar cell design, such as tandem cells, and better energy storage solutions are also key areas for improvement. While solar energy offers significant benefits, including reduced greenhouse gas emissions and decreased reliance on fossil fuels, it also poses ecological concerns. These include land use for solar farms, potential habitat disruption, and the environmental impact of manufacturing and disposing of solar panels. Overall, the discussion emphasizes the need for ongoing research to balance the benefits of solar energy with its ecological footprint.
