Solar energy is often celebrated as a clean and limitless power source, but it comes with challenges that can’t be ignored. From high installation costs and land-use conflicts to intermittency, degradation, and the looming wave of solar waste, the disadvantages of solar energy highlight the need for smarter solutions. Issues like toxic materials, supply chain pressures, and geographic limitations add further complexity. Addressing these challenges through innovation, recycling, and policy will ensure solar remains a sustainable force in the global energy transition.
