Your logic only works if manufacturing of solar panels is an energy intensive tasks, which it isn't. The total energy expenditure of manufacturing, shipping and installing solar panels is recouped after operating the solar panel for roughly a year.
Solar panels are now cheaper than coal because you need to dig up coal and bring it to the power plant, which costs more than the 4cents per kwh which LCOE solar now costs.
- alexey-salmin 2y agoIt is energy intensive. Studies I saw give 2 to 8 years to offset the PV alone, not counting inverters and the rest. One case of a heavy hail during that time and a panel becomes a net energy loss, a pure damage to the environment. > Solar panels are now cheaper than coal because you need to dig up coal and bring it to the power plant, which costs more than the 4cents per kwh which LCOE solar now costs. You're taking again the LCOE of solar produced from coal. Digging up coal and bringing it to the plant requires very little energy.
