before it is widely used, of course the new invention must be more profitable and less negative effects. indeed, solar panels can be an alternative source of energy, and of course this is a technological development that is more environmentally friendly. and I think that with continued research, other energy resources will emerge which will be more effective and efficient in the future
There's no need to fully develop another iteration of solar panels, what it needs to do is to make it more commercial because it's still expensive as it was first released to the public, and we don't need to just focus on these things, we need storage for energy because most energy that is harvested is either wasted or dissipates over time because there's no proper storage for it.
Renewable energy cannot be stored because it is contineous replinishment process, and i believe this will be the future resources of energy since now mostly the world rely on using fossil fuels and time come we all realize what damage have been brought to our beautiful planet before it all exhausted.
