I agree with much of what you have written here umair-ali786. There have been many advancements re solar power over the past decades, more advancements will come. For me solar is a matter of clean and abundant energy, I will accept resulting waste as an unavoidable consequence until solar has been further refined. Natcore Technologies and others are working tirelessly to improve efficiencies and more responsible manufacturing methods. I am aware that traditional energy providers are resistant to advancing solar. I am also aware that we are entering a Grand Solar Minimum phase, this natural cycle will impede solar advances, we have our work cut out for certain. I think energy storage (battery tech) is key to solar acceptance and efficiency at this point in time. Thanks for your post. Best.
