My parents bought me all types of science kits and toys as a child, and now I am an environmental scientist studying renewable energy and resource management. Although photovoltaic panels can affix to existing structures, utility-scale systems require up to 10 acres per megawatt generated. Renewable energy can cut down on waste. Cost issues impact many homeowners who want to use solar power. We can reduce the effects of this disadvantage by placing solar panel farms in low-quality land areas or along existing transmission corridors, but it wont disappear entirely. Concentrated facilities can require up to 16.5 acres per megawatt. Readings from these and similar devices arent always as precise or as detailed as those from more intensive recorders, but for more casual purposes they can work just as well at a fraction of the cost.
