How much is solar to dollar?

I'm curious, could you please explain in detail how the conversion rate from solar energy to dollars is calculated? Specifically, what factors influence this exchange rate and how do they contribute to the overall value? Is there a standard methodology used in the industry to determine this ratio, or does it vary depending on the specific project or application? Furthermore, how does this compare to other forms of energy in terms of cost-effectiveness and environmental impact? I'm looking for a comprehensive understanding of the economics behind solar energy and its role in the global energy market.
