The internal rate of return (IRR) has emerged as the gold standard for evaluating solar power generation profitability. Calculate ROI Here The average American household pays a monthly electric bill of $118. When you go solar, the power generated by your solar panels replaces the electricity you buy from the utility company, reducing or completely eliminating. . What is Solar IRR? IRR is a financial metric to evaluate an investment's profitability over a specific timeframe. In simpler terms, it tells the annualized percentage return that an investment would need to generate to break even on all the costs and cash flows associated with the project. With this article, we aim to help you understand these terms, their implications, and attempt to make this journey smoother for you as a consumer. When you invest in a solar system, you receive non-taxable dividends each year in the form of the cash that is no longer being paid to the utility company.
