With an increased demand for solar, the manufacturing cost has declined across the globe. Generous solar subsidies in developed countries combined with heavy production subsidies in developing countries have spurred the manufacturing process. This has resulted in a demand and supply imbalance which has slowed the price down. Over the long term, this is expected to balance out and costs will gradually decline. Read the full article to learn more about the costs associated with solar power systems and why they're becoming more affordable.
