When or where is solar energy worth exploiting?

Solar energy is worth exploiting in regions with high levels of sunlight and clear skies, such as deserts or areas closer to the equator. It is particularly beneficial in remote locations where extending traditional power grids is costly. Additionally, investing in solar energy can be economically viable when local electricity prices are high or when there are incentives and subsidies for renewable energy projects. Solar energy systems are also advantageous in urban settings for rooftop installations, contributing to energy independence and sustainability.
