The Solar Project Development Process: A Comprehensive Guide1. Site Selection and Feasibility Studies The first and arguably most critical step in any solar project is identifying a suitable site. Permitting and Regulatory Approvals.
There you have it, a guide to the solar project development process. While the development process can be complex, involving various assessments, design and engineering, permitting and financing, construction, and ongoing maintenance, the benefits of these projects are numerous.

Briefly, two other potential ways to store energy on a large scale are flywheels and a smart grid. The concept behind flywheels is fairly simple in that it is just the conversion of electrical energy to rotational kinetic energy for storage and then conversion back to electrical energy using a generator for extraction.
When these sources inevitably become more prevalent in the future, the combination of production unpredictability and lack of mass storage will result in energy waste, offsetting any potential benefits gained. Therefore it is of the utmost importance to research and develop effective means for large scale energy storage.
