The Sun, that great ball of gas at the heart of our solar system, keeps us warm and gives us light, provides photosynthesis to make plants grow, and provides gravity to keep us in orbit around it. Most importantly, it provides energy that we can convert to clean power. Developers wanting to create solar-associated applications need APIs to do the job, and ProgrammableWeb's Solar category is the place to find them. To receive updates about Solar APIs, click the TRACK THIS CATEGORY button below. And, if you want updates from other ProgrammableWeb categories, be sure to click the track button on those category pages as well.
