Note: The number of users of this project has grown considerably. This is great. Unfortunately, the operation of solar prognosis (Solarprognose) is not free of charge. The free weather API will soon be exhausted. Currently, as the operator, I pay the costs for the operation of Solarprognose.de. If each user would donate only 5 € per year, this would cover the current operating costs (may increase if bigger webserver required, more weather api requests etc.).
