We explore the potential for predicting indoor photovoltaic energy on a forecasting horizon of up to 24 hours. The objective is to enable energy management approaches that exploit harvesting opportunities more strategically. for which they require more accurate energy intake predictions. Our study is based on a data set covering over 3 years. https://safeersappliancers.shop/product-category/aeg-dvb4850b-chimney-cooker-hood-black/
