Economic evaluation of the Power grid tariff for households With solar Power installed

Abstract

This paper focuses on alternative grid tariffs for household customers with roof top PV-panels ("prosumers"), and evaluates how alternative grid tariffs might affect the benefit from investing in a roof top PV-panel. The paper further shows how different orientations of the PV-panels can affect the benefits for the prosumers subjected to different grid tariffs (for example a power grid tariff), where the idea is that self-consumption will produce the best economic yield. First different alternatives for distribution grid tariffs to household customers and prosumers are presented. Afterwards, the paper presents empirical data showing typical consumption and generation for some households with PV-panels (located in south-eastern and central Norway).
