Self-consumption of electricity produced from PV systems in apartment buildings - Comparison of the situation in Australia, Austria, Denmark, Germany, Greece, Italy, Spain, Switzerland and the USA

Since 2000 grid-connected solar photovoltaic systems have increased their world-wide cumulative capacity more than 300 times to reach 400 GW at the end of 2017. Another doubling is forecasted until 2020 and the further development is coupled with the question at what prices solar photovoltaic electricity can be provided and delivered to the customers. The installation of PV systems for self-consumption is already now an interesting option for many people but in general limited to those who have access to a rooftop they own or can use. A new development to enable residents of multi apartment buildings to commonly use electricity generated by a PV system is a relatively new development and is still facing a lot of administrative and regulatory challenges.
