In its review of the challenges and opportunities associated with massive deployment of solar PV generation, the Grid integration working group of the ETIP PV identified forecasting and observability as critical technologies for the planning and operation of the power system with large PV penetration. In this white paper ETIP PV set out to spell out in more details what features are needed from these technologies and what is the state of the art.

It has been shown that the PV module price will most likely to be halved again and BoS price will decrease by more than 35% by 2030, leading to an overall PV system CAPEX reduction of about 45%. It must be noted that this development does not require any major technology breakthroughs but is a natural cause from continuing efforts in reducing materials use, impoving efficiency and developing manufacturing processes. At the same time, PV system OPEX is expected to decrease by 30%. PV LCOE will decrease by 30-50% from 2014 to 2030, depending on the volume growth and learning rate.

This report records the statements made by a number of experts from Europe’s PV manufacturing industry interviewed between September 2014 and June 2016. It covers most sections of the manufacturing chain in Europe.

For the development of a thriving BIPV-sector it will be crucial to see the PV-module as a building component technology than rather than a pure PV-module, delivering electricity. In order to exploit the huge economic potential of BIPV and its required close link with local building markets, it will be necessary to (re)organize the value chain, e.g. by enabling flexible ´production on demand´ by the BIPV element producer, in the amount, size, colour etc specified in a specific building project). This position paper outlines Strategies for integrated research, innovation and competitiveness within the Energy Union in the field of Energy Efficiency in buildings & cities and BIPV.

With this paper we set to clarify the terms of this discussion: how is penetration of PV into power grids evaluated? What are the current levels? Which barriers may prevent increasing these levels? Which concepts have been put forward to open these barriers? Which benefits can PV systems provide for existing and new grids?
