There are plenty solar panels installed in the recent years. Their operation expectancy as far as I know is about 50 yrs. This will produce waste for our grandchildren. Please, reassure me, that these panels can be recycled somehow.

Yes, solar panels can be recycled -- in Europe this is required by law, and technology exists and is quickly being improved to facilitate this.

Legal requirements

In Europe, recycling of solar panels is required by law. Perhaps you've seen this symbol on some of your electronics:

The WEEE symbol

This is the symbol for the Waste Electrical and Electronic Equipment Directive. From Wikipedia:

The WEEE Directive is the European Community Directive 2012/19/EU on waste electrical and electronic equipment (WEEE) which, together with the RoHS Directive 2002/95/EC, became European Law in February 2003. The WEEE Directive set collection, recycling and recovery targets for all types of electrical goods.

This symbol now appears on all solar panels in EU countries. From an International Energy Agency - Photovoltaic Power Systems Programme (IEA-PVPS) report on PV recycling technologies:

[The WEEE] addresses the waste management of all electronics, including waste PV modules, in the EU member states. It requires 75%/65% (recovery/recycling rate) of waste PV modules by mass to be recycled through 2016, then increases to 80%/75% through 2018 and to 85%/80% thereafter.

From 2019 onwards, the EU will require 80% of solar panels to be recycled at the end of life, with greater than 85% recovery of usable materials.

PV recycling technology trends

The IEA-PVPS performs periodic technical reviews of PV recycling technologies and trends. This work is a collaborative effort of government organizations, non-profit organizations, and academic researchers from the U.S., the Netherlands, China, Japan, Korea, Belgium, and the European Union.

The report quoted above, titled "End‐of‐Life Management of Photovoltaic Panels: Trends in PV Module Recycling Technologies", goes on to say:

In addition to such a regulatory scheme [as the WEEE], it is obvious that recycling technologies must be available to meet the increasing requirements of WEEE. Available recycling facilities that treat PV modules can meet current WEEE requirements; additional research and development (R&D) is required to meet subsequent WEEE requirements at reasonable cost.

A review of patents and R&D spending on PV recycling technologies is then performed. The authors identify 178 different patents related to PV recycling technologies since 1976, with the rate increasing dramatically since 2009.
