Photovoltaic (PV) systems are currently the most common method for producing solar electricity. Their great advantage lies in their many installation options and their variety of energy outputs, beginning with less than one kilowatt peak (kWp) systems, which can be installed on a single pole or small roof, up to systems of many Megawatts peak (MWp), covering extensive areas, which are suitable for power stations. The alternative solar thermal system is cheaper in terms of investment per installed kW and is more effective in terms of efficiency, space utilization and backup possibilities. However, the size required is at least of some dozens of MW and it is therefore suitable only for power stations.
Among the issues discussed in the forum were: quota assignment with preferable tariff, regulation, enhancement of local production, land use for commercial systems, and others.
