Under typical UK conditions, 1m 2 of PV panel will produce around 100kWh electricity per year, so it would take around 2.5 years to "pay back" the energy cost of the panel. PV panels have an expected life of least 25 to 30 years, so even under UK conditions a PV panel will generate many times more energy than was needed to manufacture it.

Using reflectors to increase the yield of solar panels

If more light is fed to the panels through a reflector, the temperature variations of the panels themselves will be greater, and the energy output is less predictable.
