False!
This could not be further from the truth. The average cost for solar energy has fallen dramatically
over the last 10 years – by around 85%.
It is now cheaper to generate power from the sun than from coal. The payback period for the PV
system in a detached house is normally around ten years.
False!
We all love a sunny day, but the sky does not need to be cloud free for your solar modules to
generate power. If it is very hot, the efficiency of the modules actually declines. Solar collectors work
both on sunny and on cold and cloudy days.
False!
It takes two years for a photovoltaic system to generate the same amount of energy it took to produce
it. Over its entire service life it will produce many times this amount.
False!
Completely the opposite – a PV system actually increases the value of a property. Energy efficiency is
increasingly becoming an attractive feature for potential home buyers.
False!
Solar modules are designed to last more than 25 years. After that, they can be recycled. Studies have
shown that the energy consumption for the production of modules is covered by the generation of
PV energy after just four years. This means that the reduced CO2 emissions due to the use of solar
modules far outweigh the emissions that arise during the production of solar modules.
False!
Solar modules can even extend the service life of a roof as they protect the part of the roof that they
cover. The modules do not need any maintenance after installation and are also very durable (25+
years). Modules do not normally need to be cleaned either – the rain does this.
False!
As the efficiency of solar modules has significantly increased over the years, they have now reached
an extremely high level of efficiency. This efficiency will continue to improve thanks to technological
progress, but in smaller amounts than before. The potential increase in efficiency of future panels is
low compared to today’s ready-to-install panels.
True!
Compared to other sources of energy, solar energy is very environmentally friendly. Solar energy can
be used throughout the entire world and is available every day. For as long as the sun is around.
Which is the next 5 billion years.
