Globally, PV prosumers account for a significant share of the total
installed solar PV capacity, which is a growing trend with
ever-increasing retail electricity prices. Further propelled by
performance improvements of solar PV and innovations that allow for
greater consumer choice, with additional benefits such as cost
reductions and availability of incentives. PV prosumers may be one of
the most important enablers of the energy transition. PV prosumers are
set to gain the most by maximising self-consumption, while avoiding
large amounts of excess electricity being fed into the grid.
Additionally, electricity and heat storage technologies, heat pumps and
battery electric vehicles are complementary to achieve the highest
possible self-consumption shares for residential PV prosumer systems,
which can reach grid-parity within this decade in most regions of the
world. This research finds the cost optimal mix of the various
complementary technologies such as batteries, electric vehicles, heat
pumps and thermal heat storage for PV prosumers across the world by
exploring 4 different scenarios. Furthermore, the research presents the
threshold for economical maximum battery capacity per installed PV
capacity, along with self-consumption ratios, demand cover ratios and
heat cover ratios for 145 different regions across the world. This is a
first of its kind study to conduct a global analysis of PV prosumers
with a range of options to meet their complete energy demand from a
future perspective, up to 2050. Maximising self-consumption from solar
PV generation to meet all energy needs will be the most economical
option in the future, for households across most regions of the world.
