Are distributed solar photovoltaic systems the future of energy?

Distributed solar photovoltaic (PV) systems are projected to be a key contributor to future energy landscape, but are often poorly represented in energy models due to their distributed nature. They have higher costs compared to utility PV, but offer additional advantages, e.g., in terms of social acceptance.

Is distributed PV a cost-optimal energy system?

We show that including distributed PV in a cost-optimal European energy system leads to a cost reduction of 1.4% for the power system, and 1.9–3.7% when the complete sector-coupled system is analyzed. This is because, although distributed PV has higher costs, the local production of power reduces the need for HV to LV power transfer.
