Can rooftop PV installations support the energy transition in the Baltic states?

Considering the above, the Baltic States have significant technical potential for rooftop PV installations to support the energy transition. EU policymakers have highlighted renewable energy communities as a key driver of this transition, as they promote citizen participation and local control over renewable energy decisions .

How much LCOE does a rooftop PV system cost?

Economic assessment of rooftop PV systems in Baltic States' multi-apartment buildings using Monte Carlo simulations. Projected LCOE for PV systems by 2050 ranges from 0.08 to 0.09 EUR/kWh at a 6 % discount rate, highlighting CAPEX sensitivity.

Can rooftop photovoltaic systems be used in multi-apartment buildings?

The study evaluates the LCOE for rooftop photovoltaic (PV) systems in multi-apartment buildings in the Baltic States, focusing on cost projections up to 2050. Using Monte Carlo simulations and stochastic modeling, the research incorporates key economic parameters such as CAPEX, OPEX, and discount rates to assess future LCOE trends.

What is the estimated rooftop PV energy production potential for 2022 – 2060?

In research geospatial methods and a high-resolution Building Integrated Solar Energy (BISE) supply model were used to estimate the rooftop PV energy production potential for the time period 2022–2060. Using the results of BISE , the estimated rooftop PV potential for EE is 6 TWh, LT 27 TWh, and LV 12,9 TWh.

Are rooftop PV systems economically viable?

The results show that rooftop PV systems are economically viable, with median LCOE values of 0.08 EUR/kWh for Latvia and Lithuania and 0.09 EUR/kWh for Estonia at a 6 % discount rate. Capital expenditures (CAPEX) are the most critical factor, with projected significant cost reductions by 2050 further enhancing viability.

Is LCOE more sensitive to capital costs of PV systems?

A previous study showed that LCOE is most sensitive to the capital costs of PV systems . A similar trend is observed for multi-apartment buildings rooftop PV systems in the Baltic States in the sensitivity analysis presented in Fig. 5, which shows the correlation between sensitive parameters and LCOE.
