6 FAQs about [The effect of photovoltaic solar panels on Bulgarian roofs]

Are solar panels a viable option for self-consumption in Bulgaria?

Conversely, households and institutions interested in installing solar panels for self-consumption are still stuck with administrative hurdles In the statistics of the International Renewable Energy Agency (IRENA), Bulgaria had 1.28 GW at the end of 2021 and 1.95 GW just one year later. The measure is expressed in nominal or peak capacity.

Why are distributed solar PV projects being built in Bulgaria?

Most distributed solar PV projects currently being built in Bulgaria are being configured purely for self-consumption; in other words, they are not connected to the grid, and are being used strictly to reduce the customer’s electricity bill. This makes it harder for distribution system operators (DSOs) to monitor, and control.

What is the biggest solar PV plant to be built in Bulgaria?

This is also one of the biggest solar PV plants to be constructed in Bulgaria in recent years. With the solar PV plant, Aurubis Bulgaria will save some 11.700 MWh per year from grid electricity consumption (sufficient for approx. 12.000 households), which will cover an average of 2.5% of the electricity needs of its smelter facility.

Does photovoltaic green roof affect energy balance?

Energy fluxes on photovoltaic green roof are investigated and modelled in detail. Longwave radiation of photovoltaics significantly impacts energy balance. Shading and view factor calculation in 3D is developed and shared. Parametric model for photovoltaic green roof surface temperature is developed.

Are photovoltaic roofs sustainable?

Expanding on the benefits of this integration, the photovoltaic green roof systems have a significant potential for sustainable urban development and even climate change mitigation with carbon emissions reduction (Chen et al., 2024).

Are rooftop surfaces suitable for solar photovoltaic (PV) placement?

Similarly, the rooftop surfaces are also suitable for solar photovoltaic (PV) placement (Thebault et al., 2020), the total capacity of which in the world has strongly increased in the last decades (Gernaat et al., 2020) and has also had various incentive policies implemented in different countries (Kılıç & Kekezoğlu, 2022).
