6 FAQs about Power generation of photovoltaic panels facing west in Southern Europe

Which direction should solar panels be installed in Ukraine?

Although the installation of solar modules facing south is the most common in Ukraine and is efficient in terms of annual energy production, sometimes the east-west orientation can be more promising under certain conditions. Let's take a closer look at this case study. The actual view of the panels with the orientation to the east and to the west

Are east-west facing vertical PV panels a good investment?

The study shows that with higher PV penetration, aligning more closely with key EU policy initiatives (EU Solar Energy Strategy, Green Deal, REPowerEU Plan), east-west faced vertical PV panels can play a favourable role to achieve a more balanced and more integrated power system in the EU by 2040.

What is the best orientation for solar panels in the UK?

The best orientation for solar panels in the UK in terms of annual energy generation for a PV system is due south. However, there are more things to consider than purely the total generation, and the daily load profile should be taken into consideration when trying to maximise the benefits of a solar PV system.

Should solar panels be split across East and west facing roofs?

Therefore, if you were to install a solar PV array split across both east and west facing roofs, the system would start generating electricity earlier in the day and stop generating electricity later in the day. This gives the advantage of having a wider power production window compared to a system orientated due south.

Could bifacial photovoltaic systems help fix energy prices?

Large-scale deployment of innovative bifacial photovoltaic (PV) systems, oriented east and west instead of the conventional south-facing setup, could significantly help fix energy price swings, cut fossil fuel use, and strengthen Europe's clean energy path, new research finds.

Could east-west facing bifacial solar panels boost electricity prices?

East-west facing bifacial solar panels could boost solar power's economic value and help stabilise electricity prices across the EU.
