Solar PV Analysis of Debrecen, Hungary
Debrecen, Hungary, located at a latitude of 47.5232 and longitude of 21.6334, is a suitable location for solar PV generation, particularly during the sunnier seasons of summer and spring. In the summer months, an average of 6.76 kWh per day per kW of installed solar can be generated while in spring, this value is around 4.93 kWh per day per kW.
However, due to Debrecen's position within the Northern Temperate Zone, sunlight availability decreases significantly during autumn and winter months with average daily energy production dropping to 3.10 kWh/day per kW and 1.39 kWh/day per kW respectively.
Environmental factors such as heavy rain or snowfall can further reduce available sunlight at this location which may impact power generation from solar panels throughout the year but especially in colder seasons like winter when snow accumulation on panels could be an issue. To mitigate these challenges and ensure greater energy production overall, it is recommended that solar panels are installed at a fixed tilt angle of approximately 40 degrees south-facing to maximize exposure to sunlight.
Additionally, regular maintenance should be carried out on the installation site to keep panels clear from debris or snow buildup that could obstruct light absorption by the solar cells thereby ensuring higher efficiency in energy production regardless of seasonal variations or weather conditions experienced in Debrecen.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 59 locations across Hungary. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Debrecen
Seasonal solar PV output for Latitude: 47.5232, Longitude: 21.6334 (Debrecen, Hungary), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
Ideally tilt fixed solar panels 40° South in Debrecen, Hungary
To maximize your solar PV system's energy output in Debrecen, Hungary (Lat/Long 47.5232, 21.6334) throughout the year, you should tilt your panels at an angle of 40° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Debrecen, Hungary
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Debrecen, Hungary. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 31° South in Summer | 51° South in Autumn | 61° South in Winter | 40° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Debrecen, Hungary
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Debrecen, Hungary.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Debrecen, Hungary
The topography around Debrecen, Hungary is mainly flat with some minor hills and valleys. Areas that would be most suitable for large-scale solar PV are the flat, open areas to the east of the city which have direct exposure to sunlight throughout much of the day. The nearby plains and fields would also be well suited for this purpose.
Hungary solar PV Stats as a country
Hungary ranks 30th in the world for cumulative solar PV capacity, with 2,131 total MW's of solar PV installed. Each year Hungary is generating 218 Watts from solar PV per capita (Hungary ranks 22nd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Hungary?
Yes, there are incentives for businesses wanting to install solar energy in Hungary. The Hungarian government offers a range of financial incentives and subsidies for businesses that install solar energy systems. These include grants, tax credits, and other forms of support. Additionally, the government has implemented a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar energy.
