Solar PV Analysis of Hvar, Croatia
Hvar, Split Dalmatia, Croatia, situated at a latitude of 43.1729478 and longitude of 16.4411136 within the Northern Temperate Zone, is a favorable location for solar power generation throughout the year. During the summer season, an average of 7.59 kWh per day per kW of installed solar can be expected due to longer daylight hours and higher sun intensity. In autumn and winter, energy production remains relatively consistent with averages of 3.61 kWh/day and 2.02 kWh/day per kW of installed solar respectively, despite shorter daylight hours and lower sun intensity during these seasons. The spring season also offers promising results with an average generation of 5.80 kWh/day per kW of installed solar as sunlight hours and intensity increase compared to cooler months.
For optimal energy production in Hvar, Split Dalmatia, fixed panel installations should be tilted at an angle of 36 degrees facing south to maximize exposure to sunlight throughout the year.
It is important to note that local weather conditions such as heavy rain or cloud cover could impact solar energy production by reducing available sunlight hours or intensity when compared to clear days without clouds or rain present in Hvar, Split Dalmatia, Croatia's Northern Temperate Zone location . To mitigate potential losses in energy production due to these factors, it is recommended that proper maintenance practices are followed for cleaning panels regularly and ensuring they remain free from obstructions such as debris or vegetation growth that may block sunlight access on cloudy days or after rainfall events
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 29 locations across Croatia. 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 Hvar
Seasonal solar PV output for Latitude: 43.1729478, Longitude: 16.4411136 (Hvar, Croatia), 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 36° South in Hvar, Croatia
To maximize your solar PV system's energy output in Hvar, Croatia (Lat/Long 43.1729478, 16.4411136) throughout the year, you should tilt your panels at an angle of 36° 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 Hvar, Croatia
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 Hvar, Croatia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 27° South in Summer | 46° South in Autumn | 57° South in Winter | 35° 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 Hvar, Croatia
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 Hvar, Croatia.
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 Hvar, Croatia
Hvar is located in the Adriatic Sea off the Dalmatian coast of Croatia. The topography around Hvar is mostly hilly and mountainous, with some areas of flat plains. The highest point in the area is Sveti Nikola, which has an elevation of 628 meters (2,060 feet).
The most suitable areas for large-scale solar PV near Hvar are the flat plains close to the coast. These areas have ample sunlight and relatively low levels of cloud cover, making them ideal locations for solar energy production. Additionally, these areas have access to roads and transmission lines that can be used to transport electricity generated from solar power plants to consumers.
Croatia solar PV Stats as a country
Croatia ranks 84th in the world for cumulative solar PV capacity, with 109 total MW's of solar PV installed. Each year Croatia is generating 27 Watts from solar PV per capita (Croatia ranks 60th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Croatia?
Yes, there are incentives for businesses wanting to install solar energy in Croatia. The Croatian government offers a number 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 set up a feed-in tariff system which guarantees a certain price per kilowatt hour (kWh) generated from renewable sources such as solar energy. This helps to make investing in solar energy more attractive for businesses.
