Solar PV Analysis of Chisinau, Moldova
In Chisinau, Chișinău Municipality, Moldova, located at a latitude of 47.0042 and longitude of 28.8574, the generation of solar power varies significantly with the changing seasons due to its position in the Northern Temperate Zone. During summer months, there is an average production rate of 6.44 kWh per day for each kW installed solar capacity due to longer daylight hours and more direct sunlight exposure. However, in winter months when daylight hours are shorter and sunlight is less direct, this rate drops drastically to an average production rate of just 1.33 kWh per day.
During autumn and spring seasons where daylight hours are intermediate between summer and winter extremes, solar energy production rates stand at an average of 3.07 kWh/day in Autumn and slightly higher at an average of 4.63 kWh/day during Spring.
For fixed panel installations in Chisinau, Chișinău Municipality, it has been determined that panels should ideally be tilted towards the south at an angle of approximately 40 degrees for optimal year-round energy production.
However, local weather conditions could potentially impede solar power generation as Chisinau experiences frequent cloudy days which can limit sunlight exposure on panels as well as heavy precipitation that can obstruct or reduce light penetration through cloud cover.
To mitigate these potential challenges when installing solar systems in this location; ensuring proper panel positioning (to maximize exposure during peak sun hours), considering weather-resistant materials for durability against heavy precipitation events; regular cleaning/maintenance routines to remove any debris or accumulation that may block sunlight are recommended measures that could help ensure greater energy output from installed systems despite these environmental factors.
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 9 locations across Moldova. 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 Chisinau
Seasonal solar PV output for Latitude: 47.0042, Longitude: 28.8574 (Chisinau, Moldova), 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 Chisinau, Moldova
To maximize your solar PV system's energy output in Chisinau, Moldova (Lat/Long 47.0042, 28.8574) 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 Chisinau, Moldova
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 Chisinau, Moldova. 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 | 50° South in Autumn | 60° South in Winter | 39° 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 Chisinau, Moldova
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 Chisinau, Moldova.
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 Chisinau, Moldova
The topography around Chisinau, Moldova is mostly flat with some rolling hills, and the nearby areas that would be most suitable for large-scale solar PV installations are those that receive direct sunlight throughout the day. The city of Chisinau itself is located in a valley between two hills, so any area outside of this valley should have ample access to direct sunlight. Additionally, there are several open fields and grasslands surrounding Chisinau which could provide ideal locations for large-scale solar PV systems.
