Solar PV Analysis of Yerevan, Armenia
Yerevan, Armenia (latitude 40.1817, longitude 44.5099) is a suitable location for generating solar power throughout the year due to its favorable seasonal energy production rates. On average, each kilowatt of installed solar capacity can generate 7.30 kWh per day in summer, 3.95 kWh per day in autumn, 2.71 kWh per day in winter, and 5.58 kWh per day in spring.
The higher energy production during the summer months can be attributed to longer daylight hours and increased temperatures that enhance the efficiency of solar panels in converting sunlight into electricity. Yerevan's climate is relatively mild as it lies within the Northern Temperate Zone; thus, extreme weather events that could impede solar production are less frequent compared to other regions of Armenia or neighboring countries.
With an average temperature range between -2°C and 28°C and annual rainfall of approximately 500mm, Yerevan offers ample sunshine for most months with minimal disruptions from adverse weather conditions such as heavy rain or snowfall that could significantly reduce solar output levels.
To optimize energy generation at this location, it is recommended to tilt solar panels at an angle of 34 degrees facing southward. This orientation ensures maximum exposure to sunlight throughout the year in Yerevan.
In conclusion, Yerevan's geographical position and climatic conditions make it a viable location for harnessing solar power all year round with proper installation techniques and panel orientation adjustments tailored to local environmental factors.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
Solar output per kW of installed solar PV by season in Yerevan
Seasonal solar PV output for Latitude: 40.1817, Longitude: 44.5099 (Yerevan, Armenia), 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 34° South in Yerevan, Armenia
To maximize your solar PV system's energy output in Yerevan, Armenia (Lat/Long 40.1817, 44.5099) throughout the year, you should tilt your panels at an angle of 34° 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 Yerevan, Armenia
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 Yerevan, Armenia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 24° South in Summer | 44° South in Autumn | 55° South in Winter | 32° 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 Yerevan, Armenia
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 Yerevan, Armenia.
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 Yerevan, Armenia
The topography around Yerevan, Armenia is generally flat and low-lying with some rolling hills. The nearby areas that would be most suitable for large-scale solar PV installations are the flat plains and open spaces in the surrounding countryside. There are also several mountain ranges to the north, east, and south of Yerevan which could provide good locations for solar PV farms due to their high elevation and clear skies. Additionally, there are many abandoned industrial sites near the city that could provide ideal locations for large-scale solar projects.
Armenia solar PV Stats as a country
Armenia ranks 75th in the world for cumulative solar PV capacity, with 183 total MW's of solar PV installed. Each year Armenia is generating 62 Watts from solar PV per capita (Armenia ranks 48th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Armenia?
Yes, there are incentives for businesses wanting to install solar energy in Armenia. The Armenian government has implemented a number of policies and programs to encourage the adoption of renewable energy sources, including solar energy. These include tax exemptions on imported equipment used for renewable energy projects, grants and loans from international organizations such as the World Bank and European Bank for Reconstruction and Development (EBRD), as well as subsidies from the Ministry of Energy Infrastructures and Natural Resources. Additionally, businesses can benefit from net metering schemes that allow them to sell excess electricity generated by their solar systems back into the grid at a premium rate.
