Solar PV Analysis of Taiz, Yemen
Taiz, Ta‘izz, Yemen is a pretty good spot for generating solar energy all year round. This is because it's located in the tropics where sunlight is more or less consistent throughout the year. The amount of electricity you can expect to generate from each kilowatt of installed solar panels varies slightly depending on the season: 6.72kWh/day in summer, 6.67kWh/day in autumn, 6.40kWh/day in winter and 7.68kWh/day in spring.
Spring seems to be the best time for generating solar energy at this location because that's when your panels will produce their maximum output (7.68 kWh per day). However, even during winter which has the lowest output (6.40 kWh per day), you're still getting a decent amount of electricity.
If you're installing fixed panel installations, tilting them at an angle of 13 degrees towards South will give you maximum production over the course of a year.
As far as environmental or weather factors that could affect your solar production are concerned, there might be some issues but only if they're significant enough to block sunlight reaching your panels - things like dust storms or heavy cloud cover during rainy seasons could potentially reduce how much power your panels generate.
To deal with these potential problems and ensure greater energy production from your solar installation:
1) Regularly clean dust off your panels so they can absorb as much sunlight as possible.
2) Install them somewhere high up and clear from any obstructions like buildings or trees that could cast shadows on them.
3) Consider investing in systems designed to maximize exposure to sunlight even under cloudy conditions.
Remember though - while these measures can help improve performance somewhat, they won't completely offset major disruptions like prolonged periods without sunshine due to heavy rainfall or dust storms; such events would naturally lead to lower power generation from any kind of solar setup regardless of where it's located.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 10 locations across Yemen. 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 Taiz
Seasonal solar PV output for Latitude: 13.5742, Longitude: 44.0037 (Taiz, Yemen), 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 13° South in Taiz, Yemen
To maximize your solar PV system's energy output in Taiz, Yemen (Lat/Long 13.5742, 44.0037) throughout the year, you should tilt your panels at an angle of 13° 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 Taiz, Yemen
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 Taiz, Yemen. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 2° North in Summer | 20° South in Autumn | 29° South in Winter | 7° 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 Taiz, Yemen
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 Taiz, Yemen.
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 Taiz, Yemen
Taiz, Yemen is located in the southwestern part of the country and it is surrounded by mountains. The region has a rugged topography with highlands, valleys, and steep slopes. The city itself sits at an elevation of around 1,400 meters above sea level.
In terms of solar PV potential, areas with flat or gently sloping terrain would be more suitable for large-scale solar installations due to ease of installation and maintenance. Given Taiz's mountainous terrain, flatter regions might be harder to find nearby. However, southward towards the coastal plain along the Red Sea or eastward towards less mountainous regions may provide better prospects.
Additionally, rooftop solar installations could also be considered within Taiz itself given its urban nature.
It's important to note that while physical geography plays a role in determining suitable locations for solar PV projects; factors like sunlight intensity and duration (solar irradiance), local weather patterns (cloud cover), land use restrictions and proximity to transmission lines are also critical considerations when assessing suitability for large-scale solar PV projects.
Yemen solar PV Stats as a country
Yemen ranks 67th in the world for cumulative solar PV capacity, with 253 total MW's of solar PV installed. Each year Yemen is generating 8 Watts from solar PV per capita (Yemen ranks 75th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Yemen?
Unfortunately, there are currently no incentives for businesses wanting to install solar energy in Yemen. The country is facing a severe economic crisis and the government does not have the resources to provide any financial support for renewable energy projects. However, some international organizations such as the World Bank and UNDP have been providing technical assistance to help develop renewable energy projects in Yemen.
