Solar PV Analysis of Helwan, Egypt
Helwan, Cairo Governorate, Egypt is a fairly good location for generating solar power throughout the year. The amount of electricity that can be produced from solar panels depends on the sunlight they receive, which varies with the seasons. In summer and spring, when there's more sunlight, you could expect to generate around 8.72 and 7.94 kilowatt-hours (kWh) per day respectively for each kilowatt (kW) of installed solar power. During autumn and winter, when days are shorter and there's less sunlight, this would drop to about 5.90 kWh/day in autumn and even lower to about 4.44 kWh/day in winter.
So if you were thinking about when might be the best times of year to generate solar power at this location - it would definitely be during the sunnier months of spring and summer.
If you're planning on installing fixed panel solar systems here, tilting your panels at an angle of 26 degrees towards south will help maximize your yearly energy production because it aligns them better with the path of the sun across the sky.
As for potential local factors that could hinder your solar production - Helwan is located in a desert environment which means dust storms may occur that can cover your panels with sand or dust reducing their efficiency significantly by blocking out sunlight. Also high temperatures can decrease efficiency as well since most photovoltaic cells perform better at cooler temperatures.
To prevent these issues affecting your energy production too much:
1) Install automatic or semi-automatic cleaning systems for regular removal of dust from panel surfaces.
2) Ensure adequate air circulation around panels so they don't overheat.
3) Consider using special PV modules designed specifically for operation under high-temperature conditions.
4) Regular maintenance checks should also be performed to keep everything running smoothly.
In summary then – yes Helwan has some challenges due its desert climate but overall it’s still a very viable place for harnessing solar energy especially in the sunnier months of spring and summer.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 80 locations across Egypt. 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 Helwan
Seasonal solar PV output for Latitude: 29.8415, Longitude: 31.2953 (Helwan, Egypt), 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 26° South in Helwan, Egypt
To maximize your solar PV system's energy output in Helwan, Egypt (Lat/Long 29.8415, 31.2953) throughout the year, you should tilt your panels at an angle of 26° 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 Helwan, Egypt
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 Helwan, Egypt. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 14° South in Summer | 35° South in Autumn | 45° South in Winter | 23° 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 Helwan, Egypt
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 Helwan, Egypt.
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 Helwan, Egypt
Helwan, Egypt is located in the northern part of the country, just south of Cairo. The topography around Helwan is generally flat with some hills and plateaus. The region is primarily desert with minimal vegetation due to its arid climate.
Given this environment, there are several areas nearby that would be suitable for large-scale solar PV installations. These include:
1. Desert Areas: With vast expanses of flat terrain receiving high amounts of sunlight year-round, the surrounding desert regions would be ideal for large-scale solar farms.
2. Rooftops in Urban Areas: While not as expansive as desert areas, rooftops in urban areas like Helwan itself or nearby Cairo could also support smaller scale solar PV installations.
3. Unused Land Near Industrial Zones: There are various industrial zones near Helwan where unused land can be utilized for setting up solar power plants without causing much disturbance to existing infrastructure or population.
4. Along Highways: Installing solar panels along highways can also be a good option as it utilizes otherwise unused land and has easy access to grid connections.
However, these suggestions should always be evaluated against local regulations and potential environmental impacts before proceeding with any installation project.
Egypt solar PV Stats as a country
Egypt ranks 34th in the world for cumulative solar PV capacity, with 1,675 total MW's of solar PV installed. Each year Egypt is generating 17 Watts from solar PV per capita (Egypt ranks 67th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Egypt?
Yes, there are incentives for businesses wanting to install solar energy in Egypt. The Egyptian government has implemented a number of policies and programs to encourage the adoption of renewable energy sources such as solar power. These include feed-in tariffs, net metering, tax exemptions, and subsidies. Additionally, the government has established a Renewable Energy Authority (REA) to oversee the development of renewable energy projects in Egypt.
