Solar Energy Potential in Pisco, Ica, Peru

Pisco, Ica, Peru, located at latitude -13.7106 and longitude -76.208, offers generally favorable conditions for solar photovoltaic (PV) energy generation throughout the year. Situated in the tropics, this coastal location benefits from relatively consistent sunlight patterns compared to regions at higher latitudes. The seasonal solar energy production shows significant variation throughout the year. Summer months are the most productive, yielding approximately 7.36 kWh per day for each kilowatt of installed solar capacity. Spring follows closely with 6.52 kWh/day, while autumn produces a respectable 6.16 kWh/day. Winter represents the least productive season, with output dropping to 3.81 kWh/day per kilowatt installed. This seasonal pattern indicates that December through February (summer in the Southern Hemisphere) represents the peak production period for solar installations in Pisco. The substantial drop during winter months (June through August) suggests that supplementary power sources might be beneficial during this period for systems requiring consistent year-round output. For fixed panel installations in Pisco, Ica, the ideal tilt angle to maximize total year-round production is 11 degrees facing North. This specific angle optimizes the capture of solar radiation throughout the year, accounting for the Earth's elliptical orbit and Pisco's particular latitude.

Environmental Considerations

Several environmental factors could potentially impact solar production in Pisco:

• Coastal fog and humidity: Pisco's location near the Pacific Ocean means it experiences periodic coastal fog (particularly in winter mornings), which can temporarily reduce solar efficiency.
• Sand and dust: The arid coastal environment can lead to dust and sand accumulation on panels, gradually decreasing their effectiveness if not properly maintained.
• Salt spray: Proximity to the ocean exposes equipment to salt-laden air, which can accelerate corrosion of mounting hardware and electrical components.

Preventative Measures

To mitigate these environmental challenges, several installation and maintenance practices are recommended: Regular cleaning schedules should be implemented to remove dust and salt deposits from panel surfaces. Self-cleaning systems or hydrophobic coatings can reduce maintenance requirements. For the installation itself, using corrosion-resistant materials (marine-grade stainless steel or aluminum) for all mounting hardware is essential in this coastal environment. Additionally, slightly increasing the tilt angle beyond the mathematically optimal 11 degrees can help with natural cleaning during rainfall events, though this comes with a minor efficiency trade-off. Installing weather monitoring equipment alongside solar arrays can help operators anticipate foggy conditions and plan accordingly for potential production dips. With these considerations addressed, Pisco remains an attractive location for solar energy development, with strong production potential especially during summer, spring, and autumn months.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Pisco

Seasonal solar PV output for Latitude: -13.7106, Longitude: -76.208 (Pisco, Peru), 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 11° North in Pisco, Peru

To maximize your solar PV system's energy output in Pisco, Peru (Lat/Long -13.7106, -76.208) throughout the year, you should tilt your panels at an angle of 11° North 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 Pisco, Peru

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 Pisco, Peru. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
2° South in Summer	19° North in Autumn	29° North in Winter	7° North 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 Pisco, Peru

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 Pisco, Peru.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Pisco, Peru

The topography around Pisco, Peru presents a fascinating geographical landscape characterized by diverse terrain features. Located on Peru's southern coast at approximately -13.7106° latitude and -76.208° longitude, Pisco sits in a region where the arid coastal desert meets the foothills of the Andes Mountains. The immediate coastal area around Pisco is predominantly flat, featuring expansive desert plains that stretch inland from the Pacific Ocean. These plains are part of the Peruvian coastal desert, one of the driest regions on Earth. The terrain consists primarily of sand and gravel deposits, with minimal vegetation due to the extremely arid conditions. This coastal strip varies in width from approximately 5 to 40 kilometers before the landscape begins to rise toward the east.

Coastal Features

The Pisco coastline includes the notable Paracas Peninsula, which juts into the Pacific Ocean south of the city. This peninsula features dramatic cliffs and eroded formations where the desert meets the sea. The Paracas National Reserve, while ecologically significant, showcases the stark beauty of this desert-ocean interface with its distinctive reddish-yellow soil and rock formations.

Inland Terrain

Moving eastward from Pisco, the landscape gradually transitions from flat coastal plains to increasingly undulating terrain. The elevation begins to rise as one approaches the Andean foothills, with gentle slopes eventually giving way to more pronounced hills and valleys. This transitional zone between coast and mountains features dry riverbeds (quebradas) that occasionally fill during rare rainfall events. Further east, approximately 50-80 kilometers from Pisco, the terrain becomes significantly more rugged as it enters the western slopes of the Andes Mountains. These areas show dramatic increases in elevation, with steep slopes and narrow valleys creating a complex topographical profile.

Solar PV Suitability

For large-scale solar photovoltaic development, the inland desert plains east of Pisco offer particularly favorable conditions. The most suitable areas would be the flat to gently sloping terrain found approximately 10-30 kilometers inland from the coast. These locations benefit from several advantageous characteristics: The extensive desert plains provide large, continuous tracts of land with minimal competing land uses. These areas feature relatively flat topography, which significantly reduces construction costs and simplifies installation of solar arrays. The elevation is sufficient to avoid coastal fog that sometimes affects immediate shoreline areas, while still maintaining accessibility for infrastructure development. The transitional zones between the coastal plains and the beginning of the Andean foothills also present good opportunities, particularly on south-facing gentle slopes that receive consistent solar exposure throughout the year. These areas have minimal vegetative cover to clear and stable ground conditions for mounting systems. Areas to avoid would include the immediate coastline, where salt spray and occasional coastal fog could impact equipment longevity, and the steeper mountain slopes to the east, where installation would be technically challenging and costly. The dry riverbeds that cut through the region should also be avoided due to flash flood risk during occasional heavy rainfall events. The combination of stable ground conditions, minimal cloud cover throughout the year, and large expanses of undeveloped land make the inland desert plains east of Pisco among the most promising locations in Peru for utility-scale solar development.
