Solar PV Analysis of Montijo, Portugal
In Montijo, Setúbal, Portugal, located at latitude 38.7023 and longitude -8.9793, the potential for solar energy generation is significant due to its favorable climatic conditions. The average kilowatt-hours (kWh) produced per day for each kilowatt (kW) of installed solar capacity varies by season: it's highest in the summer at 8.19 kWh/day, followed by spring with 6.33 kWh/day, autumn with 4.54 kWh/day, and lowest in winter at 2.59 kWh/day.
The city's geographical location is conducive to harnessing solar power throughout the year due to a predominance of sunny days; however occasional cloud cover or rainfall may lead to slight reductions in energy production from photovoltaic panels.
For optimal solar energy capture using fixed panel installations in Montijo, Setúbal, tilting panels at an angle of approximately 33 degrees facing south is recommended as this aligns best with the sun’s path across the sky throughout the year.
While Montijo's climate and geographic position are generally advantageous for solar power generation, local factors such as shading from buildings or vegetation could potentially obstruct sunlight reaching the panels and therefore impact their performance negatively.
To mitigate against these potential obstructions and maximize energy production from installed panels, careful site assessment prior installation should be conducted to avoid shaded areas during peak sun hours whenever possible; alternatively consider trimming or removing any obstructive vegetation if feasible without causing environmental harm.
In conclusion, while there are some minor challenges that can affect optimum performance of solar PV systems in Montijo Portugal they can be effectively managed through appropriate siting and installation practices making this location highly suitable for generating substantial amounts of clean renewable energy year-round.
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 179 locations across Portugal. 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 Montijo
Seasonal solar PV output for Latitude: 38.7023, Longitude: -8.9793 (Montijo, Portugal), 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 33° South in Montijo, Portugal
To maximize your solar PV system's energy output in Montijo, Portugal (Lat/Long 38.7023, -8.9793) throughout the year, you should tilt your panels at an angle of 33° 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 Montijo, Portugal
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 Montijo, Portugal. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 23° South in Summer | 43° South in Autumn | 54° South in Winter | 31° 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 Montijo, Portugal
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 Montijo, Portugal.
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 Montijo, Portugal
The topography around Montijo, Portugal is generally flat. The area surrounding the city is mostly farmland and marshland, with some hills in the distance. Areas that would be most suited to large-scale solar PV installations are those that have an unobstructed view of the sun during all hours of daylight and clear skies. The flat terrain near Montijo makes it ideal for this type of installation as there are no obstructions blocking out the sun's rays. Additionally, areas that are close to transportation networks such as highways or railways could also be good locations for large-scale solar installations due to their proximity to potential customers or buyers.
Portugal solar PV Stats as a country
Portugal ranks 32nd in the world for cumulative solar PV capacity, with 1,801 total MW's of solar PV installed. This means that 3.40% of Portugal's total energy as a country comes from solar PV (that's 23rd in the world). Each year Portugal is generating 174 Watts from solar PV per capita (Portugal ranks 29th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Portugal?
Yes, there are several incentives for businesses wanting to install solar energy in Portugal. The Portuguese government offers a range of financial incentives and tax breaks for businesses that invest in renewable energy sources such as solar power. These include grants, loans, and tax credits. Additionally, the government has set up a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar power. This helps to make investing in solar energy more attractive to businesses.
