Solar PV Analysis of Baixa Da Banheira, Portugal
The location at Baixa da Banheira, Portugal is pretty good for generating energy via solar photovoltaic (PV) systems year-round. The amount of electricity that can be produced from each kilowatt (kW) of installed solar varies across the seasons.
In the summer, you can expect around 7.69 kilowatt-hours (kWh) per day for each kW of installed solar, which is quite high and makes it an ideal time for solar energy production. In spring, the output is also fairly high at 6.41 kWh/day per kW.
During autumn and winter, the output decreases to 4.52 kWh/day and 2.66 kWh/day per kW respectively due to shorter daylight hours and lower sun intensity; however, these figures are still reasonable considering that this location is in Northern Temperate Zone where winters can be quite cold and cloudy.
For a fixed panel installation at this location, the best angle to tilt your panels for maximum total year-round production from solar PV is towards south with an inclination of 33 degrees.
There could be certain factors such as local weather conditions or topography that might affect the performance of your solar installation in Baixa da Banheira.
Portugal has a Mediterranean climate which means there could be periods with heavy rains especially during winter months that may reduce sunlight exposure on panels affecting their efficiency temporarily.
Also if there are any tall buildings or trees nearby they could cast shadows on your panels reducing their exposure to sunlight especially during mornings or late afternoons when sun's position is low in sky; thus affecting electricity generation potential.
To overcome these challenges you should ensure proper site selection where no shading objects are present close by; also regular maintenance like cleaning panels after heavy rains can help maintain their efficiency levels intact over time.
In conclusion while there might be some challenges due to seasonal variations in sunlight intensity or local weather conditions overall Baixa da Banheira, Portugal is a good location for solar PV installations.
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 Baixa Da Banheira
Seasonal solar PV output for Latitude: 38.6533, Longitude: -9.0444 (Baixa Da Banheira, 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 Baixa Da Banheira, Portugal
To maximize your solar PV system's energy output in Baixa Da Banheira, Portugal (Lat/Long 38.6533, -9.0444) 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 Baixa Da Banheira, 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 Baixa Da Banheira, 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 |
|---|---|---|---|
| 22° 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 Baixa Da Banheira, 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 Baixa Da Banheira, 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 Baixa Da Banheira, Portugal
Baixa da Banheira is located in the Setúbal District of Portugal, which is part of the Lisbon metropolitan area. The topography around Baixa da Banheira is relatively flat and low-lying, with a mix of urban areas and agricultural land. The region features a Mediterranean climate with hot summers and mild winters, making it potentially suitable for solar energy production.
For large-scale solar photovoltaic (PV) installations, open spaces with high sun exposure are needed. Considering this:
1. Agricultural Land: There are various agricultural fields around Baixa da Banheira that could be considered for dual-use or agro-photovoltaics systems where farming and solar energy production coexist.
2. Industrial Zones: The industrial zones south of Baixa da Banheira near Moita might also be suitable locations due to their proximity to existing infrastructure.
3. Unused Land: Any unused or barren land in the vicinity that gets ample sunlight can also be used for setting up PV panels.
4. Rooftop Solar: In urban parts of Baixa de Banheira, rooftops can be utilized for installing small-scale PV systems.
However, actual suitability would depend on several factors including soil condition, land ownership status, local regulations regarding renewable energy projects as well as detailed solar irradiation data etc., hence thorough feasibility studies would need to be conducted before identifying specific sites.
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.
