Solar PV Analysis of Perafita, Portugal
In simpler terms, Perafita in Portugal has a decent potential for generating solar energy throughout the year. The amount of energy you can get from solar panels varies depending on the time of year: it's best in summer and spring when you can expect around 7.43 and 6.09 kilowatt-hours per day for each kilowatt of power your solar panels have installed. In autumn and winter, the energy production drops to around 3.97 and 2.19 kWh/day per kW respectively due to shorter daylight hours.
To get the most out of your solar panel system in Perafita all year round, it's recommended to tilt your panels at an angle facing 35 degrees towards the South.
However, there might be some local factors that could affect how well your solar panels work here. For example, if there are lots of buildings or trees blocking sunlight from reaching your panels, this could reduce their efficiency significantly.
Weather conditions like heavy rainfall or snowfall could also impact how much sunlight reaches your panels as well as potentially damaging them physically - so it's crucial to consider weatherproofing measures when installing them.
If these obstacles are significant enough, they may need to be addressed before installing a solar panel system - for instance by trimming overgrown trees or choosing a location with less shade if possible.
The key is ensuring maximum exposure to sunlight throughout the day and across different seasons – so careful planning will go a long way towards getting more energy production from your solar installation at this location.
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 Perafita
Seasonal solar PV output for Latitude: 41.2245, Longitude: -8.6964 (Perafita, 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 35° South in Perafita, Portugal
To maximize your solar PV system's energy output in Perafita, Portugal (Lat/Long 41.2245, -8.6964) throughout the year, you should tilt your panels at an angle of 35° 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 Perafita, 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 Perafita, Portugal. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° South in Summer | 46° South in Autumn | 56° South in Winter | 34° 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 Perafita, 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 Perafita, 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 Perafita, Portugal
Perafita is located in the Porto District of Portugal, which is characterized by a varied topography. The area around Perafita is mostly flat to gently sloping terrain with some areas of hilly or slightly mountainous terrain. It's situated near the coast, so it has a maritime climate with mild winters and warm summers.
For large-scale solar PV installations, you would generally want flat or gently sloping land that receives a lot of sunlight throughout the year. The coastal areas around Perafita could be suitable for this because they are relatively flat and receive ample sunlight due to their proximity to the ocean.
However, it's also important to consider other factors such as local regulations, access to transmission lines, and potential environmental impacts before deciding on a location for large-scale solar PV. For example, if an area is designated as protected land or if it's home to rare or endangered species, it may not be suitable for development.
A thorough site assessment would need to be carried out by professionals in order to determine the most suitable locations for large-scale solar PV around Perafita.
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.
