Solar PV Analysis of Carpina, Brazil
Carpina, Pernambuco, Brazil is an excellent location for year-round solar energy production due to its tropical climate where sunlight is consistent throughout the year. The amount of electricity produced by solar panels varies slightly by season but remains relatively high all year round. In Summer, each kilowatt of installed solar can produce 6.24 kilowatt hours (kWh) per day; in Autumn it's 5.57 kWh/day; in Winter it's 5.14 kWh/day and in Spring it's 6.76 kWh/day.
The best times of the year to generate solar at this location are during the Spring and Summer, when daily energy output is highest due to longer daylight hours and more direct sunlight.
For a fixed panel installation at this location, tilting the panels at an angle of 7 degrees North will maximise total yearly production from the solar PV system.
However, there could be some local factors that may affect solar production at this location. For instance, Carpina experiences a rainy season which may reduce sunlight exposure on certain days or periods during the year - reducing potential energy generation during these times.
Furthermore, if there are any large structures or trees near your property that cast shadows over your panels for significant portions of the day, they could also impede your system’s performance.
To overcome these challenges:
1) You can install a tracking system that moves your panels to follow the sun across the sky throughout each day which would maximize their exposure to sunlight despite weather conditions.
2) You can ensure there are no obstructions like tall buildings or trees blocking direct sun exposure on your panels.
3) Regular maintenance including cleaning and checking for damages will help keep them working efficiently.
4) Consider installing battery storage systems so you can store excess power generated during peak periods for use when generation is low (such as during rainy days).
Overall though given its tropical climate with ample sunshine most of the time - Carpina, Pernambuco, Brazil is a very good location for solar energy production.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 3161 locations across Brazil. 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 Carpina
Seasonal solar PV output for Latitude: -7.8175, Longitude: -35.3307 (Carpina, Brazil), 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 7° North in Carpina, Brazil
To maximize your solar PV system's energy output in Carpina, Brazil (Lat/Long -7.8175, -35.3307) throughout the year, you should tilt your panels at an angle of 7° 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 Carpina, Brazil
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 Carpina, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 8° South in Summer | 14° North in Autumn | 24° North in Winter | 2° 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 Carpina, Brazil
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 Carpina, Brazil.
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 Carpina, Brazil
Carpina is located in the state of Pernambuco, Brazil. The topography of this region is characterized by a mix of flat and hilly areas. It's part of the Atlantic Forest biome, which means there are many forested areas around. The area also has several rivers and streams.
The city itself has an urbanized environment with buildings, roads, and other infrastructure. However, outside the city limits there are more open spaces with agricultural lands and forests.
In terms of solar PV suitability, large scale solar projects require large amounts of land that are relatively flat for optimal installation and operation. Therefore, the flatter regions surrounding Carpina would be more suited for such projects.
Furthermore, solar PV systems require plenty of sunlight to generate electricity efficiently. According to climate data for Carpina (and most parts of Brazil), it receives ample sunlight throughout most parts of the year which makes it very suitable for solar power generation.
However, a detailed site assessment considering factors such as land availability/ownership status, proximity to transmission lines or substations (for connection to grid), environmental impact assessments etc., would be necessary before deciding on specific locations for setting up large-scale solar PV installations.
Please note that while topography plays a role in determining suitable sites for solar farms; local regulations regarding land use must also be considered along with factors like soil stability and biodiversity impacts.
Brazil solar PV Stats as a country
Brazil ranks 13th in the world for cumulative solar PV capacity, with 13,708 total MW's of solar PV installed. This means that 2.50% of Brazil's total energy as a country comes from solar PV (that's 31st in the world). Each year Brazil is generating 64 Watts from solar PV per capita (Brazil ranks 47th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Brazil?
Yes, there are several incentives for businesses wanting to install solar energy in Brazil. The Brazilian government offers a range of tax credits and other financial incentives to encourage the adoption of renewable energy sources such as solar power. These include reduced import taxes on solar equipment, accelerated depreciation of investments in renewable energy projects, and preferential financing from public banks. Additionally, some states offer additional incentives such as subsidies or grants for businesses that install solar systems.
