Cuando Bad Bunny subió al escenario de la Super Bowl, no fue solo otro espectáculo de medio tiempo — fue una declaración de resonancia cultural en el escenario más grande del mundo. Su música está en tendencia porque conecta con la experiencia vivida de las personas, y “El Apagón” no es la excepción.

Pero aquí está lo importante: la canción no es popular solo por su ritmo o su impacto viral. Resuena porque captura algo real y generalizado — una realidad que la gente entiende, ya sea en Puerto Rico o en cualquier lugar donde la confiabilidad eléctrica importa.

Los apagones no son solo una anécdota caribeña.
Son una señal. Un síntoma de sistemas que fueron diseñados para condiciones distintas a las que hoy les exigimos.

En todo el mundo estamos viendo el mismo patrón:

• Redes eléctricas construidas hace décadas
• Nuevas cargas derivadas de la electrificación
• Generación renovable que, por naturaleza, es variable
• Creciente demanda sin una inversión equivalente en resiliencia

Por eso “El Apagón” toca tan de cerca a tantas personas. Aunque la canción se refiere específicamente a los problemas energéticos en Puerto Rico, el sentimiento refleja una tensión universal entre las expectativas y la realidad de la infraestructura.

Esto nos lleva a una pregunta sencilla pero crucial:

¿Cómo producimos más energía sin sacrificar productividad, territorio o resiliencia?

Ahí es donde la energía solar — y especialmente la agrovoltaica — deja de ser una idea atractiva y se convierte en una estrategia práctica.

Energía solar fotovoltaica y resiliencia de la red: una contribución real

La energía solar tradicional cumple un papel en la descarbonización y en el aumento de la capacidad de generación. Pero la agrovoltaica (agricultura + energía fotovoltaica) aporta algo más integral:

No es competencia, es integración.

• La agrovoltaica no le quita la tierra a la producción. Trabaja con ella.
• Los cultivos siguen creciendo
• El ganado continúa pastando
• La tierra se mantiene productiva
• La energía se genera en los mismos lugares donde la gente vive y trabaja

No se trata solo de instalar paneles — se trata de diseñar sistemas que cumplan múltiples funciones al mismo tiempo.

Por qué esto importa en el contexto de “El Apagón”

La canción ha llevado el tema de la confiabilidad energética a la conversación cultural — y eso representa una oportunidad.

Podemos aprovechar ese impulso para avanzar hacia soluciones que:

• Fortalezcan la generación energética local
• Reduzcan la dependencia de infraestructura distante y vulnerable
• Hagan que las redes sean más resilientes frente a eventos climáticos, picos de demanda y cambios estructurales.

La energía solar fotovoltaica — distribuida, bien pensada y combinada con la agricultura — forma parte de la historia de la resiliencia. No es una solución mágica, pero sí es una pieza real de la solución.

La música de Bad Bunny está en tendencia porque refleja una verdad que las personas sienten en su vida cotidiana.
La energía solar y la agrovoltaica merecen estar en la conversación porque ofrecen una forma concreta de enfrentar una realidad que nuestra infraestructura ya no puede ignorar.

La oportunidad que tenemos por delante

La atención hacia los desafíos energéticos está creciendo — tanto cultural como políticamente. El siguiente paso es transformar esa conciencia en cambios prácticos.

La pregunta no es si la energía renovable es necesaria.
La pregunta es si estamos diseñando nuestros sistemas de manera que hagan a las comunidades más resilientes, no más frágiles.

La agrovoltaica no es solo sostenibilidad — es una forma de trabajar con la tierra, con las personas y con los sistemas energéticos para construir un futuro más fuerte y resiliente.

Bad Bunny’s Super Bowl Performance, “El Apagón,” and a Deeper Energy Conversation

When Bad Bunny took the stage at the Super Bowl, it wasn’t just another halftime show. It was a declaration of cultural resonance on one of the largest stages in the world. His music is trending because it speaks to people’s lived experience, and “El Apagón” is no exception.

But here’s what’s important: the song isn’t just popular because of its beat or viral appeal. It resonates because it captures something real and widespread — a lived reality that people understand, whether they’re in Puerto Rico, or anywhere power reliability matters.

Blackouts aren’t just a Caribbean anecdote.
They’re a signal. A symptom of systems that were designed for different conditions than the ones we’re asking them to handle today.

Across the globe, we’re seeing the same pattern:

• Grids built decades ago
  
• New loads from electrification
  
• Renewable generation that’s variable by nature
  
• Growing demand without equal investment in resiliency
  

That’s why El Apagón hits close to home for so many. Although the song is specific to energy issues in Puerto Rico, the sentiment reflects a universal tension between expectation and infrastructure reality.

This leads us to a simple but crucial question:

How do we produce more energy without sacrificing productivity, land, or resilience?

That’s where solar — and especially agrivoltaics — moves from being a catchy idea to a practical strategy.

Solar PV and Grid Resiliency: A Real Contribution

Traditional solar plays a role in decarbonization and generation capacity. But agrivoltaics (agriculture + photovoltaics) brings something more layered:

It’s not competition, it’s integration.

Agrivoltaics doesn’t take land away from productive use. It works with it.

• Crops continue to grow
  
• Livestock continues to graze
  
• Land remains productive*
  
• Energy is generated in the very places where people live and work
  

This isn’t just about adding panels — it’s about designing systems that serve multiple purposes at once.

Why This Matters in the Context of “El Apagón”

The song has put energy reliability into cultural conversation, which presents an opportunity.

We can use that momentum to push toward solutions that:

• Strengthen local energy generation
  
• Reduce reliance on distant, brittle infrastructure
  
• Make grids more resilient to weather, demand spikes, and climate shifts
  

Solar PV — distributed, thoughtful, and combined with agriculture — is part of the resiliency story. It’s not a silver bullet, but it is a real piece of the solution.

Bad Bunny’s music is trending because it reflects a truth people feel in their lives.
Solar and agrivoltaics deserve to be part of the conversation because they offer a real way to address a truth our infrastructure can no longer ignore.

The Opportunity Ahead

Attention to energy challenges is rising, both culturally and politically. The next step is turning that awareness into practical change.

The question isn’t whether renewable energy is necessary.
It’s whether we’re designing our systems in a way that makes communities more resilient, not more fragile.

Agrivoltaics isn’t just sustainability; it’s a way to work with land, people, and energy systems for a stronger, more resilient future.

In the crisp weather of mid-October, our team completed one of the most unique and inspiring projects in our portfolio to date. Set against the dramatic mountain backdrop of Grand Junction, Colorado, this photovoltaic (PV) system marks a major milestone for agrivoltaics in the US. At completion, the structure stands as the largest viticulture-focused agrivoltaic system (or “viti-voltaic”) in the country.

Our Partners

We were proud to serve as the installation contractor under Sandbox Solar, a local EPC and leader in agrivoltaics across the region. The single-axis tracking system was designed and supplied by SolarGik, and spearheaded by Dr. Horst Caspari, a Colorado State Professor and expert viticulturist.

Located near Colorado State University’s Western Campus, Dr. Caspari’s quarter-acre research vineyard of Chardonnay grapes will serve as a living laboratory for the combination of solar energy and sustainable agriculture. Here, researchers will study everything from soil compaction caused from solar installation to shifts in microclimates and how different panel opacities affect light transmission, vine growth, and fruit quality.

Why This Installation Was Different (and Challenging)

As interest in agrivoltaics continues to grow, we have had opportunities to build several agrivoltaic systems. With previous builds, our team worked on blank-slate landscapes, not yet populated with soon-to-be-planted vegetation. In this case, however, our crew was faced with the task of building a PV system within rows of mature, established grapevines. 

Our installation team worked carefully within these vines — driving piles, assembling the racking, and installing 240 solar panels — while avoiding major disruption to the crop. This project called for a new level of planning and adaptability, as we adjusted our usual construction methods.

• The result: a sleek 14-foot-tall steel structure, designed at this height to let the right amount of sunlight in between rows of panels. 

According to the Colorado Newline, the system is projected to generate approximately 155 megawatt-hours of clean electricity per year, supplying roughly 40% of CSU Western Campus’s annual energy needs. But the impact and purpose of this project goes far beyond energy production. As Dr. Caspari stated, this system was designed with an “A before the V” mindset. In agrivoltaics, this means agriculture takes priority over voltaics.

For this particular design, the agricultural benefits include:

• Protection from hail and frost
  • Even a single hailstorm or frost can ruin nearly an entire grape yield. The PV canopy offers an added layer of defense and creates a more temperate microclimate, shielding crops from weather extremes.
    
• Beneficial Shading
  • Partial shading helps moderate soil temperatures, allowing the ground to retain moisture longer and reducing irrigation needs. It also protects delicate grapes from intense solar radiation during the hottest weeks of the summer.

Heading into chilly November, observations already show milder temperatures under the system, confirming the climate benefits of elevated PV systems for sensitive crops like grapes.

Looking Ahead

While the U.S. still has ground to cover compared to Europe’s agrivoltaic movement, this project represents a large step in the right direction. It stands as a living demonstration for how clean energy infrastructure can enhance, rather than compete with, agricultural productivity, and we’re thrilled to have contributed to this advancement.

As more growers and researchers explore dual-use solar, Sunstall Inc. looks forward to continuing our role in building the systems that make this progress possible; from vineyards to orchards to open fields.

As solar technology continues to evolve, one of the most promising developments is vertical photovoltaic (PV) systems. Unlike traditional panels installed at an angle on rooftops or open fields, vertical PV panels stand upright, like a fence, and can be bifacial, capturing sunlight from both sides.

Where Vertical PV Systems Thrive

Vertical solar panels are particularly useful in spaces where traditional installations are limited. Examples include:

• Agricultural land, where panels can coexist with crops, maximizing land use efficiency.
  
• Noise barriers along highways or as property fences, turning otherwise unused vertical surfaces into energy-generating assets.

The Advantages: More Yield, More Flexibility

Vertical PV systems can increase overall electricity generation in certain conditions. Bifacial panels, for example, capture both direct sunlight and reflected light, while vertical placement can optimize energy collection during low-sun periods, such as morning and evening. This “dual-use” potential allows landowners to produce solar power without sacrificing valuable space for other uses.

Considerations and Limitations

While vertical PV offers unique benefits, there are trade-offs:

• Peak midday production is typically lower compared to optimally tilted panels. Whereas vertical produces peak energy in the morning and afternoon, often matching energy demand curves.
  
• Local conditions, such as sun angles, climate, and shading, significantly influence performance. Vertical bifacial panels perform best where there is high reflectivity from surroundings such as sandy or snow-covered ground and in-between greenhouses. 
• Upfront costs, especially for bifacial panels, may be higher, so careful economic analysis is needed. However, preliminary research suggests the potential for long term cost savings due to reduced maintenance needs.

Real-World Applications

Vertical PV systems are already being deployed in innovative ways, such as along airport perimeters or integrated into agricultural projects. These systems showcase how flexible solar solutions can expand energy generation opportunities while maintaining productive land use.

The Takeaway

Vertical photovoltaic panels are not just a concept, they are a practical solution for maximizing solar energy in areas with space constraints or multiple land uses. By creatively adapting vertical surfaces, we can generate more power, optimize land use, and move closer to a sustainable energy future.

If you’re a landowner, business, or farmer interested in exploring vertical solar solutions, now is the perfect time to start. Assess available space, consider dual-use opportunities, and connect with a Sunzaun specialist to see how vertical PV can boost your energy output. Small steps today can lead to big savings and sustainable power tomorrow.

Farmers today are under increasing pressure from rising operational costs and a changing climate, both of which threaten the viability of owner-operated farms. At the same time, the growing demand for food and the renewable energy transition compete for space. But what if farmers could harvest both food and solar power from the same land, while becoming more financially secure? Agrivoltaics, also known as agri-photovoltaics (agri-PV), enables farmers to keep farming, while balancing other demands.

How Agrivoltaics Works

Agrivoltaics (Agri-PV) refers to the combined use of agricultural land for food production and solar power generation by enhancing farm operations rather than replacing them. Agri-PV builds farmer resilience by either a) providing a secondary reliable income source when energy is sold to the grid, or b) reducing on-farm energy-related operational costs by using energy generated by their photovoltaics (PV) system. The article from which this blog was based distinguishes between three Agri-PV systems:

• Overhead Agri-PV
  • PV modules mounted over 6 ½ ft high
  • Protects crops from hail and mitigates heat stress
  • Designed to allow crops, livestock, and machinery underneath
  • More expensive due engineering and installation complexities
    
• Ground-Mount Agri-PV 
  • Allows for machines to operate between rows, not under
  • Lower installation costs
  • May cause uneven crop shading
  • Not ideal for sun-demanding field crops like wheat and corn
    
• Vertical Agri-PV 
  • Modules mounted upright like fences (east-west orientation is common)
  • Bifacial modules, meaning both sides of the panel convert light into energy
  • Space-efficient: good for pastures or as fencing for livestock
  • Allows machinery to operate between rows 
  • Mid-tier costs

Agricultural Benefits and Tradeoffs

Fortunately for farmers, Agri-PV offers more than just economic benefits from solar power generation. These systems can also complement crop production. Solar infrastructure creates microclimates, mitigating the compounding effects of drought, extreme heat, and storms. Shade from the panels reduces evapotranspiration, helping soil retain moisture, an especially important function in arid climates. These protective-like structures can also shield crops from wind damage and heat stress. In fact, research shows that some crops, such as berries, leafy greens, and herbs, can produce higher yields when grown between PV rows.

In orchards, solar structures may even replace traditional hail nets, reducing long-term operational and maintenance costs. Improved crop resiliency under Agri-PV can reduce damage from fungal and bacterial pests, decreasing the need for pesticides.

However, tradeoffs do exist. Uneven shading, particularly from fixed-tilt ground-mounted systems, can lead to non-uniform soil moisture levels. In wetter regions, this may increase the risk of fungal disease if not properly managed. Crops that require a lot of light, like corn and wheat, may also experience reduced yields under shaded conditions. In such cases, vertical systems, like Sunzaun—where shading patterns are less obstructive—are often better suited.

Recent advances in semi-transparent panels are also worth exploring. Semi-transparent panels allow more light to pass through to the crops, enhancing the growth for traditional open-field crops. However, while they reduce below-ground shading, the panels themselves absorb less sunlight, which leads to decreases in energy production. Ultimately, the right system depends on the farm’s goals.

Supporting Farmers – Legal & Economic Context

From an economic stand-point, Agri-PV creates a new, predictive revenue stream. Unlike traditional solar farms, the integration of such systems typically avoids re-zoning farmland as “built-up” areas, which bypasses the need for lengthy planning approvals. Steering clear of re-zoning reinforces the idea that Agri-PV is enhancing farmland rather than replacing it.

In the European Union, Agri-PV systems allow land to remain classified as agricultural, helping farmers maintain access to subsidies. Although there is no nationwide rule that guarantees the same treatment in the U.S., states like Colorado, Massachusetts, New York, and California increasingly recognize agrivoltaics and may preserve agricultural tax status or zoning classifications. In some jurisdictions, installing solar can trigger reassessment unless specific exemptions are in place. It is important to check local zoning laws, property tax codes, and solar/agriculture regulations before moving forward with an Agri-PV project.

A Tool for the Energy Transition

While initial installation costs for Agri-PV systems can be higher, long-term benefits, such as income, climate resilience, and ecological value, often outweigh the investment. The energy sector and agriculture both need to evolve to meet the demands of the future. Agrivoltaics offers an opportunity to meet both demands, while giving farmers the freedom to continue their farming operations.
