Solar Power at Senda de Vida 2: Building Infrastructure That Lasts

Reynosa, Tamaulipas, Mexico

At its peak, Senda de Vida 2 was home to more than 3,000 displaced people. Today, fewer than 20 people live at the shelter. The population changed. The need for the shelter's infrastructure did not.

Our local partner still operates and maintains the site, so electricity, water, and upkeep costs continue even when fewer people use the space. In 2025, Solidarity Engineering installed a solar power system to cut one of those ongoing costs. In its first 11 months of operation, it produced 24,100 kWh and saved an estimated $66,400 MXN (about $3,620 USD).

The Challenge: A Shelter Still Needs to Operate

Senda de Vida 2 is more than a collection of buildings. It's infrastructure that has to stay functional and ready to respond to changing patterns of displacement.

Before the solar installation, electricity was a major recurring expense. A March 2025 CFE electricity bill totaled $11,158 MXN, about $608 USD. For a partner maintaining a large shelter site, cutting that bill makes a real difference.

The Solution: Solar Infrastructure

Our team installed the solar panel system at Senda de Vida 2 in March 2025, and it began producing power for the shelter in October 2025.

The gap between those two dates was paperwork, not engineering. To connect to the grid, the shelter needed a bidirectional meter from CFE, Mexico's federal electric utility. A bidirectional meter measures power flowing both ways: what the shelter draws from the grid, and what the panels send back. The approval process took about seven months.

Infrastructure projects don't always move at the speed of installation. Permitting, utility coordination, paperwork, monitoring, and follow-up matter as much as the construction itself.

One Year of Results

Since the system began operating in October 2025, it has produced 24,100 kWh of electricity, based on the inverter's actual reading, and saved the shelter an estimated $66,400 MXN (about $3,620 USD).

For our local partner, the value isn't just the electricity generated. It's an ongoing operating cost that got smaller, month after month. Production climbed with the spring sun once repairs were done, and the system is now in its strongest stretch yet.

Infrastructure Is Never Completely “Finished”

On March 16, 2026, strong winds damaged about eight panels and reduced the system's output for two to three weeks. The system was restored by April, and production has stayed strong since.

The incident was a practical reminder of something we see across our work: installing infrastructure isn't the end of the relationship. We stay connected with local partners after projects are complete. When something breaks or needs troubleshooting, we help diagnose the problem and figure out what comes next.

For this project, that support has been led by José, Solidarity Engineering's resident electrical engineer and solar expert. José has been involved from the start, through the original installation and CFE connection, performance monitoring, and troubleshooting after the wind damage.

Why Ongoing Support Matters

Humanitarian infrastructure has to work in real conditions: weather, changing populations, utility requirements, and the maintenance a large site needs over time.

A system can be technically sound on installation day and still run into problems later. Panels get damaged, equipment needs repair, utility requirements change, and a partner's needs can look very different a year on. That's why we don't treat infrastructure as a project with a clear end date. We see it as part of an ongoing relationship with local teams.

Building for What Comes Next

Senda de Vida 2 looks very different today than it did when more than 3,000 people lived there. But displacement is unpredictable. A shelter serving a handful of people today may need to hold hundreds or thousands again, and the infrastructure that makes that possible shouldn't have to be rebuilt from scratch every time a crisis shifts.

The solar system at Senda de Vida 2 is one small example of what that looks like in practice. It cuts an ongoing cost for our local partner, keeps essential infrastructure running, and helps preserve the shelter's capacity for whatever comes next.

That's the kind of infrastructure we want to build: it meets needs today, reduces ongoing costs, and keeps working long after the installation crew goes home.
