In just a few days, we'll be welcoming the team from Dispatch Energy to Adjuntas, Puerto Rico.

We're especially excited to receive this group because their support for Let’s Share the Sun extends far beyond this delegation. Earlier this year, after the loss of critical DOE funding, Dispatch stepped forward with a generous donation to help continue bringing reliable solar energy to vulnerable communities across Puerto Rico. Their leadership was rooted in a simple but powerful belief: that energy resilience is ultimately about people.

Now, we'll have the opportunity to work side by side as they experience firsthand the communities, families, and impact behind this mission. We are deeply grateful for their partnership, their generosity, and their commitment to turning conversations about energy into action.

Welcome to Puerto Rico, Dispatch Energy. We can't wait to share this experience with you.

A glimpse into what resilience looks like.

Yesterday, the Adirondack Solar Alliance were on the ground in Río Grande, Puerto Rico helping complete a solar installation at Hogar de Luz, an elder care facility serving some of the island’s most vulnerable residents. This is the fourth elder care facility supported through the Alliance’s fundraising, volunteer work, and partnership with Let’s Share the Sun.

During our visit, the facility’s director shared that power outages meant oxygen machines stopped working for six residents. Staff had to rely on backup oxygen tanks with only two masks available, forcing them to rotate oxygen between elders while waiting for power to return.

Now, Hogar de Luz has reliable solar and battery backup to keep critical equipment running when the grid fails — bringing safety and peace of mind to both residents and caregivers.

These photos capture the work behind that impact.

A glimpse into our day-to-day at Let’s Share the Sun.

This week, Nancy Brennan-Jordan, Lucas Barreto, Joshua Guthrie, and Rebecca Rodriguez traveled across Adjuntas, Puerto Rico visiting past and future beneficiaries — evaluating homes for new solar installations, checking in on previous recipients, and learning how reliable energy continues to support their health, safety, and daily lives.

The team also visited our longtime community partner Casa Pueblo, whose leadership and vision continue to serve as an anchor for our work and for community energy resilience across Puerto Rico.

These visits are at the heart of our work. Every conversation, every home, and every system checked reminds us that solar energy is about so much more than electricity — it’s about resilience, care, and community.

What does impact actually look like?

For elder care facilities in Puerto Rico, it looks like lower utility bills, stronger resilience, and more resources staying where they belong: with residents. Through our partnership with Adirondack Solar Alliance, we’ve helped bring solar energy to elder care facilities serving some of Puerto Rico’s most vulnerable communities.

So far, that includes:
☀️ Hogar Cabecitas de Oro
☀️ Hogar Leila Raquel
☀️ Hogar Sustituto Jacqueline Serrano

With more to come:
☀️ Hogar de Luz
☀️ Hogar Elizabeth

At Hogar Cabecitas de Oro, monthly electricity costs dropped from approximately $1,200 to $200 after solar installation, creating an estimated $12,000 in annual savings.

At Hogar Leila Raquel, solar has generated approximately $860 in monthly savings, or over $10,000 annually, while also strengthening the facility’s ability to maintain reliable care during grid instability and outages.

At Hogar Sustituto Jacqueline Serrano, solar energy is generating approximately $3,100 in annual savings, helping reduce operational costs while increasing energy resilience for residents and staff who depend on uninterrupted care every day.

We are deeply grateful to for helping make this work possible, and excited for what comes next.

After Hurricane Maria, Puerto Rico’s official death toll was initially reported as 64 lives lost. But as the dust settled and independent research examined the true aftermath, a far more devastating reality emerged.

A study commissioned by the Government of Puerto Rico and conducted by George Washington University estimated 2,975 excess deaths in the six months following the storm. Harvard researchers later estimated the number may have been even higher: 4,645 excess deaths.

These were not just deaths caused by wind or flooding. They were deaths linked to prolonged power outages, interrupted medical care, delayed emergency response, spoiled medications, failed medical equipment, and the collapse of essential infrastructure.

For older adults, the consequences were especially severe. Many rely on electricity not as a convenience, but for oxygen support, refrigeration of medications, mobility assistance, cooling during extreme heat, and access to ongoing care. When the power grid fails for weeks or months, medically vulnerable communities are pushed into impossible circumstances.

This is why resilient energy solutions matter. For Let’s Share the Sun, solar energy paired with battery storage is more than clean technology. It is a tool for protection, continuity of care, and resilience. In elder care facilities and medically vulnerable communities, reliable energy can help ensure critical services continue when the grid does not.

Meet Maddie Weller!

This summer, Maddie joins Let’s Share The Sun as an intern. But before that, she was already part of the LSTS community.

In her own words:

“My name is Maddie Weller and I am from Cleveland, OH. I am a third-year undergraduate student at Georgia Tech studying Environmental Science with a minor in Energy Systems. My academic interests span climate science and environmental justice, including greenhouse gas emissions reduction, air pollution mitigation, renewable energy, and energy equity. I am passionate about implementing climate solutions that are beneficial for environmental health and address systemic injustices in energy supply and accessibility.

Outside of my academics and professional interests, I enjoy running, hiking, reading, playing the piano, and photography.

I was introduced to Let’s Share the Sun last summer, when I immediately connected with the organization’s holistic mission of utilizing renewable energy technologies, specifically solar panels and battery storage systems, to address complex community issues, including health, utility reliability, climate resilience, and financial stress.

Initially, I participated in the Student Advisory Committee, which connected me to students from universities across the country working to establish chapters supporting Let’s Share the Sun. I was inspired to create a similar program at Georgia Tech.

I am incredibly grateful for and humbled by the opportunity to travel to Adjuntas, Puerto Rico, to assist with the Duke University solar installation, which offered the unique experience of hearing the stories of residents living with life-threatening medical conditions amidst multi-month electricity outages. I am excited to carry this momentum into the fall at Georgia Tech!”

We’re so excited to have Maddie as part of the LSTS team and can’t wait to see where this momentum leads.

Not every classroom has four walls.

Students from Duke University’s Nicholas School of the Environment traded lectures for ladders, case studies for rooftops, and conversations about sustainability for the lived reality of energy insecurity in Adjuntas, Puerto Rico.

There’s a world of difference between talking about energy access and standing on a roof helping make it happen. This installation was for a family where losing power isn’t just inconvenient; it can disrupt care, routines, and peace of mind. For households already balancing health needs and financial strain, energy resilience becomes deeply personal.

To the students: thank you for showing up with curiosity, compassion, and a willingness to learn beyond the textbook. And to the faculty who helped make this experience possible, thank you for creating opportunities that connect education with action in such a tangible way.

There is something powerful about watching the next generation engage with these issues not as abstract environmental conversations, but as human ones.
