Renewable Energy

Before solar became an industry, before grid-tied systems, incentives, or sleek lithium batteries, power resilience meant figuring things out yourself. This episode traces the real origins of Alexis Lewis’s solar and electrical expertise, starting not in New York City, but in Antigua, where frequent power outages made energy independence a necessity not a trend. In the early 1970s, when Alexis’s f...

Experience is often reduced to job titles, certifications, or years on a résumé. But in the real world especially in construction and solar experience is something very different. In this episode, Alexis Lewis, founder of Wadadli Solar LLC, breaks down what real experience actually looks like and how it is built long before someone ever installs their first solar module. Alexis shares how growing...

Most solar projects don’t fail on paper. They fail on the roof. In this episode, Alexis Lewis breaks down one of the most common and most expensive disconnects in commercial solar: the gap between spreadsheet assumptions and physical reality. Financial models are clean. Roofs are not. Owners, developers, and even EPCs often rely on high-level feasibility spreadsheets to green-light projects. Watts...

Most commercial property owners track revenue per square foot inside their buildings but almost none measure the financial potential sitting right above them. In this episode, Alexis Lewis breaks down how commercial and industrial roofs should be evaluated not as maintenance liabilities, but as revenue-generating infrastructure. This is not a sales pitch for solar panels. It’s a practical framewor...

For the past decade, solar has often been sold backwards. Not as critical energy infrastructure but as a financial product wrapped in tax incentives, accelerated depreciation, and performance assumptions that rarely get stress-tested in the field. In this episode, I break down a hard truth that many asset owners, developers, and investors are only now confronting: Solar is energy first. And energy...

Across much of Africa, the energy conversation jumps between two extremes: utility-scale power on one end and small solar lanterns on the other. What’s often ignored is the “missing middle” small businesses, clinics, farms, workshops, and community facilities that need reliable power but fall outside traditional grid and donor models. In this episode, we examine how second-life solar equipment rep...

For years, businesses have been trained to lease intelligence monthly subscriptions, per-seat licenses, usage caps, and opaque black-box models that quietly extract value while locking you into someone else’s roadmap. In this episode, we break that cycle. This is a deep dive into why leasing AI is strategically dangerous and how operators, engineers, and business owners can build, own, and control...

Solar systems rarely fail all at once. What actually happens—especially on commercial rooftops is slow, quiet performance drift. Energy output tapers off, alarms stay silent, and asset owners don’t notice until revenue losses are already baked in. In this episode of The Deep Dive, we break down Solar Delta Analysis a practical, field-tested method for identifying performance degradation early by c...

In this episode, Alex breaks down a real-world operations and maintenance issue that many solar system owners and technicians eventually face: a frozen or unresponsive solar inverter. Using field experience from commercial and distributed generation sites, this episode explains what a “hard reset” actually means, when it’s appropriate, and when it’s a waste of time or worse, a risk to the system....

On this episode of Deep Dive, we walk through a real 750 kW DC ballasted rooftop project in New York City that went sideways the moment boots hit the roof. A surprise air-handling unit appears where the solar drawings showed clear space, triggering a high‑stakes clash between the solar crew and the mechanical team. Using field notes from Alexis Lewis of Wadadli Solar, a senior construction project...

Solar tracking is often marketed as a breakthrough in modern solar design but is it really innovation, or just recycled technology with a new sales pitch? In this episode, we cut through the hype and take a hard look at solar tracking systems through the lens of engineering history, operations, and long-term performance. The core technology behind today’s trackers motors, sensors, control algorith...
