Is Solar-powered Lighting a Good Option for Northern Locations?

If we asked you what the best country for a solar-powered light would be, what would you say? Mexico? Australia? Brazil? While a country with a warm climate and year-round sunshine might seem like the obvious answer, if you look at the top countries in the world for solar capacity—Germany, China, and Japan—you’ll notice that […]

Backup Power for Solar Lighting: How Much Is Enough?

One of the biggest perks of solar lighting is that it is self-contained, meaning it doesn’t rely on the grid for power, and it doesn’t require trenching to install. But this perk is only a perk if you understand how solar lighting works, and build your systems to take full advantage of it. Because solar […]

The Evolution of LEDs in Street Lighting

In the span of a decade, LEDs have transformed everything from car headlights to Christmas trees to streetlights. And it makes sense: compared to their conventional incandescent or high-pressure sodium (HPS) counterparts, LEDs use less energy, produce better, more direct light, and last almost seven times as long, resulting in significant cost savings. Given the […]

Sizing Solar Batteries for Optimal Health and Longevity

When it comes to solar lighting, the times you want to use energy are rarely the same as when your panels can produce it. Peak electricity generation typically happens around midday; peak consumption happens after dark. That means that if you want to power an off-grid light after dark, you’re going to need a good […]

Critical Infrastructure and the Rules for Resilient Lighting

It’s no secret that the U.S. electrical grid is in dire straits. Over the past several decades, energy production and consumption have risen steadily, placing an untenable burden on a system that was never intended to carry such a sizeable load. According to the American Society of Civil Engineers’ 2017 Infrastructure Report Card, the lower […]

The Golden Rules of Solar Sizing a Municipal Park, Trail or Streetlight

Operating profiles. Array-to-load ratios. Depth of discharge. There’s a lot to consider when undertaking a large-scale lighting project and it’s easy to feel overwhelmed if you don’t “speak solar.” We’re here to help. Whether you’re evaluating specs and components for a specific project or simply seeking to better understand the technology and benefits of off-grid […]

7 Questions you need to ask before you start your Solar Commercial Lighting Project

When you install a traditional commercial light, you don’t often need to be concerned with whether it will be “bright” enough or will operate continuously because there is an expectation that it will work as specified. You trench, lay cables, connect to the utility, and bam—you have light! However, if avoiding those trenching and utility […]
