Five Myths About DC Power Optimizers
While it is very common for solar installers in the U.S. to install so-called power optimizers in PV systems to meet the local electrical code requirements, these devices are subject to considerable controversy in the rest of the world.
A Deep Dive Into Improving The ROI For Commercial PV Solar Systems
As with any investment, the two main ways to improve the ROI of a commercial PV system is to increase energy production (and therefore annual revenue) and decrease lifetime costs. Let's take a deeper look at how this can be done in commercial PV installations.
Monetize That Runway!
Public airports across the U.S. face a similar challenge: a fixed revenue model with limited opportunity for growth. Fortunately, many have an untapped resource that they can turn into a source of predictable, long-term income - the open space around their runways.
How Keeping It Simple Can Lower O&M Costs
To mitigate the increasing cost of running a utility-scale solar project, many owners and operators have switched their focus from CapEx to operations and maintenance (O&M).
Experts Forecast the Wind Plant of the Future To Be Taller and More Economical
In the most-likely scenario, the experts predicted that hub height for newly installed onshore wind turbines will reach 130 meters in 2035, rather than the 115-meter forecast offered in a 2015 survey.
Operating Principles for Lead Acid Batteries
GEL, AGM (Absorbed Glass Mat), and Flooded batteries are all lead-acid batteries. The primary difference is how the electrolyte is handled. Each type of battery has its own optimal charging characteristics.
Solar Training Courses for 2022
SEI is scaling the organization on several fronts to give people more access to hands on, more classes online, and more services for employers to help bridge the gap between training and employment.
Agrivoltaics: The New Frontier
The pairing of photovoltaics and agriculture is something that must be further explored, including more supportive legislation and regulations allowing for this dual use of land.
Rooftop Solar's Unspoken Truth: Fires and Safety Risks are Uncomfortably Common
Due to inconsistent installation practices, intense manufacturer competition, and sometimes conflicting motives between Operations and Maintenance (O&M) providers and end-owners, the risk of fires looming on rooftop installations is uncomfortably common.
Making Solar an Even Safer Investment
As more businesses, utilities, and state bodies look to solar energy to help them meet their carbon reduction goals and cut energy costs, safety is coming under ever more scrutiny.
New Legislation on PFAS May Affect Your Fire Suppression System
One of the primary problems with PFAS is their "persistence." Persistence means they can persist in soil, water, and in the human body … for years. Exposure to water, air, and sunlight does little to degrade them, thus they are known as "forever" chemicals.
A Tiny Plexiglass House Featuring RT-MINI Closes Deals on the Spot
"I wanted my customers to see the product up close for themselves, not just view an iPad demo," he said. "So, I built a tiny house using plexiglass and mounted RT-MINI II on the roof."
Digitizing the Energy Transition: How Are Digital Technologies Accelerating Decarbonization?
With growing energy demand and increasing focus on energy security and supply resiliency, governments and businesses alike have turned to digital strategies to shape the new energy landscape.
Custom Installation Creates Net Zero SoCal Home
This project, like most, came with its share of challenges and requests from a discerning homeowner who wanted top quality. The ask: plan and install a solar system to handle the high electricity needs of this large home with a customized design and clean aesthetics.
Transition To Clean Energy With Vanadium Battery Technology
A successful transition to clean energy requires safe, cost-effective, and reliable energy storage systems. Such storage systems will also be necessary to improve the efficiency of the electrical distribution grid by reducing power surges and balancing the load over time.
