NextGen PV Soiling Mitigation
PV soiling monitors are one of the best ways to know when solar panel cleaning makes sense from an economic standpoint. By knowing how much performance we are losing and our PPA values we can determine when the cost of cleaning < the cost of being dirty (performance loss).
Latest Developments and Advances in Marine Energy
It is found that marine energy can be used to generate enough power to meet the energy demands worldwide. To extract energy from the ocean, there are many techniques which include the energy from the waves, energy from currents, salinity gradients, and temperature gradients
Semtive USA Introduces Wind System That Lowers Cost, Improves Roi of Residential and Commercial Renewable Energy
Generating clean energy for a highly competitive levelized cost of energy (LCOE) as low as $0.01/kWh, the Nemoi M can be installed as a standalone system or to optimize solar and energy storage as part of a hybrid renewable energy system.
The Importance Solar Warranties and Customer Service
Historically, the focus has always been on the CAPEX of projects when deciding on one company or another. But what time and experience has shown many clients is that OPEX must also be taken into account in this selection.
Shading Analysis: How To Do It And Get It Right
If you put ten different people up on the same roof with the same handheld shading analysis device or behind the controls of a do-it-yourself (DIY) software platform, you'll most likely end up with ten different results.
American Solar Repair Makes the Switch to the RT-MINI
American Solar Repair has a unique focus in the solar industry: rather than install new solar panels on customers' homes, they remove existing panels on roofs that have leaks or other problems and reinstall the panels using new mounting hardware.
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.

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer
HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
