Modeling Microinverters and DC Power Optimizers in PVWatts
PVWatts performs simplified PV system performance calculations using information about the arrays geographic location, orientation, and a set of user-input loss factors
Is Home Energy Storage Coming to your House?
Home energy storage helps whichever energy source is the cheapest, and helps the grid stay stable and available to us all.
Solar Heating Combined with a Ground Heat Pump Is a Cost-efficient, Ecological Solution
Solar power was particularly efficient when combined with ground heat in terms of the profitability of investments.
Solar Powered Water Pumping: Combining two hot topics, Water and Solar
A solar powered water system is one of the easiest solar power systems to install and will ultimately save you time and money.
ABB and Smart Grid Technology in North Carolina
North Carolinas Renewable Energy Portfolio Standard (REPS) has encouraged investments in renewables and the energy economy statewide.
5 Things You Should Know Before Installing Solar Panels
Pay too little and you risk a dodgy product and no after-sales service. Pay too much and youll end up waiting 10 years just to recoup your cost!
Ports/Trains - Great Non-road EV Opportunities for Utilities
Unlike on-road electric vehicle programs which can be complicated and depend, in part, upon factors outside a utilitys control, non-road programs are less risky and comparatively simple to design, operate, and control.
Case Study: Solar Tile Mount Provides Adequate Air Flow Between Solar Panels And Tile Roof
TRA Snow and Sun modifies Solar Tile Mount to adjust vertically for use on S-tile tile roofs to provide adequate air flow between solar panels and the tile roof.
Hawaii and Vermont set high renewable portfolio standard targets
Two states recently passed legislation that would require significant increases in renewable electricity generation.
Digital Inkjet Printing: An Opportunity for Further Reductions in Solar Energy Costs
With solar on the cusp of economic feasibility in many areas, incremental cost reductions such as those offered by digital inkjet printing technologies can make the difference between moving ahead with solar and sticking with electricity from the local utility
Vanadium Flow Batteries for Global Academy of Technology (GAT) College
By implementing the IMERGY storage solution in the premises, GAT is able to store the energy produced by the PV panels during the day and use it during the non-solar time, thus eliminating the diesel generator run to provide clean power when needed.
Ultracapacitor Usage in Wind Turbine Pitch Control Systems
Ultracapacitors have other significant advantages compared to batteries such as high power density, high efficiency, long service life, predictable aging, wide operating temperature range and light weight.
DIY: Don't Install Yourself
A professional installer will make sure you take the steps needed to take advantage of any incentives that may be available to you (most of which require the installation be handled by a professional)
Crude Oil's Impact on Renewable Energy: Energy Alternative or Energy Staple?
With the removal of fossil fuel subsidies and the continual drop in capital costs in renewables technology, the margins for the leading players in the renewables industry will increase.
FastRack510 Installed at Hawaii's Largest Airports
The airports are not only in hurricane prone regions, but also in areas of high seismic activity. The minimal seismic anchors were installed at a rate of up to five per man hour.

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.
