Off-grid, grid-tied solar power

Elevated Racking Structure in Bordentown, NJ

Largest continuous elevated racking structure in the United States

This 1MW DC grid-paralleled Solar System in Bordentown, NJ is the largest

continuous elevated racking structure in the United States. The system will

provide clean and low-cost power for onsite business operations for the next

20 to 25 years. As part of the Renewable Energy Portfolio available only in New

Jersey, our customer was able to lower the system cost through the sale of

environmental attributes (Solar Renewable Energy Credits).

This 1MW grid-tied solar power system includes 5,880 photovoltaic panels

spanning a total area of 140,000 square feet. The panels are tied in to one single

electric utility meter via 10 separate inverters; this ensures that if a single array

needs troubleshooting, 90% of the system would still be producing electricity.

The system will generate more than 1,130,000 kilowatt hours per year, which is

roughly the amount required to power 128 homes. The resulting CO2 offset of

2,030,000 lbs (about 923 tons) is equivalent to eliminating the annual emissions

from 169 cars.

Off-grid Solar System in Hinsdale, CO

Remote electrical system in Southwestern Colorado

This remote electrical system was built and installed in Southwestern Colorado

as part of a project to improve emergency communications. The site is located at

9700 feet elevation up a narrow and steep ATV path. An 800mHz repeater radio

is the primary load on-site with additional DC and AC power provided for local

emergency ﬁre, rescue and police communication.

The combined load of all the communications systems is just over 50 kilowatt

hours per day – roughly equivalent to the electrical demands of two average grid-

connected homes. Not surprisingly, the mandate for this electrical system was

"extreme reliability" so two sources of power generation are available. A 13.86kW

PV array is the primary source of energy, backed up by a 20kW

diesel generator.

The solar power system on this site is intended to meet 86% of the power

requirements, with the remainder of the power coming from the 20kW diesel

generator. The 240Vac output of the generator is converted into 48Vdc by a bank

of Argus Cordex™ 3.6kW rectiﬁers. The hybrid nature of this system – PV assisted

by a generator – maximizes battery life and minimizes the risk of load loss.

Grid-tied Solar System in Phoenix, AZ

153kW grid-tied solar power system

As part of a broader effort to reduce their power demand and energy expenses,

Cox Communications contacted Alpha Energy to design and implement a solar

power system at its Phoenix, Ariz. headquarters. Alpha Energy worked with a

regional prefabricated parking structure installer and electrical contractor to engineer

and build a series of turnkey Elevated Racking Structures

The 153kW grid-tied solar power system includes 900 photovoltaic panels spread

across six new racking structures, enough to accommodate 75 parking spaces.

The system will generate more than 240,000 kilowatt hours per year, which is

roughly the amount required to power 16 homes. The resulting CO

offset of

392,081 lbs (178.2 tons) is equivalent to preventing the emissions from 33 cars.

As an added beneﬁt the racking structures provide parking protection from the

elements. These structures also make the solar modules visible from the street to

help demonstrate Cox Communications' commitment to renewable energy.
