Off-Grid Power Systems

Off-grid power systems derive all their power directly from the sun. Potential uses for off-grid can include powering a radio-transmission tower in Mozambique or also powering a security camera at your local seaport. Since these systems are not connected to any external power grid, you are free

to place them in any location there is sunlight. There is no need to dig trenches to extend power lines or call the electric company for a new meter. Systems can even be moved with relative ease, in comparison to grid-tied electrical systems.

All of our solar stand-alone and solar/generator hybrid power systems are pre-engineered with the optimal combination of solar power and battery storage to ensure highly reliable operation in the best of environments. In addition to our standard line of systems, our staff of engineers are available to design custom configurations for a full range of telecommunications, telemetry, cellular, wireless data, flow monitoring, cathodic protection, security lighting, traffic applications and complete village power systems worldwide.

>

Remote Solar Power Systems

Alpha Energy Solar Power Systems (SPS) derive energy from the sun to provide 12, 24 or 48Volt electricity. The energy collected by the photovoltaic array supplies the necessary load while also storing energy in a bank of industrial-grade, maintenance-free, deep cycle batteries. The battery bank then powers the system after the sun goes down.

>

Remote Hybrid Power Systems

Hybrid Power Systems (HPS) incorporate multiple power generation sources to provide redundancy and ensure power in critical situations. By incorporating an AlphaGen™ generator, an HPS system is able to compensate for larger power load requirements and/or obstructed weather conditions, like cloud coverage or low sun exposure.

Remote Hybrid Power Systems

Mozambique Case Study

>

Powers a series of microwave telecommunications sites

>

No generator or utility grid connection

>

Designed with simplified maintenance due to remote locations

This is the site of a microwave backbone, rural radio and external line plant in the northern province of Tete in Western Mozambique.

Thirteen hybrid power systems (HPS), installed on mountain tops in rural Mozambique, power a series of microwave telecommunications sites. The HP systems operate with no generator or utility grid connection, and power microwave repeaters that provide initial and upgraded service to more than

175000 square kilometers. Supplied by Alpha Energy and Argus

Technologies, members of The Alpha Group, the system was designed with simplified maintenance and troubleshooting in mind, considering the remote locations.

The HPS48 Series PV arrays range in size from 660 to 4950W.

Battery charging controllers provide remote access via an RS-232 serial port, allowing engineers to monitor system operating parameters such as PV current and battery voltage. The controllers also provide programmable alarm contacts to alert maintenance crews if battery voltage drops below critical levels.

The system runs on a charge-by-day/discharge-by-night cycle; fully charged batteries can run for approximately six days, ensuring loads are powered during cloudy periods.

Grid-Tied Commercial Systems

Grid-tied and commercial solar systems are appropriate for large businesses, schools, hospitals and government agencies. Being hooked into the utility company, these systems allow you to keep track of the kilowatts used on an hourly basis and store the energy you don’t use. The goal of grid-tied systems is to produce as much power as you use.

Commercial solar electric power systems help to ensure a source of clean and reliable power.

Rooftop systems are a visible display of a company’s commitment to green power. They offer businesses the greatest benefit from solar power, as maximum utility prices coincide with the maximum electrical solar power output.

Alpha Energy provides complete project design and installation services for large-scale PV projects. Our staff offers a range of services including: systems engineering, installation, system commissioning, project management, on-going service support, utility interconnection and self-generation approval. Alpha Energy serves as the primary contractor, carrying the required insurance and bonding.

These systems are ideal for schools, hospitals and government agencies as they demonstrate the environmental, economic and energy benefits of solar electricity.

Alpha Energy provides a range of PV systems for public sector and not-for-profit applications (i.e. schools, hospitals, environmental organizations and national parks) that offer clean electricity and ensure predictable power rates. Alpha’s “Solar Schools” program provides schools across the nation with complete PV systems, along with educational curriculum materials, teacher training and data monitoring systems.

Each of the 3-story apartment buildings received a total of 34kW of PV, with each individual apartment unit receiving its own 900W grid-tied PV system. Another 5kW was installed atop the clubhouse building. Each system was individually metered and supported by its own inverter.

Once completed in 2003 the solar electric systems installed allowed homeowners to rely on the sun for about 80% of their electric needs.

To complete this project, KD Development, a leading San

Diego homebuilder, teamed up with Alpha Energy (Altair

Energy at the time) and BP Solar. In addition to working with

KD’s project architects and engineers for project design and integration, Alpha provided integral support to KD for PV project permitting and interconnection approvals with the

City of San Diego and SDG&E.

With Alpha’s support, KD Development encouraged the broader construction community in San Diego and Southern

California to take a serious look at solar electricity.

1600 Modules in four independent power systems

Aerial view of Loma Linda

The city of Loma Linda, California, has wide recognition as an innovative model for municipality-sponsored technology.

In fact, it was the first city in America to mandate an optical fiber and structured-wiring building code for all new home and business developments. In Summer 2006, the city government of Loma Linda began working with Alpha Energy to design and install an aggressive solar power system that would provide energy to all city buildings including the local senior center, Civic Center, Fire Station and Library.

Now completed the 267kW solar power plant provides over

430MWh of electricity annually—enough to power 35 homes.

Solar modules for the system are mounted on the roofs of four City buildings and on shade structures covering parking spaces in the Civic center complex. Used in this way, the solar modules serve two purposes: first they generate electricity from the sun’s heat for community use, and second they keep the sun off buildings and cars making them easier and less expensive to cool. The construction phase of the project was led by Alpha Technologies Services.

In addition to the solar portion of this project, Alpha Technologies is providing a broad array of backup powering products for

Loma Linda’s optical fiber to the home network and designing

DC plants and inverter solutions for both Headend and point of presence (POP) sites.

The solar power system reduces thousands of pounds of carbon dioxide emissions that would have been produced by coal or gas fired power plants.

The systems performance is tracked by an advanced status monitoring system that transforms raw energy data into a dynamic dashboard view. This interface provides live and historical views of the energy being produced, consumed and returned to the grid.

Alpha Energy’s solar shade parking structures are parking canopies with a roof, specifically designed to provide low-cost support for a solar system. Solar shade structures offer a dual benefit: shading for cars and solar production. A visible display of commitment to renewable energy, the solar shade structures can be used throughout the day and can be complimented with lighting and security features to be used at night as well.

With over 1.2 Megawatts of projects involving solar shade structures, Alpha Energy has gained a good amount of experience in designing and installing such structures.

Structures can be customized aesthetically to match the color and design of buildings and size-wise to fit standard

and complex parking lots.

When roof space isn’t available, or when a building has uncertain structural integrity, installing solar shade structures ensures the security of a long-term renewable energy investment. Not to mention that the financial rebates and incentives used for large commercial solar systems are as well applicable for solar structures, and significantly reduce the total cost of the solar installation.

This 10 acre horse ranch in Arizona features a 4.4kW photovoltaic system. The UPS system is utility connected with 9 essential circuits backed up with twelve 100Ah batteries, ensuring the power remains on during an outage. The carport style roof mounted array offsets current electric costs and guards against utility outages, by storing over 30Hrs of electricity. This UPS system is ideal for this rural location because frequent blackouts leave the ranch without power to pump much needed water to thirsty animals. Since the system’s installation in the Spring of 2004, the Eberhard’s report no more troublesome power outages, and their electric bills have been significantly reduced.

Most utilities allow you to send any excess energy you produce back to the power grid at retail rates– in a process called net metering

Investments in grid-tied solar systems are rapidly increasing in many states throughout the US. Rising electricity prices, increased incentives, improved technology and lower costs make solar systems a more attractive investment than ever before.

Net metering is another factor why so many businesses are changing solar power. Under net metering, you receive retail credit for all of the electricity you generate that you can use to lower future bills or offset nighttime power use. In other words, using net metering allows you to “zero-out” your bill – you can rest assured your power won’t be wasted.

Starting January 1st, 2009, Federal incentives can offset 55% of your solar system’s cost. With a 30% Commercial Federal

Tax Credit and up to 34% Accelerated Federal Depreciation, now is the time to install solar. Residential systems also have a non-capped 30% federal tax credit.

What is a Power Purchase Agreement?

Once the decision has been made to go solar, you can either purchase the system outright, or you can take advantage of our

Power Purchase Agreements.

Zero-Down financing option is for renewable energy systems.

As part of the agreement, Alpha Energy provides system maintenance, predictable rates, and pay-as-you-go bills. A

PPA is a great way to bring solar power to your organization without the upfront expenses.

How it Works.

Power Purchase Agreements provide Third-Party Financing for

300kW* or larger solar systems. Alpha Energy’s partner, who can be a financial institution, owns, installs and provides 100% of the maintenance for your solar system. You will need to purchase solar electricity at a fixed rate with a known escalation factor, only when the system is producing power. Contracts can be for the life of the system, or for a shorter term with the option to purchase at a reduced price at the end of the term.

Contact your Alpha Energy Sales Representative for more information.

* System Size Requirements may very based on site-specific conditions

>

Key factors in evaluating Power

Purchase Agreements:

Benefits of Power Purchase Agreements

Government bodies, colleges, and non-profits can take advantage of federal tax

incentives – the PPA provider owns the system and collects incentives.

No upfront capital cost

No maintenance costs

The customer can install a larger solar system – the system is sized to offset most

of their electricity bill and/or populate all available space.

Predictable energy rates for the length of the PPA term.

Opportunity to purchase the solar system at a reduced cost in the future, or

extend the length of the PPA.

Benefits of An Outright Purchase

Upfront purchase usually has the best financial returns over the lifetime of the

system. Fewer project partners means less overall cost.

Upfront purchase works for systems of all sizes in all states.

If desired, Alpha Energy can provide extended maintenance contracts.

Alpha Energy’s Third-Party Financing Partner may, or may not, be able to

offer a price per kilowatt-hour lower than a customer’s current bill. While

California, Oregon and Hawaii are able to offer PPAs at or below utility rates,

in other states, customers may pay a premium.

Photovoltaic Modules

The most important and visible elements of any solar power system are the solar panels. This is where the initial process of converting the sun’s heat to usable energy begins.

The two main types of solar photovoltaic cells are Monocrystalline and Polycrystalline, that can be distinguished by their color. The production of monocrystalline cells involves extracting monocrystalline rods from melted silicon and then sawing them into thin plates, the resulting color being close to black.

For the production of polycrystalline cells, liquid silicon is poured into blocks that are subsequently sawed into plates, turning the color light blue. The differing production processes lead to different results: While monocrystalline cells have the highest efficiency, polycrystalline cells are relatively more cost-efficient.

In order to provide more or less power for different applications, PV cells can be connected together to form larger units. In general, cells connected in series have a higher voltage and those connected in parallel produce more current.

Silicon solar modules use breakthrough technology perfected by nearly 40 years of manufacturing technology. These modules use a textured cell surface and tempered glass to reduce reflection of sunlight. The anti-reflective coating provides a uniform color and increases the absorption of light in all weather conditions. These solar modules can be applied in many areas including building roofs, photovoltaic power plants, telecommunication hubs, weather stations, broadcast towers, navigation marks, railways and road intersections.

Solar Inverters

Solar inverters convert DC power generated by photovoltaic modules into high quality utility grade AC electricity. Unlike DC to AC inverters used in off-grid applications, no batteries are necessary for these inverters. When the sun is shining, your electricity comes from the PV array, via the inverter. If the PV array is making more power than you are using, the excess is sold to the utility through an electric meter. If you use more power than the PV array can supply, the utility makes up the difference.

At Alpha Energy, we select from a wide variety of solar inverters in the market to ensure that our customers get the most efficient and cost effective inverters for their unique application. All of the grid-connected solar inverters provided by Alpha Energy are at least 95% efficient over their weighted operating range. Many of our inverters have additional features and options including the ability to run in multi-networked applications and communicate via Internet with system operators. Thousands of solar inverters worldwide are connected and active on a daily basis, converting solar energy into useful clean utility electricity.

200 Amp DC System

Argus and Alpha Energy combined their expertise to provide a DC Power plant with fully integrated PV inputs for off-grid telecommunications grade power applications. The 200 Amp

DC System includes an Apollo T80 MPPT Charge Controller, a

Cordex™ controller and 3.6kW of Cordex rectifiers designed for

120/240Vac input, one battery string with 100AH of energy storage (3.8kWh at 80% DOD) and load breakers. The system will accept up to 4kW of PV input power on the single charge controller. With 120Vac input, the rectifier bank can be powered by a small, energy efficient, generator with no loss of charging capability. The DC Power Plant is ideal for telecommunications providers, security, military and pipeline companies who require secure DC Power in mission critical applications.

The DC Power Plant is highly configurable with powering options.

This means that it is easy to custom-configure an Alpha/Argus

Hybrid Power Plant to include inverter(s), DC converters, breakers, alarms, batteries and solar controllers.

Other features include ease of service and troubleshooting.

Cordex rectifiers, controllers and other system features can be accessed by way of a robust computer interface, which can be used locally or remotely. It also means that all Cordex rectifiers can be hot-swapped if there are units to replace. And rectifiers and inverters can be added if load requirements increase. This means lower risk of loss of load.

Additional features of this platform include:

>

Extensive alarm and relay programming capability

through dry contacts.

>

Scalability, rectifiers and inverters can be configured to

meet virtually any load/recharge requirements.

>

Systems can be designed at the factory for simple

plug-and-play expansion.

Grassy Mountain Case Study

Hybrid Solar Electric System

>

The 13.86kW Hybrid System was installed in Southwestern Colorado

>

Built to improve emergency communications

>

Provides 18.25MWh annually

Grassy Mtn. solar installation

This electrical system was built and installed for a county application in Southwestern Colorado as part of a project to improve emergency communications in the area. The site is located 9700' in elevation up a narrow and steep ATV path. An

800mZ repeater radio is the major load on-site with additional DC and AC power provided for local emergency service – fire, rescue and police - communication.

The combined load of all the communications systems is just over

50kWh 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 at the Grassy Mountain site. A 13.86kW PV array is the prime source of energy and it is backed up by a 20kW diesel generator.

The heart of the system is the Argus 400 Amp Hybrid Power

Plant which integrates input from the solar chargers and the AC powered rectifiers into the DC bus. The PV array is divided into four sub arrays each feeding an Apollo T80 MPPT charge controllers – these are connected together in a master-slave network which allows them to share common settings. The slaves communicate energy harvest information to the master.

The solar system on this site is not intended to meet 100% of the power requirements, it was designed to meet 86% with the remainder of the power coming from the 20kW diesel generator which is on site. The 240Vac output of the generator is converted into 48Vdc by a bank of Argus Cordex™ 3.8kW rectifiers. The hybrid nature of this system – PV assisted by a generator – maximizes battery life and minimizes the risk of loss of load.

The Cordex controller monitors battery state of charge and automatically starts the generator and energizes it’s rectifiers to begin a charge cycle when the batteries are approximately 50% discharged Once the rectifiers have completed the “bulk” cycle of charge – the part which most effectively uses the diesel being burned – they drop out, the controller stops the generator and the system lets the PV array complete the charge cycle.

One of the most unique characteristics of the Argus Alpha

Energy Hybrid Power Plant is the powerful command and communications capabilities of the Cordex Controller. At the

Grassy Mountain installation, Alpha Energy barely challenged the controller by establishing custom generator start parameters and then adding two different setting for controlling a ventilation fan.

All the custom programming for the controller as well as its extensive monitoring and alarm features are accessible on site with a laptop computer or remotely if a web connection is available. The multi-channel data acquisition capabilities of the controller allow independent monitoring of several currents such as; rectifier, load and solar input. Field proven algorithms process the data to produce accurate State of Charge calculations.
