U.S. Army Awards Energy Saving Contracts Worth $61 Million

Solar News - Tue, 21/02/2012 - 13:19
Three energy saving contracts worth $61 million have been awarded to Siemens Government Technologies and Johnson Controls Inc. by the U.S. Army. All three projects will save the Army 267 BTU's (British Thermal Units) yearly and over time provide the capacity to generate 8.2 megawatts of energy.

Last December the Army awarded Siemens Gov. Technologies The White Sands Missile Range Project worth $16.8 million and has 4.44 capacity megawatts of photovoltaic technology installed. Ten percent of the installation's energy will be provided by this project and the annual savings will be $930,00. When finished this will be the Army's largest renewable energy project, a title held now by the 2 megawatt solar capacity project at Fort Carson Colorado.

The Army awarded Johnson Controls Inc a $16 million for the Fort Bliss, Texas project that is projected to save $42 million in energy costs over a 25 year period. The agreement will allow the Army to purchase 5,500 solar panels without having to own and maintain them. This project is expected to generate 2.2 million kilowatt hours of electricity annually.

Included in that project is technology that will continuously monitor, control and manage the energy consumption of 120 buildings.

Johnson Controls Inc will benefit to the tune of $34 million with another Army project based in Puerto Rico - Fort Buchanan. In addition to Fort Buchanan the Army will also solar up 11 Army Reserve Centers on the island. Over time this 16 year contract will provide The Army with a savings of $65 million dollars.

These projects will help the Army meets it's energy saving goal of producing 25% of it's electricity using renewable energy sources by 2025.

The Army has an agreement with these tech companies called an Energy Savings Performance Contract which lasts 25 years. This agreement allows the Army to be hands off regarding the operation and maintenance of the equipment and the companies benefit by recouping their investment through an agreed-upon percentage of the guaranteed cost savings.

Intel Considering Solar Powered Computer CPU Chip

Solar News - Mon, 20/02/2012 - 12:56
Last year Intel experimented with a solar powered processor that operated when light hit the CPU and stopped when the light was blocked. The light source was a reading lamp that emitted just enough light to power the chip.

Known as the near-threshold voltage (NTV) CPU and code-named "Claremont." The postage stamp sized chip's voltage ranges from 280 millivolts when the system is running at 3MHz to 1.2 volts when running at approximately 1Ghz.

Intel's chief technology officer Justin Rattner said "It's allowing us to make Intel's product more [power efficient] across the compute continuum" while reaching appropriate performance levels."

The new chip could keep laptops running at the lowest voltage levels when not in use without killing the battery. The design of the new chip is creating a lot of interest and will be featured at the International Solid State Circuits Conference in San Francisco through February 23rd.

Rattner explained the NTV chip is generating energy gains 5 to 10 times higher and they want to expand the use of this improved technology to computer graphics and memory.

Ideas on How to Save When Buying Solar Panels

Solar News - Tue, 14/02/2012 - 12:26
Save Big On Solar Panels Cost
By William Benard

Have you been thinking about setting up solar panels for your home, but gotten discouraged because the solar panels cost happens to be too large? With the help of proper design and system sizing methods the cost of solar power systems will be considerably lowered. Additionally you can easily save in the vicinity of 40% on the cost of a solar power system by getting a kit and installing it yourself.

To start with you must decide to go with a grid-tied system or an off-grid system. One of the leading advantages of a grid-tied system is that you never have to purchase batteries. The batteries are generally expensive not to mention they need routine maintenance and they have to be replaced every so often. You might also decide to set up a smaller sized, less pricey system in order to decrease your solar panels cost. Given that you're still on the grid the small-scale system only needs to provide only a portion of the electrical power. On the downside grid-tied systems provide no electrical energy when the power grid is down.

The second step to planning your solar power system is to evaluate rebate options and acquire permits. Your area power utility company has rules you'll want to comply with when hooking up the finished system to the grid, and building codes may likewise apply. In conjunction with federal incentives, states (and certain cities) offer refunds that can help with the price of the system. Finding out the rules in your region before you start will certainly save you frustration later on. Check out the Database of State Incentives for Renewable Energy (DSIRE) for information and facts dealing with rebates in your state. It's also a good idea to learn about net metering guidelines where you live, which include how much money you can get paid for generating excess power.

Choosing the size of your system is the next step. With a grid-tied system, size is less significant, due to the fact the grid supplies electric power whenever your photovoltaic (PV) system falls short. Solar power systems no more than a couple hundred watts have proven to be practical, however you can also set up solar panels that will be able to generate enough electrical energy for all your needs. Review the amount of electrical power you use now, then calculate what you will likely be able to save as a result of implementing conservation and efficiency measures throughout your house. This approach is going to provide you with a better understanding of how big a system you'll need to build. You may build any size system you want, even so it may not pay to put in a bigger one. A scaled-down system will hold your solar panels cost down.

Determining ways to use less electrical energy in your house is almost always more cost effective compared with setting up a bigger PV array. The average amount of electrical power used monthly in a standard United States household is around 1,000 kilowatt-hours (kWh). It is actually feasible to get this lowered to approximately 500 kWh by investing in the region of $1,000 for energy efficient lights, power strips with switches, an efficient fridge along with a few other strategies. Compare that with a solar power system which generates 250 kWh per month but will cost you $6,000 - it's obvious where the best pay back is. Perform the efficiency measures 1st, then design the solar panel system.

Once you have a better understanding of the quantity of solar power that you need to produce each month you will be able to determine what the solar panels cost is likely to be. For instance, in the event that you conclude that you want a PV system that makes approximately 250 kWh monthly that is 3,000 kWh a year. These stats will be utilized to compute just what size PV system is actually ideal for you specific location. You should start with a service such as the National Renewable Energy Laboratory's PV watts calculator to compute this size of a solar energy system that would deliver 3,000 kWh a year in your region.

The following step is determining how to appropriately position the solar panel array. If possible, the solar PV panels for your home are going to face south, and also be tilted at an angle about equivalent to the local latitude. They will also remain in full sunshine with no shading from about three hours before solar noon (the time when this sun is right in the middle of its course across the sky) to three hours after solar noon. Performance won't suffer much if you can't get the panels aimed directly south or angled perfectly, on the other hand even a small amount of shading can have a serious negative effect.

A fairly new feature that is recommended for grid-tied systems is implementing micro-inverters. Micro-inverters provide a benefit in partial-shading scenarios since every single PV panel has got an inverter that delivers maximum power point tracking to obtain the most electric power possible out of that particular solar PV panel, whether it is slightly shaded or in complete sun. Regarding typical string inverter systems, partial shade can potentially cause the voltage of a string of solar PV panels to drop to the level where the inverter shuts down and electric power output drops to zero - a big effect, indeed. If you have serious shade issues which you cannot fix, a PV solar panel system is most likely not a beneficial choice for your situation.

A solar site survey should tell you about any type of potential shading issues for any season. You may do the solar site survey in a couple of ways. One way is a process in which you work with a "sun chart" for your location together with a basic sighting of objects that may cause shadows - this approach can potentially end up being an interesting family event to help teach everyone about the course of the sun throughout the year. Another simple method is actually to model the solar PV panel array as well as possible shading objects in the free Google SketchUp drawing tool. SketchUp has a feature that will demonstrate shading patterns for any time period of day and year.

If you have the space chances are you may choose to go with a ground mounted system due to the fact it will make the solar panel installation quite a bit easier (and less frightening), and you will not be required to remove the panels in the event that the roof ever needs to be replaced. PV solar panels are going to most likely last 30 years, so choosing where and just how the solar panels will be mounted is very important. Designing a system that provides you with the option to start small and grow the system when time and finances permit can without a doubt make the initial solar panels cost more economical.

Boulder City Tapping Into Solar Power for Revenue

Solar News - Thu, 09/02/2012 - 12:59
The small Nevada town of Boulder City can thanks it's representatives for making good deals with solar power providers. City Manager Vicki Mayes says that in the future the city will generate $12 million a year in lease payments alone. Projects in planning stage now will produce revenue for Boulder City for years to come.

The city made sure the solar companies paid large upfront payments during the two to four year construction period. Through the life of the lease contracts the city will collect upwards of $480 million dollars which will generate needed revenue and help pay off debts.

Boulder City attracts the attention of solar companies because of it's constantly sunny climate (300 sunny days a year) and already available transmission lines.

The leases between Boulder City and the solar providers range in the 40 to 50 year range and will also provide property tax revenue.

A couple of the photovoltaic projects that have begun operation are already among the largest in the nation.

City council members are congratulating each other on their ahead-of-the-pack pro-solar decisions that will benefit residents for years to come.

What to Look for When Purchasing a Solar Inverter

Solar News - Mon, 30/01/2012 - 12:31
Solar Inverters - What to Look For When Buying an Inverter For Your Solar Power Project
By Greg Murry

It does not matter if your solar project is a DIY or off the shelf system, you will need an inverter to convert your power from DC to AC current. Inverters can be quite costly and so are a major consideration in your project. If your solar system is to provide power in a remote location such as a small farm or "back woods house", then you need to buy one that suites your needs. Begin by looking at the type of appliances and what loads you will have. Check the wattage, continuous and surge power requirements. You may find that a cheaper modified square wave inverter would do the job rather than the more expensive sine wave units. While it is possible to buy cheaper inverters, most people would agree that you get what you pay for, so here are a few hints when comparing units.

Safety: Many people place this as a last consideration, however, you must consider the safety aspect of the unit you intend to purchase. You need to know if the inverter meet all relevant safety and RFI standards of the country you live in. When fitted it should be connected via a safety cutout.

Wattage: Check the wattage, note that bigger units may not suite your needs. Look for inverters that provide information on continuous, intermittent (30 minute), and surge rating. Large inverters will be less efficient on very small loads than smaller inverters. Lightweight inverters with no transformer may not have the ability to handle surges. Look for units that suite your power requirements rather than its capacity.

Wave Type: The best inverter produces power as a true sine wave. Many cheaper inverters are likely to be what is called, "modified" square or sine wave inverters. While square wave units are cheaper, some appliances including fans, washing machines, stereos, digital clocks and timers, do not work as well and will run slower, hotter or noisier than on a sine wave unit.

Standby : Does the inverter have a standby or auto-start mode. This can cut its power draw significantly, without this feature, the unit can draw quite a lot of power from your batteries. Also check how much power the inverter uses when it is waiting to detect a small load.

Input Handling: When your solar panel system is operating and charging batteries, output can vary from as low as perhaps 10 volts up to 15.5 volts. A good inverter should operate with input voltages between 10 to 16 Volts.

Distortion : Make sure the inverter hold its output frequency to within 0.01% and has less than 4% harmonic distortion. You should also check that the inverter can maintain its output AC voltage to within 3-5% off the desired voltage.

Efficiency : Ask how efficient the inverter is, does it give its specifications in 'peak efficiency' or does it show you how it performs with small 50-100 Watt loads up to its rated power.

Diagnostics: What on-board diagnostics does the unit have. Can it identify, low and high battery, overload and over temperature.

Warranty: What kind of warranty does the unit have and what are the service agreements. Countries such as Australia and the USA are big places, and the service center should be as local as possible. Look for a long warranty period and local service.
