New Energy Management System Saves Electricity and Money

Monday, August 2nd, 2010 | Green Power | No Comments

In May we started working with Empower in install an energy management system to help reduce our demand peaks. We have two major sources of power demand, air conditioning and our toner collection system. Our toner collection system has a 30hp motor that pulls air (and toner) from all of our workstations. The system is oversized and probably pulls more juice than it should. When we first installed it back in 1998, we figured we would be building twice as many toner cartridges withing a few years and would need the extra workstations. And while we are doing well, we have not grown as fast as we’d hoped. But I digress…

The energy management system or EDGE as empower calls it, monitors our total power usage and if we start pulling more than 40kw EDGE adjusts the temperature by a couple of degrees, while rotating HVAC unit one at a time at the normal temperature. Once the toner collection system goes off (and usage goes below 40KW), the AC units are then allowed to bring the temperature back down.

By reducing our peaks, we can reduce our overall power rate. Our previous high peaks were around 70kw. We’re hoping the new system will have our peaks around 40kw. In addition we seem to be using less power as well.

Empower recently used us a case study. Read more about our energy management system.


Solar Array Working Great!

Thursday, March 11th, 2010 | Green Power | No Comments

February was our first full month of solar power. As you can see we produced about 1,600kwh which is right on track with predictions. In the summer we should produce twice that. Our typical sunny day is producing 100KWH, but as you can see there are days where the array produces almost nothing. Maybe drought is good?

We’ve already avoided putting 1,822kg of CO2 into the atmosphere. That’s pretty cool.


And the survey says…

Friday, January 29th, 2010 | Green Power, Toner Cartridge Recycling | 3 Comments

We recently polled our customers on a couple of questions and the results are below. Note only about 2.8% of all emails sent to customers resulted in a completed survey. I’m not surprised, we’re all bombarded with unnecessary email and completing a survey isn’t exactly a top priority. Still even if only a few people complete the survey, it’s helpful to keep a tab on the pulse of our customers. We had 37 Brother P-Touch printers to give away for people that filled out the survey, and 450 people filled out the survey. Sorry we didn’t have a printer for everyone, for those of you that didn’t get one – better luck next time! On to the survey…

UPS vs. FedEx – We’ve just switched to FedEx from UPS and while half of our customers seem indifferent between the two services, those that did have a preference prefered FedEx. I guess we made the right move.

Recycling with “the box” – this one surprised me. To date, we’ve had very little participation with recycling with the box. We’ve tried fliers with each “box”, but not much success. We recycle so many common items, but most people hopefully are recycling locally. Yet 61% plan to recycle with the box. Hopefully the survey also worked as a reminder that we offer this service and will recycle more and more with the box. Check out our box recycle flier and see all that can be recycled with “the box”.

Buying from environmentally conscious green companies – The survey we split 50/50 between those that prefer to buy green and those that buy based upon superior product and service. Luckily with Advantage, you don’t have to compromise. We are green and we provide the best products and service!

That’s it for our survey. When we email our customers we really try to make sure we have something of value or an offer of value, because we know you are inundated with unwanted email. Thanks for being one of our valued customers!

Solar Project – Day 7

Tuesday, January 26th, 2010 | Green Power | 2 Comments

It’s been a week and we are now producing solar power, real green power delivered free from the sun! The array was installed in one day. It took another 2-3 days for the electricians to mount the inverters and run the conduit from the array to the inverters to our panel. Yesterday was sunny, so it was a good day to crank up the inverters and see what we were producing. We could have started it sooner, but it was rainy on Friday and the engineers from Empower didn’t want to launch on a cloudy day because there was still more testing to go and they wanted to see the array perform at full power. We’re producing 11KW of power right now at 11:20. That’s actual  power delivered into our electrical system after any loses from the inverter.We actually have three 6KW inverters. Here’s some actual data from each inverter…

The SMA WebBox collects data from the inverters on power generated and CO2 emissions avoided. You can checkout our power production at anytime from our SunnyPortal. Right now it doesn’t show much power generated, but it will. The system isn’t real time and only gets updated every so often. Still it’s nice to be able to monitor the power generated by the system.

At this point there really isn’t much to do with the system. PV systems such as this are relatively maintenance free. Annual maintenance includes pressure washing the panels and the roof underneath the panels, as the Solyndra modules rely on the reflective surface of the white roof for 20% of their power generation. I’ll  update in the future on the system performance promised vs. delivered. -Marvin

Solar Panel Project – Day 2

Thursday, January 21st, 2010 | Green Power | 5 Comments

Day 1 of the solar panel project was really satisfying as we were able to install all of the solar panels in one day. At the end of the day we could see what we’d accomplished. Day 2 consisted of testing each of the 9 strings to make sure the were functioning properly. The plan was to get all of the strings jumpered and connected to the splicer box on the roof, but we ran out of cabling so that will have to be finished on Friday.

While we were on the roof, the electrician ran conduit from the roof penetration to the inverters (indoors). 3 SMA SunnyBoy inverters will do the job, but they take up way more wall space than I’d hoped. I have no idea where we will mount the inverters for future arrays. We went with three inverters to save money over buying one large inverter, but there is a space penalty.

Day 3 is a bit of a wash, as it’s raining, so nothing will happen on the roof. The electricians will be able connect the inverters to our panel. This is how the power gets into our system. We also wired the sunny boy webbox to the inverters which will enable us to monitor real time power production and see exactly how much power is generated by the system via a web browser.

Day 4 – assuming it’s sunny, we should be able to run the power from the splicer box to the inverters and crank it up. That’s the plan.

Advantage Laser Solar Panel Project

Wednesday, January 20th, 2010 | Green Power | 6 Comments

Day 1 of the solar panel project got off to a bad start. The crane started setting up at 9:00 and was ready to go, but we had no panels. The truck was already a day late and communication with the trucking company was terrible. First the panels were supposed to be there Monday morning, then Monday evening, then Tuesday morning at 7:00 sharp, then at 9:00 they were an hour out, finally the panels arrived at 2:00pm Tuesday. Meanwhile we had 10 people standing around with little to do.

Once the panels arrived, we got to work with the crane. We had 8 pallets of panels and two more pallets of support legs and other misc hardware. The nice thing about the Solyndra panels is they are so fast to install. Once we got trained on the assembly, we were able to have all 125 panels installed by 6:30 that evening. Yes, we did finish in the dark, but it felt good to get the panels installed.

Check out more photo’s of the solar array.

Advantage Laser Installs 21.8KW Solyndra Solar Array

Monday, January 11th, 2010 | Green Power | 7 Comments

Next week we begin installation of rooftop solar array on our MICR toner cartridge manufacturing facility in Atlanta, Georgia. The solar project has been broken into three arrays. We will start by installing Array #1 – a 21.8KW array that will produce 29,654 KW hours per year. This will only provide about 23% of the power we currently use. Once Arrays #2 and #3 are built the complete system will provide 70% of our power usage. Our goal will be to become power neutral meaning we produce 100% of the power we need. So after all 3 arrays are installed, we will have to decrease our power usage by 30% via increased efficiency e.g. LED lighting project (more on that later).
It Makes Environmental and Business Sense
The environmental benefits of solar power are obvious, the challenge is to operate as green as possible and still remain a viable business. I looked at solar a couple of years ago, but it was difficult to make the numbers work. The federal government was giving a 30% tax credit and the state (Georgia) had no incentive whatsoever. Several months ago Mark Bell with Empower contacted us about solar. He got us up to date on solar power legislation and incentives. Solar (green) power was included in the economic stimulus and recovery act of 2009. Now the federal government will pay the 30% as a grant up front and the state of Georgia will give an additional 35% tax credit towards a commercial solar installation. This made all the difference. The federal grant, means we don’t have to borrow as much money. The state also has a grant, but it is limited to $2.5 million and applications flooded the GEFA office. The rebate program was closed after just one day. So we’re going the tax credit route, which creates a challenge in itself. Sometimes I think the tax aspects of a solar array are much more complex than the technical ones. After calls to two accountants, the state and Empower, we determined the array would pay for itself in about five and a half years. Not bad, after that we’ll have an array with a 25 year life expectancy with free green power.
Solar Panels Made in the USA

Much of the solar PV (PhotoVoltaic) is dominated by China these days. We prefer to buy products made here in the USA when we can. Lucky for us, we have a white roof. Why should this matter? This allowed us to install a new innovative solar panel from Solyndra (made in Silicon Valley CA). Traditional PV uses a solid panel that is angled to the sun to maximize efficiency. But angled panel makes a great sail and therefore it requires a physical attachment and penetration through the roofing system or a heavy ballasting system.

Solyndra has a revolutionary solar panel that uses a series of tubes with space between them so that the wind passes right through them. The tubes on the Solyndra panel absorb the sunlight that is reflected off the white roof as well. The result is an array that can be installed in a fraction of the time and maximizes efficiency per square foot. The Solyndra panel costs about twice as much as a traditional panel, but the savings in installation time and mounting brackets make them come out about even. We are one of the first Solyndra customers in the Southeast for a technology that may revolutionize solar installations on many flat-roofed buildings.
Below is our rooftop layout of all 3 arrays. Array #1, on the far right, will be the first. Installation of all three was too much of a financial burden. Our goal is to install an array each year for the next 3 years.
Once Arrays 2 & 3 are complete, our system power will be a total of 65.9 KW producing 85,865 KW hours a year.

Selling Green Power vs. Decreasing Peak Load
As we harvest energy from the sun there are several ways to take advantage of it. One is to use the power ourselves with net metering. With net metering our meter “run backwards” when we’re producing more energy than we’re using. Otherwise it just slows down our meter. An advantage of net metering is we can use the solar array to decrease our peak load. Commercial customers are charged per KWH, but GA Power has incentives to business to smooth out their power usages by charging more, the higher your peak load. Each month a commercial business peak load rate is determined by the highest half hour power usage in the previous 11 months. The business about calculating peak load appears to be intentionally designed to be confusing. Empower has been working with us to see if they can decrease our peak load, and thus lower our overall price we pay per KWH.
Another option we have is to sell our “green” power to GA power through their Green energy buyback program. In this program, we take 100% of our green power and sell it to GA Power for $0.18 per KWH (about 4-5 cents per KWH than we pay for solar power). Right now GA Power’s green energy buyback is closed to new energy providers. The program is capped 1.5 Megawatts per year, which isn’t that much.
Increasing Efficiency
We are investigating a LED lighting project that would replace all of our existing florescent lights with new LED fixtures. Initial estimates indicate we would save about 15KW with the LED project. Empower is also consulting with us on the LED lighting project as well.
We are also replacing the largest two of our four HVAC units with new Trane High Efficiency units. We’ve also added rooftop motion detection and surveillance cameras. This will double to protect our solar array as well as our HVAC units from copper theft.

Installing a solar array has some exciting possibilities, but before you take the plunge, do the research. There is a lot to learn, especially about the tax code and what you can deduct and what you can’t. But in the end, if you have a long term perspective, investing in a solar array makes sense. Imagine the energy savings and decrease in air pollution that would be possible if every business with a roof filled them with solar panels.
I’ll be posting pictures of the array installation as I can. -Marvin Masson
