To sell truly clean, green solar power that increases the energy savings, longevity, and effectiveness of solar and other home equipment, proactive dealers are now adding a power conditioning and protection component to typical solar panels, racking, and inverters.
By providing a more complete electrical solution that handles household dirty power such as surges, spikes, interference and harmonic distortion to increase overall electrical efficiency in the home, solar dealers are distinguishing themselves from the competition and adding an additional profit center.
Since the U.S. grid uses alternating current (AC) power, the direct current (DC) created by a solar inverter is converted into AC power. This makes it compatible with the grid and usable for home electronics and appliances such as TVs, computers, and vacuums.
Yet home solar inverters must accommodate a wide range of loads - everything from a single low-wattage bulb to a power tool with a big start up surge. While the battery voltage of a solar system can vary by up to 35%, depending on charge and activity, it must narrowly regulate its output.
In the solar inverter DC to AC conversion process, some power is lost as heat, with more heat a sign of low-efficiency conversion. The process often creates nano-surges and spikes that can damage sensitive electronics, as well as higher than desired electro-magnetic fields (EMFs) and levels of harmonic distortion (THD). Electricity with high levels of EMF and THD is not clean electricity.
Since AC power travels in a wave, disrupting the wave can rob it of its power and introduce interference. Other equipment in the home from vacuums and hair dryers to refrigerators and dishwashers can also disrupt AC current, creating dirty electricity that degrades the ability of solar units or other equipment to function.
Extra Energy Savings
For instance, the Power Perfect Box from Satic USA, a UL listed American manufacturer of energy saving products, is a line conditioning, power quality and phase quality increasing device that reduces the amps needed to run home electrical appliances. Installed at the breaker panel, it has been proven by third party testing to reduce EMFs by up to 99% and THD up to 98% depending on the system. Reducing EMFs and THD to this degree can significantly improve the DC to AC conversion rate and reduce the energy lost as heat.
"The Power Perfect Box conditions dirty power so solar and home equipment run better, cooler, with lower energy consumption and greater longevity," says Mark Johnson, owner of 76 Solar, a Phoenix, AZ-based solar dealer that operates in several states. "Nationally, about 74% of power is usable in typical home electrical lines. This approach takes usable power up to 95%."
The device uses proprietary harmonic-resistant power quality and phase quality correction modules that correct the electrical phase, causing the waves to move in synergy with each other. This helps homeowners optimize usable power in home electrical lines up to 95%, and increases electrical panel capacity by lowering amperage and temperature. The result saves energy and further lowers homeowners' utility bills.
"In our experience, the power conditioning device saves typical homeowners about 10 to 20% in more efficient energy use alone," says Johnson.
David Brady, CEO of Erus Energy an Arizona-based solar dealer servicing six states says, "I have noticed savings on my electrical costs after the Power Perfect Box was installed in my own home."
Normally, electronics dissipate excess power from the electric panel as heat, which can shorten their effective lifespan. The power conditioning device turns this wasted heat energy into real working power, which prolongs the life of electronics.
"By installing the power conditioning device at the main electric panel, it protects not only solar equipment but also the home's electronics and appliances, even those that are traditionally hard to protect like the dishwasher," says Johnson. "It reduces electrical wear and tear on everything and extends equipment life."
"Everything from the solar inverter to the TV, refrigerator, and air conditioner will run better, cooler, more efficiently, and with greater longevity when homeowners have a cleaner power line," adds Brady. "We provide it to our customers as part of their solar solution."
In addition to providing cleaner power, the device can also improve audio-visual performance in TVs, stereos and other equipment. Homeowners that experience an improvement in the performance of their electronics are more likely to act as referrals to friends and family.
"Many homeowners have noticed the effects of dirty electricity in their home electronics, such as white lines appearing on the TV when someone vacuums, or a pop or static in stereo speakers when the refrigerator kicks on," says Brady. "Since the device conditions home power lines, it resolves those issues so TV and stereo quality is noticeably better, which they're happy to tell their friends about."
"We have found that including the device in our total solar package helps us with the sale and referrals," adds Johnson. "We get more referrals because when neighbors talk, they want the power conditioner with the solar system, not solar by itself."
Sell to Those who Can't "Go Solar"
For instance, if people that can't buy solar due to having the wrong type of roof, excessive tree shading, condo association rules, or a lack of sufficient credit, many still express interest in purchasing the Power Perfect Box.
Johnson says, "The power conditioning devices go beyond solar, and are really more of a total, home-wide electrical solution. They could make other forms of alternative energy, such as wind, even more effective as well."
Enhancing Privacy, Reducing EMF
Smart meters also emit EMF radiation to communicate with utility companies along smart meter networks. Some power conditioning equipment can also reduce EMF exposure significantly, which is a particular concern among pregnant women, children, and the elderly.
"With privacy concerns about smart meters and EMF exposure a rising concern of homeowners, power conditioning equipment like the Power Perfect Box will be an easy, profitable way for solar dealers to address those concerns while supporting solar energy savings," says Johnson.
"If homeowners are interested in reducing EMFs, this device is a perfect complement to those goals, even if rooftop solar isn't possible for them," concludes Brady.
In addition to the wire-in power conditioning devices installed at the electrical panel by a licensed electrician, easy-to-use, plug-in models are available for any home electrical outlet. Full-spectrum, energy-saving light bulbs for home use are also available as part of an integrated green solution.
