New Report: Rooftop Solar Provides Benefits to Michigan’s Electric Grid

LANSING – Utility customers with rooftop solar systems, known as solar distributed generation (DG), are providing economic support to Michigan’s electric grid and should not be overcharged to support it. That is among the findings of an analysis by the Institute for Energy Innovation, “Solar Energy in Michigan: The Economic Impact of Distributed Generation (DG) on Non-Solar Customers.

The report was completed in advance of a study to be undertaken by the Michigan Public Service Commission (MPSC) required under Michigan’s new Clean and Renewable Energy and Energy Waste Reduction Act.

Solar energy jobs in Michigan jump 48% in 2016

LANSING – The Michigan Energy Innovation Business Council, a trade association for renewable energy companies, announced Monday that a new report from the Solar Foundation found that jobs in Michigan’s solar industry jumped by an impressive 48 percent from 2015 to 2016.

During that time, Michigan solar companies added more than 1,300 jobs, for a total Michigan solar workforce of 4,118.

This positions Michigan second in the Midwest both in terms of growth rate and number of individuals employed in the solar industry, Nationally, Michigan now ranks 15th in the number of solar jobs, up three spots since 2015. (Ohio leads the Great Lakes are with 5,831 solar jobs, and employment grew there 21 percent in 2016. Indiana had the fastest growth rate, 72 percent, but has the smallest number of solar jobs in the region, 2,700.)

Nationally, the Solar Jobs Census 2016 reported that solar employment has nearly tripled since 2010 and was up 25 percent over 2015, with the industry adding more than 21,000 jobs in 2015 for a total of more than 260,000 solar workers nationally. This is the fourth consecutive year of more than 20 percent national solar job growth. Last year, one out of every 50 jobs created in the United States was in the solar industry. Notably, solar now employs twice as many people as the entire U.S. coal industry, and the same number as work in natural gas.

The Michigan EIBC represents companies across the full range of the advanced energy sector, including advanced materials, biomass and biofuels, energy efficiency, energy storage, lighting, smart grid, solar, transportation, and wind.

Plug In For Renewable Energy

HOUGHTON — Support for solar energy is vast. According to a 2015 Gallup poll, 79 percent of Americans want the US to put more emphasis on developing solar power. Most of the same people, unfortunately, can’t afford to install solar energy systems in their homes. Even after federal tax credits, installing solar panels to cover all of a family’s electricity needs can cost tens of thousands of dollars. For others, a home solar system isn’t a consideration because they rent, or move frequently.

But Michigan Technological University’s Joshua Pearce says he knows the solution: plug and play solar.

“Plug and play systems are affordable, easy to install, and portable,” said Pearce, an associate professor of materials science and engineering and of electrical and computer engineering. “The average American consumer can buy and install them with no training.”

In a study funded by the Conway Fellowship and published in Renewable Energy (DOI: 10.1016/j.renene.2016.11.034), Pearce and researchers Aishwarya Mundada and Emily Prehoda estimate that plug and play solar could provide 57 gigawatts of renewable energy – enough to power the cities of New York and Detroit – with potentially $14.3 to $71.7 billion in sales for retailers and $13 billion a year in cost savings for energy users.

Sounds great, right? Well, there’s one problem: in many parts of the United States, electrical regulations don’t allow consumers to plug and play.

Small investment, big return

Plug and play solar panels connect to an ordinary electrical outlet. You’re still on the grid, but you’ve become a “prosumer” — a consumer of energy who also produces it. The panels range in wattage and are relatively affordable, with some costing just a couple of hundred dollars. A prosumer can start small, with just one panel, and slowly build up over time to a system that produces 1 kilowatt of energy, the equivalent of powering 10 100-watt light bulbs.

The panels are also portable. So, for example, if a college student buys one 250-watt plug and play panel each year for four years, reaching 1 kilowatt of energy by senior year, that student can unplug the four panels when she graduates and take them to her next destination.

Pearce estimated that plug and play systems could generate more than four times the amount of electricity generated from all of U.S. solar last year.

“The vast majority of this energy never leaves the home,” Pearce said. “It’s the equivalent of handling a hair dryer load. We’re talking about almost nothing on the electrical grid – but that nothing adds up. It’s an appliance with a high rate of return.”

Safe, simple — and largely prohibited

In the U.S., a patchwork of local jurisdictions and regulations make it difficult to figure out if and where plug and play panels are allowed.

“You can buy the panels, but you might not be able to plug them in, depending on your utility,” Pearce said.

In a paper published earlier this year in Solar Energy (DOI: 10.1016/j.solener.2016.06.002), Pearce, Mundada and researcher Yuenyong Nilsiam reviewed all regulations in the U.S. that would apply to plug and play systems. They found no safety or technical issues with the equipment on the market.

“This is an area where less regulation could really help renewable energy,” Pearce said. “We know that the technology is safe, and the law should reflect that.”

The risk, according to Pearce, is putting too much current on one circuit, so he recommends that homeowners keep their plug and play systems to a kilowatt or less. Simple precautions make this easy — if a panel is plugged into an outdoor outlet, for example, safety plugs on all other outdoor outlets on that circuit can prevent overload.

While some jurisdictions have recognized that there are no major safety or technical issues with plug and play panels, paperwork holds up the process. Potential prosumers often have to fill out complicated forms to fulfill utility requirements, and the paperwork and associated fees vary by utility. To simplify the process, Pearce and colleagues automated it, by writing open-source computer code that fills out every possible technical requirement. Utilities can easily use the free code on their websites.

“Some utilities have embraced plug and play, and some have ignored it because they think it’s a pittance,” Pearce says. “But plug and play solar is something that can help most Americans.”

Stopping urban flooding and pollution: experts talk stormwater management at LTU

SOUTHFIELD – What does Michigan do with the extra water that comes from heavy rainfall events that now seem to flood the area every few years?

Nearly 300 government officials, engineers and infrastructure experts gathered Friday at Lawrence Technological University to continue the effort to figure that out.

The fourth annual Regional Stormwater Summit, presented by LTU, the Oakland County Water Resources Commissioner’s Office and the nonprofit group Pure Oakland Water, had no easy answers, but speakers at the event said green infrastructure will be a key part of the solution.

M2 TechCast: LTU’s Carpenter Explains How Green Infrastructure Can Clean Water Runoff Mother Nature’s Way

ROYAL OAK – Don Carpenter, water expert from Lawrence Technological University, discusses green water infrastructure and what it could mean for cities like Flint in this episode of M2 TechCast.

Green infrastructure is nature’s way of handling storm water runoff. If lakes, streams, and oceans do not realize we have developed the land adjacent to them, that’s the gold standard of storm water management, Carpenter said. Examples of green infrastructure include green roofs, green walls, rain gardens, and urban agriculture.

One of the barriers to entry is most engineers don’t have the design tools to deal with storm water runoff in a green way, he said.  Also, home owners need to get past the idea that they need green lush lawns. If they planted natural grasses and flowers, it would be much lower maintenance and much better for the environment, he said.
