VIDEO: Solar Panels Explained at MD Solar & Wind Expo
Michelle Waldgeir of Astrum Solar breaks down how solar panels work.
The idea behind using solar panels to power your home's electricity may seem simple on the surface—install the panels to your roof and let the sun do the rest.
But making the multi-thousand dollar commitment to your home (and the environment) usually yields a host of questions, says Michelle Waldegeir, marketing vice president for Howard County-based Astrum Solar.
What happens when one panel goes out? How many will I need for my roof? How exactly do the panels work? How are they attached to my roof? What if part of my roof is shaded?
Patch asked Waldgeir, who represents one of the largest vendors of solar panels on the East Coast, to break down the process of solar panels and what possible consumers should expect. (See video)
Astrum Solar, as well as 12 over certified vendors will be on hand throughout the weekend at the third annual Maryland Solar & Wind Expo at the Maryland State Fairgrounds in Timonium.

"The people who come here are the folks who are looking to making a change. ... It's time to get off the gasoline, and electricity can be gathered from the sun," xpo director George Lopez said.
The vendors are also hosting seminarsthroughout the weekend to further explain costs associated with solar panels and to demonstrate how installation works.
The third annual event is noticeably less crowded by vendors than when it was first introduced in Maryland in 2009.
"Just like in every business you'll have the strong and you'll have the weak. One of the things that we decided right from the beginning was not to lower our standards," Lopez said. "To put it frankly, I kept a few people out. The folks that are here—and most of them have been here since the beginning—are thriving, they're hiring and they're putting people to work."

I hate to throw a wet blanket on this story, but from my research on the internet I find that the payback time (the time it takes to recoup the money you pay for these systems) is generally around 25-30 years. The projected life of these systems is approximately 15 years. This means, of course, that you will NEVER really gain back the money you pay for these systems over the course of their lifetimes. Sorry, but like the so-called "green" electric cars, buying these systems is a sucker's bet that will NEVER pay off in the end.

I am not sure how long ago you did your research on the internet or where the information you are citing is coming from, but the average payback for residential solar in Baltimore county is ~5 years and it can be immediate if a homeowner chooses a no-money down solar lease. Not only do you really gain the money back in a reasonable time frame, the lifetime of these systems is much longer. Both the solar panel and microinverter manufacturers shown here stand behind that and warranty their products for 25 years. Many Maryland residents folks who bought solar in 2009 have already achieved payback.
