Utah solar company accused of making false promises to customers

SALT LAKE CITY — The Department of Justice filed a complaint this week seeking an injunction against two Utah businesses' alleged false promises to customers that their purchases will give them substantial tax breaks.

R. Gregory Shepard and Neldon Johnson, both from Utah, are accused of using RaPower-3 LLC and International Automated System Inc. to sell solar technology to customers under a false premise that the equipment is groundbreaking.

"According to the complaint, the defendants' so-called technology is a sham," the Department of Justice said in a statement Monday.

Do Your Past Commercial Solar Projects Qualify For An Unused Tax Deduction?

Since 2006, IRS Section 179D has permitted qualifying buildings to receive tax deductions for energy efficiency. In general, the solar industry has been unaware of this tax break and, as a result, has not taken advantage of it.

Here's a look at the 179D tax deduction, some reasons why it has been overlooked and, most importantly, whether there is still time for you or your clients to retroactively claim Section 179D.

Solar Hot Water Collector Flow

Reader asks:

I’m curious about flow rate through solar water heating collectors and how that affects an SWH system’s efficiency. On one hand, it seems like a slower rate would allow more heat gain, since the water spends more time in the collector. But I also understand that efficiency is higher with water that is at a lower temperature. So then I assume that more water moving through the collector more quickly (even if it’s not getting as hot per cycle), is actually more efficient overall. Either way, how is a pump sized and flow rate optimized for maximum efficiency?
