Federal Modified Accelerated Cost-Recovery System (MACRS) + Bonus Depreciation (2008-2009)
Applicable Sectors: Commercial, Industrial
Authority 1: 26 USC § 168 Date Effective:1986 Authority 2: 26 USC § 48

Eligible Renewable/Other Technologies: Solar Water Heat, Solar Space Heat, Solar Thermal Electric, Solar Thermal Process Heat,
Photovoltaics, Solar Hybrid Lighting, Landfill Gas, Wind, Biomass, Renewable Transportation Fuels, Geothermal Electric, Fuel Cells,
Geothermal Heat Pumps, Municipal Solid Waste, CHP/Cogeneration, Direct Use Geothermal, Anaerobic Digestion, Microturbines

Under the federal Modified Accelerated Cost-Recovery System (MACRS), businesses may recover investments in certain property
through depreciation deductions. The MACRS establishes a set of class lives for various types of property, ranging from three to 50
years, over which the property may be depreciated. A number of renewable energy technologies are classified as five-year property
(26 USC § 168(e)(3)(B)(vi)) under the MACRS, which refers to 26 USC § 48(a)(3)(A), often known as the energy investment tax credit or
ITC to define eligible property. Such property currently includes: a variety of solar electric and solar thermal technologies
fuel cells and microturbines geothermal electric direct-use geothermal and geothermal heat pumps small wind (100 kW or less)
combined heat and power (CHP). The provision which defines ITC technologies as eligible also adds the general term "wind" as an
eligible technology, extending the five-year schedule to large wind facilities as well.

In addition, for certain other biomass property, the MACRS property class life is seven years. Eligible biomass property generally
includes assets used in the conversion of biomass to heat or to a solid, liquid or gaseous fuel, and to equipment and structures used
to receive, handle, collect and process biomass in a waterwall, combustion system, or refuse-derived fuel system to create hot water,
gas, steam and electricity.

The 5-year schedule for most types of solar, geothermal, and wind property has been in place since 1986. The federal Energy Policy
Act of 2005 (EPAct 2005) classified fuel cells, microturbines and solar hybrid lighting technologies as five-year property as well by
adding them to § 48(a)(3)(A). This section was further expanded in October 2008 by the addition of geothermal heat pumps,
combined heat and power, and small wind under the The Energy Improvement and Extension Act of 2008.

                            50% FIRST YEAR DEPRECIATION FOR 2009-10
The federal Economic Stimulus Act of 2008, enacted in February 2008, included a 50% bonus
depreciation (26 USC § 168(k)) provision for eligible renewable-energy systems acquired and placed
in service in 2008. This provision was extended (retroactively to the entire 2009 tax year) under the
same terms by The American Recovery and Reinvestment Act of 2009 enacted in February 2009. To
qualify for bonus depreciation, a project must satisfy these criteria:
the property must have a recovery period of 20 years or less under normal federal tax depreciation
• the original use of the property must commence with the taxpayer claiming the deduction;
• the property generally must have been acquired during 2008 or 2009; and
• the property must have been placed in service during 2008 or 2009 (in certain cases, in 2010).

If property meets these requirements, the owner is entitled to deduct 50% of the adjusted basis of the
property in 2008 and 2009. The remaining 50% of the adjusted basis of the property is depreciated
over the ordinary depreciation schedule. The bonus depreciation rules do not override the
depreciation limit applicable to projects qualifying for the federal business energy tax credit. Before
calculating depreciation for such a project, including any bonus depreciation, the adjusted basis of the
project must be reduced by one-half of the amount of the energy credit for which the project qualifies.

versions of those contained in tax code, which often contain additional caveats, restrictions, and
modifications. Those interested in this incentive should review the relevant sections of the code in
detail prior to making business decisions.

     Note: DC has said it will offer incentives for solar thermal systems. Under consideration is a $1.50 per Watt of a solar
     water heating system rated capacity. Exactly how this will be calculated remains open. If a thermal panel produces
     12,900 kWh of energy per day, over an 8 hour day output is 1613 Watts per hour and a possible incentive could be
     $2,420. Stay tuned.
                                       D.C. REBATE PROGRAM DESCRIPTION
In February 2009, the District Department of the Environment (DDOE) introduced the Renewable Energy Incentive Program (REIP),
a rebate for solar photovoltaic (PV) and wind energy systems. The REIP is funded through the Sustainable Energy Trust which is
supported by a public benefits charge on utility bills. By the end of 2009, DDOE plans to introduce incentives for additional
technologies, including solar water heating, solar space heating, geothermal, and methane/waste gas capture.

Most PEPCO customers within the District of Columbia are eligible for incentives under this program; however, the federal
government, the D.C. government, and public schools are specifically identified as ineligible. Systems must be at least 1 kW in order
to qualify and should be sized not to exceed on-site energy consumption as measured for the previous 12 months. There is no
maximum system size, although incentives are capped at $33,000 per site per fiscal year. The current incentives for solar and wind
energy systems are as follows:

$3/watt for first 3 kW installed capacity
$2/watt for next 7 kW installed capacity
$1/watt for next 10 kW installed capacity

Applicants must get a site assessment and conduct a prequalification application to get a reservation number. Once the
prequalification application is approved, the applicant must complete a final application. If funds run out for a given year, applicants
hold their place in line for one year with their reservation number and may receive funding the next year. The system must be
completed within six months of the award date. If the system is not completed, the applicant may get a six month extension. If the
system is not completed at the end of the extension, then the rebate must be returned to DDOE.

Projects must be located within the District of Columbia and applicants must be customers of Pepco. Projects receiving incentives
must be grid-connected and must follow the interconnection, operation, and metering guidelines set by Pepco and the DC Public
Service Commission. Large systems must have remote communication capabilities for monitoring of the performance meter.

System is predicted to generate 5006 kWh of electricity per year.

Net system cost with incentives = $8,165.94. (does not count effect of taxable grant)

Over 10 years with no maintenance costs, the cost of electricity from this investment in solar equals $0.163/kWh.
This is about the amount Maryland PEPCO customers now pay with all their charges. Electricity costs are likely to rise faster than
inflation in the coming years, so in the 10 year period, the solar electricity should be cheaper than Pepco rates from the first year

Over 20 years with cumulative solar electricity output at 85% of predicted year-one output (panels lose efficiency over time, are
guaranteed at 80%), the cost of electricity generated equals $0.096 per kWh.

Brokers will buy kWhs produced by PV system owners to sell a RECs market.
The kilowatt hours a homeowner’s PV system generates can be used by a
utility company that is required to have a certain amount of its power
generated with solar energy. Some believe that RECs will eventually replace
state incentive programs and that RECs will create incentives that will help
expand the solar market more rapidly (They have in California).

An issue is “RECs and Additionality.” Critics contend RECs let others who should
or could invest in renewable energy avoid such expense by “buying” the
output that other investors have made. The other side is that RECs are an
incentive for those with the means to invest in renewable energy systems when
they might not have without this additional income.

The Renewable Energy Credit (“REC”) Market
A RPS is a state regulatory regime, authorized by statute, which requires the
suppliers of electrical energy to customers within a state to provide a certain
percentage of such electrical energy through renewable energy (“RPS
Requirements”). To meet these requirements suppliers can (1) produce the
required percentage of their electricity from a renewable energy facility, (2)
purchase what are termed “renewable energy credits” (“RECs”), or (3) pay an
alternative compliance payment (“ACP”).
                                                 REC FACTORS

RECs are credits associated with the production of one megawatt-hour (“MWh”) of electricity generated from a
qualified renewable energy generating resources, as defined by state statute. These RECs are then purchased
by electrical utilities in order to meet a state’s RPS Requirements. RECs are therefore commodities; their value
quantified by (1) the state RPS Requirements for which they are purchased , (2) the value of the state’s ACP,
and (3) the supply and demand of RECs in that specific state. Because RECs may be produced in one state and
utilized in another, their values can vary dramatically. As such, RECs have no intrinsic value but typically their
price hovers somewhere below the state’s ACP.

SRECs work exactly the same way as RECs, although SRECs tend to be worth much more because state ACPs for
the SRECs are higher. For example, a homeowner with a photovoltaic (“PV”) panel (commonly known as a
solar panel) on their rooftop could earn one SREC for each megawatt of electricity that the photovoltaic panel
produces once the PV panel was certified and the homeowner became a qualified generator.

Generally, states have different classes of RPS Requirements for different technologies. In 2007, for example,
Washington D.C. required that all suppliers of electricity to customers within the city supply around four
percent of all electricity from renewable energy resources. However, the RPS Requirement was split into Class
I, Class 2, and solar technologies. For the purposes here, the RPS Requirements for solar energy are most
important. In 2008, the DC’s RPS Requirement was .001%, which means that .011% of all electricity in
Washington DC must come from solar energy.

The ACP is a state-specific compliance fee charged to a Supplier by a state for every MWh of electricity the
Supplier is required to produce from a renewable energy resource. As discussed, most states have Class I,
Class II, and solar RPS Requirements, different percentages for each group of technologies. As such, these
states also have differing ACPs for the different classes of technologies. Because solar technology is the most
complex, and most expensive, the ACP values associated with SRECs tend to be highest and SRECs tend to be
most valuable.

Value: Locally, Capital Sun knows of one company offering $200.00 per megawatt hour, which is equal to 20
cents per kilowatt hour. Nationally, RECs values have ranged from a few cents to forty cents a kilowatt hour,
It is still an evolving new commodity in the market.

Summary Maryland Personal Tax Credit for Green Buildings
             Note: As of August 2008, all available credits had been allocated. Those interested in the tax
credit are invited to fill out a pre-registration form on the program website to find out when new credits
will be issued.

Enacted in 2001, this income tax credit applies to non-residential and residential multifamily buildings of
at least 20,000 square feet that are constructed or rehabilitated to meet criteria set forth by the U.S. Green
Building Council or other similar criteria. Newly constructed buildings must be located on a qualified
brownfields site, or in a priority funding area, and not in a wetlands area. Building rehabilitation projects
are eligible if they do not increase the size of the building by 25%, or if they are located in a priority
funding area.

Credits apply to three types of alternative energy sources: photovoltaics (PV), wind turbines and fuel cells.
Tax credits for alternate energy sources can only be claimed if they serve a green whole building, a green
base building, or green tenant space.

The tax credit amounts are as follows:

  * 20% of the incremental cost for building-integrated photovoltaics;
  * 25% of the incremental cost for nonbuilding-integrated photovoltaics;
  * 30% of the costs, including installation, for a fuel cell;
  * 25% of the costs, including installation, for a wind turbine;
  * 6% of the allowable costs for the construction of or rehabilitation to a green base building or green
tenant space;
  * 8% of the allowable costs for the construction or rehabilitation of a green whole building.
  * Allowable costs cannot exceed $120 per square foot in the case of a whole building or base building
and $60 per square foot in the case of green tenant space.

Credits will be allowed for amounts spent on or after July 1, 2001, and will be available for tax years
beginning after December 31, 2002. Applicants must apply to the Maryland Energy Administration (MEA) to
receive an initial credit certificate. This certificate will indicate the earliest taxable year that the credit may
be claimed and an expiration date. Any unused credit may be carried forward and applied for succeeding
taxable years for up to 10 years. There are some restrictions on eligibility, and there is an annual cap on
the total number of credits allowed. These provisions are scheduled to expire on December 31, 2011

* Montgomery County Property Tax Credit for Solar and Energy Conservation

First, only owner-occupants of residential property are eligible. Second, the dollar amount of
the sum of credits granted by the County annually is limited to an aggregate $250,000 for
solar energy systems and geothermal systems and $250,000 for energy conservation
measures. The credits are dispensed on a first-come first-serve basis. If the relevant
$250,000 limit is reached in a year, then the credit applications go on a waiting list and will
be granted in order the following year. The amount of a homeowner’s credit in any tax year
must not exceed the amount of the County property tax imposed on the property in that tax

Geothermal: Ground source heat pumps for heating and cooling.
Solar energy: Photovoltaic and solar thermal collectors for electricity and hot water and
space heating.
Energy conservation device: An energy saving device such as new caulking, insulation,
furnace efficiency modifications, or water heater insulation. Standard household appliances,
such as a washing machine or clothes dryer, ARE NOT eligible for the conservation credit.

Credit Amount. The credit allowed under this Section for a solar energy or geothermal
device is the lesser of: “50% of the eligible costs; or all $5,000 for a heating system or $1,500
for a hot water supply system.”
We think this means that solar energy systems can earn a credit equal to 50% of the system
cost, except for solar water heating systems, which are limited to a maximum credit of
$1500.00. It appears the maximum credit for a geothermal system is $5000.00. Based on
the language, it might be that a solar space heating system can also receive a credit of up to
$5000.00. A property owner cannot receive more than 1 credit per fiscal year for more than
1 geothermal or solar energy device per property.

For all energy conservation devices, the credit is a maximum of $250 dollars per property.
The energy conservation credit is limited to $250.00 per year, but can be carried over for two
additional years
                                      USEFUL FACTOIDS
 Solar water heating systems are sized based on the number of people that live in the house hold.
 The more people the more hot water that is required the larger the system will need to be.

 Federal income tax solar energy credit regulations requires that the system be designed to meet
 over 50% of the projected hot water load to qualify.

  Solar water heating systems can be purchased in DIY kit form for $4,000.

  Solar company Installed systems typically cost between $5700 and $8,500
  depending on the system size and type and difficulty to install.

  Used flat plate solar collectors are available in limited quantities.

                     Suitable for a Solar Energy System

1. Is there an area to put solar collectors that is relatively, or preferably, totally shade
   free? Is there a south-facing roof area to mount the collectors on that has a clear
   “solar window”?

2. The next step is to see if there are any solar obstructions to the south of where you are
    considering placing your solar collectors.
