Is solar a good investment for my apartment building?             
As a property owner, have you asked yourself that  question? There is a lot of
conversation about going green and reducing carbon emissions. 
 As a business owner the real consideration is:  Will this be a good investment?  Will it increase my cash flow and  property value? 
Will solar work for my apartment building?                  
If you answer yes to the following questions, then solar is a good
investment for you.      
1.Does your building have  a centralized water heating system?      
2.Does your company or its shareholders pay federal taxes?      
3.Does your company or its shareholders have a tax liability that  can utilize equipment depreciation?                
Since most apartment buildings have  centralized water heating systems, the  gas bill is paid by the building's owner. 
In this article we are going to focus on solar hot water systems.   We'll give you a brief history of how solar thermal has greatly
improved in the last 20 years and we'll explain the three types of systems that  can be used for apartment buildings. 
We'll discuss the current available tax incentive, grant, rebate and
other options that make solar a good investment.                 
Solar hot water was widely adopted in the 70's and early 80's during the  Carter administration. 
The early systems used the building's potable water directly in flat-plate collector and  are referred to as "open loop" systems. Many open loop systems failed prematurely due to poor design, freezing weather conditions and calcium  building up in the collector from the potable water, but great advancements have been made in the last 20 years. 
SOLAR THERMAL DESIGNS:                 
Today's solar hot water systems have addressed issues by changing to a "closed loop" design that re-circulates the same fluid thru the collector loop.  There are three main types  of closed loop systems: closed loop glycol, passive system and drain back
system.     
Closed loop glycol  systems are active systems that are widely used. Non-toxic glycol is  used  as the heat transfer fluid in the collector. It re-circulates in a closed loop  to protect against freezing and mineral buildup. Its drawbacks are the extra  equipment needed to deal with stagnation (overheating in summer) and glycol  has a less efficient heat transfer than water.        
Passive systems consist of a combined collector and tank  design.  This eliminates moving parts, like a pump and controller, making the system less complex. Disadvantages  are extra weight on the roof (100gallons of water weighs 834lbs) and no  stagnation protection. If there is low or no demand in summer, these systems  will overheat. ·        
Drain back systems are  active systems using pumps and controllers. These systems have freeze and  stagnation (overheating) protection. Simply, when the pump stops all the water  in the collectors drains back to the system's tank. These systems are one of the  easiest to maintain and operate. The drawback is that not all buildings can  accommodate this system. In order to drain properly the collector supply and  return line must slope to the tank.                   
The systems described above are pre-heat systems for the building's  existing  water heating  system.  The solar collector  pre-heats the water before it enters the existing water heater so the water  heater doesn't have to run as often.  If there are multiple days of cloudy weather with no sun your tenants  will still get hot water from the existing water heater.                
There is no one system that will fit every application but the three
systems described will cover almost any application and all are dependable.  A well designed and properly installed
system will give many years of service.
CASH FLOW                 
A solar hot water system can increase your cash flow by reducing your  operational expenses.  Building  owners that take advantage of the tax credit or grant, CSI rebate and equipment depreciation and qualify for a loan at 6% or less are cash positive from day
one.  The energy a solar hot water  system offsets should be more than the loan payment thus increasing cash  flow.
PROPERTY VALUE                 
A solar hot water system will add value to your property but your
property taxes will not increase. 
Section 73 of the California  Revenue and Taxation Code allows a property tax exclusion for certain types of  solar energy systems installed between January 1, 1999, and December 31, 2016.
Qualifying active solar energy systems include solar water heating systems and  active solar energy systems.
INCENTIVES                 
Currently the following state rebate, federal grant, tax credit and
equipment depreciation can be used to maximize return on investment.        
30% Federal Tax Credit:  The credit is equal to 30% of the total cost of the system with no limit. The credit can be used up to 2016 if credit cannot be recovered in one tax filing.  Eligible  solar energy properties include equipment that uses solar energy to generate  electricity or uses solar energy to provide hot water for use in a structure.  This credit will continue to be available for solar systems placed in service on  or before December 31, 2016.        
1603 Federal Grant:   This grant pays cash  in lieu of  tax credit and is  funded by the stimulus plan.  Unlike the tax credit, the grant  requires an application (with several simple requirement) be completed and  filed.  The cash amount is 30% of the total cost of the system with no limit.  The 1603 Grant is available only to
projects that are at least 10% complete by December 31, 2011 and claimed (application completed and filed) by October 1, 2012. In addition to the  application, you must continue to submit a performance report annually for the first five years of the system. 
Projects started after 2011  will no longer have this option.        
CSI Rebate: The  California Solar Initiative is a rebate program to promote solar in California.
This program is funded by SDGE, PGE, SoCal Gas & Edison rate payers. If you check your SDGE bill, the Public  Purpose Program charged to you is used to fund all energy rebates. 
The Solar Thermal Program has a $350million budget to be used for solar  water heating systems, training and marketing. Rebates vary depending on type of  system, collector location, shading and other design factors. Incentives will  decline over time as the program meets certain benchmarks so early adopters  receive larger rebates. 
Everyone who pays a gas or  electric bill pays into this program but only a few wise investors will get  their money back.         
Equipment depreciation:  As a business, apartment owners enjoy a benefit not available to homeowners,equipment depreciation.  The benefit of equipment depreciation can greatly reduce the total out of pocket expense on a solar system. Consult with your tax advisor  for your specific situation.
FINANCING :               
In this economy, when cash is tight, there are a growing number of  financing engines for solar hot water and solar electric.         
Energy efficiency loan  programs with low interest rates are offered by many  banks.        
Power purchase  agreements (PPA's) offer no upfront cost to the customer.   A PPA is a lease-to-own  program where the customer agrees to purchase the energy produced at a  discounted rate for up to 20years. PPA's are widely used in residential solar  electric systems and are becoming available to the solar hot water  industry.                      
So is solar a good investment for your property? Considering the gas bill  for your building will never go away and will probably increase over time. With  the available incentives, installing a solar hot water system could be one of  the best investments you make this year.
