6. Technical Considerations
 Factors that must be considered in evaluating
implementation of alternate energy
 Availability and Consistency of solar power
 Available Land
 Rebates
 Tax credits
 Utility Company’s Rules and Regulations
 Cost of material and labor

7. Financial Considerations
 Initial Capital costs
 Costs of Feasibility studies
 Design costs
 Real Estate costs, Survey costs, Legal fees
 Permitting costs
 Equipment procurement and Installation costs
 Operational and Maintenance Costs
 Energy costs
 Manpower
 Equipment maintenance/replacement
 Other operational costs

8. Life Cycle Costs
 Accounts for total costs of facility/infrastructure
ownership
 Includes construction, operating, maintaining, and
disposal of various components of the
facility/infrastructure
 Life Cycle Costs considerations are specially useful
when there are more than one alternatives available to
achieve similar project goals and performances
 For alternate energy considerations, the initial higher
capital costs can be sometimes justified evaluating life
cycle costs.

9. Solar Energy - Basic Facts
 On a clear day, on the surface of earth, at noon, the direct
beam radiation will be approximately 1000 Watts/m²
 Today’s commercially available PV panels generate 12 to 16
Watts/SqFt and have a 12% to 17% efficiency
 Average PV generation cost ranges from $4 to $6/Watt
 An on-grid solar energy system is a revenue generating
investment, either through lowering electric utility bills or
by selling power to the electric utility companies

 An on-grid solar energy system is a revenue generating
investment, either through lowering electric utility bills or
by selling power to the electric utility companies

10. Solar Photovoltaic Systems
 Solar panels convert solar energy to Direct Current
(DC) electricity
 Electrical DC energy will then be converted to
Alternating Current (AC) electricity using inverters
 The AC current subsequently connects to the load
(shared by the Utility) via a controller
 The rule of thumb is 1 kW of power is required to run a
1 HP pump.

32. Rebate Programs
 The rebates change based on size and location.
 They are also in effect for a limited time.
 Needs to be studied on a case-by-case basis.
 Generally, rebates range from 10% to almost 40%.
 The higher rebates are for “very” large projects.

33. Closing Thoughts..
 Implementation of Alternate Energy is very feasible from
financial standpoint
 Initial capital investment may be needed, but costs
incurred can be recovered overtime
 Active funding opportunities are available through various
government agencies
 Rebates are available from utility providers; however needs
to be considered on a case-by-case basis.
 A Preliminary Evaluation or a Feasibility Study must be
performed to determine basic technical and financial
feasibility.
