* Independence from power companies                            

 * No fuel costs - no fuel source require

 * Reliability - works in all weather conditions

 * Durability - most PV modules available today show     

   no degradation after 10 years of use.    PV                           

   modules have 20-25 year warranties on power 

   output

 * Reduced sound pollution - works silently with no 

   movements
 * Low maintenance costs - require only periodic inspection and occasional maintenance (less than           

    any other power system)
 * Tax breaks and Federal grant incentives - sales tax exemption on PV products
 * safety - no combustible fuels. Very safe when properly designed and installed
 * Electrical grid decentralization - reduces stress on electrical grid
 * Cleaner energy - environmentally friendly, and produces a more consistant output that is less taxing   on electrical equipment.


What Considerations are there in investing in solar energy?


* Initial cost - a greater initial financial     

    investment  than in  conventional power   

    systems

 * Efficiency improvements - A high-efficiency           

    approach to energy consumption greatly                 

    influences the cost effectiveness of the         

    system              

 * Energy storage - The size, cost and complexity of  a PV  system increases if the system  

    incorporates batteries for the storage of energy
 * Variability of available solar radiation - climate, site conditions, and weather require many                        

    system design modifications to optimize power output of any solar-based energy system
