*Independence from power companies                            * No fuel costs - no fuel source required

 * 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
 * Low interest rates on loans - offered by loaning institutuons for PV systems and installations
 * 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 Choosing Photovoltaics?

 * 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
