* 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
