* 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
