How much can I save by using a pv system?
A 10% efficient PV system will generate up to 180 kilowatt-hours per square meter . a PV system rated at 1 kilowatt will produce up to 1800 kilowatt-hours a year . allowing for a loss of efficiency of less than 1% per annum, such a PV system could generate close to 36000 kilowatt-hours of electricity over 20 years and close to 54000 kilowatt-hours over 30 years . this means that a 1kw PV system generates more than US$10000 worth of electricity and various other grants and tax incentives are available that improve the economics of PV.

How do I know if I have enough sunlight for PV ?
A PV system needs unobstructed access to the sun’s rays for most all of the day . climate is not really a concern because PV systems are relatively unaffected by severe weather . in fact , some PV modules actually work better in colder weather . there is enough sunlight to make solar energy systems useful and effective almost every where in the world . most homes have adequate roof apace for a PV system , and this can be complemented by integrating the system into walls or by using modules to cover a porch or patio in the backyard .
