Advantages of a PV Roof-Top Power Systems:



Solar power feeds directly into existing building switchboard:
     No costs for grid extension, marginal costs for grid connection

PV Modules safe and secure on roof-tops:
     No or little security needed, e.g. no guards, fences, CDTV is o.k.

No expensive substructure foundation required:
     Roof-top mounting systems specially designed for all types and makes of roofs

Advanced roof-top mounting system keep roof skin intact:
     Modern mounting systems do not puncture the roof

Minimized O&M costs: no vegetation control and less cleaning
     PV modules tend to keep cleaner on roof-tops than on ground

Little impact on power grid, tends to stabilize voltage levels
