Panels on my roof reduce my electricity costs. Put in a field by someone else does not. My panels are not visible from the street and will have paid for themselves within a few years, so there isn't really a reason not to. I think 30-40% of homes in my city have panels on their roof. This ignores any feed-in tariff which is declining, though there were early adopters with a locked-in rate who wouldn't have paid for electricity for years now.
