Suntech panels are OK

forget the hype about buyback of energy it's a marketing gimmick
unless you are putting in a super 15Kw+ system there is no buy back
The most important solar idea is to reduce your carbon footprint!
which will take about an average 3 years for the system installed.
after that you are generating carbon free energy from the system.
The other main consideration is reduced energy costs
i.e. 2Kw system will reduce your $ power bill average about 25% - 30%
so to recover installed system costs add up the savings $ per year
say $300 per year to reach the installed price say 10 years $3K at todays prices
congrats
