Do you mean, 100:65? Bruce Roe

Thanks Neoh for you calculation.
Do I have to deduct that $0.15 value with 35% to 0.092.
5000 x 0.092 = 460, thus 8500 / 460 = 18.5 years if one theoretically export 100%

edited to answer foo1bar:
electricity here is cheaper than surrounding countries :/

If 100% export during the day, and a 35% "donation" to the grid, then yes break-even is about 18.5 years ( ouch ! )

Bruce Roe,
Yes 35% immediately deducted by the grid company if you "export"

so lets say pv production 100 and 10 used then grid "pay" you 90Kwh x 65% = 58Kwh

Why not gridtie?
