Hi all, I made errors in my hasty earlier mail.Kindly accept my apologies.For 100w pv supply, 1h run supplies 0.1kwh energy.1day supplies 1kwh assuming 10h sunlight in tropics.1month supplies 30kwh. A 120kwh/m moderate user needs 4 modules costing usd 960. At usd 0.08 per kwh for grid electrical cost or usd 9.6 per month payback of cost is 100 months which is life of pv.We need pv modules at less than half the current cost.
