@current currency exchange rate - a 1 KW full load solar system for 8 hour back up cost approx Rs. 350,000. It includes 12 solar panels 6 batteries inverter, charge controller, & a circuit breaker cut out db.
@Op would you please explain what do you mean by BEST Investment ?? Globally Solar enerygy users get a carbon subsidy from every kilowatt/ hour usage ... ironically in Pakistan Govt NEPRA charges TAX on your own domestic generator larger then 5KV let alone allowing a subsidy.
ONE solar panel manufacturer in Hattar is enjoying monopoly since past 6 years no other manufacturer has been able to get an NOC for putting up solar panel facility the ownership is of an EX-General and 75% of production is smuggled to Afghanistan only 25% is sold in metros of country.
since China opened up shenzen a flood of B quality ( written wattage 120 watts - actually producing only 90 watt ) solar panels are in Quetta & Peshawer price is 50% less then the local manufacturer.
wake up get your facts right the only right investment is in GOLD because thats where you only pay TAX <zakat> to ALLAH (swt) and it never depreciates and if managed carefully there is no encroachment like people does on vacant properties.
