Solar is Cheaper

Solar is Cheaper - In Pakistan commercial unit of electricity costs you 27 rupees/unit. Solar PV Systems can surely give you big savings now. Let me explain you with an example

Lump sum price of a long life solar pv system is 180,000 for 1kva system. This system generates 5 units per day (on average), and 150 units per month. 


Per month electricity savings = 150 * 27 = 4050 PKR

Savings in the 1st year= 4050 * 12 = 48,600 PKR

Annual inflation > 11%

Savings in the 2nd year = (48,600 * 0.11) + 48,600 
                                   = 53,946 PKR

Savings in the 3rd year = (53,946 * 0.11) + 53,946 
                                  = 59,880 PKR

Savings in the 4th year = (59,880 * 0.11) + 59,880 
                                  = 66,466 PKR

Total savings in 4 years = 48,600 + 53,946 + 59,880 + 66,466
                                   = 228,892 PKR

Hence a payback of less than 4 years. From there onwards you will enjoy free electricity.
