Solar Panel __ Personal Experience Why don’t you shut down the light before leaving the room!... Do not turn on the air conditioner…! My whole salary will be finished, oh these bills! … Are you facing the same problem at your home too? Rate of electricity is increasing day by day so the only solution came to my mind was “Solar Panel” and it worked absolutely according to my expectations. It is one-time investment So, I bought 30 plates of 15KW and set the whole system on roof. Now all electrical appliances of my home are on solar panel, including 6 air conditioners. It shouldn't come as a shock to any individual who has done some research about solar panels, the amount of daylight where you live is the most significant factor that will decide the measure of solar power that your solar panels are creating. 15kW or 15 kilowatts is 15,000 watts of DC direct current force. This could create an expected 2,000 to 3,000-kilowatt hours (kWh) of alternating current (AC) power per month. Photovoltaic cells absorb sunlight and generate direct current (DC) which is then converted into Alternating current (AC) through inverters. Following are few steps that how this technology works. SP inverter DC AC Electricity flows through house, powering electronic devices and excess electricity produced by solar panels is fed to the electric grid or can be stored using battery. I send my excess electricity to WAPDA and now my bill is zero and sometimes WAPDA have to pay me, so they adjust that bill for next months. In a nutshell, I am using free electricity whole year. I can provide solar plates details (from where I bought and price) in comments section if anyone is interested. (Nimrah Saeed)
