The recent cost decline has made solar PV much more affordable and the technology breakthrough has made it possible that now we can run our existing air conditioners silently without any DG set. What you need to do is just install a solar PV system on your rooftop powering the air conditioner through solar.
I live in Gurgaon and we are accustomed for regular power breakdown and sometimes like me have no choice, but to install a diesel generator set which is not only costly affair but also noisy solution. Recently I have installed a 2 Kw solar PV system on my rooftop, which is efficient alternative to run my air conditioner and all other house hold appliances. The critical part is to run the air-conditioner through solar PV which requires a specialized inverter solution which is capable to take high starting current for the compressor of the air conditioner , I have installed a 6Kw inverter which can take load of my two air-conditioners and also provide power for fans and lights. There are various inverters available in the market and we need to be careful in selecting the inverter for a system, it is advised that the inverter has dual inputs, so that in the event of cloudy day the batteries can recharge through grid electricity. It gives a great feeling when we realize that a comfort we are getting from solar electricity which is silent as well as economical solution. I am thankful to team of greenfirst power ventures helped in installation of this system at my house. Complete 2kw system with 6kw inverter and 8*100Ah battery bank costed me about 3 lakh rupees. Although bit costlier compared to typical DG set in terms of initial cost, considering no maintenance and no fuel we find cost effective solution to get rid of the grid power and become self sufficient to meet my own house electricity requirement. We are leaving a few pictures here to our blog readers, appreciate to help anyone to install similar system at their home.
