DC form of electricity which has been dominated by AC since its birth is now competing it due to rising share of DC loads such as computers, CFL, and other solid state devices. In this paper we analyze the technical and economic comparison between an SPV based AC grid Vs SPV based DC grid for a far flung rural un-electrified village. This paper concludes that a reduction of 35% load and 42% cost is possible by just switching to a purely DC based grid fed by SPV as compared to SPV fed AC micro-grid. In this paper load requirements in both the systems AC as well as DC based on equipments rating for the same application have been compared. This paper also compares the financial burden for the same amount of load e.g. wind requirement (fan sweep area), lighting lumens, and other electronic devices. Another key advantage of DC grid is that it has low risk of dangerous electric shocks. However, this approach is not very appropriate for fulfilling the luxurious needs such as Air Condition and refrigeration etc. This paper proposes an appropriate techno-economic solution for far flung rural loads especially relevant for 90 thousands un-electrified villages in India.
