I would get a LDA flat in Lucknow in Gomtinagar Extension area by end of this year. I would like to have the Solar Energy for light, ventilation, water heaters ad Air Conditioners at my residence.The available data in market related with availability,cost, subsidy, incentives,quality, guarantee and serviceability of the full apparatusare too confusing to believe and take a final decision. May I have all necessary information on the subject to go ahead? Will the wiring, fittings etc required for normal electric fittings be common for solar energy also, or I will have to have separate syetem? Will it be advisable to avoid having the normal electric connection and keep only the solar system ? Which alternative would be cheaper and? What about the maintenance cost?
