Today when i was eating at this little place i like in NYC i was reading a copy of home power magazine i had picked up to read about this new solar panels that are comeing out of Germany and should be on the market in about two or three months time frame.. The guy next to me said that no house could be run totaly off solar in this country and i was looking at the guy like ok explain your self and he was trying to tell me his knowage of how solar works .. i lay out how the appliances work in a off grid home and how many watts your battery system has in it along how many watts are draw off the bank when it going at full peak load and with the size of the battery bank and how it wired in a 12.volt 24.volt or 48 volt string set up and the size of the solar panels that you need along with the prostioning of them to get a clear veiw of the sky and mounting them on a sun tracking device to get the most out of the sunlight to charge the battie and what size of inverter to run the 120.volt appliances off the battery bank along with makeing sure they are enegry star rated to get a low wattage draw from the of the system then i asked him about wind turbine and are useing a small less than 400.watt turbine or are your up to a 5kw turbine system to produce the power from the wind and how much hieght on the turbine do you have and are you a good spot that has wind comeing off the ocean or river area also .. The guy get this deer in the headlights look and then i asked him where did he hear or who told him that a home could not been run completely off grid ..he goes i have been reading about solar and wind .. I basically go you need to your local library and check out some newer books on some solar and wind because they have come along way since what ever your books that you have read .. After the guy leaves and i finishing up my lunch the lady who took my order goes you really know your stuff about solar and wind and i explained to her i live off grid in a place in Sunny Az and i learned a thing or two about the basic of solar and wind and belive me it cost me enough money to know what works and what does not work in some areas .. I told her the basic idea is go to the library and check out books on the subect of wind and solar and RV and sailboat how to electrical and other subect that comes up inside those areas ready everything you can on those areas and reread them again and then sit down and design your system and then figure what you what to give up in the way of modern appliances inside the place and the one you will not give up and go from there .. When i went back later on tonight she was at the counter with about four or five books on those subects we had talked about and she goes you know your right about the money on the mistake that you make when you do not think it through.. I did tell her some areas of the solar and wind system for your home it best to get with a company that does that for a liveing and they can really keep you from beening really spending more money than it needed in some areas of trying to run a off grid home ..
