We run our washing machine off the solar panels (400 watts in 4 panels currently) The Candy washer has a setting for 'use whatever comes from the tap' so no heater involved. Washer draws only about 260W so is easy off our 1500W inverter on a sunny day. (It's all very well having big inverters but can the engine/alternater keep up with demand?)
We use the genny only in winter and the engine about once every two weeks for an hour to go get water and empty tanks.
Without the solar our batteries would be run low every night - shortening their life.
Without the solar we would have double the petrol bill
Without the solar we would be lugging the generator on and off the boat every day, all year AND listening to the thrumming of the thing not to mention annoying neighbours
Without the solar we would be polluting twice as much as we currently do.
Solar panels need no servicing, no oil changes, no carrying about, no worrying about whether they'll start. We could also go and buy an extra panel at any time and make ourselves even more smug about our (semi) free electric.
Oh and I forgot - we are big users and 100% off grid with an electric fridge, all the gadgets and we hardly ever give our battery levels a thought for about 5/6 months of the year they are always above 12.2V
The less we rely on generators the better and it's just so easy with a bit of thought. One thing I can't help with is the hair dryer! only use during the winter?
