We were originally going to build a cob house but have decided to turn our shed into the tiny house we've been wanting. It's about 155 square feet. It needs some work done: new roof, new floor, new back wall, outlets added (the shed is already wired for electric but only has a couple of outlets so we'll have to add a couple more here & there), insulated, windows, new door and then just the cosmetic stuff like interior paneling, flooring laid down, paint, etc. It's only for 2 people, 1 dachshund & 2 cats so we think 155 will be fine for us. We're going to continue living in our trailer right now until we get it built & then tear down & scrap the trailer for whatever $ we can get out of the aluminum & frame. It's a 16x80. But here's where our question comes in: would it cheaper for us to continue to use power through Alabama Power or should we invest in solar? What all would we need solar wise? And how much would solar cost us given our 155 square feet? We'd have a normal size fridge, an oven, 1 over head light & a couple of lamps, we've got 2 computers and 2 cell phones to charge & our tv/dvd player. Right now we pay about $230 a month just for power & my grandparents pay less than $100 for their stick frame house & they have about 3 huge freezers that are always running, lights on all day long and a ton of other stuff that we don't have & their bill is so low! Is it safe to assume that once we start living in this tiny shed that the bill will decrease dramatically & we won't need solar or should we go solar? We live in a sort of hole where only a couple of spots get nice sun exposure. The shed is surrounded by trees but we can always cut some down. What would be cheapest way to heat the shed & keep it cool? Should we use some sort of rocket stove & just make sure to run the chimney up first before we add the new roof? Thanks guys!!
