Russel,
Thanks! We're going to look into this when we get done with our wedding and back from the honeymoon. I think it will fit here, but it may stick out a few extra inches beyond the one we have now. Width and Height don't appear to be a problem.
JLM, Last Fall I had a 2.1 kw photovoltaic power system installed on the roof, which seems to provide us with generally all and more of our electrical needs. Grid-tie means that when the panels are generating more than we are using the excess is put back into the grid to be used by others and our electric meter runs backwards when that is happening. In peak demand times (when we are using more than we are generating, or at night) we get power from the grid, so there is never any interruption to service. Essentially it means that we don't have storage batteries and an inverter. We have a smaller inverter/grid interface box that converts the 360 volts DC from the panels into 60 Hz AC and then syncs it with the grid and then runs it through the special net meter, which as I said, runs backwards when we're producing more than we are using.
Yeah, there are a lot of loopholes in the so-called Green building standards, but we designed this entire community from the ground-up to be the best compromise of expense and energy efficiency, and we were actually awarded one of the first EPA 5Star Plus ratings. All of the homes have passive solar design, all have significant southern window area and good windows. We use glue-lams for main structural members to conserve large timbers, 100% recycled blown cellulose insulation (which has a very high R value plus the added bonus of good noise insulation as well., and instead of vinyl or aluminum siding we use cement board which lasts basically forever. All external wood for decks, steps, porches, etc. is Trexx composite wood/recycled plastics, and my home has bamboo flooring on the main level and recycled pop bottle carpet on special low VOC padding. All paints, adhesives, wood finishes and subflooring are low VOC types as well. Each building also has a central boiler for domestic hot water and heat, and is plumbed and wired for future solar hot water panels -- which 2 of the 8 buildings already have in place. That's how you get EPA 5 Star Plus. And, that's only the buildings -- there's more about the layout, the drainage and irrigation systems, etc.
