It's finally time for a new roof, so I'm going solar this year. I am tickled to see the advances in PV tech since last time I looked at it (microinverters/power optimizers, 20%+ efficiencies). I am getting in just in time to get 1:1 net metering, so no batteries for me. I have a generator for outages. I like the idea of onsite storage, but I don't like the idea of replacing batteries regularly. I am getting an oversized system with a view towards adding a split system, electric DHW, and hopefully electric vehicles at some point. The whole thing is adding up quickly ($13k roof, $23k for a 20 panel PV system, plus the house needs a new main lug and 200A service entry upgrade...). It'a still looking like a good deal after the tax credits right now. ROI at my old rate of power usage is about 8 years, and I plan to about double my usage (I currently heat with 100% wood and don't use AC, oil hot water heater), so you could argue that it's significantly lower. Anyone have any gotchas, tips, or things to consider before jumping in?
