In a lot of places blackouts or grid failures tend to coincide with bad weather that doesn't supply much solar charging. The bad weather is quite often windy though so a small wind turbine to diversify the generation sources is helpful.
Living off of solar and batteries means foregoing things like the toaster and the blender.
- gh02t 8y agoTrue, which is why your battery needs to be large enough to supply power during your worst-case scenario for bad weather (or have back up systems like wind/thermal like you mention). You also definitely want a plan for cutting consumption to only essentials during such a blackout. A toaster / blender really doesn't take that much energy; sure they're 500 W or so, but you don't typically operate them for long periods of time. The majority of energy usage in most homes is devoted to heating and cooling, which are high power and run for long periods of time. My point was that it's important to distinguish that long blackouts with severe inclement weather are extreme events, and on average a solar power system should be fairly stable as long as your usage is kept to essentials. I completely agree with OP that you really do have to cut back on power-hungry luxuries for solar-only to be really viable, but you should be able to at least keep the lights on for quite a while. In terms of holding out during more extreme events, yes... relying on any single energy source leaves you vulnerable in that respect.
