Yes, with battery bank.
solar panels to controller to batteries to small appliances/lights/small inverter < that provides 240volt starter for generator to run big appliances.

For small solar you're going to need batteries, although I have seen an interesting article posted on Low Tech Magazine that talks about just using what you get when you get it. Good old fashioned lead-acid batteries are cheapest and work well, but you really only get to use half the "gas in the tank" (50 per cent depth of discharge) before you're into "batterycide" territory. But a lead acid battery bank won't spontaneously combust, either.
Figure your load carefully. Which is to say double it and add fifty per cent to arrive at a working estimate.
Seek out controllers and inverters that are guaranteed not to emit radio-frequency energy at wavelengths used by communications. If you can, run as much as possible on DC. That may involve getting lighting devices intended for low voltage DC. (I'm not "Edisonian." Simply, you're losing energy with every conversion. "Eating low on the food chain" is better in this case.)
Our 11-kilowatt solar-tracking array would need another house to hold batteries, so for that project we're definitely grid-tie.
O.H.
