One idea I've found that works, provided this is possible (i.e. you own the property), and one has the electrical ability, is to have a dedicated circuit for the little devices that comes from an inverter  and a set of batteries that charge from a PV panel array.
This doesn't have to be expensive. A common setup winds up being two 6VDC golf cart batteries in series (12 volts total), 2-3 PV panels, a decent charge controller , and an inverter. This won't run your air conditioner unit, but it will be big enough to handle a number of low amperage devices, and one can build a decent setup for well under $1000.
In fact, I did a jerry rigged setup to light a shed on the far side of a friend's farm using a cast off extension cord (it had the proper gauge wires when stripped), a cast off 200 watt panel, a $8 PWM charge controller from eBay, an old deep cycle battery, and a DC-DC converter so I could use some 340 lumen SunJack LED bulbs (with built in switches) that run from a USB port. All of this cost well under $100. The SunJack LED bulbs would run 8-10 hours on a 1.2 amp (or 12,000 mAh as the packaging says), so a 200 amp-hour battery that only has 50-75 amp-hours left can run the bulbs for a very long time without solar.
Another added benefit of having all the devices on their own circuit is that they are essentially on a UPS, so if power fails, they will still keep running.
: Don't skimp here... buy a reliable PSW (pure sine wave) inverter, and go for a 1500-2000 watt model even though running at full tilt will discharge the batteries quickly. This is so that if one plugs something in that has an inrush current (refrigerator compressor, microwave), the inverter can handle it.
: You can go with a MPPT controller, which allows for higher voltage panels (as it converts the voltage higher than what the batteries use into a lower voltage with more amps), or have more panels to handle how a PWM controller "lops" off any voltage it doesn't need.
