For your lighting I would go with high efficiency LED lighting replacement bulbs. Some of the LED bulbs are getting to 60-70 lumen per watt efficiency and compete with CFL bulbs although are still more expensive than CFL (the local Electricity supplier gives CFL bulbs away free of charge)

Each LED Bulb consumes only 3 Watts each

A typical room can be illuminated for around 10W (500-600 lumen) total for adequate emergency lighting. This would compare to 60-80W of Halogen or conventional tungsten lighting and 12-15W for CFL.

To power the lighting an emergency portable 40ah SLA battery with 300 Watt inverter can be used. (UK equivalent of the Xantrax power packs available in the US)

To charge the power pack a 45W or 60W Solar Panel kit could be used in conjuction with a solar charge regulator and setup quickly in an emergency.

A good demo is shown here for the 45W Solar Kit

A typical setup using a 40ah SLA battery would power a 10W lighting system for continuously for around 35 hrs (or around 3 hrs with a single 100W Tungsten bulb) without any solar charging, and almost indefinitely with the solar panel.

You could of course scale up the whole generating your own electricity using Solar PV and the only thing you would have to worry about would be this
