Hi, I have a rental property that has a detached garage.

The detached garage is for the exclusive use of the landlord only for
storage while landlord does up his latest house.

Tenant is happy with that as he does not need a garage.

The garage has a Sub consumer unit that has three MCBs, a 6A mcb for the
internal garage lights comprising of 7 off 8 watt CFLs, (3 in loft space
and four on ground floor)

another 6A MCB for outside floodlights and a 32A mcb for the garage ring
main.

The sub consumer unit is fed from the main house. The tenant has turned
off the power to the garage from within the house. Clearly the tenant
doe snot want to pay for the electricity that the landlord may consume
for4 lighting up the garage.

Both landlord and tenant are happy with the current arrangements.

However, the landlord would like to make provision for lighting only in
the garage with a independent power supply.

The landlord always uses a car to get to and from the garage.

The chouices the landlord has so far for powering up to 56 watts of CFL
lighting is:

1. fit a changeover switch between house and garage and use a Honda
generator.
2. fit a changeover switch between house and garage and use an inverter
powered from the car's cigar lighter socket.
3. Fit a changeover switch, Fit solar panels and a leisure battery and
an inverter.
4. Install some 12 volt lighting, Fit solar panels and a leisure battery
5. Install some 12 volt lighting, and a lead to run from the car's cigar
lighter socket.

Option 5 and 2 appear to be the two cheapest options.....

1. is probably too noisy for the neighbours

Options 3 and 4 seem the most expensive....

Discuss.....

Leisure battery and CFLs. Lantern for when LB is being charged, or if
that is a problem, two leisure batteries. (It's how I light my stable
block and tack room).
