Solar powered emergency lights?

[Guest Duncan Mitchell]

Is there any solar powered emergency lighting system that complies with BS 5266-1:2011 for the landlord's parts of a small premises where there isn't an existing landlords electrical supply?

I would have to ask, if you could have a solar powered emergency light how would it work?

In general, an emergency light will come on when there is a power failure to the lighting circuit. How would a solar emergency light "know" that there is a power failure to the normal lights? you would have to run a cable which would carry a mains voltage......which could charge a normal emergency light.

Also you would need to run a cable from each emergency light to a solar panel which is located in view of the sun. (Outside?) This cable could be used to........connect it to the mains.

What if it were an overcast day? solar panels need bright sunshine to work, how would it work at night as there is nothing to charge the batteries?

Although there is no landlords supply, these lights use very little in electricity to charge they could be connected to a tenants supply instead.

What about the normal lighting circuits in these areas the emergency lighting only needs to be connected to these circuits?
