Solar powered emergency lighting

[Guest JanR]

Can emergency exit lighting be solar powered on a small block of  5 purpose built flats over 3 floors.

Probably not, how would the lighting activate upon mains failure and would the UK weather ensure the units are always charged to 3 hours?

If part of a proper solar panel system covering the whole roof then there may be possibilities, but I'd be surprised if the self contained stuff as seen on Amazon would be suitable.

Just to add, if you could have solar emergency lights, what would happen at night? There would be no sunshine so the lights would illuminate flattening the batteries making them useless.

Not to mention that if the solar panels were roof mounted, who would clean them and remove the snow in winter.

Solar EM lighting sounds a good idea, but the reality is, it's not possible and with technology, as it is it would still be more economical to buy mains operated EM lights, especially if you consider safe lincs can supply EM lights for less than £16.00 each  Click here (Installation NOT included)
