    You don't need to convert the enlarger. Just get an inverter. Yes it adds cost but then you'll be able to use anything that doesn't exceed the power output of the inverter.

    Expensive depends on the other options. If you don't already have a power line run to the house the cost of just running the line can be pretty expensive.

    That is an option, no doubt. However, an inverter is expensive, and on a very small scale such as I have suggested, not particularly effecient.

    Between panels, batteries and even cheaper stuff like wiring is a small inverter really going to bust the budget? One small enough for an enlarger shouldn't be that expensive. If you convert the enlarger to 12v wouldn't you need a 12v timer? Plus it would be usefull for any other need. Blackout backup.

    The last I looked into this (about five years ago), the companies that were making photovoltaic shingles were putting a lot of effort into coming out with products that resembled conventional shingles of various designs. At that time, none could be mistaken for more conventional shingles, but IIRC the goal was to have something that would be nearly indistinguishable once installed. Thus, it's conceivable that they'd be suitable even for historic buildings before too long, at least if the concern is maintaining the historic appearance of the building rather than a strict use of original materials.

    I would suggest you consult this link for a reality check concerning the cost vs. capacity of such systems.

    A quartz clock clicks once a second, which is great for timing exposures and dodging and burning. It has its own small battery which lasts a very long time. Low voltage LED safelights can be improvised.
