Off Grid Solar Powered, Garage Type Outhouse Grow Room

One of my worries is how much space is needed for the battery bank
and other equipment involved with generating and using Off Grid Energy???

I don't want to construct a 20 x 10 Cinderblock outhouse
then need to use a third of it just to house the power supply....?

Also, it needs to be as reliable as piped in, off the grid, energy.
In fact, it needs to be more so!
It needs to supply a constant supply of smooth running power
just like the usual household has.
BUT not be susceptible to power cuts
(which. despite being rare, can still cause devastation to a grow!).

I plan on constructing an outhouse that, from the outside, appears to be about 5ft high
but it will have a 24" dug out interior.
Aluminium ducting will run through dug out troughs
So the heat will vent well away from the construction
and, any heat not dissipated during its 10ft cold tunnel journey,
will be expelled under compost heaps or similar objects of subterfuge
(Outdoor pot bellied stoves, hollow underside of a raised bed... etc).

The outside will appear to be a simple cinderblock (UK breezeblock) construction
Inside will be lined with thin, boat style, wood cladding.
Between the outside blocks and the inside wood lining will be insulation.

The roof will be aluminium sheeting, insulation, internal wood.
Plus, of course, the Solar Panels.
Guttering will catch rain and, through downpipes, harvest it into barrels.

ANY FURTHER IDEAS
OR CONSTUCTIVE CRITICISMS ARE VERY WELCOME.

Gonna need more panels than your roof will hold. Size of PV system is deyermined by the loads being fed.

Lets do math for a single 1000 watter in veg. 1kW x 18 hours a day means you need 18 kWh of power each day. For sake of these numbers lets assume everything is 100% efficient. Panels only put out full rating when aimed directly at sun so best case maybe 5 hours a day then the rest of output is diminished. Lets say you have 10 x 300 watt panels charging a battery bank. Say 5 hours of full sun 15kWh is stored. Perhaps this would supply 18kwh daily if all days are sunny.

So you see the issue. Your gonna need thousands in solar.
