Is the "energy budget" 250K of a total of 3M?

You should go for a passivehouse, that is realy energy efficient, both
in terms of heating and cooling.

You may probarbly go for solar right now, since you live in a sunny
area and can afford the up front cost of long term savings. If you use
Solar tiles, you do not need ordinary roofing, and can deduct that
against the cost of the solar tiles. You can either cover parts of the
roof with pv or the whole roof.

Try to find some that are cooled in a way that gives you free hot
water and heat. (waterpipes or air below the tiles)

Hydrogen is not a good option, it is very expensive and not too
efficient. At least at present time.

Instead you should go for grid connection (assuming that this is a
built up area). That way you can get cheap off-peak electricity at
night without any hassle, and sell peak electricity at day.
You need to spend a lot less time and money on storage and monitoring
of batteries/hydrogen etc.
You have a place to sell off surplus energy instead of letting it go
to waste /html/ .
You dont have to worry if there is rain and clowds for some time, you
always have electricity at disposal.
