for solar: Much simpler to use a PV panel to generate, one or more
12V batteries to store, and 12vDC lighting and heater units. No
inverter needed unless you want to run a corded drill.
a century ago, the Delco light plant worked in a similar manner. A
generator, generating DC, batteries, perhaps a wincharger for "free"
electricity, Low voltage DC incandescent bulbs for light. Perhaps
a DC motor on the Maytag washing machine. It worked in homes and
farms for decades before "lectricty" came on poles.
As practicality, bury a 12-2 WG type UF wire with a trenching spade
and quit whining.

A solar panel will generate direct current (DC). A power
cell - and therefore a battery - can only store DC. If you
need alternating current (AC), then a converter is needed.
It is called an "inverter". Small ones (low power) are
pretty cheap. Big ones are not. Ideal is to get an inverter
with a power rating close to your power needs. If you have
80 Watts of seedling heaters, get a 100-120 W inverter, not a
The process of creating AC from DC is not perfect. Thus to
get 80 W of AC will typically require 90-110 W of DC.
The capacity of the photo-voltaic panel, capacity of the
battery, and the power rating of the inverter all depend on
the size of the load.
