A
solar powered hotplate is an efficient and environmentally friendly
way to heat food in remote locations. Because it is solar powered, it
does not need to be plugged into the electrical grid to function. In
fact, it is so energy efficient that many people use it around the home
to save on bills.
Of course, it is good to make sure that the heat being created by a
solar powered hotplate is being well-conserved. After all, though solar
energy is free and unlimited, the food will be cooked more quickly and
efficiently with some additional energy optimizing tactics.
Also, the amount of energy that the battery of a solar powered hotplate
can store is not unlimited- nor is the daily time allowance for energy
from the sun to be harnessed.
Proper insulation is the way to keep the heat where it is needed. The
goal is to warm the food, not the patio or outdoors. A way to do this
is to keep the hotplate on its lowest setting and use a cover made from
aluminum flashing. The cover should reach all the way down to the surface
of the hotplate. It is also possible to use a cover made from a large,
overturned saucepan. In this situation a slot should be cut into it
in order to fit the handle of the smaller cooking pan.
