Solar soil warmer ?

You can use the last project as a template for many microcontroller projects, but heaters generally use a lot of power!

gravityisweak and bekathwia are right, electric heaters use a lot of power, and the system as a whole would be very inefficient. Try using the same concepts from the solar balloon project for a solar soil heater.

For a project like that you may want to try a solar system that uses the sun to directly heat some air or water, then uses that heat to warm your soil. Similar to the soda/beer can solar heaters.

When using a solar panel to run an electric heating coil you will have massive losses of efficiency.
