Low to medium watt panels designed for camping and outdoor applications are perfect for this end and going with an electrical heater means you never have to worry about running out of heat if you need to work inside your garage at night.
Whether they are baseboard fin tube or the freestanding cast iron variety radiators are typically designed for water.
The size shown can heat a small office in the dead of winter as long as the sun is shining or you can build smaller units to distribute around your house.
Electric baseboard heat is a power hog and to get that power through solar or wind would be a monumental cost.
You can build a very effective solar space heater for around 400 in parts.
Solar electric panels generally don t make sense as a heat source.
You can just plug it into an electrical outlet and go.
Standalone heat exchanger one last option is to run the solar heated fluid into a standalone heat exchange in your living space such as a baseboard or wall mounted radiator.
The heating system may be baseboard mounted or integrated into the floor.
Unlike traditional space heaters many solar air heaters typically need to be mounted to a roof wall or window in order to collect the sun s heat.

Baseboard heating is more accessible than radiant floor heating.
There are no pumps fans or moving parts.
However radiators can t be married as successfully to solar collectors.
This has the advantage of not needing to modify any existing systems but it also means having a separate heating system.
Direct collection of heat from the sun is far more efficient than collecting a little bit of the suns energy as electricity and then using that for heat.
