Let s say you could achieve an overall solar array conversion efficiency of 20 and you want to generate 1 2kw of power to run a space heater.
Run a space heater off a solar panel.
This allows for the inefficiency of the conversion storage units might i suggest a propane kerosene or diesel space heater instead.
Although it will need to be placed in a space where it can collect sunlight it will function even in partly cloudy conditions.
What can you run with a 100 watt solar panel.
Most electric space heaters are a minimum of 1000 watts of 120v power.
The heater is most efficient in rooms that are 150 square feet or smaller.
You would need at least 1500 watts of solar a charge controller batteries an inverter.

Or a third option would be to convert a traditional electric space heater to solar by plugging it into a portable solar panel.
The beginning stages of research with solar power is always how much power with how many panels.
There are no pumps fans or moving parts.
It s a question that comes up often for those looking into smaller scale solar installations.
Over the course of a sunny day this system can heat a room at zero cost.
You can build a very effective solar space heater for around 400 in parts.
So the total sun power hitting your photocells times 20 is the amount of electrical power your photocells will generate which needs to be 1 2kw.
It s definitely a smart way to go.
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.
