Solar Electric Space Heater Easy DIY! Parabolic 55V DC direct power by solar panel array #solarheat
May 9, 2024
A common parabolic infrared space heater can be easily converted to ~55 volt direct solar PV-DC operation (PV to Load / PV2L) directly consuming DC electrical power from a solar panel array. Anyone with basic electrical, safety protocols and solar knowledge can convert this heater to DC. PV2L heating is a simple and robust way to consume excess solar power to heat ones home.
But
converting AC space heaters to DC can be tedious and difficult. Usually a rewind of the heating element would be required for efficient operation. For example, I
often rewind Quartz Infrared heating elements in my heaters to match the low voltage of my solar
panels. But the heater shown in this video requires no heating element rewind at all - in fact the
element is sealed and cannot be modified.
Many DIY solar power enthusiasts have solar panels sitting in the sun underutilized. In fact they are just sitting there aging, when they could do something useful. After the batteries are full, why not simply burn excess solar power in a convenient and attractive form? That would be a DC space heater. Unfortunately these heaters are not currently on store shelves, but with care and attention, it's possible to convert and operate your own DIY DC space heater to help heat a home or workshop. The heater shown in this video is one of the cheapest on the market, yet the easiest and most friendly to convert to DC.
Please note that you should not attempt a project like this without basic electrical and solar power knowledge, plus understanding of the risks involved. A heater that has been modified loses its UL and safety rating. If a person is responsible and technical enough to understand what he is doing, then these heaters should be safe to use to heat a space with proper care and supervision.
Finally an easier way to enter the world of PV to Load space heaters - you just need some basic
components for the heater:
1. Crimp connectors
2. PV rated wire
3. Solar Photovoltaic DC rated circuit breaker
4. A couple of DC-rated tip over / tilt switches
5. An extra thermal fuse or over temperature protection device in series is highly recommended
In the video I show a simple wiring diagram. It's a basic and simple circuit with the 55v DC solar array, PV DC breaker, heating element, tip over switches, and thermal cutout all wired in one series loop. The sun shines, the heating element glows, and you get heat. No rewinding of heating elements or calculations. It doesn't get any easier than that.

Thermal fuses: check heater temp at top, and spec a fuse that is somewhat above that temp. I have not yet finished testing these fuses and it's unclear what temp rating would be safest.
