AI Takeaways
- A solar-powered heater uses solar panels to directly convert sunlight into heat, while a solar generator stores solar energy in batteries and then powers electric devices like space heaters.
- A solar-powered heater is built only for heating, whereas a solar generator is versatile and can power different appliances, including heaters, lights, and electronics during outages or off-grid use.
- Most electric space heaters use between 750 to 1,500 watts, though larger units may require up to 2,000 watts. Always check your heater’s label to know the exact wattage before pairing it with a solar generator.
- Running a 1,500-watt heater for one hour costs about $0.26 with grid electricity, but with a solar generator, the cost depends mainly on the upfront investment in panels and batteries, since sunlight is free.
- How much solar power does a heater need.
What Is A Solar Powered Heater
Solar-powered heaters use solar energy to warm air, which is then blown into the tent or room you want to warm. A solar heater comprises solar panels, a duct system, and diffusers. Some heaters also have fans, while others depend on a natural ventilation system to distribute air.
Solar heaters might not work efficiently when the weather is cloudy, it's raining, or in winter when the sun is not bright enough. Also, the solar panels must face the sun in the right direction to collect maximum sunlight.

It is important to review some terms before calculating the wattage of an electric heater. So, let's dive in.
- Volts (V): It measures the speed of electricity passing through a circuit.
- Amps (A): It measures electrical current, i.e., the number of electrons flowing through an electric circuit.
- Watts (W) and kilowatts (kW): Watts is the electricity consumption rate.
Watt = Volts x Amp
- Kilowatt-hours (kWh): It is the electricity consumed over a period of time.
But how many watts does a space heater use?The electric heaters are available in various wattage ratings. It starts with 200 watts and goes up to 4,000 watts. The average heater used is 1500-1,600 watts. Low-wattage heaters, i.e., 200, 500, and 750 watts, are personal space heaters that you keep next to you to warm your personal space. 1,500 to 4,000-watt heaters can be used for heating rooms and tents while camping.
