Can You Run a Tankless Water Heater on Solar? Discover the Possibilities!

Understanding Tankless Water Heaters

Yes, you can run a tankless water heater on solar power. You would need a solar panel system that is capable of generating enough electricity to power the unit. This is a more sustainable and energy-efficient method of heating water, but the initial setup can be costly.

Let’s begin at the foundation – what is a tankless water heater? Essentially, it’s an on-demand, high-efficiency water heater that doesn’t use a storage tank. Instead, it heats water directly as it flows through the device. This approach eliminates the heat loss often associated with storage tank heaters.

The cost of a tankless water heater itself is higher than traditional ones, yes. But, the longevity and efficiency of these systems make them worth every penny in the long run.

The required system size and the heater’s output are calculated by gallons per minute (GPM). It’s crucial to get the correct size for your home to ensure peak performance and to avoid unnecessary costs.

As for the pros, expect vital energy savings, an endless supply of hot water, and a more extended lifespan compared to traditional heaters. On the downside, that steep upfront cost might inspire a gulp or two. But, I assure you, with 20 years of experience in solar energy under my belt, it’s worth it!

Solar Power and Its Connection with Tankless Water heaters

Solar Power and Its Connection with Tankless Water heaters

If you’ve ever wondered, “Can you run a tankless water heater on solar?” – the answer is yes, and more efficiently so.

Most folks fret about the lack of sun at night. Not to worry. Solar energy can be stored efficiently using modern batteries for nighttime or cloudy day use.

Tankless water heaters are excellent companions with solar power. By eliminating the standby heat loss that happens with standard heaters, you’ll already be scoring points on the efficiency front, before even bringing solar into the equation. Now, mix that with sun-derived power and voila! You’re amplifying energy savings by an impressive fold.

And let’s not forget the environmental impact. Using solar power to warm your water will cut down your CO2 emissions, contributing significantly to Mother Earth’s wellbeing.

How Many Solar Panels Do You Need For a Tankless Water Heater?

Many readers often ask me, “How many solar panels do I need for a tankless water heater?” There isn’t a one-size-fits-all response. Your requirements depend on the size of the heater and local sunlight conditions, among other factors.

A typical home-grade solar panel produces around 265 watts of power in an hour of direct sunlight. A small tankless water heater typically requires about 12,000 watts (12kW). So, a simple calculation would suggest you need about 45 panels. But these are rough estimates, and actual numbers can vary with solar panel efficiency, geographical location, and daily usage.

Pair tankless water heaters with solar power, and you get a blissful marriage of energy efficiency and an unlimited hot water supply. You can quickly usher in hot showers even during cold winter evenings with the energy stored from solar panels. How cool—or should I say warm—is that?

Being tankless, these heaters deploy a space-saving design, allowing for easy installation in tight niches around your home.

Finally, the long lifespan associated with both tankless heaters and solar panels provides a great return on investment. Not only will you see savings on monthly utility bills, but also these systems tend to outlast their conventional counterparts, offering true bang for your buck.
