Understanding a 190 Watt Solar Panel

A 190-watt solar panel is a unit that turns sunlight into electricity. It’s not too big or too small, with typical measurements of about 30 inches by 60 inches. This size makes it a good fit for the roof of an RV or camper van.

These panels can send out around 9 to 13 amps when they’re getting full sun. The power they capture goes through charge controllers, which regulate how much energy flows into batteries.

Solar modules at this wattage are created to work well with both AGM and lithium batteries. They come handy in keeping your battery charged up throughout the day. Depending on the light and how you set them up, their output might change.

When laid flat, they make less power compared to being angled toward the sun’s rays directly.

Charge controllers are essential partners for these solar panels; they prevent overcharging and ensure efficient battery charging. You’ll find two main types: pulse width modulation (PWM) and maximum power point tracking (MPPT).

MPPT versions are typically better because they help get more power from your solar cells even during cloudy days or when your setup isn’t perfect.

What Can a 190-Watt Solar Panel Run?

Embarking on the solar journey with a 190-watt panel unlocks a world of possibilities, enabling you to power essential gadgets and comforts while on the move or living off-grid.

Lights, water pump, furnace fan

A 190 watt solar panel powers essential items in motorhomes and campers. It can keep your lights on, run the water pump, and spin the furnace fan at night. RV expert Dave Solberg says that with a battery, even a residential fridge can get energy from this panel.

If you have three 190 watt panels, they give out about 29 amp-hours (ah) for charging. This means you won’t always need to rely on hookups or generators.

Some users hook up their 190 watt panel to AGM batteries using a solar charge controller. They find it gives them enough power for their lights and water pump each day. They may also turn on their furnace fan for a bit when it gets cold.

Next up, let’s see how small appliances like food dehydrators and electric heaters work with this setup.

Small appliances like food dehydrator, electric heater

You can use a 190 watt solar panel to run small appliances. For example, if you like making your own dried fruits or jerky, hook up a food dehydrator to this panel. It’s perfect for preserving your favorite snacks using solar energy.

Even on chilly days, connect an electric heater to stay warm without adding to your electric bill. These panels are great for reducing costs and using clean power from the sun.

Running these devices with a 190 watt panel is simple with the right setup. You will need a solar charge controller to manage the energy flow and protect your batteries. Pair that with power inverters, and you can convert the stored solar energy into usable electricity for any small appliance you have at home—whether it’s keeping food fresh or staying cozy when it gets cold outside.

Comparing 190 Watt to 300 Watt Solar Panels: Efficiency and Applications

Solar panels with different wattage ratings offer varying levels of efficiency and are suited for diverse applications. A 190-watt panel contrasts a 300-watt panel significantly in terms of output and the scale of use cases they can handle.

  • 190-watt panels typically yield less electricity, making them more suitable for smaller, less power-intensive applications.
  • In contrast, 300-watt solar panels produce more energy, ideal for running larger devices and supporting more robust systems.
  • The 190-watt panel is often preferred for charging small electronics, powering LED lights, or maintaining a charge for smaller battery systems.
  • 300-watt panels, on the other hand, can handle the energy demands of larger appliances, such as refrigerators or small air conditioning units, when used in multiples.
  • Applications for 190-watt panels include remote surveillance systems, small water pumping stations, or portable power for camping trips.
  • Bigger setups like residential solar power systems or off-grid cabins are better served by the higher output of 300-watt panels.
  • Energy efficiency is crucial; 190-watt panels have a smaller footprint but may require more space to match the power output of fewer 300-watt panels.
  • For an RV, a 190-watt panel might suffice for basic electricity needs, while a 300-watt panel could provide a comfortable surplus, reducing the reliance on generators or shore power.
  • Financial investment is another consideration; 190-watt panels may be more affordable upfront, but 300-watt panels might offer better long-term value due to more significant energy production.
  • The choice between 190 and 300-watt panels ultimately hinges on the specific energy requirements, available space for installation, and budget constraints of the user.

Efficiency of a 190 Watt Solar Panel

A 190-watt solar panel from Go Power! uses high-efficiency monocrystalline cells. These cells do a great job of turning sunlight into electricity. This type of panel works well even in smaller spaces because it makes lots of power without being big.

It can charge batteries better because it’s good at picking up solar energy.

Inverters are key to making sure you get the most out of your panels. You need the right size inverter to make your system work best. If you mix panels with different watts, you might not get as much power.

That’s because they have different voltages and amps that may not match well together. Always pick an inverter that fits your setup to keep things running smoothly and efficiently.


A 190-watt solar panel keeps RV batteries full. It powers lights, water pumps, and furnace fans at night. Small appliances like food dehydrators and electric heaters also work with this panel.

With premium cells and MPPT controllers, it makes energy use efficient. This solar power fits many needs without taking up much space.


Can a 190-watt solar panel charge my phone?

Yes, a 190-watt solar panel with high-efficiency solar cells can easily charge your phone and other small electronics.

Will a 190-watt panel work for a small solar array in different climates?

Absolutely! A single 190-watt panel can be part of a larger solar array, and it’s designed to perform well in various climate conditions.

Do I need special equipment to use a 190-watt solar panel?

To safely use the power from your 190-watt solar panel, you’ll need items like solar charge controllers to manage the energy flow.
