What Can You Run Off A 400 Watt Solar System

Mounting Location On My Fifth Wheel Roof

DIY 400 Watt 12 volt Solar Power System Beginner Tutorial: Great for RV’s and Vans! *Part 1*

When I laid down the original 100-watt panels I did so with a future expansion to 4 panels in mind. I had envisioned mounting four 100 watt panels at the very front of the fifth wheel. Here my reasons for this decision:

  • Shadows on the panels would not be an issue
  • There was the perfect amount of space to mount the four panels sideways
  • They would be slightly tilted to capture more sun
  • The tilt would allow rain to run off
  • Its the closest location to the batteries
  • It looks really cool!

How Much Energy Does A 400

Solar panels rated at 400 watts can give you a maximum of 400 Watts of electricity per hour.

But the exact amount of power you can generate will depend on the following factors:

  • The number of peak sun hours in your location
  • The existing weather conditions of your state
  • Presence of dirt, dust, and or bird droppings on your panels

So, if you live in South Carolina, where the peak sun hours is 5, then your 400-watt solar panel can potentially generate a total of 400 W * 5 hours = 2,000 wh of energy within a day.

On average though, 400w solar panels give about 1.6 kWh of energy a day in the US.

Watt Solar Kits With Solar Power Generators

If you havent already purchased your solar panels, there are complete kits available that include everything you need to produce and use the solar power you’re harnessing. The Inergy Apex Gold Kit is an extremely powerful 500 watt solar panel system that is backed by an easy-to-use, portable solar power generator. If youre looking for something even more powerful, there is the 500 Watt Solar Kit with the Titan, which has a larger inverter and room for added solar input or storage.

If you already have solar panels, or would like to build a custom solar generator kit, there are plenty of medium and large sized solar generators that can handle 500 watts of input such as The Bluetti. A large advantage of using a solar generator is that it can be temporarily detached from the panels to power something in a different location. Solar generators are also all-in-one solutions that you can just plugin and power up. For more information on solar generators, read our solar generator buying guide.

Will A 400 Watt Solar Panel Run A Refrigerator

A 400 watt solar panel will run a fridge

A 400 watt rated panel will run a medium size refrigerator, combined with a 120Ah lithium iron phosphate battery and a 500 to 600 watt inverter . If a 400 watt solar panel produces about 584kWh/year and a refrigerator needs between 2ookWh to 400kWh/year, then it seems a comfortable match.

Lets take a closer look assume the fridge in question consumes 400kWh/year.

A fridge runs continuously day an night, but solar panels only produce power during the day. This means some kind of battery is needed to power the refrigerator during the night equivalent to about 200kWh/year or 50% of the energ needed.

In daylight hours the solar panel has to generate 200kWh per year to power the refrigerator and an additional 200kWh to charge the battery back up for running during the night.

If there are not too many cloudy days a 400 watt panel should generate enough energy to run a medium sized fridge.

Our First Rv Solar Experience

About a year ago I popped my RV solar cherry and installed a simple little 200 watt RV solar kit from a company called Renogy. We didnt have too much dough to spend on solar, but I believe I got a good bang for the buck with the roughly $400 dollar kit. Renogy panels seem to get very good reviews and after a year of use Ill add to that with a full thumbs up. They are light weight but sturdy and put out decent amounts of power.

With the 200-watt starter kit, we were able to keep all our smaller electronic devices, camera batteries and 2 laptops all charged up plus top up our 2 six-volt golf cart coach batteries for the evening hours. We spent many weeks out boondocking where we never had to run the generator. As long as we stayed conservative with our energy use and the sun shone most of the day we could enjoy the peaceful atmosphere.

What Quantity Of 400

An individual 400W solar panel is rated to generate 400 watts of power, but the actual power output you see from your panels depends on many parts, including geographic location, shading, and the tilt of your panels.

The quantity of solar panels youll install depends on the amount of electricity you want to produce and the space available for solar panels. The table below compares different sized solar panel systems by the number of 400W solar panels required for each system size. In some cases, the number of 400W panels is curved to the nearest panel.

What Quantity Of Panels Would Be Needed For 3,000 KW Hours?

Using five 400W solar panels will generate roughly 3,000 kilowatts hours of electricity, which is significantly below how much power a standard single-family household uses. Installing 15 panels for an approximately 6 kW system will produce enough electricity to offset or eliminate your electric bill with solar substantially. Solar is going to make a lot of energy and for a low price.

How much area will a solar energy system using 400W panels take on your roof or property? The following information demonstrates estimates for solar energy systems using only 400W solar panels. To calculate estimated space needed, we assumed that 400W solar panels are, on average, 22.75 square feet .

What Is Causing My 400

As a result of your calculations, this Solar Panel can produce up to 26 amps per hour.

On the other hand, when you look at the statistics, you find that the amps are much lower in the low 20s.

What exactly is the problem? Here are a few possible explanations for why the Solar Panel isn’t generating sufficient amps:

  • Cloudy skies: Even though there is no rain, passing clouds that obscure the sun’s rays will have an impact on the solar panels.

    Even if it is only for a brief period, you will notice a decrease in the charge rate.

  • Shading: The solar cells are extremely sensitive to any form of shade they may be exposed to.

    Even a small amount of foliage, dirt or other debris might have an impact on the production.

    Solar panels must be cleaned regularly to prevent dirt from accumulating.

  • Charge controller with pulse width modulation : As previously stated, a PWM controller is restricted to 14.4V, while an MPPT controller can operate a 400W Solar Panel at full capacity.

  • Low Solar Panel efficiency is a problem: For the solar system of this scale, an efficiency rate of below 20% is insufficient to meet the requirements.

    The higher the efficiency of the solar panel, the greater the amount of electricity the system can generate.

There is nothing problematic with your Solar Panels at this time.

The output of 26.6 amps is just the most that is attainable with this configuration.

The current may drop to the low 20s from 26.6 amps.

As the wattage decreases, the amps decrease as well.

Pair It Up With A Battery

400 Watt Solar Panels

Almost all of the solar panels that you buy will be needing a battery bank for all of that power to be stored into as well, unless if you bought a solar panel kit- in that case, the kit will include a battery inside of it, but dont let it stop you from buying a bigger battery bank that will store more power to be used.

Usually, RV owners will buy two batteries, just in case, depending on their budget- the more, the merrier! For a battery, youll also need other appliances like inverter chargers, charge controllers, and battery monitors.

Inverter chargers are inverters that convert sunlight power which is usually wild, lingering electricity that doesnt like to sit still inside of battery banks and want to be used up immediately into usable, DC power which is power that can be stored inside of battery banks to be used later.

Charge controllers are cheap devices that prevent too much power from being used- if youre going to be using a lot of power at once or connecting a lot of devices up to one battery, youll need a charge controller to prevent your solar panels or battery from overheating and being damaged.

Battery monitors are just what they sound like- theyre monitors that you can buy in order to display the amount of battery power left inside of the battery. Theyre very cheap and a good-to-have kind of item if youre a careful planner like me.
