How to Choose a 400 Watt Solar Panel

A 400 watt solar panel is the standard residential class in the US, and it fits homeowners, RV and off-grid owners, and small installers. Higher efficiency and larger formats lifted panel wattage, and most home installs now use this class. Efficiency across the class runs 20.5% to 23%.

Homeowners weigh roof space against yearly use. A 400 watt solar panel for RV or cabin power usually means several panels, not a full array. Installers buy by the pallet.

What Counts as a 400 Watt Panel

A 400W solar panel is any panel rated from 395W to 425W. Manufacturers raised the power of the same physical panel from 400W to 415W. A higher-rated model is the same panel in the same format and takes no extra roof space. When you compare listings, read the rating, not the name.

An exact 400W rating is uncommon, since models are rated slightly above or below. A listing on either side still counts, so do not rule it out for missing the round number. Shop the whole class first, then narrow by brand, cell type, and warranty.

N-Type or PERC, Bifacial or All-Black

For a 400W panel, choose N-type TOPCon for slower degradation, PERC for a lower price, bifacial for light-colored roofs, gravel, or ground mounts, and all-black for appearance.

OptionWhy choose it
N-type TOPConIt costs more and degrades more slowly, so it suits buyers who plan to own the system for a long time.
PERCIt costs less and fits a tight budget.
BifacialA 400 watt bifacial solar panel makes sense over a light-colored roof or gravel, or on a ground mount.
All-blackIt is a choice about appearance, so pick it if the array is visible from the street and looks matter to you.

One Panel, a Pallet or a Truckload

A1 SolarStore offers 400 watt solar panels for sale by the single panel, the pallet, or the truckload. There is no minimum order, so one panel is a valid order.

  • Single panel or a few: fits an RV, boat, or cabin.
  • Pallet: fits a small installer.
  • Truckload: fits a larger project.

Price per watt falls as volume rises, so a pallet costs less per watt than a single panel. We carry panels from Q CELLS, Hyundai, Talesun, Trina, REC, Canadian Solar, Mission Solar, JA Solar, ZNShine, Seraphim, Peimar, Axitec, Philadelphia Solar, Phono Solar, and others.

Warranty and Certification

Performance warranties on these panels run 25 to 30 years. The exact term depends on the model, so check each listing before you buy. Compare degradation rates as well as years, since they decide how much output remains at the end of the term.

Look for these marks on the models you compare:

  • UL listing
  • California Energy Commission (CEC) listing
  • Assembled in USA and Domestic Content, for projects where that is a requirement

Confirm the marks against your project's requirements before you order.

FAQ

How much power will a 400 watt solar panel produce?

A 400W panel produces about 1.3 to 1.7 kilowatt-hours a day in real conditions. The rated output is 1,600 to 2,000 watt-hours at four to five peak sun hours, less 15% to 20% for losses. Over a year, that adds up to 480 to 620 kilowatt-hours.

What can a 400 watt solar panel run?

One panel's 1.3 to 1.7 kilowatt-hours a day can run small loads such as LED lights, a laptop, and a fan. It will not run central air conditioning or a whole house, since the average US home needs 17 to 22 of these panels. Pair it with a battery if you want those loads after dark.

How much does a 400 watt solar panel cost?

The 400 watt solar panel price typically runs $125 to $300 per panel, or $0.30 to $0.75 per watt. The current 400 watt solar panel cost on this page starts at $124.56 per panel, or $0.30 per watt. Folding panels cost more, at $270 to $700, because they add a kickstand, a carry case, and cables.

How big is a 400 watt solar panel?

The 400 watt solar panel size works out to about 21 square feet of roof per panel. A 108-cell panel measures 67.8 inches by 44.65 inches by 1.18 inches and weighs 46 to 54 pounds. A 132-cell panel measures 74 inches by 41.1 inches by 1.26 inches and weighs 48.5 pounds.

What is the voltage of a 400 watt solar panel?

A 108-cell panel has an open-circuit voltage (Voc) of 37 to 39 volts, and a 132-cell panel has 45 to 46 volts. Operating voltage (Vmp) runs 31 to 41 volts. It is not a 12-volt panel: its operating voltage is roughly three times that of a 12-volt system.

How many batteries do I need for a 400 watt solar panel?

Plan on one or two 12V 100Ah lithium batteries per panel, since one stores about 1.28kWh and the panel makes 1.3 to 1.7 kilowatt-hours a day. One holds about the low end of that range, and two cover a full day when the sun is good. Check the maker's depth-of-discharge limit.

How long does it take to charge a 100Ah battery with a 400W solar panel?

A 12V 100Ah lithium battery charges in about four hours of good sun. That assumes the panel delivers its real-world output, after 15% to 20% losses. In December, Newark and Austin average about 2.6 to 2.7 peak sun hours, so the same battery takes about one and a half days to fill.

Will a 400 watt solar panel run a refrigerator?

Yes, with a battery, one panel can run an Energy Star refrigerator that uses 1 to 1.5 kilowatt-hours a day. The panel makes 1.3 to 1.7 kilowatt-hours a day, so it covers the refrigerator on a good day. Little is left for other loads, and a low-output day can fall short.
