How Much Energy Will A 400

While most homeowners will naturally want to know how much energy each 400-watt solar panel they install on their homes will produce, the answer is a bit complicated.

The rating on your PV module in wattage tells you the maximum amount of energy it can generate with full, intense sunlight. This measurement of power output is called the Standard Test Condition .

However, in reality, there are many factors that affect the panels efficiency and power production. Some of the factors that affect your production are shown below:

• The intensity of the sunlight that hits the panels
• The hours of daylight in your area
• The weather, including the average number of cloudy days per year
• Shading on your property from trees or nearby buildings
• The brand of the panel you choose and its maximum efficiency
• The age of your panel, as they lose efficiency over time

For a baseline production, you can use the calculation belows, but remember that this estimate can change drastically based on the factors above:

Your Daily Watt-Hours per Panel = x x

Your Daily Kilowatt-Hours per Panel = / 1,000

If we assume that your area receives eight hours of sunlight every day, we can use the above equation to calculate how much power each 400-watt panel on your property will produce on a daily basis.

x x 75% = 2,400 watts per day

/ 1,000 = 2.4 kWh per day

/ = 12.23 panels, which gets rounded up to 13 panels

What Size Charge Controller For 400

The job of a charge controller is to adjust the voltage output from the solar panels according to the battery voltage.

Depending on the sunlight intensity the voltage of your solar panels output will change accordingly.

e.g at the standard sunlight conditions you can expect 18-20 voltage output from your 12v solar panel system so the charge controller will lower the voltage to match the voltage of your battery.

use this formula to calculate the size of the charge controller according to your solar panel size

Dividing the solar panels capacity by battery voltage will give the number of Amps that a charge controller will have to handle. And the extra 25% is added for safety reasons

For example, if youre going with a 12v system.

400/12 = 33, 33 + 25%  = 41 Amps

youll need a 40A charge controller with 400W solar panels to charge your 12v battery.

Chart What Size Of Cable Should I Use With My Inverter

Calculate the amount of current produced by the solar panels and then how much current youll pull from the battery with the help of an inverter

The maximum watts youll get from your solar panels will be 400 watts

Amps  = watts/voltage  

400/12 = 33.3 Amps

For a 12v 400W solar system, youll need a 6 AWG size wire to connect the solar panels with the charge controller and from the charge controller to the battery

And with the help of chart 2 select the size of the cable to power your inverter from the battery bank

Tinned Copper Lugs Check Price

Tinned copper lugs will be used as a connecter from the charge controller to the battery and from the battery bank to the charge controller.

Length Of Manufacturers Warranty

Take notice of the warranties that the vendor offers.

If the vendor is trustworthy and the panels have a lengthy warranty duration , you should expect the solar device to last a long time, long enough to compensate for itself and generate a profit.

However, for the warranty to be honored, the seller must always be in business. As a result, be wary of labels that dont have a proven track record.

How Big Is A 400 Watt Solar Panel Dimensions

What size is a 400 watt solar panel?

The exact size of a 400 watt solar panel is determined by how many solar cells are used in its production. Most panels are somewhere between 40mm and 55mm thick, and can weigh 20kg to 25kg.

A common surface area is 2050mm x 1050mm and the thickness varies across manufacturers. The solar cells are all about the same thickness across the board but the extra layers of EVA plastic, solar panel backing and the glass cover thickness varies, but not a lot.

Best 400w Solar Panels: Warranties

Solar panels are expensive, so its important to protect your investment by choosing a solar panel brand that provides a lengthy warranty.

Solar warranties can cover the equipment, the labor or workmanship for the installation, the power production over time or a combination of the three. Longer warranties that cover all aspects of your solar project are, of course, the best option. Panels sold for DIY solar installation will not include a workmanship warranty.

How Much Power Does A 400

On average you can expect 1600-2600 Wh or 260-320 watts out per hour from your 400W solar panel. The difference will depend on the weather conditions & solar panel tilt angle. Under ideal conditions, you can expect 400 watts of power per hour from your solar panel but it will rarely happen

These numbers are the average output power which you can expect, some hours you may receive 400 watts of power and in some hours you may receive 200 watts of power

The power output from your solar panel will highly depend on the weather conditions, your geographical location, and how many hours of peak sunlight you receive.

I have covered this topic on power output from 400W solar panels in very detail & also how many hours of sunlight your state receives or any geographic location in the world you are from.

How Many Amps Does A 400 Watt Solar Panel Produce

The electrical specifications for a typical 400 watt solar panel might be:

• Max Power at STC: 400W
• Max System Voltage: 1000VDC
• Optimum Operating Voltage : 72.9V
• Open Circuit Voltage : 85.3V
• Optimum Operating Current : 5.49A
• Short-Circuit Current : 5.74A

The electrical specifications provide a lot of valuable information, but we need to be sure of what the different numbers mean.

For this 400 watt panel the maximum working current is 5.29 amps, and this happens when panel voltage is 72.9 volts .

How much current does a 400 watt solar panel produce?

The values of voltage and current that generate maximum power are optimum at the Maximum Power Point . This is how the panel rating is calculated multiply 72.9 volts x 5.49 amps you get 400 watts.

If you happen to have 400 watt panel that has no label, then multiply Isc by 96% and that will be the maximum current the panel can generate.

You just short the leads through a multi-meter on the ammeter setting to find Isc. Multiply this number by 96% to find the maximum working current in full sunshine.

Watt Solar Panel Wiring Diagrams

Theres a few points worth clarifying about these wiring diagrams before you get into the detail:

• The wiring diagrams shows only the supply side installation of a 400 watt solar panel system. They goes as far as charging the battery. For the load side detail, check out our post on campervan wiring.
• They exclude charging the battery from shore power or the alternator.
• This set up needs a minimum of 150 180ah of battery so the diagrams have 2 x 12v batteries wired in parallel.
• For more information on how to fit the batteries or to wire them in series if using 6v batteries, see our post on campervan batteries.
• The diagrams also excludes wiring an inverter it sits on the load side of the battery.
• The 4 diagrams below show a 400 watt solar panel wiring diagram wired in parallel and series with 2 x 200w and 4 x100w panel configurations.
• For a full breakdown of the detail, comparisons and even an interactive calculator for mixed panels, check out our complete guide to wiring your solar panels in series or parallel.
