Wondering how much power or electricity will a 3kW solar panel produce? So you my friend have come to the right place.

This is going to be a thorough guide on how much DC and AC power output you can expect from a 3kW solar system according to your location.

Also, I'm gonna share some tips on how you can get the maximum output from your solar panels.

** Need a simple solution?** Use my free online solar panel output calculator to find out the power output of your solar system. Or use the chart below to find out the estimated output

## How Much Power Does a 3kW Solar System Produce?

**3kW solar system will produce about 12kWh of electricity or power per day, 360kWh per month, or 4,380kWh per year. Considering 5 hours of average peak sunlight per day.**

Now let's discuss how many hours of peak sunlight your location receives and how to calculate.

## How To Calculate Peak Sun Hours?

Only under standard conditions, solar panels will produce their rated wattage output.. which includes, **1kW/meter ^{2} of sunlight intensity, 25^{o}C temperature, no wind, and direct tilt angle.**

That is why we consider peak sun hours as the baseline when estimating the solar system output.

The intensity of the sunlight will be different throughout the day like for example.

**Noon:**1000 watt/meter^{2}sunlight intensity (1 peak sun hour)**late evening:**200 watt/meter^{2}sunlight intensity (0.2 peak sun hour)

To find out the total number of peak sun hours your location receives using this **calculator**.

### Step 1: Enter Your Address

### Step 2: Click Results

After selecting the result session you'll be able to see the number of peak sun hours per day, month by month.

These are the result from **Florida city** where i live. As you can see the average number of peak sun hours is about 5.87 or 5.87kWh/meter^{2 }of solar radiations per day.

## Average Solar Panel Output

you have a 3kw solar system so it should produce 3kWh in 1 peak sun hour? well, not exactly.

Yes, sometimes you'll receive 3kW of power output from your solar system but it will last for a few minutes.

Some days you may get more power output and some days it'll be lower. This will totally depend on the weather conditions.

and also there will be some power losses in DC cables and in charge controller.

Speaking from experience. on average, i receive about **70-80%** output from my 400-watt solar panels per peak sun hour. This conclusion is based on 30 days of output data.

## DC vs AC Output

All the numbers which i have talked about above are DC output (Direct current).

Solar panels produce power in DC and also batteries store power in DC, in simple words lower voltage.

but most of our household appliances required AC (alternating current). so to convert DC into AC we use an inverter.

As nothing is perfect when it comes to solar power or electricity in general. Solar power inverters are not 100% efficient.

This means there will be some percent power loss when converting DC into AC. Most solar panels are about **90% efficient**.

This means a **10% of power loss** will occur when converting DC - AC.

## How To Calculate Power Output Of The Solar System?

Here are simple steps to calculate the power output from your solar system.

i would take a 3kW solar system and my city as an example (Florida city). Which receives on average 5.8 hours of peak sunlight per day.

`5.8 * 3000 = 17,400Wh`

Now multiply the value by 0.8 to subtract the power losses.

`17,400 * 0.8 = 13,920Wh (DC) `

Now let's convert the DC watt into AC, considering a 90% efficient inverter.

`13,920 * 0.9 = 12,520Wh (AC)`

in Florida, on average you'd receive about **14kWh DC** and **12.5kWh AC** power output from a 3kW solar system per day.

## How To Get The Maximum Output From Your Solar System?

Before getting into how you can maximize the output performance of your solar panels. first of all, let’s discuss what factors affect the power output.

As i have discussed earlier. Only under specific conditions, a solar panel will produce their rated power output.

Other than those conditions there are some other factors that will affect the output.

Which includes...

**Dirt or dust on the solar panels****DC cable losses****Charge controller inefficiency****Tilt angle**

Which in the real world is rarely gonna happen. but we can do some steps to make sure that we’re getting the most from our solar system.

Here are some things which you can do to increase the output from your solar system.

**Clean your solar panels from time to time****Use the right size DC cables****Keep the shorter distance between solar panels, the charge controller, and the batteries****Install your solar panels at a right tilt angle**(use this**calculator**to find out)**Use an MPPT charge controller**

**Watch this video to check the effect of tilt angle on solar panels output. **
