How Many Solar Panels For 5000 Watts

How Big Are Solar Cells

Lately, manufacturers started to experiment with different individual solar cells sizes in order to reach higher solar panel efficiencies and performance.

Nowadays, the market is dominated by two solar cell sizes:

• 5 W x 5 L
• 6 W x 6 L

The 5 are mostly used by Sun Power in their 96-cells panels, making that panel to look like a common 60-cells one.

How Many Kwh Can Your Solar Panels Produce The Complexities Of Production Ratios

The amount of power your solar energy system can produce depends on how much sunlight exposure your roof receives, which in turn creates your production ratio. The amount of sunlight you get in a year depends on both where you are in the country, and what time of year it is. For instance, California has more sunny days annually than New England. But in either location, youll be able to produce enough power to cover your energy needs and say goodbye to your utility billsif you live in an area that gets less peak sunlight hours, youll just need to have a larger solar array system installed at your home. Thus, production ratios differ according to geographic location and a lower production ratio means youll need more solar panels to get the amount of energy production you need.

Hours To Run The Inverter:

The duration is crucial. Energy supply is calculated based on the number of hours the battery runs. Find out for how many hours you are going to run the inverter.

Is it for a couple of hours, 10 hours or 12 hours, or even more? The watt will be calculated based on the number of hours, and you can decide the battery capacity.

Lets say you have a 5000 Watt, 48V inverter. You plan to run the inverter for the approx 6 hours.

If we consider the power load factor as 0.8, then there are chances that the volt-amperes may value at 130 amperes.

Therefore, your connected battery should generate a minimum of 130 amperes of power.

The challenging part is the 48V 130 amperes are very uncommon, so you may have to adopt the alternatives where you will connect the 200 amperes instead.

How Many Solar Panels Do I Need To Run A 2 Ton Ac

A 2-ton air conditioning unit can cool off 900-1,200 square feet . For AC power consumption calculations, it will take 2,000 Watts of electricity to run a 2-ton AC unit.

Dividing 2,000 Watts by 100 Watts or 300 Watts for our solar panels will result in twenty 100-Watt solar panels or about seven 300-Watt solar panels.

Editors Note: This Is An Overview On How To Understand How Much Energy Your Solar System Will Produce And Overall Solar Panel Output

We always advise speaking with at least a few certified solar installers to understand how all the factors will affect solar panel output for your system.

Solar panels indicate how much power they intend to produce under ideal conditions, otherwise known as the maximum power rating.

But how much electricity your solar panels produce depends on several factors.

• Does intermittent shading obscure direct sunlight from hitting the roof?
• How much sunlight does your roof get on average?
• How big are the solar panels, and how efficient are the solar cells at converting energy?

Because the seasons and weather conditions affect the amount of sunlight hitting your roof, and the amount of sunlight also varies on the time day, you cant use just the solar panel ratings to predict how much power youll get. However, your location will allow you to do some math and determine how well a solar panel works where you are.

A Washing Machine 800w

Washing machines can be energy efficient especially when using solar energy. They are not one of the bigger energy saps on your solar system, but you still need to use them in an efficient manner to make the most of your power. Always put a cold load where possible and only run full loads.Use the washing machine and dryer during the day when there is a lot of energy production from your solar system. This is done best by setting a timer on your machine so it comes on during peak energy-producing periods.

How Many Solar Panels Do I Need To Run A 4 Ton Ac

A 4-ton air conditioning unit can cool off a space thats 2,100-2,400 square feet . For AC power consumption calculations, it will take 4,000 Watts of electricity to run a 4-ton AC unit.

Dividing 4,000 Watts by 100 Watts or 300 Watts for our solar panels will result in forty 100-Watt solar panels or about fourteen 300-Watt solar panels.

Forget Single Solar Panelshow Much Energy Will Your Whole System Produce

Knowing how much energy a single solar panel produces is all well and good, but more importantly, how much solar power can your roof generate? Lets do the math below:

Take our example above, where youre getting an average of five hours of direct sunlight per day and using solar panels rated at 290 W. Lets say you install 30 of those premium solar panels on your roofthat nets you a 8,700 watt, or 8.7 kW solar panel system, near the average system size purchased on the EnergySage Marketplace. Multiply the five direct sunlight hours we estimated above by 8.7 kW, and we get approximately 43.5 kWh of electricity produced per day. And for one final conversion, if we multiply 43.5 by 365 days in a year, we get approximately 15,800 kWh of electricity produced in a full calendar year from a rooftop array of 30 premium, 290 W solar panels. Considering the average electricity use per year in the U.S. is around 10,600 kWh, thats probably more than enough to power your home on solar.

This estimate is likely on the high end for most solar shoppers, and likely because of our estimate for the amount of sunlight the system will get . To learn more about average sun hours, check out our blog here, where we take a look at average sunlight per year by location.

And Finally Lets Do Out The Math

We have our three main assumptions now how do those numbers translate to an estimated number of solar panels for your home? The formula looks like this:

Number of panels = system size / production ratio / panel wattage

Plugging our numbers in from above, we get:

Number of panels = 10,649 kW / 1.3 or 1.6 / 320 W

which gives us between 20 and 25 panels in a solar array, depending on which production ratio we use . 25 panels each at 320 W results in a total system size of 8 kW, which is right around the average for EnergySage shoppers looking for a solar installer. Tada!

Solar Energy Explaining The Basics

Typically, the relevant size of a solar power system is known by its Peak Volume amount. This is the amount of electricity your system is likely to produce on a gloriously sunny day. So, a 5kw system, for example, will produce roughly 5000w at peak sunshine. 1kw equals 1000 watts Got it? Great!

So, if your system was made up of 250w panels you would need 20 x 250w panels in order to collectively generate 5000 watts or 5kw.

So, what can you expect to run with 1kw of power?

Well, believe it or not, 1000w is sufficient to power:

• 60 low energy bulbs
• 2 x 32 plasma screen TVs
• 1 small pool pump, and around
• One half of a small A/C unit

While that seems pretty good, theres a catch I know, there always is!

A 1kw solar system will only give you 1000 watts of power for a few hours a day Remember peak volume? So your 60 low energy bulbs, for example, will only be working for a short period of time.

So how do you overcome these peaks and troughs?

The answerby connecting to the electricity grid. Okay, so it may seem counterintuitive to connect to the very thing youre trying to escape from, but while the grid absorbs any excess energy you dont use in your home it also works in reverse and can be used to top up your electrical needs when youre using more power than your solar panels can output.

The question now ishow many solar panels do you need in order to offset your electricity usage?

The Number Of Cells And Solar Panel Size

As you might already know, the cells are the core of a solar panel.

The number of cells determines the output voltage of the panel, but it will also determine the solar panel size.

The more cells in the panel, the bigger the panel and the higher possible output voltage.

From this principle, intuitively you might sense that the 72-cell panel of the figure above, apart from being bigger, will have a higher voltage than the 60-cell one.

So, the more cells are connected in the panel, the higher the output voltage. But, for the voltage to add up the cell must be connected in series.

This is graphically explained in the figure below.

How Do I Calculate The Right Solar Array Size

To calculate what solar system size you need, you should first know the amount of energy that you need to generate from your solar solar system daily. The other important things are the sun hours in your area, and your roof space.

Monthly energy bills can provide information on the amount of energy that you consume per day, and therefore how much energy you need to generate daily.

For example, if your monthly consumption is 124 kWh in January, then your daily consumption is 4 kWh. This means that the solar system should generate an average of 4 kWh daily. The 4 kWh can also be referred to as the expected daily solar system power output.

You can follow the same process to find the right commercial solar panel system size if you want to invest in solar PV for your business.

Some people may question if the UK is sunny enough for solar panels. The UK has an average of 4 sun hours daily which means you can certainly benefit from having a solar panel system installed.

It is important to be aware that different regions in the UK have different sun hours per day: England has 4.1, Scotland has 3.7, Northern Ireland 3.2 and Wales 3.3. It is therefore important that you consult your local installer for guidance.

Estimate How Many Days Your Solar System Will Be Without Sun

If you don’t know this information off-hand, you can look up the annual average of cloudy days for your area online. This step is crucial in ensuring you’ll have access to your solar energy year-round. A large solar battery bank size will be best utilized in areas with more cloudy days, while a smaller solar battery bank should be sufficient in areas with prevalent sunlight. However, it’s always recommended to size up rather than down.

Can I Store The Energy To Use Later On

Yes, you can store solar energy for later use. Not all energy produced by the 5kw Solar System will be used, especially during peak periods. This is what is called excess or surplus energy. The thought of producing all this wonderful green energy during the day when you are at work and not being able to use it, later on, is not a great reality.

Therefore almost all solar systems are designed to have a way of backing up/saving excess energy which is mainly used in the evenings. Solar power technology manufacturers have recently designed solar batteries that store energy for later use. Although these were very expensive when they first came out, their price is coming down rapidly and will be very affordable by 2020 onwards.

The 5kw Solar System uses its batteries to save energy by converting from DC to AC. How much energy is stored is dependent on the size of the battery. The bigger the size, the more energy will be stored. The size is determined by the amount of power you need to use around the house and the number of days.

Solar batteries in the solar system store the excess energy as opposed to returning it to the grid. When the panels produce excess power, it is used to charge the batteries. Energy is returned to the grid once the batteries are fully charged.

These batteries are best used at night when the solar panels are inactive. These solar batteries are an effective backup and can provide energy throughout the home when the sun isnt shining.

How Many Solar Panels Do You Need For Common Household Items

If you are considering solar energy for your home, you may also be asking how many panels are needed to power specific appliances. However, it is important to understand how solar generation works:

• Solar systems deliver most of their energy production in the hours around noon
• During the early morning and late in the afternoon, solar generation is much lower. This is because there is less sunlight reaching the panels
• Households have the highest energy consumption in the evening and early morning

Since solar panels depend on sunlight, you cannot control their electricity production. Powering home appliances directly with panels is impractical and potentially dangerous, unless you use a solar battery to store energy. If you connect home appliances directly to the panels and inverter, a dark cloud passing over your home will shut off the power. At night, you would have to switch to the local power supply anyway.

The most practical solution is synchronizing solar systems with the local power supply, which lets them operate as a single power source. When solar generation cannot power your home appliances by itself, the rest of the energy comes from the grid. If your panels have surplus production, you can send it to grid to get a credit on the next electricity bill.

This table considers the most power-hungry appliances found in homes. Most small appliances and electronic devices have a very low consumption, which does not even match the production of one panel.

Determining The Number Of Solar Panels For 1

There are a few things we want you to be must familiar with, so you could assimilate the substantial part. For better depiction, we have subjected 1-ton AC for our calculations. Those are enumerated below

• 1-ton AC consumes between around 1000W and 1333W, depends on which star AC you are using.
• A 6kW system means not it will produce 6000kW yearly. Production varies from region to region predominately due to geography and type of equipment.
• An impeccably placed 6kW system can produce 7000kW+ or in Massachusetts yearly will produce 9000kW+ in California as it gets more sunshine falling on it.
