Kw Solar System Pricing

1kW Solar Panel System | 1 kW Solar Panel Price & Working 2021 | Solar System for Home |

A 1000kW solar system will certainly cost a different amount depending on the solar business you buy it from. Prices also vary from city to city due to logistics, taxes etc. To give you some indication though, we believe that the “market price” for a 1000kW solar system at the moment is between:$1,150,000.00 to…$1,750,000.00 .

NOTE: The Prices above are “after-rebate” prices and are only a guide to what you might expect as at November, 2015.

How Much Does a 1000kW System Cost?

The cost of 1000kW solar power systems varies. On the lower end, you might expect to get Chinese inverters such as Sungrow, Growatt, JFY, Samil etc. and Chinese panels such as Hannover, Munsterland, ZN Shine etc. You might expect to pay $1,150,000.00 for such a system.

On the higher end of the spectrum you might be looking at a premium, European inverter like SMA, ABB, Fronius etc. and a tier 1 panel like SUNPOWER, TRINA, WINAICO etc. You might expect to pay $1,750,000.00 for this type of 1000kW solar power system.

Finance Repayments on a 1000kW Solar Power System

You could expect to pay somewhere between $35,239.46 and $53,618.77 per month as a repayment for your 1000kW solar power system.Note: This figure could vary drastically. It is based on some common solar power finance rates for residential size systems.

Whats The Payback And Savings

Generating about 3,000 kWh from solar panels instead of from a gas-fired power station will save about 1.2 tonnes of carbon dioxide emissions. The energy used during the manufacture of PV panels is far less than they will generate through their lifetime. Even with the average UK levels of sunshine, a PV array will pay back this embodied energy in less than three years. See the related questions below for more on the environmental impacts.

You can now get payments back under the Smart Export Guarantee scheme. You can claim for the PV-generated electricity that you export to the grid rather than using directly in your house. Therefore, to claim SEG payments you need a type of smart meter thats able to measure exported electricity . The previous feed-in tariff scheme closed to new PV installations in April 2019.

You should shop around and compare the prices offered for your exported electricity. Bear in mind that you can sign up for SEG payments with a different company to the one you buy electricity from. Some companies may offer a decent SEG price of over 5 pence per kWh, but some might pay 1p per kWh or less. Solar Energy UK have compiled a league table of tariffs. They say a fair price is between 5 and 6 pence per kWh. That sort of price is comparable to the wholesale market rates that large generators get for selling electricity. Please note that these prices are from before the current upheaval in the electricity markets, which will undoubtedly change things.

How Many Solar Panels Are Required For 1kw

How many solar panels do I need to install in 1KW solar system? The quantity of solar panel depends upon their capacity and size. In a 1 KW solar system, if you are using a 250 watt solar panel then 4 panels are required, and simultaneously if you are using a 335 watt solar panel then 3 panels are enough for it.

How Is A String Inverter Different From A Micro Inverter

There are different types of solar systems. The inverter is the device that converts the DC electricity generated by a solar panel into AC electricity, which is what you use in your home.

A solar energy system with a string inverter consists of a series of interconnected solar panels linked to a single converter. The inverter then converts the electricity supplied by all the panels from DC to AC.


  • only one inverter which can fail
  • cheaper than multiple micro inverters

In a system that uses micro inverters. Each solar panel is fitted with a micro inverter that converts the electricity from DC to AC.


  • optimisation of each solar panel output
  • micro inverters typically come with a 25-year warranty

How Many Solar Panels Do I Need Then

Related:How many solar panels do I need?

Typically, a modern solar panel produces between 250 to 270 watts of peak power in controlled conditions. This is called the nameplate rating, and solar panel wattage varies based on the size and efficiency of your panel. There are plenty of solar calculators, and the brand of solar system you choose probably offers one. That said, there is a simple equation to calculate the amount of kilowatt-hours your solar panel system will produce.

So now that we know you need to produce about 6kW of AC output, we can work backwards to figure out how many solar panels you need. Solar panels produce direct current , and your home runs on alternating current .

Yep, like the band, AC/DC.

Because of physics, there are losses in converting the energy from the sun into DC power, and turning the DC power into AC power. This ratio of AC to DC is called the derate factor, and is typically about .8. This means you convert about 80% of the DC power into AC power.

This continues to improve ever so slightly, but the losses are unavoidable because of physics! So you take the AC amount you need: 6kW and divide by .8 . This means that youll need 30 250Wp solar panels or 27-28 270Wp panels.

So How Many Solar Panels Do You Really Need To Get 1000 Kwh Per Month

If your goal is to produce 1,000 kWh per month, then truly you must produce 1,250 kWh per month to allow for loss in output efficiency.

Remember, if you are receiving an average of four hours of usable sunshine per day and your solar panel is rated at 250 watts of power, then you will need forty panels to reliably generate 1,000 kWh per month.

An average residential solar panel size today is about five and a half feet by three feet.

But the number of panels and consequent space needed can vary depending upon whether you select lower-efficiency economy panels or high-efficiency premium panels.

Consider this table when trying to figure out how many solar panels you can put on your roof:

So go out and take a look at your roof and consider the sunlight falling on it. Think about the size and placement of solar panels. Do a cost analysis of the savings you will experience from creating your own clean, renewable energy.

How Do I Check That My Solar Panels Are Working Efficiently

Your solar panels are connected to a control panel called an in-home display. This is a wireless device you can use to monitor whether your system is generating as much electricity as it should be.

If youre concerned that your solar panels are underperforming, contact the installer or manufacturer. They can send out a professional technician to investigate.

We dont recommend ever tampering with the solar panels, as this can damage the system and invalidate your warranty.

How Much Do I Save

How Much Power Does A 5kW Solar System Produce?

Finally, lets find out how much you can save per month on average from your monthly electric bill!

Lets plug it all in:

On average, your solar system is going to lose some energy due to wiring, power, inverter efficiency, so you actually end up using 80% of your solar systems capacity.

To figure out how many kilowatt-hours your solar panel system puts out per year, you need to multiply the size of your system in kW DC times the .8 derate factor times the number of hours of sun. So if you have a 7.5 kW DC system working an average of 5 hours per day, 365 days a year, itll result in 10,950 kWh in a year.

If you divide your expected 10,950 kWh of annual production by 12, youll see that your system will offset about 912 kWh per month from your monthly electric bill, which can translate to $100 or more per month depending on how much you pay per kWh!

So to break this down into simple math that you can do:

AC rating = Average kWh per month / 30 days / average sun hours per day

example: 903 kWh per month / 30 days / 5 hours = 6.02 kW AC

DC rating = AC rating / derate factor

example: 6.02 kW AC / .8 = 7.53 kW DC

Number of panels = DC rating / Panel Rating *note this is important b/c panels are rated in watts, and the systems are rated in kilowatts . So a 7.53 kW system = 7530 Watts and a 250 watt panel = .250 kW

example: 7.53 kW x 1000 / 250 watt = 30.12 panels, so roughly 30 250 panels

Annual Solar Inspections: $200$400+ Per Year

How much your solar inspection is going to cost depends entirely on how large your system is and who performs your inspection.

An annual inspection is the best way to determine that your solar system is still operating at maximum efficiency based on its age and whether any work needs to be carried out to bring it back up to an optimal standard.

This can seem like an unnecessary expense, but it is well worth paying for if it guarantees the future longevity of your system and the savings that come with it.

Reduction In Energy Costs

Youll save between $650 to $1,500 annually. Over a 25-year period, youll save between $15,000 to $40,000 in energy costs. Cost ranges vary by regional differences in the cost of electricity and how much sun youll get. Dont expect to save as much in a darker northern climate as you would in southern California, Florida or Hawaii.

A great first step in determining which products are right for your home is to conduct a Home Energy Audit. A home auditor will do a detailed inspection of your usage and areas where you can improve to help you determine if you would benefit from a solar system. From there, a pro can help you to select the right location, size, mounts, and panels to maximize on savings.

Although you may hesitate to spend the money on the most expensive types of panels and mounts, it is good to remember that you will save money on the other side with decreased electricity bills. It could be that what you spend up front will pay for itself very quickly in your reduced monthly bills.

You can enhance your savings by selecting products with higher efficiencies and investing in track mounting. Track mounting will ensure that your system absorbs all the light it can, and high-quality panels will be able to capture and convert that light at a greater rate.

Solar Panels Needed For 1000kwh

If you live in California, chances are you are going to need sixteen 400W solar panels in order to offset your 1000kWh electricity consumption each month.

Now of course this will change depending on where you live and what type of solar panel you use.

For example, lets take the exact same scenario for someone living in London.

1,000kWh ÷ 86,8 = 11,52 x 1000 = 11,520.

11,520 ÷ 400W = 28,8

As you can see a home located in London using the exact same amount of electricity as someone in California will need 29 solar panels instead of 16 in order to offset their consumption.

Peak sun hours plays a major roll in establishing how many solar panels you will need .

So if someone goes ahead and tells you, you will need 20 solar panels for 1,000kWh They are wrong. It all depends on where you live and what power rating your solar panels will be.

A house roof is usually an excellent site, but solar panels can also be mounted at ground level. You need a site thats largely free of shade, particularly between spring and autumn. Solar panels perform well if facing anywhere between south-east and south-west, at an angle of 20 to 50 degrees. A PV array that faces due east or west will give about 20% less energy than one facing due south. Roof mounted panels are usually a permitted development, so you wont normally need planning permission.

How Much Do Solar Panels Cost To Lease Should I Buy Or Lease Solar Panels

Buying solar panels will always be far more advantageous than leasing them for a wide number of reasons.

  • Solar leases and loans have built-in escalation clauses that mean you will be paying significantly more over time to use your panels than you would if you purchased them outright.
  • You will never own the panels if you lease them unless you pay a hefty balloon payment at the end of your solar agreement.
  • Solar leasing can prove to be problematic for those who wish to move and can lead to additional costs being incurred. Your home value may also be negatively affected.

The only benefit of leasing is that you do not have to pay for the installation of your solar panels yourself. Compared to buying though, you are simply not going to see the same level of savings through leasing. We have covered this topic in comprehensive detail in one of our other posts if you would like to take an in-depth look at this subject.
