50KW produces £15K instead of £29k yearly

[warksfarmer]

50KW systems installed around 2011 will receive around 40.8 Pence per KWH Feed-in-tariff in generation tariff. We ignore EXPORT tariff for simplicity sake.

A 250 Watt panel gets 4 hours on sunlight daily generating = 1KW daily.
In a Year = 360 KW yearly.

A 50KW system = 50,000 Watt system.
50,000 watt divided by 250 watt = 200.
There are about 200 units of 250-Watt Solar panels in a 50KW system

HOW MUCH SHOULD SUCH A SYSTEM GENERATE YEARLY IF CLEAN 365 DAYS A YEAR

Based on the feed-in-tariff on ofgem website for 0-50KW installations at 40.8 pence per KWH,

50KW will generate ==> 200 x ( What a 250-watt system generates yearly )
= 200 x 360 KW
= 72,000 KW yearly

50KW IF CLEAN 100% should generate in earnings ===> 72,000KW x 40.8 pence = £29,376.00

IF CLEAN 100% = £29,376
IF CLEAN 90% = £26,438
IF CLEAN 80% = £23,500

MOST 50KW SYSTEMS IN THE UK WILL PROBABLY MAKE AROUND £15,000 YEARLY - DUE TO LOSS IN EFFICIENCY. THAT IS ALMOST 50% LOSS IN EARNINGS !!!!

INSTALL OUR ( COATING + SPRINKLER SYSTEM ) and boost your FEED-IN-TARIFF NOWWW TO ALMOST 100% !!!

To install our system on a 200-panel system, will cost around :

200 x £35 per panel = £7000 plus vat.

RETURN ON INVESTMENT :

(1) INITIAL EARNINGS BEFORE SYSTEM IS INSTALLED = £15,000
(2) EXPECTED EARNINGS AFTER SYSTEM IS INSTALLED ( AT 20% LOSS ) = £23,500.

INCREASE IN EARNINGS IN YEAR 1 = £23,500 - £15,000 = £8500.

£8500 - £7000 = £1500 } YOU WILL GET BACK YOUR INVESTMENT IN YEAR 1 PLUS PROFIT.

YEAR 1 PROFIT = £1500
YEAR 2 PROFIT = £8500 AS TOTAL EARNINGS WILL BE £23,500, NOT £15,000.
YEAR 3 PROFIT = £8500
YEAR 4 PROFIT = £8500
YEAR 5 PROFIT = £8500
.
.
YEAR 10 PROFIT = £8500

FORGET ABOUT THE EXPORT TARIFF, FORGET ABOUT THE FACT THAT YOUR LOSS IN EFFICIENCY WILL ACTUALLY BE AROUND 5 TO 10%, FORGET THE SAVINGS FROM PAYING SOMEONE TO CLEAN THE PANELS FOR YOU......ETC AT 20% LOSS IN EFFICIENCY, YOUR SYSTEM SHOULD STILL PRODUCE £23,500 YEARLY.

PLEASE STOP LOSING MONEY DAILY ON YOUR SOLAR PANELS. INSTALL OUR SYSTEM NOW, TO BOOST YOUR FEED-IN-TARIFF FOR AT LEAST THE NEXT 10 YEARS.

COATING + SPRINKLER SYSTEM IS GUARANTEED FOR 10 YEARS.

Here’s the deal for you. Come and install your system on our 70kw solar array. If you increase our kwh like you say we’ll pay for your system. If it doesn’t increase then you take it away at no cost.

Thanks alot for

Here’s the deal for you. Come and install your system on our 70kw solar array. If you increase our kwh like you say we’ll pay for your system. If it doesn’t increase then you take it away at no cost.

Thank you very much for your offer.

We definitely accept to do your job in a way that you are most comfortable with and so, below is what we think we are able to do. Kindly let us know what you think about the offer below :


(1) First we can Treat Your panels ( Cleaned, Polished and Coated ) - no upfront cost required.

Once this treatment is done and you see how shiny your solar panels look, you will be very convinced that your solar panels are already producing more electricity. Within 24 hours of treating the panels, your panels will be producing at a very high level. The treatment will take the lose in efficiency "due to dust and dirt" - to 0%. Then, before the dust and dirt start to pile up again, we will install the sprinklers to start rinsing the panels regularly say - once every 3 days. This way, the loss in efficiency "due to dust and dirt etc" will be kept to a very low percentage. 10% Maximum. 5% is what i would project. Less than 5% would usually be the case. The treatment ( cleaning, polishing and coating ) will take us just about 2 to 3 days to start and finish.

(2) Installing the sprinklers - 20% of total charge is requested.

To install the sprinkler system, we would have to re-schedule another appointment because there are things that would need to be purchased and there are site information that we would need to know. While we are on the site treating the panels, we will take all necessary site information that we need, in order to come back and install the sprinklers.

In view of this, we are proposing that, you should kindly consider paying us a deposit of 20% of the total cost, after we treat the panels because, you will start noticing the increase in daily production within 24 hours of treating the panels. The days after the treatment is done, will show a considerable increase in daily production, compared to the days, before the treatment is done.

Since we will be funding this project with our own funds, this initial 20% down payment will help us to easily procure the items that are needed to fully install the sprinkler system for you. Your system would require more than 500 units of sprinklers, attached to all the panels and it will take 3 to 4 days to start and finish. We would be ready to come back to install the sprinkler system within 2 weeks maximum, after we receive the 20% down payment.

The charge that you should expect to pay is £35 per 250 watt Plus VAT.

Therefore :

70KW @ £35 per 250 Watt plus Vat = £9800 Plus Vat.
20% down payment after Treatment ( Cleaning, polishing and coating ) = £1,960 Plus VAT.
Balance of 80% after sprinklers system is installed = £7,840 Plus VAT.

Kindly let us know, how long you think you will like to wait, before you pay us the balance.

I thank you once again for you offer and I wish to let you know that we are more than happy to work with you on the terms that you are most comfortable with.

Looking forward to your kind response.

I thought or read some threads suggesting £10/ panel wash and £20/ panel full system. Was that £30/ panel full works?

 

[akaPABLO01]

In view of this, we are happy to make it easy for customers to have the coating done as affordable as possible.

Upfront cost is £20 plus VAT per panel or per 250 watt. But we can also do, £10 plus VAT initial deposit, per panel, and then 50% share in the INCREASE IN EARNINGS for 3 years only.

From the 4th year, customer keeps all earnings. At the end of the 3rd year, we would also be able to know how the coating is doing and also, we would be able to advise the customer whether to install the SPRINKLER system or not.

If installing the sprinklers would help, we might even agree with the customer to install them on the same terms ( initial deposit plus 50% share for 3 years ).

This sounds fair to us - as we are not just collecting your money and leaving you behind, but we are walking with you, hand in hand.

YOUR SUCCESS = OUR SUCCESS.

How did you get £35?

 

[NANOTREAT.co.uk]

I thought or read some threads suggesting £10/ panel wash and £20/ panel full system. Was that £30/ panel full works?

3 options are available :

(1) ( Sprinkler + Coating ) - full system.

This is between £30 to £35 per panel. The closer you are to 1000 panels, the closer you will be to £35 a panel. The closer you are to 100,000 panels, the closer you are to £30. But, all sites, different situations.

(2) Coating only - £20 upfront per 250 watt. No share in the increase in earnings.

(3) Coating only - £10 upfront per 250 watt plus 50% share in the increase in earnings for 3 years.

And so, those are the 3 options available.

 

[NANOTREAT.co.uk]

I thought or read some threads suggesting £10/ panel wash and £20/ panel full system. Was that £30/ panel full works?

If you read the beginning of this post itself, you will see that in the projection, we quoted £35 per panel for 200 panels.

 

[Netherfield]

What are you shouting for ?

Because it's what children do when they can't get their own way.

 

[NANOTREAT.co.uk]

How did you get £35?

If you do the coating only, and after more than 1 year, you decide to install the sprinklers, it will cost £20 plus vat per 250 watt. Less than 1 year = £15 a panel.

However, for clients who are short of funds, by that time, we would consider doing a flexible deal again e.g. ( £10 initial and 50% share in the increase in earnings for 3 years ).

Coating + sprinkler = £35 ( below 250 KW )
Coating only = £20 or £10 initial plus 50% share.
Sprinkler installation after more than 1 year of coating panels = £20.

Sprinkler installation in less than 1 year after coating = £15 plus vat.

 

[f0ster]

in order to compare the performance of the panels before and after treatment you need to get a solar meter to measure the level of sun so that you can get a more accurate idea if they are better or not after treatment, you also need to wash them down and take a few readings before treatment so that you have something to compare with. the meters are not expensive.

 

[Doing it for the kids]

Or wash half on the same elevation if like us you have 2 identical sheds

 

[NANOTREAT.co.uk]

Or wash half on the same elevation if like us you have 2 identical sheds

Thanks to @foster and @doingitforkids for your suggestions.

We are happy to bring along a LUX METER. We would measure the sunlight before the treatment and record how much is being totally generated. We would also measure the sunlight after the treatment and record what is being totally generated. And the two can be compared to give everyone an idea.

Is a water meter factored into cost of running?

 

[NANOTREAT.co.uk]

Is a water meter factored into cost of running?

Thank you for your interest and question.

Yes, the water meter is factored into the cost of running the system. Later today, i will post a comprehensive report with the cost of water / panel / year.

Thanks.

Is a water meter factored into cost of running?

SYSTEM ESTIMATED RUNNING COST

If your only apply the coating on the panels without the sprinkler system, the running cost is 0 pence. Because there is nothing to maintain, the coating just works with the rain. However, if you install the coating and the sprinkler system, then the figures below applies :

We estimate £1/panel/year as the running cost of the sprinkler system per year. This will give you 52 rinses in a year - rinsing the panels once a week. Therefore, it will cost you about 2 pence per panel, every time you rinse the panels. Since the rain will also be falling on the panels, they really should be looking spotless every single time.

The running cost of the sprinkler system will consist mainly of 3 items namely : ( electricity, water and salt for the softener ). Because the water softener system is easy to install and maintain, we would usually go for this option, as long as there is access to a tap water on the site. If there is no tap water, we would utilize other options, based on the site circumstances. The calculation below is for a water softening system.

ELECTRICITY COST.

The electricity that will be used by the pump and the controller is very negligible. The pump will only run for about 10 minutes for every rinse, once a week. For instance, 1000 watt pump running for 10 minutes will use :

1KW x 10 / 60 = 0.167 KWH
if 1 KWH of electricity costs 15 pence = £0.15
0.167 KWH will cost = 0.167 x 0.15 = 2.5 pence per one rinsing session.
If rinsing is done once a week, it will be done 52 times in a year.

Estimated yearly electricity cost = 52 x 2.5 pence = £1.30 yearly.

WATER COST.

Rinsing the panel will be done once a week. Every rinsing session will take about 4 liters per panel. Using 70KW = 280 panels as an example :


Rinsing interval = once a week.
Each panel will be rinsed for about 45 secs to 55 secs.
Volume of water used per panel = 4 liters.
Total number of panels = 280 panels
Total rinse in a year = 52 rinses
Volume of water used per rinse = 4 x 280 = 1,120 liters.
Total volume used per year = 1,120 x 52 weeks = 58,240 liters
Cost of water is estimated as £1.5 for usage and £1.5 for sewage per 1000 litres = £3 per cubic meter
1000 litres = 1 cubic meter
Total cost of water yearly = 58.240 cubic meter x £3 = £174.72

SALT FOR WATER SOFTENER

The water softener will need to be re-filled with salt about once every 2 months. We will provide you with 6 bags of
20KG or 25 KG salt that should last you for about 1 year. You can always buy the salt in a lot of shops e.g. B&Q, WICKES etc A link is added here for a view of a bag of salt. A 25KG in B&Q costs £13.85 and will last for around 2 months - depending on the hardness of your water. And so, you should be fine with about 6 bags in a year. If 25KG is too heavy for you, you can buy them in smaller sizes as well.

The link to the product is below :
https://www.diy.com/departments/bwt-dishwasher-salt/254763_BQ.prd

25KG of water softener salt = £13.82
6 bags = £82.92

ESTIMATED YEARLY TOTAL COST = £82.92+ £174.72 + £1.30 = £258.94

For a total of 280 panels,
Cost per panel per year = £258.94 / 280 = 92 pence per year.
Cost per panel per rinse = 92 pence / 52 rinses = 1.7 pence per rinse.

Since water carries majority of the cost, for very big sites, drilling a bore-hole will reduce the running cost significantly.

And so, we estimate £1 per panel per year as the running cost of the system.

We also suggest an optional 5-yearly health-check visit at a cost of £250 plus VAT. We would come around and make checks on the system to make sure everything is working the way it should.

THE GUARANTEE ON THE SYSTEM ARE AS FOLLOWS :

(1) Coating - guaranteed to be active on the panel surface for 10 years.
(2) Sprinkler system ( sprinklers, pipe-line, water filter ) - guaranteed for 10 years.
(3) Water pump is covered by the manufacturer's guarantee - usually 1 year warranty.
(4) Water softener is covered by the manufacturer's guarantee - usually 7 year warranty.

PAY-BACK TIME, IF I INVEST £35 PER 250 WATT PANEL ?

We will consider two cases :

(1) Panels that are hardly or never been cleaned } Estimated Pay-Back Time is 2 Years and 6 Months.
(2) Panels that are cleaned once in a year. } Estimated Pay-Back Time is 4 Years.

***** We are using 23.12 Pence per KWH for generation tariff and 3.72 for export. We use 1050 Solar Hours based on the "energy saving trust" statement that "A 4kWp system can generate around 4,200 kilowatt hours of electricity a year in the south of England". Full report is available by clicking this link See-The-Statement *******

A 100% Clean 250 WATT system based in the south of England, receiving 1050 Solar hours yearly, should produce ( 1050 Hours x 250 Watt = 262.5 KWH ) and should generate ( 262.5 X 23.12 = £60.69 ) in generation tariff and ( 50% x 262.5 x 3.72 = £4.88 ) in export tariff.

Total tariff Yearly = £60.69 + £4.88 = £65.57

(1) 1ST CASE - SOLAR PANELS THAT ARE HARDLY OR NEVER BEEN CLEANED.

Many research suggest that, solar panels in this kind of condition can lose up to 35%. 50% lose in efficiency is not impossible. We will use 30%.

30% loss in efficiency = 30% loss in earnings.
Total earnings for 100% clean 250 WATT per year = £65.57
30% loss in efficiency = £19.67 loss in earnings yearly.
We expect the ( Coating + Sprinkler ) to reduce the lose in efficiency to about 5% Max.

After installing the system, increase in efficiency = 30% - 5% = 25%
25% increase in earnings = 25% x £65.57 = £16.39
Running cost of system is £1 per 250 Watt panel.
Total increase in earnings = £16.39 - £1 = £15.39 yearly.

Total increase in earnings in 2.5 years = 2.5 x £15.39 = £38.48 } 2.5-Year Pay-back.

It should take less than 2 years and 6 months for the system to pay for itself and after that, it begins to generate you a profit at the rate of £15 Yearly per 250 Watt.


(2) 2ND CASE - SOLAR PANELS THAT ARE CLEANED ONCE A YEAR.

In this case, we believe that the loss in efficiency will be at least 20%.

Total earnings for 100% clean 250 WATT per year = £65.57
20% loss in efficiency = £13.11 loss in earnings.
The ( Coating + Sprinkler ) should reduce the lose in efficiency to 5% Max.

After installing the system, increase in efficiency = 20% - 5% = 15%
15% increase in earnings = 15% x £65.57 = £9.83
Running cost is £1 / panel
Total increase in earnings = £9.10 - £1 = £8.83 yearly.

Total increase in earnings in 4 Years = £35.34 } 4-Year Pay-Back

It should take around 4 years for the system to pay for itself and after that, it begins to generate you a profit at the rate of £8.80 Yearly per 250 Watt without the cost of paying someone to clean the panels.

The warranty on the Water pump is 1 year, however, for your peace of mind, you can extend it to a 5-year warranty ( Parts and Labour ) for a one-off payment of £200 Inc VAT.

PAY-BACK TIME, IF I PAY £10 A PANEL + 50% SHARE IN INCREASE IN EARNINGS FOR 3 YEARS ?

THIS IS FOR THE COATING ONLY. No sprinklers is installed. The cost to coat a panel is £20 Plus VAT per 250 Watt. However, we are willing to accept £10 plus VAT initial payment per panel, and a 50% share in the increase in the earnings of all the panels that is coated, for 3 years. After 3 years, you will not have to pay us any money, anymore.

We will consider the two cases below :

(A) Panels that are hardly or never been cleaned } Pay-Back Time is about 2 years.
(B) Panels that are cleaned once in a year. } Pay-Back Time is about 3 years.

***** We are using 23.12 Pence per KWH for generation tariff and 3.72 for export. We use 1050 Solar Hours based on the energysavingtrust statement that "A 4kWp system can generate around 4,200 kilowatt hours of electricity a year in the south of England". Full report is available by clicking this link http://www.energysavingtrust.org.uk/renewable-energy/electricity/solar-panels *******

A 100% Clean 250 WATT system based in the south of England, receiving 1050 Solar hours yearly, should produce ( 1050 Hours x 250 Watt = 262.5 KWH ) and should generate ( 262.5 X 23.12 = £60.69 ) in generation tariff and ( 50% x 262.5 x 3.72 = £4.88 ) in export tariff.

Total tariff Yearly = £60.69 + £4.88 = £65.57

(A) 1ST CASE - SOLAR PANELS THAT ARE HARDLY OR NEVER BEEN CLEANED.

Many research suggest that, solar panels in this kind of condition can lose up to 35%. 50% lose in efficiency is not impossible. We will use 30%.

30% loss in efficiency = 30% loss in earnings.
Total earnings for 100% clean 250 WATT per year = £65.57
30% loss in efficiency = £19.67 loss in earnings yearly.
We expect the ( Coating only ) to reduce the lose in efficiency by around 15%.

After applying the coating, increase in efficiency = 15%
15% increase in earnings = 15% x £65.57 = £9.80
Running cost of system is £0 per 250 Watt panel.
Total increase in earnings = £9.80 yearly.
50% Share of increase in earnings = £4.90
3 years payment of 50% share = 3 x £4.90 = £14.7 } 2-Year Pay-back.
Fourth year increase in earnings = £9.80 - since, you will not be paying us anymore in the 4th year.

You should get your investment back in just about 2 years, make some profit in the 3rd year, and from the 4th year, you should be making £9.80 yearly as profit for every 250 Watt that is coated.

(b) 2ND CASE - SOLAR PANELS THAT ARE CLEANED ONCE A YEAR.

In this case, we believe that the loss in efficiency will be at least 20%.

Total earnings for 100% clean 250 WATT per year = £65.57
20% loss in efficiency = £13.11 loss in earnings.
The ( Coating only ) should reduce the lose in efficiency by 10%

After applying the coating, increase in efficiency = 10 %
10% increase in earnings = 10% x £65.57 = £6.50
Running cost is £0 / panel
Total increase in earnings = £6.50 yearly.
50% Share of increase in earnings = £3.25
3 Years payment of 50% share = 3 x £3.25 = £9.75 } 3-Year Pay-back
4th year increase in earnings = £6.50 - since you will not be paying us anymore.

You should get your investment of £10 a panel back in about 3 years and from the 4th year, you should be making £6.50 profit yearly for every 250 Watt panel that is coated.


After 1 to 3 years, we will analyse your system and see if you can still improve the efficiency of the panels by installing the sprinkler system. If you can install the sprinklers and still make a tangible profit, we will give you the projection. At that time, expect to pay £20 a panel. If a customer can not afford the £20 upfront, we will consider doing the previous deal again ( £10 deposit and 50% share for 3 years ).

Would be far more effective spending the money on foil reflectors but most installations have not been designed to have foil reflectors added later.
