Solar Power Expectations

[Exfarmer]

Me too,I don't know if I can change my export purchaser or not.Currently on 5.7p(pre April 1st 22)which is index linked and alters April 1st each year.Im currently with Eon and have been since the start 2013 with an extension built in 2015.Im not really clued up on this at all.

Normally these are done on 2 year contracts, but if you contact some like @AlexMcGowan he will be able to check your situation.
I am assuming of course that you already have a HH meter and are not on sub 30Kw presumed export

I do have a HH meter ,fitted when I extended the original 15kw to 49.8kw which means I have two different payments for generation due to the 34.8 extension fitted 2 years later.

You need to get this sorted as soon as possible as the export is at historic highs. The change from one company to another is handled by the two between them

These are my average daily generation rates for three 50kw arrays.

There have been instances where inverters have tripped off and I've been slow to notice, and the like, but it should give you some idea.

Even in the thick of winter we're getting 1kw per day per 1kw of panel. A 100kw system should give you ~£800's worth of electricty per week during the sunnier months based on current market rates.

How many panels would produce 100kw in summer?

100kW or 100kWh ?

Simple answer to your question, taken literally: None, there are no panels commercially available that can produce 100kW.

What do you want to know?

 

[Highland Mule]

Slightly more helpful answer:

100kW of output would require ~300 panels of ~330W (1/3 kW) each, or more/ less if panels are rated differently.

Each installed kW of rated output (~3 panels) would produce around 100kWh per year, mostly in the summer.

So your answer is either 3 or 300, depending on your question.

How long is a piece of string that weighs one gallon? The post you quoted was listing production value, not KW or KWH. Please go back to post #13 and understand units if you want to get anything out of this.

ok pedants, I’ll ask the question again using the other part of his post.
In the final paragraph he stated that he was receiving circa £800 per week for his 100kw system based on current market rates.
Now
How many panels does it take to produce that £800 per week?
i apologise for assuming that his post entailed his system working at its 100kw capacity (which I assume is actually kw rather than kWh as we are not talking about amount produced in an hour, but how much his system produces in a week)

I suppose my earlier question should have been
How many panels do you have in your 100kw system to receive £800 per week in summer?

Thanks for being patronising, see my latest post.

It's not pedantry, it's getting things right.

The answer to your question is in post 28. If you don't understand that post, then read post 13 first.

Thank you.
That makes a lot of sense.
The OP saying “I’ve got 300 panels” would have also made sense, which is what I asked in the beginning.
This is sometimes the problem with this forum, instead of posting helpful information like you have posted on post 28, people also seem to take the sneery option too.
But thank you anyway

He may not have 300 panels, as panels come in different sizes. He has 100kW of panels and I have made an assumption - his post was accurate and mine is a guess. Why you need to understand how many panels he has is beyond me.

FYI, my working is based on two things - a recent quote I saw was for 380W panels, and a local install which has 240W panels. 3 panels to the kW is a guess on my part.

If you had asked the right question, you would have got the right answer. The fact that you didn't and the doubled down in post 26 made you fair game for 'sneery' responses IMHO, especially after I had put what I did in post 13.

Except my post quoted his post, which normally means that you want that person to answer, not someone else to second guess you.
Your post 13 answered a question which I did not ask you
The reason I was interested in the amount of the panels is that if he said 50 I would think it’s an unbelievably good investment, but if he said 500 then the returns are much more marginal.
sometimes people are just interested?

 

[Wisconsonian]

You asked nonsense questions, and got helpful answers. I don't see why you're still whining.

Perhaps Fogg hasn't been back, or just doesn't care to answer a nonsense question, or maybe doesn't know how many panels he has, as everything is measured in KW, not number of panels, and with 100KW he probably didn't design the system himself.

I’m done. I just asked him how big his solar array was. I didn’t ask you any questions at all and didn’t get anything useful from you either. I’m not whining, merely interested in the size of his system so I could work out on my own whether it could relate to my farm and whether it is worth me making a similar investment.
Your kWh kw pice of string answer may have been relevant in your own mind, but I knew what answers I was looking for.
Highland did answer my question in a general way, which was as much detail as I needed.
Don’t worry, I’ll stay out of your discussions next time

Be helpful if we knew where these panels are located .....

 

[bobk]

Do you need planning for panels on a roof ? got south facing shed 120 ft x 22 ft x 2 , as in 2 south facing elevations

Unless the shed has planning conditions regarding roof colour then I believe the answer is no. All mine have never had planning, butr they were for agricultural use on Agric buildings.
if you arte concerened i would speak planning sure they will be sympathetic.
However myt view has always been , the less they know about these things, the less chance of being rated. Which if it is not agricultural they certainly can
