Hi, I fitted a texecom veritas excel alarm to a friends house last year, he has a garage that is now being used as a store for his business and wants this protected. Do any of you know if a remote pir is available for this alarm. Getting a cable over to the garage would be a bit of a...
Hi, can't get hold off solar people at mo, to ask what is required in terms of MCB required for their solar panels. when I met them ages go, they said just leave a spare way and I'm pretty sure they said they would put in a 4mm cable. Anyway i'm going to install a board complete with RCBO's.
As...
I had a panel install done about 18 months ago and i stupidly said it was ok for them to cover the window (only access point to the roof from indoors), but now i know i have made a mistake and I'm looking for a rough ball park figure for the 6 panels to be moved probably about 1m along to enable...
Hi all,
I need to perform the following pid control using an altivar312, want to read the DC bus voltage (that is the solar panels voltage), and use a pid control to keep this voltage constant in order to make a mppt follower. The idea is to change the frequency driven to the motor. If dc bus...
Hi All, thanks for taking the time to read this!!
I'm currently trying to decide on a solar PV system to get installed on my house. I've a budget of £9K and whatever I don't spend on the solution will just get paid off the mortgage.
I'm limited to 16 panels/4kW. Roof faces SE and there isn't...
Hi guys
I have just accepted a job as a junior alarm engineer and would like to get up to speed as quick as possible.
I wanted to find out if anybody would be able to help me with the basic installation, set up and fault finding of a Honeywell Galaxy and an Accenta intruder panel - something...
Evening All,
can anyone advise of the best means of electrically heating an a large area 50x30ft, containing electrical control panels , the aim to prevent any moisture ingressing the electrical equipment( motor pumps etc.
Thanks
A pretty basic question here, but something we haven't come across before.
If a 4kWp is installed, as far as I understood it, and addition would then bring the original installation down to the rate of the new size FIT bracket: for example, add 2kWp and the whole system would now be on the...
Afternoon.
I have potential customer questioning whether all black panels will perform as well as panels with a white backing on the basis that they will become hotter more quickly affecting energy generation on warm sunny days.
I can understand the logic but have never seen hard evidence to...
Further to my recent thread:
Will a Solar PV install payback sufficiently for pensioners when bought with a loan?
I know without a loan the payback could be within 10 years (i.e before customer reaches age of 76). If a loan is factored in though this will push payback to sometime in their...

No mention of make of panels but if you hear about or are offered any, bear it in mind.
Must be expensive panels as reported to be £50,000 worth - on a ground...
Hello, I would like to know the approach and calculation how if I are to design 10MW of solar grid tie solar pv system.
Lets say that each panel have the specification as follows..

Hi
First post, so please be gentle. Am about to take the plunge and have a 4 kW PV system installed on a south south east facing roof.

16 x SolarWorld Mono Black (250w) panels
or
12 x Sunpower E20...

Evening all..
Apologies if this is a bit basic. This is the first post I have done on the solar forum as I just do domestic electrics, but i fancy putting a solar panel on the roof of my van so I can have 2 lights in the back (low powered - haven't really looked so dont know the wattage) and...
