Hi All
I would like to invite you to comment on the solar install I am planning for my house. I consume around 10,000 kwh a year due to energy thirsty hobbies and with the crazy new tariffs here in the UK, I decided its time to invest in PV and be a little greener.
Although I have some basic electrical experience and have built a successful off grid solar system for my caravan, I am planning to install the system myself with the help of a builder friend however I have a solar qualified electrician lined up to inspect, connect up and sign off the system.
I would greatly appreciate your opinions on my proposal!
I have a 1960s pitched roof semi detached house which has the rear pitch facing south/east and the front pitch facing north/west. I have calculated the weight of my roof (roughly) and the PV hardware will weight considerably less than 15% of the roof weight so I understand no structural building control sign off is required.
PV:
I am considering going with JA Solar JAM60S10-335/MR BF Half cell panels and using online calculators, I have estimated the following energy generation:
String 1 - South/East, 3.685kw of panels (11x 335w), connected in series, Estimated production per year = 2,617 KHW
String 2 - North/West, 4kw of panels (12x 335w), connected in series, Estimated production per year = 2,662 KHW

Inverter:
I have purchased a Solis 1P6K-4G 6kw single phase inverter which has an AC limiting feature. According to the manual, each MPPT can accept a 4kw input and an input max voltage of 600v. The AC limiting feature will be set to 3.67kw and an application will be submitted by the Electrician to the grid (UkPowerNetwork) to comply with the rules for inverter installs over 3.67kw. The inverter will be mounted on a block wall in the loft with an AC and DC isolator for the in and out supplies. An armored cable will be run outside from the inverter to the house consumer unit (I don't fancy pulling floors up) where it will feed into a basic electrical meter before feeding into a 32a MCB on the CU. The CT current clamp to control the AC output will be mounted on the live grid supply tail.

Solar diverter
An Immersun solar diverter will also be installed to divert any unused solar power to my 3kw immersion water heater (and under floor heating in the future). The current clamp will be mounted on the live tail from the grid supply and the diverter will be mounted next to my CU connected to its own 16a MCB.
Here is my system diagram:
What do you think? Have I missed anything critical or calculated anything incorrectly.
Any advice would be greatly appreciated!
Thanks!
