For those interested!
My grand plan comes to fruition - though I wish I'd actually had a plan...
I did it in 2 stages, 1st stage was before I found this thread (doh!).
1st Stage:
7x 320w Roof mounted panels (WSW facing)
1x 2kw Trannergy Inverter
1x Eddi
1x Harvi
1x BER
Associated switches etc.
Cost €5400 Total, €3600 with grant rebate.
2nd Stage:
12x 340w ground mounted panels (SSE facing)
1x 5kw Solis Hybrid Inverter
1x 5Kw Puredrive Battery
6x Tigo Optimizers (added once I could see bottom panels shaded ~November to ~February). Picture was taken at 9am in the morning in November so that shading is from trees and other structures low on the horizion. I might add optimizers to all the panels though as I have spare pennies.
Cost €8100, €7500 with grant rebate.
Expected savings per year based on CURRENT energy prices (which I think some people forget are very unlikely to go any direction but up)!
Electricity: ~€110 per billing cycle - €660 p/a
Oil: ~€100 p/a (Based on using 2 ltrs of oil to heat hot water for showers etc over the months when boiler is not needed to heat the house.
Based on that alone my payback is ~14 years
.
But, hoping that once FIT is announced and I will be able to sell the expected lots of surplus in summer months those numbers will change. Plus long range plan will be to get an electric car I can charge with a zappi - not sure how that might change the whole payback scenario.
Lessons learned - I should have planned better what I wanted to do, but I was so happy with first seven panels I got a bit carried away
Also, the interest free credit / payment plan from a major energy supplier I bought the first seven under is not the great value it first appeared - once I figured out the amount I paid was way over the odds I should have shopped around.
Hopefully this is useful information for anyone getting a quote etc. Feel free to PM me if any more detailed questions.0 -

How'd you get the grant twice?0 -

As slave1 says, I got the solar panel grant for 2.1kw first time, and then this time I got the battery grant. Or at least I'm hoping I get the battery grant
With the ground ones, I'd be resetting the angle of those panels every month, so that they catch the sun best as they can at noon. They are far too flat in my opinion, and I'd say you're getting little or nothing from them right now.
Dare I say, if they are flat due to the rear set being shaded by the front set, well at least shove the back set up.0 -

They are at ~26degrees, 9 degrees off optimum. And actually are more angled than the fittings they are mounted on which are designed for ground / flat roof mounting.
No chance of front shading back, camera angle deceptive.
Haven't had a good day to check performance really - optimizers only went in yesterday, before that the front panels shaded by house shadow - I was aware that might be an issue. Plan is to eventually optimize them all from piggy bank money 0 -

Hi,
Did you source and install the ground mounted panels yourself.
On the same path as you I think, going with an installer and grant aided install on my garage roof and then looking to add some ground mounted panels next year.
Was it hard to source the fittings and materials for the ground mounts?
Regards
LIam
No, i had a great installer who was willing to try this; I don't think he'll be doing it again though as he ended up spending many hours trying to get it level Fair deuce to him he was determined to make it look decent even after I said it was fine a bit helter skelter.
The mountings are the Renusol one's available from a well known Irish online company. They are effectively plastic buckets that you place on the ground (I'd recommend concrete not what I've done!) and then fill up with some weight - any ballast will do. Then the panels just clamp on top.
Let me know if you want me to PM you the guy who did it for me, he'll love to hear another person looking to do it

This may be of interest to a few here. There is currently a review of Ireland’s Long-Term Renovation Strategy 2020, which is accepting public submissions
The submission is in the form of a set of on-line questions at:
https://www.gov.ie/en/consultation/b0eae-public-consultation-following-the-publication-of-irelands-long-term-renovation-strategy-2020/#
The document being reviewed is available at https://assets.gov.ie/90215/288fca06-a376-4110-87e5-5cfa45917f03.pdf
Q3 and Q11 are important ones for people installing panels.
Q3 - increase the 12m squared limit on a roof for panels please Mention the Limerick case where the person appealed and a large system was left in place.
Q11 - FIT asap please
Tomorrow is the deadline for should only take a few mins.0 -

Excellent! I was able to submit the form today. Here's my response to question 3 in case people want to modify the wording a bit and submit in support. Feel free to update if there's anything I missed - I just threw this together in the few mins break I had from work. Also it's not in Q3 but one of the other questions asks if current plans are sufficient to meet the Government's targets. You should mention that the current plans aren't sufficient to meet the Paris agreement emissions targets which the Government has signed up to and that this change would be a step towards addressing that issue.
Currently the size of retrofit solar installations which would be exempt from planning permission requirements is limited to 12 square metres at residential properties. This applies whether the system is installed on the roof of the homeowner's property or on the curtilage/grounds of the property.
The relevant restriction is outlined in the latest planning and development regulations available here:
https://www.housing.gov.ie/sites/default/files/legislations/planning_and_development_regulations_2001-2020_unofficial_consolidationannotated16.09.2020.pdf
The relevant text was inserted by article 5 of S.I. No. 235/2008 – Planning and Development Regulations 2008 and reads:
"The installation or erection of a solar panel on, or within the curtilage of a
house, or any buildings within the curtilage of a house......
The total aperture area of any such panel, taken together with any other such panel previously placed on or within the said curtilage, shall not exceed 12 square metres or 50% of the total roof area, whichever is the lesser."
This is an enormous barrier to retrofits by homeowners in Ireland which would permit sustainable energy generation. Using current solar technology 12 square metres would permit a maximum of c. 6 solar panels, or c. 2kwh of peak generation. The average Irish household uses c. 4200kWh per year (source: https://www.cru.ie/wp-content/uploads/2017/07/CER17042-Review-of-Typical-Consumption-Figures-Decision-Paper-1.pdf) or 11.5 kwh per day. A solar system with 2kwh peak generation would only cover a fraction of that usage.
By contrast, a 6kw system which would be technically feasible with a single-phase power supply would supply most of a homeowner's daily usage. This however would require an area of c. 35 square metres - almost triple the size currently exempted from planning permission.
An 11kw peak system would take up c. 65 square metres - over 5 times the size currently exempt from planning requirments. An 11kw system would supply enough power for both household usage and the charging of an electric vehicle for most homeowners. Alternatively excess production could be fed back into the grid for use by neighboring properties.
The current system of requiring planning for installations larger than 12 square metres in size is a significant barrier to renovations. The drafting of plans for the purpose of application for planning permission would add at least 50% to the cost of such a system. Furthermore planning requirements significantly delay the installation process. The time costs imposed on the homeowners of going through the planning process significantly shift the cost/benefit equation away from the choice to install solar.
Since about half of the cost of installing a solar system are fixed and relate to the labour of the installation crews rather than the equipment, small systems are less economically viable. Larger systems by contrast are less expensive on a cost per kwh basis because the fixed cost of installation are spread over a larger peak production capacity. This is another significant barrier to retrofits for sustainable energy generation. Increasing the size exempted under planning regulations would shift the cost/benefit equation in favour of solar.
Other European countries including Northern Ireland provide exemption from planning requirements for solar installations which cover the entire available roofspace. As a result a far higher proportion of homes in Northern Ireland have installed solar systems.
Therefore a target should be to remove the 12 square metre maximum size from current planning regulations and to instead permit homeowners to use the full scope of their roofspace for solar installations.
Furthermore, the 12 square metre limitation makes no sense in the context of ground solar installations within the curtilage of homeowners' properties. As previously mentioned, an 11kw system which is technically feasible with a 3-phase power supply could power both the typical Irish house and an electric vehicle. Such a system would be roughly 65 square metres in size and could easily fit in a corner of the garden of many Irish properties. An increase of the size limitation for installations within the curtilage to c. 60 square metres would permit homeowners to maximise the benefit to the environment from retrofitting their properties with solar systems while maintaining a reasonable limit to address other considerations such as neighbours' view etc.0 -
