I have 10kW of PV and as I slowly make my home all electric, consumption will only go up so on the surface it kind of makes sense.
At present, the majority of my PV production goes back into the grid. In the evening when we cook etc I'm importing. As you say Douglas, timing ones life around PV production can become a chore, and the freedom sounds good, even out the supply and demand.
For me, at the moment, the "wheel's still in spin" and I need to crunch the finance figures, but in my mind it looks good. I've also still to some more battery research as to which system would suit my needs.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17871&Focus=302020#Comment_302020 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17871&Focus=302020#Comment_302020 Sat, 17 Jun 2023 06:57:04 +0100 cjard http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17871&Focus=302021#Comment_302021 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17871&Focus=302021#Comment_302021 Sat, 17 Jun 2023 10:13:41 +0100 djh Posted By: cjardIf you can get a symmetric tariff does the grid notionally become one big battery?It might but AFAIK there's no such thing here. You get charged for consumption at retail rates and paid for export at wholesale rates, at best.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17871&Focus=302022#Comment_302022 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17871&Focus=302022#Comment_302022 Sat, 17 Jun 2023 12:29:33 +0100 Peter_in_Hungary Posted By: cjardIf you can get a symmetric tariff does the grid notionally become one big battery?
No symmetric tariff here but we have annual reconciliation which means that whilst the import price (including grid charges) is retail and the export price is wholesale production price because the reconciliation is annual there is no point to getting a battery. The target for a PV installation is to end the year at zero i.e. import = export.

Next year the plan is to go to monthly reconciliation for new customers and most PV installers are saying this will kill the market.

IMO annual reconciliation makes sense because you can use the grid as a big battery and surely the environmental and financial cost of a domestic battery / kWh is more than wind or PV / kWh on the grid.]]>
