I have 20kWp of ground mount solar, and would like to extend this by 10-20kW. My DNO (Scottish & Southern) tells me that I need to upgrade my grid connection at a cost of £20k for any further installation to be allowed. Clearly this sends the ROI the wrong way!
I understand that an option would be to programme the inverters on the additional array(s) to limit export to the grid from the site, i.e. during periods of high output when I am not using "enough" on site to lessen the export. This will happen fairly infrequently, and by skewing the new installations east and west by a certain amount (as opposed to the existing due south configuration) we can continue to make more money from more PV...
The problem is that we have to persuade the DNO of this course of action, and get their agreement before proceeding (spending money....).
Anybody else wrestling with a similar problem, or has experience of using the relatively new ability within inverters to limit output to the grid during high output?
Thanks!
