Can the people fitting your solar also fit the charge point? You'd potentially save the VAT.
Edit: They'd also have full responsibility to get the solar charging working and avoid blame passing between contractors.
If it was to happen, I will have agreed to install the panels and the eV charger installer is happy to connect.
However at present not affordable, and at age 66, we need to try and determine the £ for solar and the £/time when me may regain the cost.
The car was more than we were expecting, as we " decided" to buy with just the £1,500 grant, ( when looking all £ were out of date as the price for the car was £30,400 not the £27,800 we were expecting)with £2000 required for a new fuse box and Zappy.
If our electricity supplier is soon going to give us back £3/ 5hrs charging each nite we charge 12 midnight till 5am, MAYBE this will be the best " buck" back or saved.
Me thinks again at age 66 if we look at the MG5 as a saving at approx 25% of an ICE and 8,000 miles a year over the 7 year warrantable life of the car, and the no road tax and £85/ year service ( Richmond) besides the use for now free in congestion zones, we will be doing ok for now.
Without too much future knowledge as to how and when government will " get" get us eV'ers back £ wise.
Oh and we think our MG5 is a fine car indeed suits us as now a single car couple as opposed to a car each couple.
AND I have just got me bus pass £ savings all round
