ᐅ Commissioning a photovoltaic system and charging an electric vehicle.

Hello everyone,
Our photovoltaic system is scheduled to be put into operation soon. I have several questions related to this topic and hope to get some helpful ideas.
1. I am currently dealing with all the tax paperwork. Monthly VAT returns through Elster and so on seem relatively straightforward. Still, does anyone have a link, guide, or website that explains this topic clearly for beginners?
2. The topic of one or two meters for household and heat pump has come up here several times. For now, I have decided to stick with two meters. Since ideally, I want to power both the heating and household with the photovoltaic system, the PV vendor recommended a "power to heat" setup. Does anyone have experience with this and can offer advice? The electrician who will install the system soon was more cautious and wanted to cover only household electricity with the PV system. Which is better?
3. Now, this is a bit off-topic: Since my car has broken down, I am considering getting an electric vehicle. Does anyone have experience with how well charging an EV through the photovoltaic system works? In winter, of course, it’s probably less effective since the car won’t be at home during the day. The wallbox is already ordered. However, I am still unsure whether this makes sense. The car would stay in the garage continuously on weekends, so there should be enough hours to have it fully charged by Monday.
4. Now this is even more off-topic: Since house construction and the upcoming outdoor landscaping are costly, an unplanned vehicle purchase hurts the budget a bit. Since I want to keep my reserves untouched, I’m considering leasing an electric car. Thanks to environmental incentives, the monthly costs should be relatively low. I had an appointment at a dealership yesterday. When I compare their offer with those online, there are sometimes very large differences. Common leasing platforms also offer deals from dealerships, but often cheaper than the local dealer. Does anyone know why there are such differences and whether online offers are reliable? Has anyone leased a car online?
Thanks and best regards

Currently paying over €2,000 (approximately $2,200) per year for household and heat pump combined.Is that on paper (just calculated) or actual? A 350 sqm (3,767 sq ft) villa? At €0.25 (about $0.27) per kWh, that would be around 8,000 kWh.Regarding the “E-box”: as a private individual, it’s hard to get below €350 (about $385), unless it’s just a movable seat with a second exterior mirror.

Stefan2.848 Jul 2021 17:54Calculated on paper based on outdated data from 12/2020 until now. I come to 3000 kWh (3,000 kWh) for the household and about 4500 kWh (4,500 kWh) for the heat pump.
And many of the base models already have decent equipment.

Based on outdated figures from December 2020 until now, the calculations on paper show about 3000 kWh household consumption and around 4500 kWh heat pump usage.
And many of the base models already come with decent equipment. It should be within a reasonable range, even without knowing the exact conditions.
Today we received our billing from December until now. Heat pump €60 (about $65) additional payment. Household items nearly €500 (about $540) refund. Consumption should be similar. Previously, it was logically only an estimate from the provider after moving in.

60 model: €339 + €20 maintenance (€30 maintenance plus) + €11 extended warranty
80 model: €477 + €20 maintenance (€30 maintenance plus) + €11 extended warranty

Household consumption is independent of whether there is a heat pump or an oil boiler. 4500 kWh is not that low. However, important data is missing for evaluation.
But here it’s about photovoltaic systems and electric boxes. 😉
