I am really sorry for such a silly question while your answer is too much in detail. In these days when I search forum, my head is spinning and I don't know what I am doing in this post. I just found that my house is not qualified for solar panel because of construction code. I must be totally crazy because I feel I chose the wrong car for my circumstance. I might have strong mental resistance on Mitsubishi PHEV. Really sorry for my silly question, again.The size of a solar system depends on the slope, size and direction of your roof and your expected power requirements, which depend on the size of your family and how you currently use appliances, lighting, etc.
Consult a solar installer, tell them you want to be able to charge your car every two days, and budget on using about 10 kWh per charge (unless you're always going to charge from 'empty', in which case bump that up to about 13 kWh.)
My daily average usage went from 1.5 kWh (single person in a stand-alone home) to approximately 5.5 kWh after I bought the PHEV. At the time, I was driving the car to work every day and recharging approximately 2.5 times per week.
A 5.5 kW system (or more) seems pretty standard these days. (Three times larger than mine).
My current system is only 1.5 kW. (i.e. generates 1500W at solar noon one day per year.)
By the way. The reason why my home was only consuming 1.5 kWh per day, is down to retro-fitting thermal insulation in the roof, double glazing, solar/gas hot water heating and window shading/insulation (External roller shutters).
Rely on your current power bills for your starting point and work from there.
