How can this be possible? It's because electric vehicles are much more efficient than combustion-powered vehicles (see below), so they require less energy input. This means even solar in Western Washington is enough that a household with reasonable access to sunlight can produce all the energy for more than one car.
If you used to buy gas, but switched to electric, you have probably noticed that the savings are beginning to add up. Why not earmark those savings to pay for the solar panels that provide all the annual energy needed to charge your EV(s). If you do, the time it takes to recoup your solar investment can be as little as six (6) years if you purchase your system in 2020. If you wait until 2021 it will take about 6.5 years due to the reduction of the tax credit for that year. If you wait 'til 2022, there will be no tax credit for household solar panels, but it will still only take about 8 years for the money (you save by not buying gas) to pay for your solar panels, and then it's all free driving after that. That could be 25 years or more because solar panels are very durable. The solar panels at my house are already 15 years old and still produce the same amount of electricity that they did in the first year. Climate change in the Pacific Northwest has added more sunshine each year, counteracting the expected slow degradation of the solar panel output (about 0.3% per year)
