Maybe you hate pumping gas in the cold (or heat), or you care about the environment. Maybe the latest gas prices and general inflation has you thinking more about stretching your money. Perhaps you simply think electric vehicles (EVs) look cool. No matter the reason, you're excited about your next vehicle being an EV and you're not alone! The EV market share is set to [expand to 30% by 2040][1]. The [US government provides a handy comparison tool][2] to show that the cost of ownership of an EV easily beats owning and operating fossil fuel vehicles. Despite this, EV charging costs can still hit you hard in your wallet.
你讨厌在寒冷或者酷热的时候加油，你关心环境问题。最新的油价和通货膨胀让你更多考虑挣钱的问题
One of the most elegant ways to solve cost problems in general is to apply open source principles to accelerate innovation. Fortunately for you, this has been done in the EV charging area to find a way to get low-cost electricity and low-cost chargers.
To control the costs of EV charging, first you need low-cost electricity. In the old days, that would mean going from oil to coal, which is not a step up. Today, as it turns out, [solar photovoltaic (PV)][3] devices that convert sunlight directly into electricity normally provide the lowest-cost electricity. Coal companies are going bankrupt because they can no longer compete with clean solar power. This is also why [solar power is seeing explosive growth all over the world][4]. Many homeowners are putting [solar panels on their roofs][5] or on ground mounts in the backyard to cover all of their home’s electric needs. But how can you charge your EV with solar energy if you have limited roof area or a small backyard?
