I'm looking into making an off-grid EV solar charger so I'm wondering: What is the slowest possible AC or DC charging possible? Is it possible to charge at 100w for example? More specific: What is the lowest wattage (or amps*voltage) that can be communicated to be available from an EV charger...

Hello, I am wondering if it is possible to charge a battery system from a small solar panel over time and then charging my EV truck off that battery? Buying a big solar system in my area is cost prohibitive and would then make it more expensive to drive and charge my truck then just a regular...

i've got a big solar panel grid (with 20 cells) that feeds the grid with at least 5kw on a good sunny winter day. it doesn't currently do anything else. except... i did connect an outlet to it, in which i can use to charge my power banks and even a macbook. however, this electricity must come...

I am starting a EV recharging network using as much renewable energy as possible. There is much more to it than "as much renewable energy as possible" but let's start with that. I would like to conduct face to face interviews with EV owners in the greater Portland Oregon area. I would like...

Hi, I am a student at the Eindhoven University of Technology and currently, I am doing my master thesis regarding the feasibility of solar roofs on Electric Vehicles. See below an impression of how this would look like on a model 3. As I would like to gather some input from model 3 owners...

We buy used Volt ,Bolt (not many avail) and SPARK EV battery packs. They are great for use in a conversion EV. The cooling system is easy to hook up and use in the conversion. This will give them a very long life. We also reconfigure the power connections between cells and use these battery...

Is Tesla residential solar panel offering competitive as a standalone solution (I have to assume not, but I have not done the research). Does Tesla offer any incentives to new or existing Tesla car buyers to install solar roof panels at the home where the Tesla will be charged nightly? More...

You may not even notice it but Solar in it's many forms runs the world. We use light everyday and sleep at night (most of us) when the Sun goes down. On a cold day we stand in the Sun if we can and on a HOT day we move to the shade. Our homes have awnings and eves that give us shade. Homes in...
