In an EV jump start, you are essentially augmenting the 12V battery, like you would with a traditional jump start, but there is no high current surge like there would be during the jump starting application on an internal combustion engine vehicle. The jump starter provides auxiliary capacity to the system to allow it to power up. So, yes, jump starting an EV is sometimes necessary.

As the above clearly shows, EVs do indeed run on 12V batteries. You can't start an EV (i.e., make it run) or operate an EV (all the 100+ ECUs - Electronic Control Units - run only on 12V current) without 12V battery power. It's this 12V battery - critically necessary for any and all vehicle activity - that gets recharged by 12V parking canopies.

The electronic interface between 12V solar panels and 12V batteries is known as a "charge controller". A charge controller only costs 10 bucks.

Maybe as the crow flies, but driving time its closer to Portsmouth than the lake. It's also more integrated with the towns along the Spaulding corridor. Living here I've always felt closer to the seacoast than the lakes region.

And these announcements never cover the co2 cost of clearing the land, creating the panels, shipping the panels, and when they are no longer fructose, disposal of the panels. I don't know this company, but I've worked with a bunch that cut a ton of corners to get the things up and violate NEC, such as the array in bedford on the Goffstown line. They put on paper that they are charging for and getting the expensive, recyclable panels, and ends up using the cheap hazmat disposal ones. Solar power just isn't there yet. Not to make it worth while to destroy habitats. Covering parking lots and schools? That's a start, but why not roads?

It's been clear cut several times thought out the centuries. 1700s for the king. 1830s for sheep farming. Late 1880s for materials. Burned down after the hurricane of 1938. Logged throughout the 20th century. And now will be cleared again for solar. It's about 90% white pine in there. Nothing too special.

Nice ad-hominem.

Re-read what I wrote. I'm well aware of the reasons for this project but I am sad that it is happening.

The economics don't work for putting solar panels over parking lots. They also don't work for putting them in ponds and lakes.

Regardless of my stance on this project it isn't a water installation. I strongly suspect that will not change because I expressed my fefes on Reddit. Linking to how solar could be installed on water is in no way relevant to this particular installation.

While some police departments and states have concerns or laws against window tinting for various and plausible / logical reasons, eye contact, officer safety, visibility in low light — the government’s own studies have found no empirical evidence that front window tinting has any effect on vehicle, pedestrian or Officer safety. I personally was against front window tinting for all of the reasons above - having looked into it, I had to change my opinion. As someone who lives half the year in Florida for work reasons, I have learned to appreciate window tinting as I’m sure anyone who lives in the southern states might where sunlight and reflections can be blinding.

A book from a library isn't going to harm children. Maybe this group should be looking at the fact that everything from social media to advertising has so much sexual content. Yet kids, apparently, aren't supposed to notice. Also most kids are exposed to porn at age 10. Yet they're trying to remove a book that actual gives kids factual information about their bodies.

Curious though is that based on raw output or actual applied usage. People play games with the numbers quite frequently. I don’t know the exact formula but the power coming from those panels probably does offset that much at the panel however inversion to AC power will cut that down significantly because we can’t transmit DC power across large distances, the voltage drop is too significant. There is also voltage use when returning that power to DC for any battery operated thing that is used. So in reality I’m very curious if soup to nuts those numbers are what they say they are or just the feels good numbers associated with raw power generated by the panels.
