Energy : Production, Storage, Efficiency, Solutions

I didn't realise how much of a price difference there is between Europe and the USA in cost of a solar installation!!

I just watched 'Undecided with Matt Ferrell' on Youtube about his five years experience with his solar installation.

In 2018 he had 9.49kw of solar panels, with inverters etc, installed at a cost of $29,609, he received a 30% Federal Tax Incentive of $8,883 which brought his cost down to $20,726.

In 2021 I had 5.94kw of solar panels, the inverter and a 16.7kwh LifePo battery installed, here in Europe for a cost of $18,000.

The system Matt had installed did not include a battery at that time, he added a Tesla Power Wall later, my battery was about $11,000 so about $7,000 for the rest, which if I'd increased it to 9.49kw would have cost in the region of $11,000, my costs didn't include any financial incentives from the Government.

5 Years with Solar Panels - Is It Still Worth It?

... I am wanting to have more usable capacity, even if it is only a few percentage more.

Figured I'd put this here ::

1300 DC Fast charger is a solid number,
now maybe put 30 large solar panels on your roof Walmart to power these chargers.. DC~DC

Is America Ready for Walmart’s EV Charging Network?

Walmart is planning to build DC fast-chargers at its Supercenters, Neighborhood Markets, and Sam's Club locations. But will customers use them?

I don't own or drive EV.. but enjoy parking lot sunshade during heat of Summer months.
This is our local store in Placerville, CA

From time of ground breaking to finish this solar panel system was completed in just a few weeks. I wouldn't want panels on my roof, but I would consider a carport similar to these installed.

7 years from now...

Considering how much work is out there for underground bore rigs, electricians, charger manufacturers, electrical companies (upgrading feeds, swapping transformers, etc) permitting, etc... I'd say 1) that sounds about right and 2) years too late.

Walmart can have anything fast tracked, they just snap their fingers.
I look at other corporations, not even having any plans for this,, that's years too late/

The concept of these solar carports could be a very successful business for commercial & residential installs, for many years to come.
For those in high school students wondering what they could go into & then service down the road dot dot dot

Locally, the trend for retail seems to be to install public L2 chargers convenient to existing infrastructure. The two party tricks I've seen are piggybacking off of parking lot light standards or installing the chargers adjacent to utility infeed points. The light standard trick has the simplest installation process - generally no concrete cutting with the main complication being the retrofit of a control relay for the light(s) that would otherwise be physically powered off during the day - however these tend to be the lowest-power stations out there at 6kW. The latter format are more involved and generally subprime parking locations but minimize run distances and can potentially provide power up to the 19.2kW limit for L2 chargers if one is so inclined and provide substantial range recovery in the 30-60 minutes that one it apt to spend at a shopping center.

Electrification in general is a trend that's building momentum. There's a lot of opportunity out there - solar installations, BEV charging stations, heat pumps displacing gas furnaces/water heaters, electrical panel upgrades/reworks, implementing load management solutions for residential and business premises, energy storage installations - that suggests there will be a broad expansion of electrical work for decades to come.

Maybe I'v been under a rock, but I didn't know E-Fuel was even a thing.
Factoring in all the steps, can't even imagine the cost per gallon just to produce.
,, then transport, taxesssss, retail markup, several other things.

A Massive E-Fuel Plant Is Coming to Texas

E-fuels are a fledgling energy source, but the production of a reliable well could enhance their potential.
