Um where do you get those numbers from? Shockley–Queisser limit is 33% for single junctions, no?

Aye, there is a big difference between what's technically possible in the lab and what is viable for mass production.

The Shockley Quiesser theoretical limit for single junctions is at ~33%.

Some companies will move vents and stuff to fit more panels. A sunpower rep (I think it was them) mentioned that as an option instead of a tilt mount if necessary.

Idk if this is a joke or not but that's called a Dyson Sphere

Could have a pool too. Damn thing take a lot of power

From what I understand, after 2028 the new panels/accumulators won't arouse unwanted interest from a local utility board. Have to wait until then.

A couple of things to note about these cells are 1 that they are made with indium, and there is not enough indium on earth to meet our needs. 2 they are made with arsenic, which is toxic.

This is why I plug my power-strip in to itself to achieve infinite energy.

are those a viable option? seems they'd be super expensive, limited availability (don't think i've ever seen one in real life, imagine only super wealthy people have them right now?), limited styles, etc.

they seem so neat tho. i just haven't tracked what's going on with that tech since before the pandemic 😅

Future you doesn’t feel like bringing you back panels?

It depends on what you install. If you install 13kWp then sure it may take a few years. But if you install like 800Wp then the amortization may be less than 5 years, without selling excess energy or subsidies.

There are actually so many factors you can't compare your solar panels and electricity consumption with random strangers on the internet.

• he might live much further away from equator than you or just in an area with a lot of cloudy days

• he might have electric heating so his consumption is much higher

• his roof might be much smaller than yours

• his modules might be older so producing not as much power per square foot/meter

• might have larger family or simply different lifestyle with more cooking/ night activity

• he might have an electric car

>Almost all PV is connected to the grid, there's no point in having a battery

It really depends on your usage patterns. For me it could be a great investment to get batteries if I had PV. The Feed In Tariff is about 20% of the cost of grid supplied KWh which means that having a battery to cover the period between when the sun goes down and the off-peak rates hit could save a decent amount of money. I would have to gather data (power consumption vs time of day) and do the maths to figure out if the cost savings would pay for themselves though and I am not going to bother to do that without having the option to put up PV in the first place.

Can only go backwards and return. :(

Remind me of this.

Solar def has more maintenance cost because it’s so diffused.

I think you’re making that up. Why aren’t you using better panels from the future?

Supercomputer and a time machine. Solar simply can't give me what I need yet.

It's not a battery. It's a set of generation sources that have to be ramped up and down to meet demand. And ramping up variable sources to meet peak demand times tends to be expensive for the grid.

Great answer, thank you!
