Economy Solar power now less expensive and more reliable than fossil fuels

[Prefect]

Battery usage is not just for battery back up, it’s used so that you can power your home while energy prices are high, and then refill your reserves when energy prices are low. The batteries by themselves would take some time to pay off, however, with the ever volatile price of electric, it could be sooner rather than later. You also need batteries if you want to go off grid, and that’s totally possible. Future technology like sodium could lower prices significantly, as long as it’s widely adopted.

The utility companies are going towards batteries as a way to expand capacity, and the way they operate is to charge higher during peak hours, and you as a customer can do the opposite, get the best rates, with a battery system, backup is secondary.

You are talking about things in manner that is segregated from the actual economics of things.

You MIGHT want to overlook the cost "disadvantages".

Even in an urban setting a portable 5kw generator and transfer switch is worth it's weight in gold. When needed. It will run a window unit AC, keep your fridge cold and phone charged.

A whole house option of solar will take 10+ years to pay back so that isn't so great considering most people will sell in that time. However, knowing you have power when your lines or grid is down is pretty fucking comforting.

My whole life runs off 3100w of solar and 1500AH of 12v batteries.

Lefties propaganda thread.

Was planning on getting solar because the way my electric bill was going up I would probably break even from the getgo. Problem is CA just cut the price for solar power bought back by the electric company by like 75% so that killed that idea.

You should debate them on this topic. Show them what for...

You might convent DC to AC.... with invertor and such solutions are known 100 years plus in row.

Ofc problem is that there power is generated when sun is shining ... ... ...

Accumulators are very expensive and stuff to manage their leading and usage is expensive.

While might you get normal power in house when sun is shining and gird isn't working will depend from system and invertors you had installed.
Hybrid might generate 50 Hz or 60 Hz frequency in solo mode, without power in gird...
Joined invertors are cheaper..... and if you will not have centralized power supply they can't generate 50 Hz or 60 Hz ...AC and therefore will switch OFF.....


Also I don't think you know how nice are market prices in dry sunny august ... when there is low ammount of water and hydroelectric power plants does have best timeframe period to prepare for autumn rain and sparing floods season. So repairs and check ups.... ofc.
CHPP owners aren't willing to sell just electricity and not much heat plus they does needs prepare for heating season......
So repair and to do maintenance.

Water is not much, fossil fuel storages are filled for heating season, additional reserves too, wind is almost 0....

Sun is shining, fridges and conditioners are running a lot....
When market electricity price on hourly basis might be ... 0.4 -0.95 € / 1 kW•h ....
Then solar panels on office roof doesn't looks like waste of money.
Especially cos conditioners and fridges are taking damn a lot in hot sunny day....


Ofc I agree that wind energy is super difficult to balance... even in autumn it might blow danmn a lot and quickly calm down, then repeat.

Ofc if you have wind farm and pumped storage hydroelectric power plant it is cheaper and more usable.

Plus pumped storage HPPs are used also to accumulate excessive production during night and weeknds and to release when there is demand.
Plus they are usable as energy reserve for black start of grid and to be used as SK compensators to help keep frequency In grid.

Europe does have experience with these 45 + years ....
Only problem that suitable location is needed and it is very expensive to build these too.
Otherwise PSHPP stuff does work well, proven 45 years in row.


Wind stuff is with low predicatbility and very huge expenses to balance grid...

Do you think the Spanish and Portuguese don't have the engineers? Or the ones they've got are stupid?

I don't think it's the case, personally.......... I don't think it's viable, especially when you take into account the basic principles, that's why, their looking at more and more into Nuclear......... And why the hell hasn't China become the leading users of the very products they manufacture.........

Thay aren't stupid. Hybrid invertors are MORE expensive. Not alone to talk about accumulators.... and stuff to convert from them output into AC too is expensive.


China is building next coal fired power plant each month, also will build more hydroelectric power plants and are doing this today.

They also does have PV power plants and solar collectors to heat water and damn a lot
....number is increasing each day. Also biogas solutions...the same.


Reality that they are not using too much wind stuff and mainly thus for them is export of components, spare parts etc...

 

[SandisLL]

I don't use PV panels for home. Solar collectors with heat accumulators YES.for water heating.
I also have generators, 2 peaces, they might use : one gasoline , one is small diesel.
I don't have EV car, therefore PV panels stuff for me isn't so actual. Plus if I don't have electricity from grid....then sun usually doesn't generate anything reasonable anyway.
