Now there are some parts of the US (such as Hawaii) where the cost can be higher than $.50/kWh, but that is still less than the properly calculated cost of a solar system with batteries.
If the utility power is very unreliable, although not expensive, then a system with batteries may make economic sense if the cost to you of being without power is very high. At that point the real cost per kWh of solar PV needs to compared to the alternatives which include generators and batteries and just charging the batteries off the grid when it is on.
For the country as a whole, using generators or PV is better for the system than trying to charge batteries when the power is on. The latter just increases the load on the utility leading to even more problems and blackouts.SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment

11-cents from the greedy power company for all the electricity you can use. Or 65-cents to 80-cent in very limited quantities for battery cost not including anything else like panels, controllers, wiring. labor, maintenance, and replacement cost.
You would be a fool to take anything off-grid if you had commercial power available.MSEE, PEComment

Yes, it means exactly that. Once you take into consideration the cost of replacing batteries every 3-5 years, the cost per kWh is almost always higher than buying it from the utility company.

The electrical is disconnecting in US?
Those prices for components that is manufactured in USA or in China?
Do you recommend for me batter and invertor suppliers?

PV is Photovoltaics.
As I understood that lithium battery is more expensive than FLA battery. What about Ni batteries?
I do not know if the friends here are talking about components that are manufactured in USA or in China to know the reason for this high cost.
How much it cost the solar panel in USA that generates 300 Wat? And what is the dimension for this solar panel?

A guideline for panel prices in the US is that you can get deals on panels over the internet for prices of $1.00 per watt or lower. Or you can buy new top quality (Sunpower) panels for over $4.00 per watt.
Those prices do not include shipping. Shipping is a lot cheaper when you order a full pallet at a time, and can wait a while for delivery.SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment

And the FLA battery of 2 V and 1000 AH is costing 350$ for 3 years life time is USA manufactured, right?

US made panels are far more expensive than imported Chi-Com panels. A US made Sun Power 300 watt panel made in China cost $1200. We can also buy imported Chi-Com made 300 watt panels for $300. Funny huh?MSEE, PEComment

By the way, those batteries that cost 350$ for each 2Vx1000 AH, they are manufactured in china or usa?

I don't know in the USA, in Caribbean countries, The Rolls brand and Trojans brand are most popular brands in Jamaica. we also use Trace and US Battery brand.
I am using Rolls 4000 series batteries, I hope I can afford the Trojan industrial line battery or the Rolls 5000 series when I replace my batteries next time.
The Rolls battery are made in Canada? and the Trojan batteries should made in the USA.Comment

Tesla battery
Hello All;
I would like to know the best (recommended) providers (factories or manufactures) for batteries to be used for solar, wind and UPS systems of 10 KWH, 20 KWH, 30 KWH, 40 KWH and 50 KWH.
From the other side, I would be very thankful if someone advise me about the recommended batteries to be used (if to use lead acid or lithuim-ion or Ni).
Appreciate the kindly help and thanks a lot in advance.
Regards
BilalComment
