Assessing dedicated storage for rooftop solar

[kristopher]

...It's not SunPower's first look at combining solar power and energy storage. "We have worked on the Lanai 1.5 megawatt battery storage project," said Blunden. She added, "This is the perfect experiment to assess different types of storage." Ice Energy uses ice as storage, ZBB is a flow battery, and Xtreme Power is a battery system.

"This is an important step in understanding the economic effects of storage, and an extremely useful step for understanding the commercial and industrial customer's storage requirements."

Blunden spoke about energy storage and variable generation resources. With "the low levels of penetration in the western grid, ancillary services will continue to manage variable generation," said Blunden, citing an LBNL report on the ability of robust grid networks to withstand variable generation.

Blunden pointed out that photovoltaics and variable generation can reach enormous penetration levels and exist on a grid without storage. She cited the 7 gigawatts of variable resources on a 70-gigawatt system in Germany and 3 gigawatts of renewables on a sunny day in Spain. She said, "We have the data -- it's just in the EU."...

1. my rooftop solar generates a modest surplus but storage is toooo costly really. too bad cuz

if we had a big earthquake and lost the power grid I would still have some power capability.

2. Next-gen capacitors are going to be in production soon

Something insane like 3 Farads in a device the size of a toaster. We got to play with a prototype in the lab last year.

3. I suppose translating this to English is just too much work.

Which is why the rest of us don't pay attention to you.

5. Speak for yourself. Lots of us understand the simple terms

used in this OP. If you don't, there's a solution for that. Until you educate yourself a little (try Google), you could just skip these threads.

6. speak for yourself.

if you can't find the time to pronounce multi-syllable words, or suffer from reading comprehension issues, please don't group the rest of us along with you.

I find Kristopher's posts insightful and informative.

7. I second that

4. Since it is in English....
