RE: A Year of Powering Dreams: Steem Solar & Electricals
:)
I've been following the topic on the tech news for months, I don't think it is much popular anywhere apart from China but recently I've been running into innovative EU companies that are trying to make it available, like this Italian, for instance: https://www.heiwit.com/
I am particularly interested into 10kWh residentia batteries, as my family owns a small rooftop PV farm (5 kWh panels installed). Unfortunately Bulgarian energy sector is massively overruled by shady people so there are practically no grants to buy PV equipment. (Some on paper and ads, but generally shit) We paid ourselves for the equipment and licenses (took thousands of EUR and 1 year to get them all) and since then I've been waiting for better batteries to equip as I suspect I'll have to pay for everything myself too.
We do not sell energy back to the grid, only one of the fees I have to pay is about EUR 1500 and guess how long that 5kW has to produce to pay just that fee, given they pay you less than EUR 0.10 per 1kWh and then there are a bunch of other stuff that I also have to pay and again, wait for at least an year for all permits.
Sodium batteries are best for stationary stuff as their density, so far, is less than Lithium ones but then, the price is much better. I hope in an year or two, they will be mass adopted.
Also, Na-batteries work at better temperatures and practically no fire hazard. In Bulgaria, winters sometimes have -20C and colder, while the summers get to +40C and hotter :)
It would be the best of it's kind when it's finally in circulation in the world.I think many will go for that instead of lithium due to it's price.
Over here in Nigeria, I'm not sure we have anything like a grant to use in purchasing such. And we don't have to share any electricity to the grid. We don't have such laws here.
Indeed!
The fire hazard is a big concern too, for example, I cannot insure the PV modules in the house, as this is some fuckedup policy by all local insuring companies.
Well, that distinguishes the normal countries from the ones with high levels of corruption (like Bulgaria and Nigeria) - in the normal ones the governments create incentives so people invest in a greener future, while in the latter, it's about not loosing country of the energy sector :(
A friend in UK told me his electricity company would do the installation and help with all permits, etc. and they have to pay about a quarter of the market price. A percentage of the new house come with preinstalled PV panels, again, country plans for lower carbon footprint.
I heard somewhere that in Germany the regular grants cover for about 70% of the total price of the PV residential farm.
I hope to live up to see this change here, but frankly, I doubt it will happen soon.
Interesting!
Some of those companies in UK indeed buy back the surplus of the PV production, of course, prices a bit lower than what would be on the free market but then they help with the most of the hassle before that so that's justified, right?

I would love to have that here, in Bulgaria, although I realize this won't happen anytime soon...

I think that with regards to that matter, micro-investments will lead to macro-changes, even revolution. If another source, cheaper, is invented, that would change everything even sooner.
