RE: A Year of Powering Dreams: Steem Solar & Electricals
Congrats, congrats! :)
This is extraordinary! Keep it up, I believe we're changing the world with all PVs ;)
By the way, do you have any experience with residential sodium ion batteries?
Thank you so much, I appreciate your support. And sure thing, the world is gradually embracing this renewable energy..., I believe it's a matter of time..., everywhere would be PVs powered.
To be honest, I just discovered that sometimes February this year and how effective and low cost it os compared to Lithium. Over here in Nigeria we have Lithium which is mostly used by the rich per se.
I had made a few research about it few months ago, I think it's a good innovation. I would doing a few more courses on renewable energy and it’s new inventions.
Is it popular in Bulgaria?
:)
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 :)
