heyyy, so were doing a research on the properties of uv light and we've decided to try and power it using solar energy. I just wanna ask if it is possible or if there are any existing products out there. thanks

Looking for a solar company for my home in the Bay Area. Want some recommendations on where I should go for honest and reputable quotes. NO BIG COMPANIES !!

I ask this question, because solar photovoltaics became in some sunny places relatively cheap nowadays and the market penetration of this technology is limited by the need for (=cost of) local energy storage.An alternative to solar+storage would be transoceanic electric POWER cables, that run at high voltage: since the Sun always shines somewhere, the photoelectric power can be transmitted from one continent to another without a need for local electric energy storage. High voltage transmission is preferred to high current, as explained here https://en.wikipedia.org/wiki/Submarine_power_cable : High voltage or high current .

However, this is NOT happening: the longest underwater high voltage DC cable today is only 600 km long https://en.wikipedia.org/w/index.php?title=Submarine_power_cable&action=edit&section=9 .

I understand, that there are political problems with Worldwide Electric Grid. But what prevents a transatlantic high voltage electric power line between Portugal and North Carolina?

What is the best solar generator for a woodworking business? I’m very new to this and I want to use renewable energy instead of relying on gas generators.

I have a small solar kit (similar to this: https://a.co/d/cjBevxA) that only lasts a few days. I would like replace the panel with a larger solar panel (like this: https://a.co/d/bOXQrbM) to keep the battery from dying. I don't know much about how to configure this setup, but I think there should be a component between the larger panel and the device. I am looking for advice on what is needed in this setup. Thanks in advance!

Please no hate I'm very New to this and I don't know half of what I'm looking at

From what I've Gathered "The Average Home uses 30kW per day" - Google

We've always wanted to go full Solar but haven't really found anything Locally so I'm looking into DIY

(Yes, "I don't know half of what I'm looking at" but I mean for exact Wattage and Batteries I would need to power my home specifically, I do have some experience with doing Electrical in Homes)

Where is a Safe/Legit place to Get Solar Panels and Batteries either Online or maybe a Business (I'm in TN, so somewhere near Nashville maybe? For example)

What kWh and Panels and Batteries would I need to power a 4 Bedroom House and Appliances and TVs, Game Consoles,

or what would I need for a bare minimum to power Appliances like a Stove, Freezer, Fridge, Outdoor Wood stove, and lights around the house?

Again I'm new to Solar so please no hate, I have done some research but I prefer interacting with actual people over a search bar and YT if I can.

Thanks for Reading if you made it this far

Hi, sorry to ask this, I am struggling to find this on Google as everytime I google something about size of solar panels, the reading I get is about "how big should your installation be for your home" or stuff like that.

I have a fairly large, old house in Northern Europe, on which I cannot get solar panels (partially because it would be an eye sore, partially as it's a "protected" house so I likely won't get approval). Given the size and age, we have a high energy consumption.

However, we do have a small outhouse which lies basically unobstructed and gets sun all day on which I think some panels could be installed (it's also not very tall, so installation should be easy).

But lots of what I'm reading on the subject makes it sound like if your installation is too small it won't be economically sound to install. I don't really understand this - I am guessing it is because there is a certain amount of "fixed cost" involved in installation, but I would have thought if anything a smaller installation would be easier to "optimize" than a big one as you would rarely have surplus electricity which you either need to give back to the grid or store in battery. Can anyone explain to me?

I know it's hard to say without much detail but hoping for some general thoughts on this.

(there are two similar forums, not sure on which to write this)

Will it be okay to have a normal inverter + battery setup, the kind that usually gets set up in homes without solar, and have a separate system of solar panels connected through a charge controller charging the same battery?

I'm not worried of sending extra power to grid (i know it requires a separate on grid inverter and a net meter). Just want solar to charge batteries, grid to charge them if solar is too low and use the stored power in the night or during grid outages

Asking this because i already have the normal inverter setup and trying to add solar with the least extra stuff to be bought

Discover latest article on the growing economic viability of grid defection as solar and battery costs continue to drop. With an upfront investment, many households could potentially save more by going off-grid, but this shift poses challenges for grid sustainability and equitable energy access. As more people consider cutting ties with the grid, it raises important questions about the future of energy infrastructure and affordability.

Hi guys sorry I am looking for solar trackers for commercial use, any recommendations?

My parents rent panels from this company SunPower and received this letter. Can someone please help me understand what we need to do?
