The Solar Power Reddit


The Solar Power Reddit

Solar Power - the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic effect.

Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. The 392 MW Ivanpah installation is the largest concentrating solar power plant in the world, located in the Mojave Desert of California.

As the cost of solar electricity has fallen, the number of grid-connected solar PV systems has grown into the millions and utility-scale solar power stations with hundreds of megawatts are being built. Solar PV is rapidly becoming an inexpensive, low-carbon technology to harness renewable energy from the Sun. The current largest photovoltaic power station in the world is the 850 MW Longyangxia Dam Solar Park, in Qinghai, China.

The International Energy Agency projected in 2014 that under its "high renewables" scenario, by 2050, solar photovoltaics and concentrated solar power would contribute about 16 and 11 percent, respectively, of the worldwide electricity consumption, and solar would be the world's largest source of electricity. Most solar installations would be in China and India. Currently, as of 2016, solar power provides just 1% of total worldwide electricity production but growing 33% per annum.

MPPT as a DC UPS

Long story short, I live in Ukraine and we are starting to have regular power outages again. And I have a 3d printers that I use to make some important things. Can I connect power supply to the mppt instead of solar panel and power plug directly into the printer? I believe that if I there is not that big of a load, the mppt will be fine. What do you guys think?

Edit: I do have lifepo4 batteries , that I forgot to mention

Starting solar project

Starting a solar power project. Really wanting to learn but with some semi-real stuff. What would be a decent brand to buy for a 300w panel, charge controller, and battery? (I have an inverter) My intention is to try to get my small office off the grid. I recognize one panel and battery may not be enough, but i just want to start this journey....

Homer database data

Does anyone here have access and knowledge on how to read solar panel power data. I’m thinking from the HOMER database in particular would be very helpful…

Superbeast headway x4

elp! I have 4 superbeasts- for a solar bank. I hooked up one and it ran my ac for 30 mins no sun. Then I hooked up 2 1/2 and it ran for 5 hours with the sun. Clearly it took a while to drain (starting around 13.3) and slowollw went down down to 11.5 then shut off.
Well I hooked up more to make 3, and it won’t even run ac for 5 mins. Power starts 13.5 and takes steep dive quickly and ends up at 11,5 under 3 mins. I don’t get it!!!! The power I’m monitoring is from 4000 inverter Is it Because they are not balanced yet? (In the mail) or the way I have them hooked together? Positive to positive negative to negative

I don’t understand. I had 8 deep cell batts all hooked up in parallel and would run all night long before inverter would beep

I have a 2012 Chevrolet Volt. What do I need to run on only solar?

So I use my battery up every single day, on either my commute or weekend activities.

I have a large stand alone double garage, and I’m thinking of putting solar panels on the roof.

Im thinking, if I have enough surface area and a battery back on the wall to store the 11kwhs needed to charge her I won’t need to pay for any electric at all !

Anyone know what I’d need and who can supply such a system ?

Thinking it could be stand alone…

I live in the south of the UK.

How do Thermal Solar panels avoid boiling the water?

Hi all!

Bit of background info I'm an electrical / control systems engineer in a steam turbine plant and I'm contemplating installing a thermal solar panel to heat my hot tub to save a bit of cash on electricity bills. My idea is very crude but it should work relatively cheaply.

I want to use a second hand good quality thermal solar panel connected to a central heating pump which I will connect to a temperature switch etc to turn the pump on and off.

As I'm not familiar with Thermal Solar but I'm familiar with steam systems - my concern is when the pump is stopped you will still be heating the water uncontrollably I assume. I don't want to generate steam so I'm not sure how the panels would regulate this?

Solar panel i'm planning on using is a Kingspan FPW30 or similar

Central heating pump will be a Grundfos UPM3 or similar.

Any advice would be greatly appreciated

Take Charge: The American Home Owners Guide to Solar Power

I recently picked up this new Ebook and now I'm officially taking the first steps to getting off the grid.  It's an easy read with step by step instructions on how to incorporate solar energy into your home.  No, I am not an affiliate for this book and I do not get paid for referring it to you.  Its a great book and an excellent place to start if you've ever thought about solar energy. It comes with a couple other free short info books for off grid living and a ton of great worksheets to organize the project.  Let me know what you think.

Winter Wil come again

Hello! I'm moving to what can be described as "middle of no where". I'm very concerned come winter that I will lose power. I'm really wanting to dabble into solar power as a back up option for my two leopard tanks and a 20 gallons fish tank. If anyone has had any experience I would appreciate it greatly!

Spruce Power finally resolved an old SPAC lawsuit

As you may remember Spruce Power (XL Fleet back then) went public through a merger with SPAC. On December 21, 2020, the merger was completed.

Shortly after, Muddy Waters Research released a report stating that the information in the Proxy was not accurate. This led to the stock price huge drop and moreover, XL Fleet revealed that it was being investigated by the SEC.

After that, there was a big scandal and investors filed a lawsuit against them. And just recently Spruce Power agreed to pay a $19.5M settlement to the shareholders to end the litigation. So, if you have been trading XL/PIC you can file for the payment here or through the settlement administrator. Hope it'll help!
