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.

Help Reading Chart on SP
Hello, looking to see if anyone can provide insight on this chart, in case I’m misinterpreting it. Its a usage and consumption on my solar panels. If I’m interpreting this I’m producing quite a bit of solar power around .75 but I’m still getting more imported in. It shows I barely consumed .20 of it the last two weeks. Am I reading this right? Anything stands out to anyone? Want to make sure I thought this tru before approaching Sunnova.
Side note: I just purchase the consumption meeting which is why there’s only a few months with produced details.

Solar power for Apartments in India
With the increasing demand for sustainable energy solutions, I propose an innovative approach to enable apartment owners in India to harness the benefits of solar power. Many individuals own homes in their native towns while residing in apartments in cities for various reasons. To encourage the adoption of renewable energy, the government should consider allowing these individuals to install solar projects at their native properties. After accounting for the electricity units utilized for transmission to the grid, the remaining generated units should be eligible for adjustment against the electricity bills of their respective apartments. This initiative would not only promote the use of clean energy but also provide financial incentives for apartment owners, thereby contributing to a greener and more sustainable future. Comments and critics are welcome. Any new way of doing this is also welcome. May be Government is also thinking in similar direction.

What’s Going On With Maxeon Solar This Week?
Hey guys, if there are some Maxeon investors here, I guess you already know about the rumors we are listening to this week (and the “Elon fever” that these rumors brought to $MAXN, tho).
For those who may not know, Maxeon was having a rough patch because last May stock dropped around 35%. Basically, last year MAXN stopped shipping to SunPower over allegations of breach of contract. But then, in May’s report, the company announced a huge revenue drop, which revealed massive cash flow problems.
So, with this news $MAXN fell, and investors filed a suit against them for hiding its financial problems and dependence on SunPower (if you were an investor back then, you can join and check the news about this case here)
But now, with these rumors of a possible buy from Tesla (btw that isn’t even confirmed yet), $MAXN is recovering to July’s numbers, so maybe we will see a resurrection after the hit of May’s news.
Anyways, what do you think about this news about Tesla buying? And do you think that Maxeon can recover even without the SunPower contract?

Why does it not keep the lights on
Hey smart people anyone able to help with the power? The inverter makes the noise in the video and wont keep the lights running consistently after i unplugged the temperature sensor on the charge controller and reset it.

Bought a house with panels but no battery
I have a 7.56 kW system. Would love to use a battery for backup power and/or a EV or PHEV car eventually. I’m new to batteries.
Does brand name matter? Does buying a battery from Amazon get me just as far as a Powerwall?
Is there a layman’s way to size batteries? All the solar co’s will “design” a system for me but not sure if I’m getting got by marketing

Looking for guidance on a power station.
TBH, I'm a bit of a noob. I'm looking for a power station that can power my fridge when the power's out, and that I can use to power movies when camping. I was looking at Anker products, cause I'd heard about them before, but then I had a friend recommend the Laligra Power Station. Honestly, not ever heard about that brand until recently. But then I came across Bluetti. Looks like the AC200P L has a pretty solid reputation. Any idea how these would compare? Any experience with either product? I like that the Laligra power station has wheels, but there's an Anker product that's pretty similar. I just don't know where to start, lol.

Clam Power
Clam Power Giant clams are four feet long (!) and live in shallow coral reefs off the coast of Palau. Their innards are sparkly blue and operate as perhaps the most efficient solar panels on Earth. Researchers found that in a model of the clams’ first step of photosynthesis, during which chlorophyll absorbs a single photon, the process had an efficiency of 43 percent—more than twice that of most current solar panels and three times that of tree leaves.
Why this is so cool: The clams’ fleshy mantle contains an orderly arrangement of photosynthetic algae, which convert sunlight into food for the clam. The mantle’s surface is lined with iridescent cells that channel light down toward the algae. And the clams appear to inflate or deflate the mantle to optimize the amount of light reaching the algae.
What the experts say: This bivalve might be a great source of inspiration for more efficient solar harvesting technology designs. Alison Sweeney, a Yale University biophysicist and co-author of the new research, hopes the findings might inform the design of algae-stocked bioreactors.

How bad is this shading
New boy here, this might seem a stupid question but I have installed the solar PV panels on the end of a barn and I am about to start on the rest of the hardware. It faces directly south. I knew I would have some summer shading but wish to optimise autumn, winter and spring production because here in SW France, we get a lot of sunshine. I am using 2 strings of 6 panels with a hybrid inverter. Will the shaded sections of these panels totally ruin any current flow when they are shaded?

Fixed Position or Solar Tracking Solar Panels?
I'm in high school and I'm working on a group project where we are creating a plan for a water treatment facility for a remote community. We're having trouble deciding whether to use fixed solar panels or panels with a solar tracker. I'm leaning towards fixed solar panels because of the lower maintenance and lower costs. However, solar tracking will give us more efficiency over the long term. I am wondering you personally would choose in my situation.
