Trying to get back 20W per panel of 400W with water cooling seems silly because you need (1) pump energy (2) water resource. However this way you also get a cooler roof back too. You also can make it a closed loop with radiator. I guess they should sell panels with built-in water block for water cooling.

Enough nonsense. You're too poor to buy those cheap toy panels, with old perc technology cells, of course they're cranky to the tilt. Not by chance, perc technology have been out of mass production for a long time. Are you with pocket money trying to get rich by lying to people, delusional? Invest it in powerful panels of the latest cell technology, and you will see that the result is below 3%. Mr. Solar beginner, first grader.

Does this unit output power when it is not plugged into the grid or the power is down?

So so dumb

Time to liquid cool them like a computer chip.

The water needs yonbe at the bottom to increase the heat differential

This would be great to plug into a mango power battery system. The conversion loses are outwayed by how far from your garage you can put it. Plugging it in to the outlet is dangerous because during a power outage, it could zap a line worker. And expensive because the power company could sue you for $20k if no one is hurt. If you have a generator switch installed by electrion go ham. Just make sure you are off grid mode.

Dude seriously? So you made this system but are using it on a house that already has solar with a net meter? If you want to make a system great, let's not connect it to your house, violate a shit ton of codes, not get authorization from the utility, and think it's fine without a bi-directional meter. Lots of bad info here. If you want a system like this feed it into an all in one battery/inverter. Then use a generator panel to power loads. For fuck sake don't plug it into a 120v outlet.

They have been making water cooled, sometimes called Dual Purpose, solar panels for over 10 years now, I know, I sent them the idea for it about 15 years ago.....

It's good idea for some architects to build a solar-roof with water channels in the roof itself touching solar panels. More energy + warm water.

Well, the calculation shouldn't be based on the angle of the panel - but the angle of the sun vs the panel.

I've seen plug n play solar on Amazan maybe since 2017. But the more I think about it, one would eventually need/install more-proper solar installation is must. There is still niche for this like condo-apartment with a nice balcony that faces the sun.

That is not "surprising" that is common knowledge ...

Most of the time, the added cost and complexity of these solutions are just not worth it. Simply adding more panels is often the best approach to improve power output.

What about using that clear ceramic film they have now for automotive windshields? They stop a lot of heat transfer

Baloney!

It's really not complicated at all if you don't tie into grid. All you need is a transfer switch so that either the main power is on or the solar system but not both at the same time. It sounds like your close to producing enough power to run 100 percent off your own solar.

So is thwre like a water block you can get to put on the back and just pump it to a rad in the shade? Or is that not possible

Great video, i just rewatched your previous video with the amazon set up, and this popped up. I think I'll look into this new version. Keep up the good content.

Better to use an off grid string inverter on a critical circuits panel with grid input when battery and solar isn’t sufficient. The power is clean and you have100% self consumption. The technology has advanced greatly and is not expensive.

Power company doesnt allow .ask power company 1st

Try using a fan blowing air on the back side of the panel.

You must not connect an inverter to anything but a dedicated branch circuit. Having any other devices on the branch risks overloading the circuit should a fault develop.

but heat makes loss & flat ones were not vented under? so loss can be pitch & heat buildup?

That control panel don't look to be NEMA 3R rated?

Be careful with that graphite pencil!

Have you had a problem with delta pro ultra sold by amazon? The q/a:"Is ac pass through possible with 120v input? A:Use the c20 outlet for a bypass mode with a 120v input. There is no bypass mode for 240v input. AC output is turned off at this time."

No Certification then it wont be approved by an inspector!

Have you tried useing misters to cool panels?

Have been an admirer of your videos for a long time because you make a rock (me) get it. I had to say it, this time you lost me when you said I did not need to connect this and that. I am visual learner and would have learned from actually you doing the plug and play without all the ofter stuff. Eventually I will get it seeing your video a few hundred times. Keep up the great work.

For people interested in doing this: DON'T! Fresh water is so much scarcer than we think, and using it like this us extremely wasteful. If you want more power, get more panels. If that's not an option, look into "hybrid" panels. These are normal solar panels with a water cooling loop behind them. This way you harvest both power and heat from the sun. That heat can be used to preheat your water heater, so it uses less power, or it can be used as an input for a heat pump, or it can be used to heat a swimming pool. This way you're getting more power AND usable heat from the sun, instead of just wasting water. For the record, I know this was just an experiment, I have no issues with that, I just want to prevent people from taking this a bit too literally.

Dont do this!! Your local inspector and utility company will shit a brick if they catch you. There are code violations so it wouldn't pass inspection, and your utility company requires inspection and an interconnect agreement to connect to the grid.

Try using the radiator from the back of a fridge or AC unit, to collect the heat - difficulty is coupling the thermal transfer cost effectively - perhaps it could be potted with plaster of paris which is pretty cheap and should conduct heat a lot better than air which is a great insulator.

This is so illegal it's scary.

If you don't have a way to shunt the power to a standby Battery Bank, you are wasting a TON of money! Because, if all you have is a Grid Tied setup, when the Power goes out, your Solar Panels are worthless. I went with a SEPARATE setup. When OUR Local Utility hiccups, I can annually with to a Battery backup system, INDEPENDENT from the Grid. Your Technical explanations ARE correct, however, I personally do NOT like Grid-Tied only systems with no Battery backup!

I think this guy should first go back to school to learn about electricity before attempting any more videos. Why would he connect solar panels in parallel and maximise current rather than voltage? P = U I and P = R I², so from these two equations it is obvious that current must be as low as possible to minimise the losses. Solar panels should always be connected in series to maximise the voltage and minimise current.

It is much less efficent than I expected, thx.

Lets keep it simple electrons always take the shortest route just plug this into your closest high drain appliance and YOUR POWER WILL GO TO THE APPLIANCE simples❤❤❤❤

Right when you mentioned the extorsinist HOA you are screwed up

I could see pumping to an elevated tank when you have excess energy and then gravity feeding water to the to the cooling system could be worth it in big enough systems, say 15 - 20Kw

Count the code violations boys

Nice! Was hoping for a follow-up to your previous setup

It would be nice to see the effect of shading on one panel in the case of series or parallel connections.

So, if I got 100 watt and 400 watt panels, but both have current outputs of 6 amps each, I should be okay hooking up in series?

Used panels are not eligible for the tax credit.

Yes, the Current generated remain the same for the entire range of temperature, but the voltage will increase the lower the temperature it is, that's why the power difference between cooler and hat panel is small, around 10-20%, cuz the cell junction voltage is not changing that much, and the current is the same. The voltage increase relatively logarithmic with the decrease in temperature. Such water system is good for auto washing of the panels 😁

Is it legal to connect powergenerating device to grid?

This NEP inverter is illegal for plugging into an outlet. It is not UL approved for grid intertie use and if your utility learns of your installation, you going to get sued by the utility.

What are you feeding with the 120v?

Scott, can you make a video about a completely off-grid DIY solar setup that is using an Ecoflow Delta 2 Max to power a mini split? Have a detached shed project in mind that doesn't currently have power, but I'd like to convert it to a WFH office. Edit: Got the inspiration from your recent shed project. Would like to do similar, except expand upon that with more panels and the Delta 2 Max (with extra battery, which I already have).
