Would be a bit high if it were panels only. The article doesn't mention what method they're using to step the voltage or if the 175 watts is the low voltage panel rating or the actual output.Is that a good cost-to-benefit ratio? I seem to remember finding better deals on the internet.
eeeeh, no.Is that a good cost-to-benefit ratio? I seem to remember finding better deals on the internet.
The beauty of DC appliances. :thumb:eeeeh, no.
Allow me to explain. These units come with an internal inverter, so they make AC current. Which makes them easy in terms to being able to plug an appliance in to them. So you could run your PC during the day time with one.
I Live on a farm, I need to be doing stuff during the day, not messing on a PC. So I would need the PC on at night, when the solar array would be off.
Also I have a well. Wells are commonly 220VAC.
The common thing to do with solar is: they are all DC so wire them straight into a bank of car batteries. Charge up the batteries all day long, connected to a 120VAC inverter, you have electricity at night for your PC, or if you live near a city then even a TV.
From those batteries you can also have a 240VAC inverter for your well.
They are tried to market these in a manner to imply that they need no wiring.
But you can not combine two to make 240VAC, so their use is limited.
Im now wondering if there is a DC battery tie in? and not including the batteries is most likely a way to keep overall cost down, people new to solar may simply not realize they need something to store the energy at night. or then again depending on the limited use a day time solar system could be all that one needs. (depending on the use)The 'ideal' setup is a couple photo arrays putting out DC charging a battery bank, a windmill putting out DC to charge the same bank, and a hydro-plant putting out DC to charge your battery bank.
Then one 120VAC inverter for each 15amp circuit in your house.
Plus on 240VAC inverter for your well.
In this manner you have access to 12VDC [for the really cool LED lighting in your home], and 120VAC for regular appliances, and 240VAC for stupid things like wells and some A/C units.
A single panel that has no battery, and includes it's own inverter is really kind of lame.
Yeah I know, go to bed when it gets dark, get up before the sun, ....Im now wondering if there is a DC battery tie in? and not including the batteries is most likely a way to keep overall cost down, people new to solar may simply not realize they need something to store the energy at night. or then again depending on the limited use a day time solar system could be all that one needs.

I’m trying to honestly think of what I would need to power (electrically)in a local or national SHTF.See, making power with an odd assortment of devices that are each making VAC, is a horrible nightmare. It takes a lot of equipment and inefficiencies to try and combine that power into a single buss, very expensive. You have to rectify each power source to DC, which is going to have losses and get it into a battery buss, then try.
We keep looking at small wind mills, small hydro-plants, small solar arrays, so long as none of them can power the entire home, then you must go DC.
DC requires much larger wiring, which is expensive. And the transmission lines can not be long, or else you again lose more power than your making.
We are looking at up to four small hydro-plants, but each site is separated by 100 yards or more. So for them, they may need to be AC just to get the power back to the house. Then to DC to be combined with the other sources.
One power source big enough to power a house, is going to be expensive.
Two of our neighbors are off-grid, they have nice setups. But expensive.
I do not know.I’m trying to honestly think of what I would need to power (electrically)in a local or national SHTF.
With a bit of planning all our needs could be supplied with a small DC system. I look at it this way, if a RV can dun everything off dc and make you comfortable I should be able to do it in my BOL. and not too expensively.
Now to be specific I am not talking about sharing the solar / wind / hydro generation system with the grid, but "switching over" the grid feed to my off grid feed during this time.
Do you still think it will be cost prohibitive?
I posted this site in its own thread, but here's a link about this guy's power plant. They live in this year round which is too rustic for me but for a BOL, this would work very well and only cost a few thousand dollars start to finish.""People might want to put up one, see if it works. Then with their next paycheck, they may buy four more," Cinnamon said"
who here has $4000.00 to spend per paycheck? LOL I can see a benefit of setting this up at my bol, With deep cycle batteries you could "backup" your bol with emergency power in the event the grid went down. Freezers, lights emergency communications etc. But I certainly would NOT pull a permit or tell the grid police I have the system installed.
nice article, I am working on the paycheck to paycheck version of solar power, a little at a time, and add devices as I have the available power.I posted this site in its own thread, but here's a link about this guy's power plant.
