Off Grid Solar Shed: Is This The Cheapest Solar Package On The Market?
Вставка
- Опубліковано 3 лип 2024
- I search for affordable off-grid solar power in my shed. Rather than taking the easy route with a conventional AC mains connection, I went on a late-night online adventure and stumbled upon a promising package on Banggood. This budget-friendly solution includes a 6kW inverter, a solar charge controller, and an 18V 18W solar panel, all for under £100 (approximately $120). Originally designed for camping and travel, this setup seemed perfect for charging the batteries for my Ryobi electric lawnmower, strimmer, and hedge cutter. To store the solar panel's energy, a 12V battery was required, but I had a suitable one on hand. Join me to find out if this cost-effective off-grid package is any good.

I started with a 30 watt solar panel, one of those $10 charge controllers, a battery out of my riding lawnmower and a 400 watt inverter from the auto part store. And I was loving it !
Of course my system is now 20x larger. Fun and useful stuff. Take Care.........
A 120W panel had just been delivered, so I guess like you, my system will just grow and grow. Thanks for sharing the info.
I have a very similar set up in my shed . I have a 100 watt solar panel charging a 110 AH battery and a 1 Kw inverter.Originally I was trying to run everything from the inverter but found the inverter drew a lot of current and got warm which of course is wasteful. This caused the battery to discharge in a short period. So I reworked most of the system. I took the 240v 75 watt fluorescent tube lights out replaced them with strips of 12v led lights running at about 20 watts. Bought a new radio that runs from a usb socket rather than my old mains powered one. Some of my power tools have been replaced with rechargeable ones that have been adapted to plug into my 12 volt system. Hey presto it all works fine and dandy. I never have to charge from the main and seldom run a cable out from the house unless I have to have electric heating in the shed . I am considering a Diesel heater at some point. Great video Keep up the good work .. FDO
I've just got my hands on a 120W panel, so the upgrades have already started. Thanks for sharing your experience.
Nice video. Great application for a small solar system. Maybe a bigger solar array would enable you to power all the shed! Listening to the load requirements I doubt you could manage through the winter months on just solar.
Yes, I totally agree. I've the calcs and know what I need and you're right, it will need a Solar ATS for auto switch over to mains when needed. Or maybe a generator. Who knows. These solar off grid projects have great value and are fun.
100ah battery = to 1200watts x50% depth of discharge recommended so only 600ah usable. your solar panel is 18watts so 600watts / 18watts = 33 hours of charging in peak sun if that is 100 percent efficient
Exactly. This is fine for occasional charging of power tool batteries, but not much else. There's some big upgrades coming soon when the weather get better.
with this solar panel you need probably two weeks 10h full sunny days to charge this battery :(( I think 100W solar panel is the minimum
In raw terms you're spot on. But my application only needs the battery and inverter to charge the tool batteries a few times a month. In the 3 months I've been using this, it's never been short of power. But this has very sporadic power demands and I was looking for a super cheap solution. And as you point out, you have to choose the correct components for your particular application. Thanks for your feedback.
