Good videos nipsip. A portable solution for air cooling is something I'm going to seriously look at. At a 2019 camp-out the inside of my 4m bell tent reached 40C (104F) at the apex (hot enough that any insects flying into the hot zone fell out of the air dead) and whilst I had my suitcase...

Alternative title 'Boondocker washes grundies in twintub' :LOL: My only reservation with the demonstration was the open disposal of the greywater. Certainly in the UK legislation exists on greywater disposal for prevention of pollution to aquifers and water courses, which is why all greywater...

So where do ultrasonic thumper deterrents feature in the effectiveness list? Personally, after one or more got a taste for stripping insulation from my cabling and on coming home one day to that perculiarly recognisable smell of rodent ECT and electrical shorting, I found one ultrasonic per...

In lieu of anyone stepping in with some number crunching, I did a bit more digging myself into this topic, because we're all about the solar right guys and energy is energy. Objective My focus was on water heating and application for space heating and efficiency / cost for solar PV versus...

Good article.

That would be some interesting math to calculate the precise shape. Subsequent 3D printing of the model and reflective foil vacuum-forming would be easy by comparison.

One of the cost factors to take into account with any solar installation involves cabling between the panels and either where the power is to be used and/or the battery storage bank. My question for the forum, could long cable runs be substituted by using mirrors to focus sunlight on to a...

Does anyone have the energy comparisons between heating water using photovoltaic source to power a water heater (on demand) and solar thermal to heat water direct in the panel and using some form of high volume storage to extract using a heat exchanger? Which is the more efficient and which...

Will's video on an automatic transfer switch ... many thanks johnzilla(y) for the post because I must have missed this video and a product which can grid charge dependent on battery voltage status to top-off the solar, is just the thing I've been looking for.

?IDEA! For active solar tracking, the solution to the single stress points of a pole mount would be to centre the entire array on a turntable or raised circular rail.

Interesting topic and so many videos to be found searching using 'atmospheric water condenser' or 'air well' including commercial products. Zero Mass Then there are technologies that use no power at all ... Warka Water Towers But I'm guessing you will be looking at solar to power a colder...

There is a surprising amount of solar gear on Facebook market place.

An interesting if slightly less safe application of alternative energy, which until mainstream adoption has always been realm of the Prepper. However, what these videos demonstrate could be considered post-societal breakdown survivalist skills ... take one drain pipe ... Just one question...

The formula will work for anywhere north of the equator. I'm in Hull, UK :)

1500 bucks!!!! All the sensors do is interupt the power to the pump, turning it off. Float switches are cheap as chips. Coupled with a solar panel, charge controller, battery and a good pond pump, I bet similar could be cobbled together for much less.

dougbert, thank you for sharing the evolution of your solar system. I'm just about old enough to remember those first solar cells when the silicon could only be cut in the round.

PHoganDive, I am sorry that you feel the Dark Mode option is not useful to yourself. What can I say(?) Don't use it. However, if you come across better more workable solution please do share.

Whilst it is true the best power saving will be from devices with OLED or AMOLED screens, where the pixel elements are not just rotated but switched off to create the colour black, this particular extension also has option to control brightness, which will have power saving impact with LED displays.

Minion ;) love it.

Of course there is need to reduce consumption as much as possible, because this is the only way to reduce impact on available [energy] resource. If the method of reducing consumption involves switching technologies, ie, tungsten incandescent to LED illumination, then consideration has to be...

This [SAM] really is the all you can eat nuke to crack a nut and seems just the job for roof mounted grid tie-in systems and large arrays. Fortunately, the need to calculate roof stress due to tornado down force is not something commonly experienced in the UK, although we do have some pretty...

Thank you, that simple bit of math will help a lot. Unfortunately the $73 shipping on top of the $175 cost of the charger, is a bit more than I wish to pay; however, the net cost together with specification will be a good indicator on the quality I am looking for.

Might sound too obvious, but how about applying a sheet of clear picture glass large enough to cover the crack. The new pane could be cut so that when sealed/glued along its edges, no edge obscures the silicon cell underneath.

lf like myself you are a fan of power saving on mobile devices and have Chrome, Firefox or Safari installed, there is a new browser extension that will display any website's pages as dark mode, including this forum. The following link will take you to the main website, where DARK READER can be...

A tip I have adopted from a friend, who converted a horse box into a mobile home, was to mount a blackout roller blind same size as the panel to the support frame, with the blind canvas guided through channels and whenever there is need to disconnect components or change batteries, this blind...

Greetings Energy Experts, I'm looking for recommendations for a reasonably priced smart battery charger, that can top off my battery bank of two 12V 130Ah sealed deep cycle lead acid batteries in parallel overnight when not under load. Batteries have voltage drop protection to prevent...

I have always used the following advice as means of judging the most efficient angle to the horizontal for northern hemisphere and my UK location (latitude 53 degrees): SUMMER Degrees Latitude x 0.9 - 23.5 SPRING / AUTUMN Deg. Lat. - 2.5 WINTER Deg. Lat. x 0.9 + 29.0 Simply put, summer...

Location: Hull, UK (that's 200mls north from London, hang a right at York and 40mls east, located on the estuary). My time: Currently summer so UTC+1 Experience: Mainly from researching RV and Home Battery Solar YouTube channels for reviews and recommendations. Projects: Portable 12v "in a...
