How A lot Photo voltaic & Battery Capability Do You Want For Van Life? – CleanTechnica – Uplaza

I not too long ago got here throughout a terrific video from CheapRVLiving on YouTube. In it, Bob Wells goes via some issues folks want to contemplate when looking for issues like energy stations, photo voltaic turbines, and permanently-mounted photo voltaic and battery setups. Let’s first take a look at the video, adopted by a recap for folks at work and a few of my very own added ideas additional down:

Bob’s Suggestions

Earlier than I add my $.02 to the dialogue, let’s recap the suggestions from the video for individuals who can’t watch it for no matter motive. For many individuals, solar energy continues to be a seemingly magical factor, and other people with no expertise with low-voltage wiring can really feel intimidated by it. After which there’s all the watts, amps, and volts (plus watt-hours and amp-hours) that may result in confusion. However, the know-how has come a good distance since folks like me and Bob have been experimenting with it (he did his first photo voltaic setup in 2010, and I did mine that very same yr!).

However, deciding how a lot solar energy you want doesn’t should be rocket surgical procedure. Nowadays, you don’t have to know something about wiring and also you don’t want to rent an electrician to get the advantages.

The apparent first query is your price range. Everybody would like to have a giant photo voltaic array on their camper or subsequent to their tent that may run the whole lot, together with air-con and EV charging. However, a high-end photo voltaic setup can value over $10,000! So, you must begin out by understanding what you possibly can spend first, as a result of the sky’s the restrict. Bob begins off exhibiting viewers a easy 200-watt system that prices about $400. Luckily, costs have been coming down and proceed to come back down.

As a result of the sky’s the restrict, it’s actually all about getting probably the most for what you possibly can fairly spend. For folks on a smaller price range than $400 (we have now to keep in mind that Bob Wells helps lots of people who didn’t select van life), there are nonetheless choices to get a minimum of some energy to cost a cellphone, a flashlight, an electrical lantern, and different small issues. For folks on a much bigger price range, Bob recommends shopping for as a lot photo voltaic as you possibly can afford to get probably the most out of it.

The second query is house. How a lot room do you’ve got on a van’s roof? Or, should you’re taking a transportable system alongside, how a lot house do you’ve got in your rig for it? You would have the ability to afford a powerful system, however should you don’t have room to hold it alongside, it gained’t do you a bit of excellent!

A associated query is battery storage. Should you get a bunch of photo voltaic panels however no battery, you’re not going to have energy at evening or on cloudy days. Bob (very a lot rightly) recommends erring on the aspect of an excessive amount of battery over having an excessive amount of photo voltaic. In case you have a spot to place each watt-hour your panels produce in a day, you’re getting probably the most good out of these panels. In case you have an excessive amount of panel and never sufficient battery, you’re actually throwing vitality away that you just would possibly want you had later. All in all, he recommends “two to one” energy, or having twice as many watts as amp-hours.

The following query: what season will you be touring in and what climate will you be seeing? The size of the day adjustments over the yr. Deserts have much less rain and extra solar. Coastal areas can have a variety of clouds. Because of this, he recommends trying on the climate the place you’ll be spending time and dimension the system for the worst days of the yr. You’ll have to have sufficient battery to final for as many days as you anticipate not having solar, and never simply sufficient to final in a single day, and also you’ll want sufficient photo voltaic to cost these batteries up in a day or two earlier than the clouds come once more.

One broad suggestion he offers is to have a minimal of 200 watts of photo voltaic panel and a 100 amp-hour lithium battery (the setup he reveals on display). This gained’t run something like air-con, however it would give energy for necessities like LED lighting, charging up telephones and lights, and many others. 300 watts and two deep cycle batteries is healthier, and so forth.

Whereas vitality audits (taking a look at what your gadgets/home equipment use) are necessary, Bob doesn’t waste a variety of time on that. Why? As a result of no person can energy the whole lot they may ever need. There’s at all times one other creature consolation you possibly can energy! As an alternative, he recommends spending as a lot as you possibly can in your photo voltaic/battery system so that you’ll have as a lot vitality accessible as potential.

Lastly, he offers his excellent suggestion: 400 watts and two deep cycle batteries, with compromises taking place for something smaller. For RVs, he recommends a minimum of 500 watts to account for phantom attracts, however with 1000 watts to essentially be extra snug. He additionally recommends tilting the system towards the solar and following the solar (swiveling) to get extra energy out of panels at any time when potential.

In sum, take into account this stuff:

• Funds
• Area accessible
• Purchase all you possibly can afford

Including EVs To The Van Life & Tenting Combine (My $.02)

Most of Bob’s viewers is having to do issues for as cheaply as potential. Whereas YouTubers and Instagram-ers had been massive on residing in outdated vans and faculty buses, Bob’s viewers is extra about survival than glamor and clicks. Many individuals residing in vans are doing it as a result of they will’t make the ends meet on restricted retirement cash, or as a result of they’ve discovered themselves not doing properly with the form of grind it takes to achieve success as of late chasing the American dream.

Because of this, most of his movies cater to individuals who purchased an outdated work van or stay in a gas-powered automobile of some type. It’s what they may afford with out going right into a debt that they couldn’t safely service.

However, EV costs are dropping, and a few of Bob’s movies characteristic folks residing in older EVs. So, that’s the place the way forward for van life and nomadic residing is headed.

As I detailed in one other article, I’ve been experimenting with utilizing my 60 kWh EV battery to energy a campsite. This features a full kitchen (together with toaster oven, microwave, and fridge), in addition to air-con and warmth for the insulated Shiftpod tent. When you’ve got tons of battery, it’s loads simpler to energy nearly something. With used Bolts going for as little as $10,000 should you store round, it’s going to be simpler and simpler for nomads to all have an enormous battery they will go into city and cost as soon as every week when photo voltaic doesn’t lower it.

This doesn’t assist individuals who can’t afford an EV at present, clearly, so I don’t decide anybody for not driving one and residing in it. However, for individuals who can, it might be a much better setup than the options.
