Charles, what 300w panel are you using? I'm finding it difficult to put 1000 watts of 12v on the roof of a 40 foot bus. I'm using only the sides, since tilting the panels would shade any located down the middle.

didnt know wind blocked the sun, thanks for the info

they have twice the capacity, less cells is always better, cheaper is not always better.

Last I checked, the l16 has 2.1kwh of storage and the t105 has 1.5kwh

Am I wrong?

Solar is an awesome option and ive been incredibly happy with my setup. It cost money, like every thing, bit i can do it cheap. I fit 1200 watts easily on my bus with room to add 600 more very easily.

I've had a very different experience with my solar set up.

First, the cost was reasonable. I paid around $1100 for the panels, wiring and charge controller that will run everything I need it to (small refrigerator, lights, water pump, inverter for tools and kitchen stuff). Whether you're running a generator or not, a bus/RV should have a battery bank so I'll ignore that cost. After all, it'd be silly to have to start your generator to turn on the lights on the way to the bathroom at night.
I did the calculations of purchasing and running a Honda eu2000 and a cheaper Champion 2000w generator. My findings were that - as of beginning of August this summer - the solar system has already paid for itself vs buying either of those generators and fuel.

Cleaning being a problem? Nope. I've only had to wipe bird poop off once. The rain has taken care of the rest. Even when on the road driving around Texas last winter. A desert dweller may have a different experience.

Also note that battery banks should only be bulk charged at a maximum amperage that is determined by the manufacturer., then the amperage tapers off to finish charging. Because of this, running a cheap, non-inverter generator to charge batteries is a wasteful affair. The cheaper generators don't throttle down in sync with the battery charging requirements.

But the biggest, best thing about solar? Silence!
I've had the unfortunate experience of camping next to generator powered RVs a couple of times. I try to avoid the situation the best I can, but sometimes it just happens.

I should add, though, that if you do happen to have a generator it can come in handy for backup situations. This time of year we have plenty of rain and clouds. For at least one week recently it was steady clouds and I had to be conservative with my electrical usage. We made it through fine, but you may need to be watchful of the weather on the rare occasion.

yep looks like t105s have 220 at the 20 hr rate and l 16 are 380. so yes there is more storage in the 2 105s. its still a hole lot better just having 3 cells than 6. i believe you posted handy bobs blogs. its in there. to each there own. next set i will only have 6 cells, going with the big dogs. i have 4 l 16s nowhttps://www.altestore.com/store/Deep...Battery/p9704/

Here is a rational thinking. Waste all that money on a system that only returns penny on a dollar, and if bus break down, then what? Last time I checked, minimal in-frame overhaul kit costs something like $2000 for parts alone, way much more than cost of bus alone. I wouldn't hire anyone to work on my machine, never did, especially the dealers with certified logos, because I just don't trust someone else would be good enough or care for a genuine repair work. Bus will sit on a ground for few month, if not years, better just sell it for scraps.

Soon or later, component will break down, batteries will be replaced, and hails will knock out glass panel if it wasn't vandalized already by someone looking for easy money. I wouldn't put solar even if the US government gives me thousand in free money, because it just is not economically feasible.

Wow. Not my experience in the slightest.
I spent around 5k on my setup. Some people drop 2-3k on a dies genset that is loud and takes fuel to operate. If someone wants to get on my 11' roof and steal my panels for 'easy money' they can have it. But i hope to never live in a place THAT rough....

Your criticisms illustrate a lack of experience or knowledge with solar power. I hope no ones takes them seriously because they are not grounded in fact or reality.

And every single component of the solar system is easily removable, with the only exception being the brackets that attach my panel racks to the bus.

Gah, i just cant get over your extreme pessimism!!
