Hi Folks: I have a Solar Powered RV Trailer that was my Covid project. I did ask several questions here on this forum and you can see them on my profile. I learned a lot and actually used the RV trailer just once and I'm selling it now so I can move on to other projects.. It has 3 QCell 315...

Thanks for the correction. You went to a higher level of detail that I ever could.

Here is a thread on it #30865 https://diysolarforum.com/threads/why-not-cigs.30865/ but they are discussing the flexible models of CIGS, not this glass on glass module.

I have the same problem with shading and did extensive research and like everybody says, the best approach is the chainsaw approach. But besides that, some other tips: - you want the half cut modules, so you reduce the impact of shade on the panel. A normal 60/72 cell panel is divided in three...

A frameless double sided glass would be ideal for you. They are hard to find, but for example First solar panels are frameless.

I'm not sure if you are still looking for tips on that as it has been a month, but https://kinectsolar.com/ does sells weird quantities, specially if you pick panels that they only have a few. I did order several parts and panels from them and their prices are very good, as they deal with...

Found this . It may be helpful. https://www.primalsurvivor.net/florida-off-grid-laws/

I believe Will Prose the guy that creates all the YouTube videos explicitly says that he is not available for individual consultation, so your best bet is to explain your situation and if it's interesting he may jump in the conversation.

I have no experience with KNX, so I can't comment on how they implemented security, but I do have experience in cryptography so I want to comment on your statement about the private key. A solid security implementation would work the same way as SSL/TLS, where only the certificate signer has the...

I wasn't aware of Knx, so I learned something new. I think this is the answer to your question

I would check your inverter manual, but here what it could mean https://en.m.wikipedia.org/wiki/Potential-induced_degradation

As you are asking for ideas, here is an out of box idea for you: solindra solar panels. Their shape may give you more flexibility where to put the panels and they are also unidirectional what may give you a best harvest. Here a link With a guy talking about it.

No, your theory is not correct. The way I think of electricity to make it simpler is to think it is plumbing and solar panels/cells are water pumps. If a pump is working is adding water and pressure to the line (voltage). If it is not working it is a source of friction that reduces voltage (that...

As somebody that did a DIY install on my roof, I would strongly suggest the pergola. It is closer to the ground so easier to install and the maintenance is so much easier. After install you need to worry about keeping the panels clean, debris and critters under the panels, failed microinverters...
