Solar plan
i read all of the posts of the solar installs and try to read everything that comes through. I didn't buy a trimetric or anything else to measure my use but some suggest matching it to the battery amp...

Some are glued together and some have plastic bits that don't like to release and be put back together. The MC4 connection terminals are weatherproof and easy to use. They are built with (+) and (-) phase differently so phase connection is hard to mess up. They also have a UV resistant jacket, as mentioned.
Westend, Thanks, I have never worked with MC4. I had this impression of light weight quirkiness or funny ends. I did notice a forum comment about people voiding their warr by cutting the mc4 on the panel.
I would definitely weigh the differences between 24V and 12V modules. There are pluses and minuses for both. FWIW, I chose to use a single 24V module because it has greater power density, is easy to install (rather than 2 x 12V), and price/watt. I may add an additional module in the future so I wired everything with that in mind. I use a Morningstar MPPT-15 controller, at present, and may just purchase another if I upgrade. I've found that the Morningstar is a good product, plenty of functionality and does everything well.
