Hi My name is Kris. I just purchased the Renogy 100 Watts 12 Volts Monocrystalline Solar Bundle Kit with LCD controller. I will install it on my small barn. Might have more question later but here are two first ones. Where should I place the panels? Please see the image below and let me know the number of roof section. The black rectangular on second image shows how my shed is located. Second question is do I need to mount the panels off the roof or they can lay down on the roof? Thank You   |

Hello Kris,
I would recommend mounting the panel directly on the roof and mounting it on option 3. This will make the installation much easier and will keep wire length from the solar panel to the controller to a minimum.
O.C

Hello Kris, I would recommend mounting the panel directly on the roof and mounting it on option 3. This will make the installation much easier and will keep wire length from the solar panel to the controller to a minimum. O.C In support of O.C's recommendation, I would add that area 3 in your diagram appears to be at the most optimal solar angle for the panel, followed by area 1 and then by area 2. |

Thanks guys for the reply. I have already purchased the battery now I'm just waiting for the kit to arrive. Cannot wait to put my hands on it.

Another question. I want to put a load center in my circuit. Will connect DC to AC converter and after load center. What wire size should I use between converter and load center?

Hello Kris,
I would recommend using the largest gauge wire the DC to AC converter and load center have in common.

Another one. Can I put my battery in the loft in my shed and the PWM controller on the main level? I would like to save space by placing the battery on second level. But at the same time I think somebody have mention somewhere that it is better to keep the PWM as close to the solar panel as possible. If I mount the PWM on the main level then the distance between them will be about 10ft. If I mount it in the loft then it will be about 4ft. What do you guys recommend?  |

If it were me, I would keep the PWM as close to the battery and solar panel as possible. Shorter cables = less loss = more juice. So: Both on the second level.
Having said that, a 10 foot run between the solar panels and the controller is not terrible. In fact, the MC4 adapter kit that comes with the Renogy 100 Watt starter kit is 20 feet long. Putting the PWM on the main level should work fine too.

I bought the bundle kit so MC4 adapter kit is only about 9". I have to supply the rest of the length. My other concern it how often I will have to get to the controller? Once I set up the kit I do not plan to upgrade it unless I will get addicted to it :-)

Hello Kris,
I would recommend having the charge controller and battery as close as possible to limit voltage loss. After you set up the system it should continue to work normally but I would recommend checking the system once a month to verify.
