    3 Solar Panel Wiring Issues Answered:

    Net Metering Explained With Actual Data:

  2. You are not allowed to take the federal tax credit if you use old used panels. So the savings gets wiped out.

  3. Do electric companies actually pay you for extra power generated, or do they just give you credits for power you can use later?

  4. I really like your videos. Thanks for sharing!
    From what I have studied it appears optimizers in most cases are not needed and do not add to the efficiency of the solar panels. Then by adding them you increase your install cost and have more things to break. I have a rapid shutdown scenario so I bought Tigo TS4-A-2F units that each can be used for two panels so that kept my cost lower than using optimizers.
    I also am going with a Sol-ark 12k unit since I want to be able to power from the grid and have a charge controller for my 15Kwh lithium battery backup. I will not be selling power back to the utility since I don't want to hassle with all the BS required for that. Besides utilities are making it less advantageous to do that.
    I live in Southern Cali and our rates are crazy high. Usually over 35 cents per KWh. I am on a time of use program where super off peak rates are 8 cents per Kwh. I charge our electric car during these periods and can use my battery to help fill in during my peak rate times.

  5. Why wouldn't you use microinverters? I'm practically ignorant, but theoretically fairly knowledgeable. Just want to expand my knowledge before I build

  6. 25k huh. Lol. You know u can buy 20kwh batts for 6k. Panels meh. 400 used is cheap as hell. 50 bucks a panel. 1k for panels.

  7. Really great video. Love the idea at the end. Just going to put up solar at our house soon, this was very helful!

  8. You are making a mistake when explaining the return on investment. When you buy stocks you don't "waste" your initial capital, with solar after 5-10 years you are even.

  9. Great video. What would the cost be if you were to use micro-inverters, and add the cost off energy storage, aka battery? Batterys are expensive, and to get off grid, you'll need storage. For grid tied systems, I have a question, again, I would go with micro-inverters, not sold on a battery at this point, but see cost savings for energy, but big install costs. Most companies recommend systems in the 13kw, 15kw, 17kw, and state this is for annual usage, my question is "Why not install a 9kw system that easily exceeds my monthly usage would eliminate my energy bill, and would cost far less than $30k – $40k?" I don't understand why they sell on an annual basis, but electric bill is monthly, so to me cover monthly. And annual will take care of itself. Thx.

  10. Partial shading will not much affect on the production of your system because the blocked block will be by-passed by diode. the lost is just 1~5% only.

  11. Really informative. I think the only real concern with second hand panels is what kind of life expectancy they have left? Does the performance drop off at some point? I guess it's hard to get real world figures for that unless the same panel has been in production for a good long time.
