1. SunPower makes solar panels that are not catastrophically affected by partial shading.
2. The cost of solar is prohibitively expensive, because people believe stuff like this.
   You don't need some professional assessment of your home for all this nonsense.
   Go to any home supply store, buy a cheepish solar panel or two, an inverter and a battery or two.
   
   The first stuff you buy will be cheap and it's not going to replace your grid tie, but it will get you started making some energy. Plug some smaller stuff into this mini power station, and start reducing the amount of energy you are taking from the grid.
   Little by little, you can add a panel here, a battery there. Start small, and keep it DIY, and withing a handful of years, you will have:
   a. reduced the amount of power you consume, by extension of learning more about solar and how much energy you NEED, not what you already USE.
   b. kept the cost of switching over low, by doing little by little, as you had budget for it.
   
   You are going to run into problems, things wont always work out of the box, but you will KNOW how your system works, why it works, and how to fix it, should things need fixing.
3. the new unbreakable glass shingles replace the whole roof....no panels.
   battery wall...5500 if you buy tesla....inverters included
   electric car.....really easy to make one with a range of 60 miles
   the electric companies already are passing anti solar laws....so everyone is going to have to go off grid...just the way it is
4. Your rate of return is not comparable with other regions.. In my region the rate of return is more like 10-12%. That was a very discouraging statement for your viewers..
5. If you buy the TESLA POWERWALL 2 , I think you will be totally fine and even go totally offgrid , it just depends on how many batteries you choose to buy...
   Its a 14kWh battery+inverter and cost $5500
6. but where is your energy storage?
7. Make my electric garden tractor, and it could be charged by solar, zero pollution
   Brian Edmond
   2hrs cutting approx 2 acres or 8-10 hrs pulling trailer on a charge
   Converting to battery power is a great idea for a garden tractor I converted one 15yrs ago, I used the 3 separate motor design and it is still cutting grass on a daily basis, it is amazing how it never breaks down and needs almost no maintenance, I renew the batteries every 7 yrs I am just on my 3rd set now, my design will cut up to 2 acres on a 50cent charge there are no belts or pulleys and no oil on the entire tractor, it can pull a trailer for about 8hrs on a charge, because battery run time is the most important aspect of most conversions I paid particular attention to the most efficient design, I used 3 separate small motors one for the drive with electronic speed control and two smaller with a cutter blade mounted on the shaft of each cutter motor ,total amperage when cutting grass is approx 40amps, (2000watts) this design only uses the battery power req to do the job, very little wasted battery power, it uses magnetic breaking of both tractor and cutter blades and automatically applies parking brake when you stop or get off the seat, an amazing tractor. electrictractor.net

8. going green is the ultimate investment. we have to begin to look at this not so much as an individual financial investment but rather as an investment in life. or the future quality of life. it is true, that most of us will not see the rewards of cleaning up our planet, but our children and their children will. if only our parents and their parents knew and cared as much about their eco system, we might not be in this mess.
9. about 2 minutes in you mention shading as a problem.
   
   It is for a conventional string inverter, but if you pay more for a PV optimizer or MPPT microinverters, they can operate per-panel and operate in worse weather conditions, colder/cloudy weather, odd angles, flat orientation, etc.
   
   (a device modulates the power coming from each panel separately, so the panel can handle shading and operate closer to dusk and dawn periods. Also with PV and microinverters, you can add east/west facing panels on the roof. In terms of cost to return ... depends on if you need an island inverter to run off-grid, since that's a bigger problem, plus the battery tech is quite immature for home use, i.e. 10-20kw battery systems for off-grid i.e. 3 tesla powerwalls for a full day of usage. Enphase / Solaredge are popular micro / pv opt companies
10. Translation: OTHER electric customers and taxpayers are SUBSIDIZING YOUR system. WE are getting RIPPED OFF!
11. Good info, thanks. Actually you are not off the grid as you are still tied in. The other thing is if the grid goes down, the power from the panels are disconnected as to not shock any workmen. At night you will now be drawing off of the grid for power. To really be off the grid power you will need to have a battery storage system, and that can be really expensive. Currently, I'm working on a expandable off the grid starter 1.2kv system with 8 golf car batteries running at 48v. With a 50 amp mppt controller and 4000w inverter it can provide my basic power needs (no AC, I rarely use it any way). Estimated cost is $4500. Being in So Cal, I'll get as much sunshine as you do in Texas. As more money becomes available I plan to expand to the next level by adding two more 320 watt panels and another 8 more batteries. I will be using the same mppt controller and inverter. Following that, I'll be working on a tracking system.
12. Your local energy cost must be low. In the north east the ROI is about 6-8 years. this was a good video
13. Should have moved the exhaust tube. How do you get 5% return. Should be higher. You make is sound so complicated but all you had to do was sign the contract and write a check. Your solar contractor should have done the rest. Congrats on doing your part to help prevent global warming!
14. I'm amazed that rebates paid for 2/3's of the installation. Good for Texas for investing in solar.
15. Very informative, anyone contemplating installing solar panels should watch this first. Nice job.
16. I may be blinded by the brilliance of your video but couldn't find the promised spreadsheet.
17. Thanks for explaining the ups and downs 👍
18. ground mount is better
19. thank u 4 nice video
    but u didnt mention the snow effect
    coz u live in cold country
    this is mean that in winter season u will go up to ur roof many times to remove the snow!!
    also am afraid that snow balls in the storm could break the solar panel
    did u think about these ?
20. I liked your summary. I'm honestly trying not to be critical....
    But you don't sound very do-it-yourselfy.
    I did a $8K home system. It was simple and straight forward.
    You can't lift a few dozen 60 pound panel onto your roof without an elevator?
    "Carrying panels [from one part of your flat roof to the other]"? Are you kidding?
    It might have taken you a week to do it yourself, but you'd have so much more fun, and exercise
    I assume you don't do much home-wiring/repairs.
