    brand new to forum seeking advice on quote

    First off I want to thank everyone here I have been reading posts here to help understand the process of buying solar panels and researching if its worth it. this is the quote I have gotten so far and I will get many more thanks to the tips on this forum. I'm in the Bay Area in California in Brentwood, Ca

    Was wondering what you all thought about the make and model of the inverters and optimizers and I have no shade on the roof.

    7.8KW system
    Before 30% incentive $24,900
    26 panels Hanwha Q-cell 300 watt
    Solaredge 6000 SE inverter
    Solaredge P320 optimizers each panel
    $24,900 divided by 7.8 KW comes out to $3.19 per watts
    With 30% credit should be $17,430 comes out to $2.23
    System is supposed to generate 11,000 KWH/yr which is what I use per year
    Comes with 25 year warranty on everything every part and labor and if anything goes wrong I just call and the company does everything no cost to me
    The company is also a roofing company and reviews are all good
    I pay $2300 a year right now in electricity
    So return in investment will be about 8 years
    I bought my house brand new it was an energy efficient home as far as everything such as appliances and ac/heater is energy efficient so not much I can do there
    I like the idea that after 8 years I can actually have a reduced electricity bill or close to nothing.
    Any thoughts recommendations would be great. I used PVwatts and a few resources thanks to this forum.

Are there extras required if EV is contemplated in future? Basic questions, I know, but unable to find answers in forums. Thanks.
    I'd start by setting goals about what you want to accomplish. Then getting unbiased information about ways to meet those goals from sources who do not have skin in the game and actually provide good (that is, reasonably accurate) information.

    If the goal is a lower energy bill, start by learning how to reduce consumption. Know this: conservation and use reduction are far more cost effective ways to a lower bill (but less sexy) than PV. Example: Start by simply turning stuff off. Cost == 0, payback immediate.

    After that, spend 20 bucks and get/read a copy of "Solar Power Your Home for Dummies". More than just solar, it has a lot about preliminary energy savings and conservation as well. Educate yourself before you go further.

    Suit yourself, but IMO only, getting a hired gun is one (bad) way to meet energy saving goals. To my experience, most of them are dopes who repeat what they've heard from peddlers or the media, and then puke it out to the solar ignorant, take the money and disappear. To those hired guns who are not dopes, my apologies.

    After the read, come back here and fill in some knowledge gaps. Doing so after the read will make your questions better, and thus the answers better with a lot less wasted time on your part and on the part of those willing to provide information.

    Then, still after the read and conservation efforts, and a few answers here/there, if you still think PV is a goal to pursue, run something called PVWatts. Read the help/info screens a few times, use a 10 % system loss rather than the 14 % default and make a few runs. From preliminary costing/est., figure out the most cost effective mix of PV and bought electricity that suits your needs. A 100% offset of an electric bill is rarely the most cost effective mix.

    Then, and only then, call vendors and tell them what you want. Listen to their suggestions, but if you've done your homework in some form similar as outlined above, you'll probably come up with at least as good a project as any vendor will.

    as for EV's, they are nice, and everyone sees one in their future, me too. But I' think long and hard about it. Lots of future projections, but the future isn't written yet with a lot of details yet to be even identified much less addressed or worked out yet. That con man Musk is still building toys by hand in a tent.

    Take what you want of the above. Scrap the rest.

    Welcome to the neighborhood and the forum of few(er) illusions.

    Get your own knowledge and information. Knowledge is power. After you learn that saving energy is far from rocket science, you'll know more than most so called experts. Then you can have fun listening to the nonsense they return when you ask them questions you already know the answers to. Believe me.

    I install and sell systems in that area, when getting solar for your home get something you will be happy with for the next 25 years. In order to sell solar moudles in the usa manufactures must have 25 years production generaty that's standard.
    When choosing an inverter there are diffrent types we like to install Solaredge inverters as they allow you to not be locked into number of modules, easy to add more modules in the future, great monitoring system and they are DC so no conversion is done on the roof, they are the top of the line.
    The prices I see on this post are pretty normal, we usually install solarworld or Canadian solar with solaredge and monitoring for around $2.85 a watt. If you find something like that you got a good deal. There are a lot of diffrent panels out there stick to known brands.

    I would check previous posts about prices and there are several companies listed depending on where you live

    Root around in the CSI database for some idea as to who may be doing what for how much and where for some additional pricing information.

    The more knowledgeable you get, the lower the probability is you'll get completely screwed. Go for lower initial price without more information and the odds go in the other direction.

    I doubt any of them offer a 20+ year warranty.

    PV modules typically come with a 25 year warranty on "Production"
    Inverters come with a 10 year to 25 year warranty though some are not worth much.
    The system itself is usually covered by the installer for 5 to 10 years.


    Your price difference seems pretty high, I would doubt that those are all equal systems.

    While I'm firmly in the camp of solar PV equipment (beyond some basic quality level) now being pretty much a commodity, after your set your goals as to what you want in terms of a lower electric bill, or other goals, the search becomes one of looking for an installer who has integrity and is ethical, with the ability to deliver a quality installation.

    Finding such installers is not as easy as finding quality equipment.

    Question: Do you want low buck, or most bang for your buck ? There is a big difference.

    Hi J.P.M,

    Just one of the companies that wanted to come out to give me a quote. I'm interested in the LG panels for the price right now but still learning and doing research and getting quotes.
    Understood.

    7.5 kwh system 21 Sunpower X22 360 watt panels they come with their own sunpower inverters and energy link monitoring system should produce 11,200 KWH
    $28,000 before tax credit so 3.73 before taxes after 30% tax credit comes out to $2.61 per watts at $19,600
    Why are you still considering Sunpower ? Same annual output/performance at a higher price. PV is a commodity, not a lifestyle. Buy Sunpower and help them pay for their advertising and twisted claims of superiority. Sunpower is good stuff, but no more fit for purpose than other quality PV equipment. You'll be paying pay for bragging rights. Sort of like paying extra for a garage door opener because the salesperson said it was better.

    I have also been getting similar quotes from different companies in the bay area, except for your option 1, I was quoted 26 REC 290W Panels for a 7.54 kW system. Has anyone had any experience with REC panels? Debating if a $5500 difference is worth it to stick with LG panels. After the 30% rebate and using less panels, it will make up some of that cost I suppose.
