    What is an appropriate PPA cost for a commercial installation

    What is an appropriate PPA cost for a commercial installation I'm trying to determine the appropriate PPA terms for a solar PPA for commercial installations where a company may use the power, sell it to the companies' tenants, and/or supply power to the grid. Those are 3 different rates...

    How to install solar panels on barrel roof without roof penetrations?

    No ground for ground mounting where this is and it isn't a beauty I promise you. Very shall we say, utilitarian. Anyway, still need a mounting structure.

    How to install solar panels on barrel roof without roof penetrations?

    I have a friend with an interesting problem. They have a barrel type of roof with a bitumen covering. The arc of the roof is about 38 feet and the depth of the arc is about 5 feet, it is about 100 feet long. There is a parapet on the sides that is about 3 feet high. What solar mounting...

    How do you know if you are on a secondary power network or not?

    I'm looking at helping someone with putting up solar and it seems that in the area they have a secondary power network which does not allow power to be fed back into the grid. Is there an easy way to determine if an address is on a secondary network instead of a radial network? I've looked...

    Unintended consequences of Solar that we see

    And suddenly, I want to be completely off grid even though that is not necessary (have net metering for 20 years). Cause, why should the utility get any money....

    Unintended consequences of Solar that we see

    Every large roof looks like a lost opportunity to me now. I mean, why aren't they taking advantage of free energy? It's worse when I see large commercial buildings. Like WTH are they doing wasting all that great space.... I have to bite my tongue now when I'm in the car with my wife. I...

    35,000 SF Commercial Office Building

    I think you can look at this a different way. Let's say you want to plan a 5 year payback. Multiply you annual cost and get the most value you can for that price (so 5*17.5k ~ $85k). You should be able to put a 100kw system together for that price and eliminate your bills. You should be able...

    newbie solar considerations

    you spend 500-600Eur/yr on electricity, why bother? If you must have solar, you do NOT need a 6kw system when using only 3000w/yr. Get a small growatt inverter, 6kw is more than you need. Normally I'd say get the 3kw version, but 6kw allows for future expansion and is about 700 Eur...

    Help with grid tie system

    1) Get the electric line diagrams done online. Cheap, quick, and permittable. It should not cost more than $150. 2) Get the growatt 10k inverter (as others have said). Cheap and works great. 2 strings of 10 panels each. This inverter will accept up to 4 strings. I currently have 2 strings...

    Growatt inverter grid tied stuck in stand by mode

    Yes it is. Both inverters are on grid and producing. Only problem is the clouds...

    Growatt inverter grid tied stuck in stand by mode

    Changed frequency to 60.5hz, still on grid. That was the only change that I made to my changes above, done according to Growatt engineer. They sent me firmware to manually upload as well.

    Growatt inverter grid tied stuck in stand by mode

    So, I followed the following advice and got it to work: (synchonization page, grid settings) Changed reconnection time to 5 sec, left connection time at 301 sec Increased voltage to 264.0 Increased frequency to 64.00 (frequency watt page, grid settings) Changed FreqHighDerate to 60.50hz...

    Growatt inverter grid tied stuck in stand by mode

    Yes to both. Power cycled both dc and ac power at least 3x now. It immediately goes into standby mode and never starts the power on countdown (now 301 seconds). The voltage is within range verified by voltage meter. I also saw the previous thread and tried all of those things. I was given...

    Growatt inverter grid tied stuck in stand by mode

    My solar system has 2 Growatt grid tied inverters, a 6kw and a 10kw. They have been working flawlessly for 2 months, then yesterday, the 10kw inverter (model min 10000TL-xh-us) just stays stuck in standby. No faults showing. I've tried the things mentioned on this site, power cycling...

    Enphase IQ8H Microinverter and 595W panel

    Based on my purchases there, not sure I'd call Greentech a low cost store, but never mind that. The flashfoot2 are about $15 each, you need 2-3 per panel, more in high wind zones (I had 16 for 6 large panels). Rails are about $4-5/foot ($51 for 11 feet, or $29 for 7ft), so for a single 42"...
