SolarCity Says It Has Produced the World's Highest Efficiency Solar Panel

Lucas123 writes: SolarCity, one of the country's leading solar panel makers and installers, today said it has been able to create a product that has a 22.04% efficiency rating, topping its closest competitor SunPower, by about one percent. While the percentages may appear small, SolarCity said the new panels, which will go into pilot production later this month, will produce 30% to 40% more energy with the same footprint as its current panels, and they will cost no more to make.

      Who on earth would buy batteries for a solar panel installation? Just buy a grid tie inverter and pray your area has net metering and that's IT.

      Net metering is not available everywhere, and some places are scaling back. Hawaii has some of the highest electricity prices in the world (42c / kwh). So many people are installing solar, that there is a glut of electricity during the day, and the electricity company gets whipsawed at 7pm when the solar fades but the ACs are still on. Residential battery systems that could soak up even 20% of production, would shift demand by a couple hours and solve the problem.

      And no, solar panels ARE NOT cheap. If you think they are, then give me your sources.

      The cost of complete solar systems panels and batteries is offset by the capital value they add to the property, so unlike renting a power connection and burning capital as energy, it gives the home owner something to sell. So the cost of a complete system has less impact due to the retained capital value of the system (developing branding of complete systems will have a major impact in this ie powered by Tesla or say Toyota vs a cobbled together system), pretty much no different to the air-conditioning or cooking appliances they would power.

      The more this comes into practice the more rapid the shift to DC only appliances in the home this not only reducing the cost of those appliances but also the solar power system. Likely it will be cheaper to drop the mains connection than pay a connection fee and for the additional components of a home power system to allow AC into and out of the system, keeping in mind the less power the mains power system supplies and can be charged for, the higher the rental cost for that connection to the power station (interesting problems for medium and high density dwellings versus homes). Gas as energy for cooking and heating has even worse future outcomes (except for power generation due to the polluting nature of coal ie coal dies first, then oil and then gas).

      The demand for energy will continue to grow as more accessible energy allows the conservation of other resources (cheap nature water sources versus desalinated water) and more effective recycling (better recovery of resources from waste).

      That sucks. There are some companies in Ontario that let you put panels on your roof without paying. They basically lease your roof for 20 years and pay your $500 to $600 a year. It all depends on how many panels they can put on. They take care of any maintenance and even remove and reinstall the panels for no charge for no charge if you have to re-shingle the roof. After 20 years you get the system. That's because we have a feed in tariff and this is great if you can't afford a system on your own or don't want to do the paperwork. If you have your own system you have to register for a sales tax number because you are selling electricity into the grid. (You don't really need it because you are under the threshold but if you buy your own system you can get the sales tax back by registering since the sales tax is a VAT.) You are definitely better off if you can afford to buy the system yourself.

    That's crazy. I installed my own 2.5kw system myself in a few hours. Seriously. I laid it out (bread boarded) on my friends driveway and had all the pieces except the grounding rod hooked up and running in maybe 15 minutes. I guess if people are subsidizing it and the money is there, why not charge that much.

    I got an email flyer/advert today from the company that I bought my solar panels and inverter from selling panels at $0.19 per watt. Where I live, 1w of solar will generate (after system losses) $0.24 of electricity per year. Even if its a crappy panel, it will pay for itself in a few months.

    Well, a few minor things...

    In my case, I have a two story home that is far enough off the ground that I don't want to be climbing up there myself. I could, but I'd rather not fall. :)

    Installing 32 panels up there is really a multiple person job.

    I also don't have experience with wiring this type of electricity and while I could figure it out, I don't care to risk my family's safety with something that I'm clearly an amateur at.

    So yes, technically I could do it, but this is the sort of thing I'm happy to pay a professional to do. Just not stupid crazy money...

    While that is true, it won't lower it by much...

    Cutting the panel count from 32 to 28 doesn't reduce the cost by more than perhaps a few hundred dollars.

    One thing I forgot to point out, this article compares the output of these Solar City panels to SunPower, the current most efficient. That is a small margin. But compared to what Solar City currently uses, they're 30-40% more efficient. Now _that_ reduces panel count enough to lower installation cost.

    It is crucial that Solar City says they'll cost the same to produce. Although a SunPower installation involves significantly fewer panels, the panels cost so much that the savings is not all that great. But cut panel count by 1/3 while keeping panel price the same, that actually matters.

    A hundred dollars?

    Even if you cut the panel count from 32 to 16, you're only cutting $1,600 off the install cost (and even that might be high).

    I didn't have experience either. One thing you can do is do the work yourself (like running the wires), then getting an electrician to come in and do the actual connecting, then hire an inspector for $400. My electrician is about $50/hr, but the majority of that time is unskilled grunt work.
    I'm not against hiring people, but it really takes so little skill and time and $35k is more than I make in a year and honestly more than the cost of all the rest of the electricity I'll use in my life.

    That is why I think $18K to install it is beyond insane...

    I just haven't found a reasonable local company...

    As for the power itself, $35K works out to about 12 years of my power bills, but even that is too much since a 10kw system will only reduce maybe 40% of my bill.

    It is too expensive. At $25K before tax credits, it starts to make sense.

    If good panels can be had for less than $17K for the whole kit, of course the cost would come down further.

    Maybe other areas have decent competition and suppliers, if the price is lower in other places, I could understand why more people have solar.

    But according to the solar association in my city of 250,000, only 150 homes have had solar installed. I've never seen one of them.

    No one around here is doing it (well, almost no one)

    Making them on the ground isn't hard, and frankly the racks that hold the panels aren't expensive, it is getting them on the roof. :)

    We just don't have any real competition here, there aren't a half dozen companies pushing for business, so the prices aren't reasonable here.

    That installation price is extortionate, UK and Germany panel installations are a fraction of the cost.

    Lack of competition, more demand than supply and onerous red tape costs are likely the problem.

    No, you have to install the frame to hold the panel, secure it to the roof, waterproof the mounts, do some minimal wiring. There is significant per-panel labor cost.

    So if you have 2 guys doing each panel, and it takes 2.5 hours to do each panel (it doesn't, but lets say it does), and you pay them $20/hr, you're at $100 a panel.

    Fair enough, double that to $200/hr since the company has to make money.

    $3,200 for 16 panels.

    Out of $18k install costs, that still isn't much, and these new panels don't cut the panel count in half. :(

    I'm honestly not trying to be hard about this, I just don't think the cost of adding one more panel to an install makes THAT much difference.

    Regardless, I'm still hoping to hear someone suggest a company in the Dallas area that doesn't charge stupid rates.

    An installed cost of $2 per watt would get me really excited about it. The current prices of $3.50 per watt just make no sense.
