      2 Bite When I read an article about California not letting anyone build a new power plant in their state over 20 years ago. I knew that those save the whales people would flip on the switch one day an they would not come on. Remember when Enron got in trouble for the prices it was charging Californians? 40% of your electricity comes from other states or Mexico. Texas produces all it own electricity and has it's own transmission system not hooked to the rest of the country.

    I installed 96 315watt panels with optimizers and three 7.6kw solaredge inverters. I have two large houses, an office, welding shop, all fed from one meter. I have net metering with my utility. My annual production should be about 30mwh/year. Based on my usage history my solar should offset all my net energy plus about 20k miles in my Teslas. I am an electrical contractor so it took 3 guys 3 days to install the entire system. Total cost was $40k minus the 30% tax credit comes to $28k total cost. Our power rates are relatively low at $.11/kwh. So I am saving $3300.00 using solar. I paid for the system up front so the return on my investment is $3.3k / $28k = 11.8% (actually a little more considering the 20k miles in my cars). 11.8% ROI is better than most equity investments and sure beats CDs at banks!

    Breakeven is always the question people ask me. I explain that solar is an investment, like a bond which pays an annual return. My net worth doesn't decrease when I buy a 10 year U.S. Treasury note. When the bond matures, I get the principle back. The same is true for a solar system. One's net worth doesn't decrease when you buy a solar system. It increases the equity in your home by an average 4% according to Zillow and others. You recoup that money and more when you sell your house. In the mean time, the "interest" on your investment is the annual savings on your electric bills. Even if you have to take out a home equity loan to buy a solar system, the return is almost always more than the interest on the loan. It really is a no-brainer investment that most people are overlooking.

  • @dscrive
    @dscrive 5 років тому +4

    Based on some rough calculations, I determined that solar panel degradation isn't really a big deal, when your production of electricity drops below a threshold, let's say the 80%, you can just add on an extra panel for every 5 panels, so 10 panels, add 2 and you're back at roughly the same production.
    That's not taking into account the hopeful gains of efficiency and drop of prices that might make replacing the whole system affordable.

    Hi, I enjoyed watching you uTube video & especially that you included a narrative of the prices, costs & benefits. So thank you for your presentation & I will look forward to a further update on your PV system & progress in future years.
    You live in a sunny part of the USA & I reside in the UK (Colchester), at my latitude we do not receive any where near as much sunshine & the weather is cooler, more temperate & cloudier. In October of 2011 I had a 4-kwp system installed on the roof of my house & have since added a few more PV panels to squeeze 5.75 kwp through a 4-kwp inverter. I'll try & give you some maths (as I was so impressed with yours). System cost just over £12,841 in total, but I keep adding to it & tweaking it (I can't seem to help myself - lol). Included in this cost are two Immersun units, two 110v transformers & three power halvers. These help me more fully utilise the power when it's available without importing much electricity from the grid. We don't have net metering here (sob) but we do have a subsidised Feed-in-Tariff, I don't have any export meter either. The FIT income averages around £2,500 pa & it saves me about £350 pa of direct electricity costs. My system paid for itself in 4.95 years & over the 25-years of FIT it should yield an IRR of 21.6% pa. My annual electricity imports are now down to around 125 kwhs pa costing a mere £20 pa on a zero standing charge tariff. Most people don't believe this, however I have the bills & FIT statements to prove these figures. The system generates around 5,000 kwhs pa. I have a very detailed spreadsheet which auto-calculates the discounted cash-flows & income / savings budgeted & compares them to actuals. It also calculates the projected IRR, (I used to work as a cost analyst). The reason my imported electricity bill is so ridiculously low, is that I have gone mad on installing insulation: cavity wall insulation, double thickness loft insulation, triple glazed windows & I will hopefully this summer install insulation under the ground floorboards (horrible job). I also live quite an alternative type of lifestyle, so I live a green & frugal lifestyle.
    Just thought I'd show to your readers that there are benefits wherever you live in the world to trying to live a greener & more environmentally conscious way of life. I hope this comment helps someone out there.
    Regards to all,
    JohnnyK.

      Utilities are generally a regulated monopoly wherever they operate in the US. The stock is closer to a bond in terms of risk / reward profile since they have a guaranteed monopoly on their geographic market, but are regulated to a fixed pricing structure. Because of the lower risk reward curve, the stock price is driven up which minimizes the dividend as a % of stock price. In reality, while there are short-term flaws with an efficient market hypothesis, stocks are priced exactly how the individuals participating in the market determine they're worth, which means that there's no such thing as share holders getting ripped off.

    Two months ago, I had an East-West facing 3.25 kw peak solar PV system fitted that benefits from LG monocrystalline panels with solar optimizers, Solar Edge inverter and an Eddi management unit that warms up the hot water tank with surplus energy. Even though I live in Scotland and we have had a rotten summer, my average daily electricity consumption is a unit per day. This has been achieved by behaviour modification such as buying a 1 kw kettle and only running one higher rated electrical appliance at a time to keep the load within what the PV system is presently generating. Even without any financial incentives or export payements, this has future-proofed the house and will pay itself back in about a decade.

(I'm in the sthn hemi by the way). Since late Jul18 when commissioned, production to date is 9.6MWh. Est ROI is 15% (taxfree for life of system) and a payback of approx 5 years (would be less if not for restrictions on feed-in with elec co, still working on that one).

    When I first watched this video 3 weeks ago I was researching residential solar and wanted to see real world examples, and thanks in part to the excellent presentation of your very good real world results I decided to install a 6.5kW system from Momentum solar, using Hanwha Q panels and Enphase micro-inverters on my home in SE PA. Unfortunately Pennsylvania isn’t a great place for solar, but it’s not the worst...
    I got a 15 year loan on the system and if it performs at rated capacity then I will save a few bucks starting with month one, so if we ignore the loan and just look at my monthly spending the system will be “break even” from the day it’s installed. Of course that only happens if the system hits 96% rated performance, which in PA might be overly optimistic. I will follow up here once I get the system installed and have some numbers, if you are curious.

      Here’s an update on my solar system after 30 months: My 8kW system typically maxes out at about 50kWh produced on a nice sunny day, and averages a little over 1MWh per month in the sunny months (March - August) dropping down to a low of barely 400kWh in December and January. 2020 and 2021 each saw just over 9MWh of production in total for the year, and my electric costs $0.13482/kWh, so a savings of $1,213.38 for the year, for an average of $100/month. Unfortunately my monthly loan amount is $136, so *at current prices* I’m in the red $36/month until 2034, at which point the system will be paid for, and I will start saving $100/month, so another 5 years to recoup my losses and, sometime in 2039, finally start actually saving money. This is why solar doesn’t always make sense… if your location isn’t good, or if your electric rates are low, then the payback takes distressingly long.
      The “good” news is that, since the loan is fixed, if the cost of electricity goes up, then the payback happens sooner. When the cost of electricity reaches $0.1814/kWh I will break even, on monthly average, but, since my solar doesn’t usually meet 100% of my usage, my total monthly costs will still be higher than now. One way to look at my current situation is that I’m paying $36/month now for more savings in the future, how soon that future comes depends on electric rates. In the mean time, my solar system has reduced my carbon footprint, so there is also value in that.

    Great video. I used your previous ones before I got my solar system.
    I've found that the real benefits (savings) are by leveraging solar to provide cheaper energy costs than what we currently use. So just comparing it to the power purchased from the electric company doesn't do it justice. Shifting from using my whole house gas furnace and reducing the set back temp on it to using electric space heaters in the winter saves me about $35/mo. Also moving to purchasing gasoline to electric for EV is (going to) save me $360/mo in energy costs (not including net savings for maintenence) based on the marginal increase in costs (monthly finance payments) for the larger solar array I bought to pay for the extra electricity use. Which after 12 years when the finance terms (@3%interest) ends, increase my savings.
    Just examples of how solar can be leverage to save more money by redirecting expensive energy use to cheaper sources.

Really easy, Ironridge racking system on my metal shop roof, 17-18 panels per string, 2 strings per inverter, 3 Solaredge 7600 HD inverters with optimizers. Real quick and easy install. I had to rework some electrical taps in some of my breaker panels and install a large 200 amp disconnect at my meter base to meet code. Real happy with the results. I would love to get a wrecked Tesla battery pack and install an inverter to see if I could bank my own power. The net metering is a sweet deal but at some point the utilities will not be able to offer it. I wish Tesla would allow two way power flow so I could use my cars for storage. Ultimately that will be the future, all EVs plugged in all the time as a sink and source for the grid.

    If you do not want solar panels, use water and wind. Use a wind turbine, make it yourself or buy it. Use the stream of a river if you are fortunate to have this behind your garden. Make yourself some propeller that's connected to a motor. Make it waterproof, you'll have always some energy to charge batteries. You have a roof, when it rains the rains goers somewhere, isn't? make a propeller connected to a motor once again, you'll charge your batteries as well when it rains. So, a wind turbine and a propeller that turns by water. There will be wind even at night, your batteries will be charging during the night. Just a thought. Something I'm making right now.

I used Sunpower 327w (21 of them) It took 5 days to install working 3 hours per day. The panels cost 31 cents per watt, solaredge power optimizers $60 per and inverter was $850. My entire system with me doing 100% of work was $5400. Once again no rebates or tax credits. SInce Dec 13, 2018 to Mar 12, 2019 I have generated 1.4mwh. Worst time of year, rainy, cloudy. My payback should be 5 years at 10c per kw for electric here. Even on a cloudy day my power coming from the gris is zero. I also bought the sense monitoring system so have a real time reading of what I use. Since I do not have it registered yet, I feed the grid on sunny days.
    I got commercial grade panels that were used 3 years. They are so cool as they generate 60 volts. Optimizers regulate that so each string puts out 390 volts off the roof. Wiring is very small and each panel is monitored. I can see the production per day per panel. I was in Cozumel and checked on production and could see if it was cloudy or not based on seeing the power of each panel. There is a shady area on 3 of the panels. You can see the shade effect on a sunny day but they produce almost the same on each panel on a cloudy day.

After a year of operation my electric bill increased by 20%. This is taking into account the 15 years loan payment to pay for the system.Two factors that partially contributed to this increase. SECO, utility in Lake County Florida, pay whole sale price for any surplus kwh generated from my solar system and when I need it in the same evening I pay the retail price.

    Went online with my Solar City 7.8kW grid tie string inverter system July 1, 2015. It has given me a 70% of use return over its life so far. I had just moved to this location and it was an 'All Electric Home'. I bid low on the initial look, not really wanting all electric. We got the house and 2.3 acres for $90K under asking. I retired about a year later and paid for the system with a bonus I got when retiring. The residence will get converted to a heat pump with 90%+ propane backup and propane water heater and range. We are at about $.124 per kWh now, were at about $.113 when we started. We net differently in Colorado, it is on a yearly record of use/generation. We can make up to 125% of our yearly use and get paid back at the retail rate, any generation of over 125% that gets sent back to the grid only makes wholesale reimbursement. I like it. The utility here, United Power, is currently going to a time of day pricing scheme now that they have smart meters everywhere. They are not making solar customers go to this scheme at this time, thank goodness. I am considering a second system on my shop out back as I am now retired and am building a home business. I have a separate meter on the shop, so I can get the same deal on 125%, the up front advantages aren't as high as they were back then, but the cost of solar has gone way down. I am going to start with 12X 72 cell panels on an E/W tracker with N/S adjustment manually once a month or so, going to use the Enphase grid tie microinverters. The shop is used for welding and woodworking and has R38 walls and roof. I have installed a Modine 92% 110K Btu propane unit heater and will put in a heat pump with an evaporative cooler to cool the condenser in very hot weather. It gets down to single digit humidity here in the hotter months of the year. I am making the second system very expandable so if I make very much more than the 125%, I will start using some of the high sun power to heat water and store & use during nighttime in the colder parts of the year. My rooftop system makes the most power in spring and fall probably because of the roof angle, also the high temps of summer combine with the sun angle to make fall - winter - spring the money times of the year. Cold rainy day yesterday 11% of use, not really that bad. Temps were 31° low 44° high, resistance heating in the house - space heating and hot water. House is Brick with 2x6 R32 walls and ceiling. We are about 45 miles NE of metro Denver. We have sun here a LOT. Solar has been good to me and I am going to continue to expand my use of it. It's not about the money entirely, it's about common sense. Michael from Colorado.

  • @ChickensAndGardening
    @ChickensAndGardening 5 років тому +2

    Some numbers that people may find useful: we just installed solar in eastern Massachusetts. $34K for 32 panels @ 325 watts each (10.4 Kw). We expect to get about $11K back on our taxes in 2020, and are borrowing $23K in home equity to finance the rest. The payoff time is about 7.5 years. The sunlight is not as good as in a southwestern city, and we may take down a tree to increase the power (would be helpful for our garden as well). The system won't power the house if the grid goes down. The only way to actually be off-grid is to install a house battery such as Tesla, and then we could almost kiss the power company goodbye. However it's another $15K that we can't afford at present; first we have to pay for the current system, so maybe in 4-5 years as prices come down it'll be worthwhile.
    We're told solar adds value to the home. That was not always true; years ago, solar was a liability; people worried it would make roof repair and replacement more expensive. It does indeed, so if your roof is within 5 years of needing replacement, you should go ahead and do it, and then it will last roughly as long as the panels, i.e. 20-25 years.
    I don't actually recommend going solar unless you're an environmental extremist (like my wife). I like my 20 MPG minivan and my fossil-fuel-powered home just fine. Energy prices are historically low right now and gasoline for example costs about the same as it did in 1970, when adjusted for inflation. Natural gas is dirt cheap and is quickly replacing coal in power plants.
    Anyway, it's certainly better to have solar than not to have it. Once it's paid for itself, we'll be very glad to have done it in 2019 while the federal credit was still 30%. It's going down to 26% in 2020, then 22% in 2021. But panel prices are dropping, too, so possibly will balance out. What doesn't seem to drop very fast is the installation price, which is 90% labor. Luckily there are lots of companies competing in this space, and they have it down to a fine art -- it took them about a day and a half to do ours, start to finish, and that included de-icing the roof on a chilly December day. For fewer panels and less challenging weather conditions, it should take 3-4 guys one long day.
    In 20 years, who knows what energy innovations will have come. Probably panels (if we even still call them that) will be far more efficient, far cheaper, maybe will just be incorporated into the average roof as Tesla's doing now with their expensive but gorgeous "stealth" solar roofing. Probably batteries will also be far better and cheaper. It's also possible that someone will invent a miniature fusion generator; Lockheed and other companies are hard at work trying to come up with such a thing, to enable aircraft to stay aloft for months at a time. But that tech does not exist yet. For now, the best production technology is what you can get installed, and expect a payoff of 5-7 years depending how much and how many.

    Great 8-year review.
    You might increase your energy consumption during solar production hours by using a heat pump water heater (which will decrease your water heating energy).
    In addition, these usually have a heating element. If you connect this to an energy diverter, then some diverters will allow you to increase the level of energy consumption from energy generated. In this way you could increase the percentage of energy when generating more energy.
    Also, keep in mind that this is the last year of a 30% Federal tax credit. So, if you are increasing the size of your system, this might be a good year to do it.

      Dana Putnam I rather not get involved with all that plumbing. Your idea is great for keeping the solar panel’s work temperature a bit lower, but if you think about it, most solar systems in the northern hemisphere overproduce energy in the summer, and they produce less energy in the winter due to the angle of the solar resource. In other words, despite the additional summer heat, solar panels manage just fine.
      In addition, keep in mind that solar panel costs probably will increase due to the additional complexity of the internal water tubing required.
      Today I can find reasonably good quality solar panels for around $0.50 per watt.
      I prefer the system I suggested: few solar panels, some wires, a hot water heat pump, plus an energy diverter.
      Moreover, since the time I wrote this, I learned that myEnergi makes a diverter called the Eddi which has the ability to control a hot water heat pump directly with the addition of an sense board.
      This allows for possibly the greatest efficiency in terms of energy self consumption from solar panels.

      Yeah I get that. This guy also has a sprinkler on a timer to keep the dust from blocking the light.
      Of course you know that heat causes more electric resistance so the low volume pump is more than free. Here in California the utility has to buy back the electricity from its solar clients. So the more you make the lower your bill because you sell back what your not using.
      I don’t know but I would guess keeping the temp down may increase longevity (expansion contraction on crystalline (brittle ) ) substrate causes fracturing .
      Electrical resistance can displace + / - p junctions and string links lowering overall capacity.of current.

    • @ek9772
      @ek9772 4 роки тому

      Dana Putnam most systems have more panels than the rated inverter size. Therefore, even if one is paid to produce, there is a limit to how much the grid will buy. The limit is the size of the rated inverter, and then to top it off, there is curtailment, and this applies, particularly, to California.
      Therefore, I believe setting a roof solar system to maximize self consumption of produced solar energy is the best that can be accomplished. At some point, all grid operators will pay less for energy produced than for energy sold to consumers. Therefore, feed-in-tariff schemes will become less valuable as more consumers install solar roofs. In fact, the current evolution of things in most countries is to transition from FIT to net metering.
      The best that a humble consumer can do is to attempt to produce energy at the lowest possible cost and consume as much as possible of the produced energy. This can best be done by following the old adage of K.I.S.S.

      #1 thing to consider before installing a solar array. Is the price of my electricity more than around 18 cents per Kwh and do I get enough unobstructed sunlight seasonally? This can make all the difference in the world.
      I thought I might just add my most helpful advice in what I learned about solar panel installation. A string inverter is where all the panels are hooked up in series or parallel, and the major drawback is you never know what the input of the individual panels is, and the least of these individual panels output is what your overall output is going to be. I can get more technical, but trust me on this point. Microinverters, meaning that each individual panel has its own inverter allows you to get voltage from each panel, and the ancillary benefit is that you can monitor them separately and/or together as a unit. This may sound like a small difference, but trust me it's not. If a string inverter strokes out you are done. If a microinverter shoots the shit, you are just out that single panel.
      I am not a promoter of Enphase, but I pondered this question many times. Do I want all the benefits of microinverters and pay 20% more, or do I want the limitations and catastrophic failure potential of a string inverter? I would go as far as to say get 20% fewer panels and go for the microinverters if you can't afford more.
      About batteries. For the commercial customer, they don't make economic sense unless you are off-grid as of Feb 23, 2019. This may change very soon. even in the next couple of years. And if you are super handy with electrical stuff, you can buy second-hand 2170 lithium-ion batteries on eBay or someplace and build your own battery affordably. If money is no issue, then the only advantage batteries have is uninterrupted power service during power outages.
      I look forward to the day batteries make economic sense, because then we are off to the races with energy independence.

      @@rnegoro1 If your question is if the battery is unnecessary to the operation of the solar panel array, absolutely yes. You do not need a battery for a solar panel array. The major advantage if you DO decide to have a battery is if there is a storm, and everyone in your neighborhood has no power, you will have a battery back up. The other potential advantage is when the sun goes down, during the early evening, power rates are higher. A battery could offset or mitigate some of that cost. The problem is the battery as of today, Feb 24, 2019, the battery may only last 10 years and will cost 10k (on average). So in those terms, it doesn't make economic sense. Is that helpful?

      To the best of my knowledge, and research, the materials used in solar and wind turbines are basically removed from the economy, they cannot be reclaimed. That's the main reason I am against them and in favour of nuclear. Also, I live in the UK where neither will ever amount to much, and to produce enough energy to cope with today's demands would require covering 25% of our land area with panels/turbines. And guess what? When we most need the energy, at night and winter, coal and nuclear are the only options.
      Something else Two Bit da Vinci doesn't tell you, is that current cells or turbines will produce less energy over their working lives than it took to manufacture them. As a point of fact, the British government has removed the facility for selling your energy back to the grid which used to offset the installation price. Now, any excess to your needs goes into the grid for no recompense.

The electricity is much more expensive (double or even triple price) in peak hours (usually from 5:00pm to 10:00pm) when your solar panels have little output. 2. Monthly charges for NEM users. So even if you do not use any energy from the grid, you still have to pay about $20(YMMV) bucks as long as you connect to the grid in CA. 3. No more tax credit. So now it takes even longer than before to break even for you initial investment. Solar is good, but not as cheap as you imagine.

The only thing I would respectively have a different opinion on is, I think that solar panels are a much better as an investment than suggested at 6:00.
    In my view comparing it to the Nasdaq (or the stock market) is not a fair comparison as it is much risker than solar panels and returns vary significantly even over 8 year periods. For the period in question the Nasdaq performed better but over other periods the Nasdaq has performed worse (Someone who invested over a 8 year period in 2005 would have lost money (the Nasdaq declined from ($42.28) 2nd December 2005 to ($38.55)13th December 2013. The value of solar panels also does not experience sharp drops of 1/3 to 1/2 in short periods of time.
    The level of risk with Solar Panels is much more like US government bonds or Bank savings accounts. (I.e. a steady consistent return). It compares favourably to them in the current low interest rate environment (if you live somewhere sunny like California). Maybe you could compare them in a future video. As an investment, solar panels also offer asset class diversification, as they are an independent asset class. The output from the solar panels does not correlate with returns from the stock market, bonds, or housing, reducing risk in a portfolio. The Solar Panels may also add to the overall value of the house.
    I live in Northern England and would love to have solar payback after 5 years, but unfortunately the payback time if I am at home all day is 18 years. If I am out until 4 most days there is no pay back (i.e. its longer than the warranty term of 25 years), so its very much location dependant.
