First, in order to have a home plant that allows you to be net-indipendent it takes a very good quality which still has a very high cost in italy where i write from the minimum for a 50 sqmeter flat is — euros and, unless you have cash, you are forced to ask for a loan that lasts 10 years at least. Third, the governments and energy suppliers that govern the network are increasing the renewable quota in the electricity mix but they are raising the cost in the bill.
The result is that in Italy, and as far as i have been said from some friend of mine living in england and in spain, a new market is flourishing: people selling used PV plants and buying them second-hand in order to reduce the initial cost. Let alone this point, i believe this is a very nice and balanced article, one of the best i have ever read on the theme.
Thumbs up! Even though California has experienced drought conditions, rain shortages, and reduced levels of water in rivers and reservoirs, California state energy officials are not panicking since energy providers diversify their power sources.
Change your light bulbs with energy saving, there are many different types the choice is yours. Source says that terawatts is times the world consumption. That would put the world consumption to a mere 6 GW. The world consumption in was terawatts!! World energy outlook We want to install solar system in Acapulco Mexico. Which type of panel is better to install there, mono or poly crystaline? I would start the solar process by getting 3 quotes. Dwayne, Did you get the info that you needed for solar at your home?
I can help you make the switch to solar electricity. I work with homeowners with similar circumstances here in San Diego and will most likely be able to resolve all of your concerns. Best, Ben.
We hope to be a helpful source, but just a friendly reminder that copy and paste could be construed as playgarism. Good luck on your project and Happy Citing! I like very fact and detail it gives. Mainly because I am concerned on global warming and I also believe not enough is being done about global warming at all. Thank you so much this helped me with a school project that i only had two days to do.
You saved my weekend thanks again!!!!! This helped me with my solar energy report for science class. I was kind of running out of ideas on what to write and legitimate seeming websites for it all. I just had them installed monthd ago. Now I am starting to wonder if it was worth it. The amount you pay for the monthly solar panel bills. Then also You will still have to pay your electric bill.
Sometimes not even that. In 2, there is no amount of time given. It gives 20,x as much energu to power the whole world for how long? How safe is the system? Are there any long term concerns with EMF?

Upstate Dad February 21, , am. New panels will of course be more efficient and you would have a smaller array to produce the same amount of power. No maintenance, no moving parts. They are beautiful in their simplicity. Lily February 7, , pm. Despite the stereotype, there is sunlight in Seattle sorta and one side of our house gets a ridiculous amount of sunlight just blasting down on it every summer.
We have considered solar panels before for our 3 story townhome. I believe installation would cost as much as we will save in energy savings if we use it for years. Thanks for doing the research : Please keep us updated! Another Reader February 7, , pm.
The Best Place for Harvesting Solar Energy Is Not Where I Expected It to Be
Not good enough to make me get out my check book. A neighbor a couple of blocks away works for Tesla, and he recently got a Tesla roof installed. I have seen the Solar City folks out a couple of times, so they are probably still working out the glitches. One of my ideas for more cost effectiveness is if these systems became foolproof consumer products.
It would have a single volt extension cord that you plug into any dryer or range plug, or into the same circuit that your electric car charger in the garage uses, which presumably everybody will soon have. THAT would be a good way to boost solar adoption. Another Reader February 8, , pm. Good luck talking the utility companies into that. Foolproof when you are dealing with electricity would be defined as impossible to defeat safeguards. The liability issues would probably make it DOA. The glass shingles look like, well, glass and appear very fragile. Tesla claims they are very strong and resistant to hail and wind damage.
Not a lot of hail or high wind here, but it will be interesting to watch how the roof performs. Greg K. February 9, , pm. Bakari Kafele February 12, , am. In MMMs idea above, it would be a stand alone system, which would mean the utility company had no say in the matter. Just like you can get a solar power pack to plug your phone or laptop in right now.
It would be a bigger version of that, that just charged your car or ran the dryer, off grid. Of course, one could do that today, it just takes slightly more work and planning to design and build than a kit. Nice Joy February 19, , pm. That is what I want to do. Run my air conditioner with solar.
My bill will go up when I connect solar to utility company even if I make more KW than used…. This is the sad story from Arizona. TomTX February 18, , pm. The Tesla shingles are tempered glass, and pass the highest standard for roof impact. Tougher than tile or slate. RobDiesel March 2, , am. Interestingly, a company about 7 years ago was working on something that was easily digestable for consumers. The point was an easily transportable panel you could even hook up on your balcony if you rented an apartment etc. Another point people miss with solar panels on the roof is that they shade the roof, keeping the attic cooler.
This matters in places like AZ, TX etc. Cooling is a huge part of electricity cost for many people so keeping that cost down is a benefit too. Plus, a shaded roof lasts longer. It is a lot more cost effective to do it yourself. I purchased panels, inverters, and racks from ML Solar, right next to you in Campbell 60 miles from me, so I drove down rather than pay shipping. CoreyH February 7, , pm. Our DIY system is also Solaredge and has been in service for about one year now. With two electric clown cars, it really makes sense for us.
By going DIY we were able to install the same size system 7. Our returns as you described well are more than monetary, but the payback time will be around 63 months. Nice work Corey! People need to have at least a vague idea of the materials and labor involved, so they can judge what is a reasonable price to pay for something.
Solar is cheap and easy — the regulations, fees, and fussy building permit rules are the biggest hurdle now, and I want to see those drastically trimmed back. Tako February 7, , pm. Very cool project MMM! It sure looks like it! Really cool that you know someone in the industry to explain it all. Most people would be held hostage to a contractor or company to do it all for them. KMB February 7, , pm. How much does the panel output decline over time?
How long does the inverter last and does its performance decline? Cliff February 7, , pm. The decline is usually expressed as 0. See the panel specs for the panel of interest. Similarly, inverter specs cite a 12 year warranty. I have not heard of a similar decline in performance. Chris Urbaniak February 7, , pm. Does the snow melt off due to excess heat from the panels, or does it need to be cleared manually?
How do the panels hold up to inclement weather such as hail? I assume that you would want to have a reasonably new roof under the panels to avoid having to re-install them when the roof needs replacing; is that a correct assumption? Check out YouTube for videos of hail impact tests. If your roof is less than 5 years old, an array will shield your shingles from hail, driving rain and UV. Nebin February 8, , am. We installed solar on our degree metal roof last year. We previously had problems with ice sheets that would shoot off and put bystanders in danger. The panels do not melt the snow, but seem to be advantageously working as snow and ice-guards.
Interestingly we have noticed that the light passes right through the snow and we still get power. On a bright day it still seems to run just about full generation. But maybe I could do it on our separate low-pitch garage…. Sheryl Highsmith February 8, , pm. While the snow will definitely melt on its own, my husband makes a hobby of clearing it off with a ladder and a very long window-washing apparatus. I imagine his snow-removal activities get the panels back into action hours earlier than Mother Nature would have done. Our panels have held up perfectly in even the most extreme hail.
In fact, our roof was damaged to the point of needing replacement by a hail storm just a couple of years after the panels were installed. We took that opportunity to have another seven panels added when they went back up, since we had just gotten our electric car and needed more power. Bohemiana February 7, , pm. You have a lot of solar needs with multiple facilities and autos using the juice. We are just a middle-aged couple working from home in a small house. Mrs PoP February 7, , pm.
Welcome to the solar world, Pete! I really think this is the future, but we need to keep advocating for them in some areas because power companies are sometimes actively hostile towards residential solar and laws should change and open up to make it an even smarter investment for people and the environment. Adam February 7, , pm. From there FAQ, they want permanent internet access for the Powerwall.
Which really makes it viable for on-the-grid locations. I really like the idea of maintenance-free batteries, though. Which is what the Powerwall is. However, the one company that makes them in the US, filed for bankruptcy last year. Not enough buyers. Which is a shame, as it was perfect for home setups. The weight kept it from being a player in any other market.
So snow could be easily cleared, replacements easily setup, etc. There are plenty of offgrid options, and have been since long long before Tesla even existed.
In between the extremes of a powerwall and salt-water is the good old standard 8D lead acid battery, the same kind semi-trucks use. Cheap, reliable, and barely manageable to move around by one reasonably strong person, and about amp hours each. This is really amazing. Tesla solar roof is a cool thing and very forward-thinking, because it addresses the new construction market and the big-spender market, which are both very large!
However, from a Mustachian perspective, a Tesla roof is like a Tesla car: a beautiful piece of design to be admired, from a company that deserves to be supported. But if you are still at a stage of life where cost is a consideration, you need to stick to bicycles and DIY solar panels. Matt February 8, , pm. In a nutshell, prettier looking, higher cost, lower efficiency, unsure of lifespan, but probably comparable. I was researching this recently, seems like such a good idea. From what I understand — still in test and a year or two out.
They are trying to make out it will cost not much more than a regular well a tile roof. They have two types of identical looking tiles, one that produces electricity and one that doesnt thinking being that entire roof particularly the N facing will not be photo-voltaic. It also does not appear to lend itself to roofs that have hips, dormers, multi planes, etc. Who knows, when it finally comes to market cost may come down, but today its in the rich folks only bracket I believe. Ben Nelson February 7, , pm. Hi Friends, I was very excited to install my own solar this past summer!
Faceplate power is 6. I did a pretty complete write-up on it with the hopes of as many people as possible learning from it. That includes planning, installation, budget, troubleshooting, and more! Seriously, if I can do it, anyone can! TJ Schultz February 9, , am. I live just about an hour north of you and I would also prefer to buy locally produced panels when I decide to install this type of setup on my garage.
Ben Nelson March 10, , pm. Renard February 7, , pm. You bum…. I was just getting my data together to send to you! Very nice write-up! My wife and I did a DIY ground mount array of 6. We put it on the ground because our roof is 10yrs old. Using the PVWatts website our production thus far is beating expectations.
It was relatively easy to install, with the ground supports and their concrete being the worst part.
7 Ways to Power Your Home With Renewable Energy
Like when I cut the water lines with the trencher. The local power company was helpful but dubious of ability. If they go up, we make more money! In the two months since we got it up an running our electricity price has gone up. How the hell can he do that I thought. We average kW in sunny Florida in our 2 story sqft home. So digging even farther through your blog I discovered some hacks…. So I did, we did an experiment…killed the dryers one upstairs and one down …. Well we found a ton! Water heater set too hot, 2 amps. Old dishwasher 12 amps, and the list goes on. Making a few easy changes we dropped the used not counting the solar to less than kW.
Still too high, but on the right track. We keep the air at 80 in summer and 63 in winter so not that :. Since wife is into historic preservation buy older homes to fix up and remodel for extra cash every few years so we have always been limited by the home as it was originally designed. Well we are finally considering doing one for ourselves and with the kids finishing high school it can be much smaller. Reading your blog has given inspiration for many aspects of our lives, working less, living more and enjoying simple things. Thank you! Of note, we went with the SMA inverter because it has an Aux power supply that you can lose when the grid is down.
Nice for the fridge. Holly February 7, , pm. Good for you! We use between to kWh per month. We replaced the furnace with a high efficiency one. Replacing all of the insulation in the home made the biggest difference for cutting our heating costs, both natural gas and electricity to run the furnace.
So I open the windows at night to cool the house down, and then close them in the morning to keep the heat out. This works like a charm for the 80 to degree days. Having a gas cooktop probably saves us electricity. However, we also use a large toaster oven to do most of the oven-style cooking. This uses much less electricity than the oven. And we also purchased an energy-efficient condo-sized washer and dryer set, and we only run them when we have full loads.
My husband often hangs the clothes to dry. Changing light bulbs really does make a difference too. All the areas of the home where the lights are used the most have LED bulbs. John N February 8, , pm. I use 48 kWh per month. Wales, UK. TheHappyPhilosopher February 7, , pm. Very cool. Curious, what would the cost be to install a similar system if you outsourced everything to a local solar installation company?
Mrs PoP February 8, , am. Bruce A Johnson February 7, , pm. This time I know our side will win. You are absolutely correct that there is satisfaction beyond the monetary in solar energy. This time I know our side will win! Ben Nelson February 9, , am. One of the other commenters here, Bruce, was one of the many people who inspired me to do solar. The more solar including good DIY systems!
Spread the good word! Todd S. February 7, , pm. Congrats Pete and good work. Per the monitoring screenshot, it seems to be working nicely though. Are you still working with the Longmont elementary school to look into solar for them? Lemme answer all your damn questions! Shaw Solar looks like a great outfit, but Durango is far for periodic service visits.
I upsized the inverter because the extra cost was minimal and I really hope to add a LOT more panels to the system. My new strategy is avoiding bureaucracy when trying to do good around the city — either do the good without asking, or partner with people who are free from the burdens of lawyers, banks and overseers for now.
February 8, , pm. Open offer to hit me up with solar questions in the future. All in the tribe I suppose. Jamie Costello February 9, , pm. Im curious if you have a link for those classy LED replacements you speak of. Thanks for this article, it has inspired me to give solar panels on our personal home a harder look. Money Mustache February 10, , pm. Hey Jamie — sure: after shopping around the local Home Depot ended up having the best LED fluorescent bulbs, surprisingly enough. They were Philips brand in the T8 shape and the school required a K color temperature.

CRI — colour rendering index — is most important. It shows how balanced the spectrum is. Tony February 10, , pm. That was going to be my question, whether or not you could add to the setup later. So as long as the inverter can handle the input, you can add more panels? Considering solar on our garage but maybe starting with one side of the gable…. Be carefull how much good you do outside of the bureaucracy.

The world is going solar
Start a small business. Reach out to people who run companies in your area, and find ways to help them. Use Craigslist for most transactions, and meet the people in your community. These are things that help make you more pleasant to be around. Charming myself — I still have lots of work to do in this department. But at least I know the general direction I want to take my life, and how to move in that direction. Colin February 8, , pm. In the last year my two best project-doing friends — who lived within walking distance — moved away. Marcia February 8, , pm. I have friends that pop over and help!
I have helped other friends with sewing too. My neighbors have traded their skills with building and planting and growing. My other neighbor is a chiropractor with lots of friends who do landscaping, building, and are fishermen. Lots of trading going on! I bought from ML Solar, which had the best prices I could find, and luckily just happened to be 60 miles from my home, so I went and picked them up for less than the shipping would have cost. Managed to get all the panels in the back of my Jetta wagon, and the racking on the roof. Mount the solar panels just high enough to comfortably walk, drive, and park beneath then rake in the free solar.
Same goes for parks in need of a little shade. This would make loads of sense, because parking lots are usually completely unshaded. Some cities already have large installations like this in place especially places like Phoenix where cars and summer sun are a super-unpleasant combination. The key to making it all work cost effectively is a really cost-effective system to bolt together over the existing parking spaces.
If you can minimize the engineering, steel, concrete and building permit aspects, then things start looking much better. The same argument applies to choosing small, lightweight bike infrastructure over the massive stuff we need to build to support cars! Almost all the County buildings here in Santa Clara County are doing that now. Even the Elmwood Jail has solar covered parking for the employees. Kris February 9, , am.
Michigan State University did this in the past year for some of their huge lots on the edges of campus. Chuck J. February 10, , pm. Sarah February 24, , am. Next up: solar panels as the roofs embedded in hoods, trunks, windows? Maverick February 9, , am.
If you ever have the chance and are in north-central California, visit the Sierra Nevada brewery in Chico. The parking lot has about 11, panels mounted on racks about ten feet up. The racks also support hop bines growing up them, for an extra bonus. I bet it was generating nice returns on the blazing degree day I was there one summer. Anne Marie February 13, , pm. They did this at my workplace! Anonymous February 7, , pm.
