Was considering buying a solar panel to put on the roof of the house. To reduce energy bill a bit.

But after a quick check I see that: 100W panel costs hundred dollars, And I will need to buy a battery and an DC to AC convertor. plus various other stuff to install it. And assume cost will be at 300$. How long would it last me? 5 years? Since there I see no easy way to integrate it into your power lines it will not be used 100% percent.

It seems it is not even worth it.

Do any of you have one at home? What are your opinions and costs considerations after long time of use?

It depends on your setup. For example most people don't even have batteries, they just use solar when they can and grid power when they can't. Net metering being a bonus if available.

Me personally I have a lithium battery setup, because my goal isn't saving money, but bankrupting my local utility.

Generally getting cut glass is a local business and I'm positive you have them in your area. As for them all having UV blocking, no they don't. They would advertise that and you would have to pay extra.

Costs of batteries+inverter is less significant if you buy lots of panels. A household consumes ~3kWh a day. Important stuff have to rely on the grid, like Refrigerator (probably washing machine too). So with 500W panels active ~8 hours I believe you can get 1/3 of electricity bill removed.

When you're retarded, things can seem strange and scary. But, in reality things are not so bad.

500$ 400w setup that includes 2 panels, a battery, a charge controller and a standard automotive inverter will run all of your led lights. You will need to do some electrical work as well, DIYing it would be about 200$. Note, this isn't required if you use this power elsewhere, like charging or a shed or whatever. This is my projects cost.

Here's the main point: 400w for 12 hrs a day for 360 days at average US power costs is almost exactly 200$. 2.5 year ROI results in 2.5years of free electricity if your 5yr estimate is true. Luckily it's not, and you should get 7 years of profit.

If you're looking to save money, hold off on the panels and look into offpeak metering. Use appliances that are heavy drains during those hours. If you work a 9-17, chances are you already do anyways.
Solar is viable, just not in all cases people want it for. (I'm looking at you, silly Michigan homeowners). Best application is when energy is going to be used rather than stored. Run your dishwasher, clothes washer, dryer(if system supports it) and so on when you have sun rather than relying on batteries.

Decidedly not true. While I'll admit that this only applies to some DIY panels I was considering making, PV panels would pay themselves off in a little under 2 years going that route. Turnkey setup probably would be anywhere from 10-20, I'd expect.

That being said, I live in southern California, where there's plenty of sun and I pay substantially more than the national average for electric ($0.19/kWh).

You want super clear glass also called low iron glass. You also want it toughened.

Normal glass usually doesn't have a coating, it is an expensive option that most people wont cough up for. But if the glass is coated you will be able to feel it. The coated side will have a different texture to the uncoated side. Kind of like a dirty shower screen.

Best bet is go down your local glass shop and ask if they have any seconds. A tiny scratch will prevent them putting the glass in a window but will be fine for solar panels. You should get it pretty cheap.

>It seems it is not even worth it.

Depends where you live. You need good sun and expensive electricity.

Dont get a battery that will almost never pay for itself. Tie into the grid, you can maybe sell the surplus. Panels should last at least 20 years, most have guarantees for that long and will still work after that period.

Ofcourse you need to cool those panels. The panels are rated @ 25 C. If you go above 35C it loses efficiency. Most cheap chinese solar panels require it. Heat expansions and contraction could kill connections and therefore reduce the life of solar panel dramatically.

Without proper cooling system, efficiency can drop within an hour of usage and can continue to drop dramatically in peak sun hour.

Water spray cooling is probably the most affordable/effective method for most people. Then there's the water cooling from underneath the panel with direct contact.

A proper wind convection system would require a ton of air flow, something that would be useless given the panels themselves might not generate enough power to warrant it.

Anyone here bitching about cash return on investment is an idiot. The reason people don't want to save the planet is because it costs money. Would it be cheaper and more convenient to tie to the grid? Probably. Will you ever get a return on investment in solar? Maybe. There's more to solar than just keeping a few dollars in your wallet. The whole point of solar is that it's not pumping chemicals into the air when you use electricity. People need to change their mindset about "muh return on investment." Solar isn't about saving money, it's about investing in the future of the planet. When you donate to the Red Cross do you get anything in return? No, but you're helping others. At least by investing in solar you get to still run your electric stuff. You can't change the world, but you can do your part. Houses in Hawaii run about 50/50 solar/grid. California will require all houses made in 2020 onward to have solar panels. Maybe we'll never get off the grid, who knows. But we need to try. Do what you can solar-wise, even if it's a small amount. 20% of something is better than 100% of nothing. I personally have a solar light in my shed, and I am buying a 100W panel to run some power tools and charge my boat battery. I can't afford a lot, but at least I'm doing something and you should too.

You can get second hand solar for under 6 euro cents per watt all day long. There is a huge surplus from decommissioned solar farms. As roofing material it is cheaper than galvanized steel sheets. Expect 85 to 95 % power. Remember you can use dc directly for many applications. Hybrid inverters are good for covering power outage and reducing bills.

I mean... that's not very worth it, definitely.
You gotta install about ~3-5 KW in most cases to get your money's worth. Parts like the inverter, wiring, racking, etc. are cheaper / make more sense at scale.
If you do choose to install solar, it's probably not going to be just 'magic' that reduces your electricity bill.

Also, you can't use grid-tied when the grid is down, so if your power goes out, so does your solar. To me, solar is about being self-sufficient for energy, and making less of an impact on the environment, while it makes less of an impact on me. (Power outages due to <things beyond my control> become a thing of the past with a proper system with adequate battery storage.)

Do I expect to get my money's worth based on money saved per KWhr? Oh hell no. Averaged overtime, I assume it'd be the same as me paying utility bills for 25 years, maybe even a little more if I include maintenance and especially if I include my time as being worth something. Only difference is, I get to control it since I fronted all the money for the equipment. That to me, is worth it.

>How long will it last.

Well, most panels are under warranty for ~25 years... so I'd say that's a pretty good assumption. You may or may not have (probably will) some maintenance on the system required during that lifetime though. So earmark some money for that in the future if you do install solar.

it can pay for itself, but it will take atleast a decade or more.

solor panels work because when a photon hits an electron the electron jumps higher to another shell and realases photon and goes back down to its previous shell. if the electron is a "free electron" in the outer most shell it leaves that atom and gets drawn towards the positive but usually replaces a spot in another atom closer to the positive, its a reaction.

in a perfect world solor panels wouldn't degrade and all the electrons wouldn't leave the loop, but about 1% of a panels electrons leave the loop and cause degradation. sure a 30 year old panel will still produce power, but not at the rate it was when it was new.

also if you want 100 watts of power 24/7, your going to have to account for cloudy days so your going to need atleast 7.2 kilowatt hours worth of batteries or more depending on your location and its weather. on average your only going to get 5-6 hours of peak, so your going to need 5-6 100 watt panels or more just to keep the battery bank charged. plus a few more 100 watt panels to account for degradation so your system will still work in 15 years. plus nothing is 100% efficient and your going to have loss though heat.

nuclear is the only viable option to power the future. The risk is well worth it. Solar panels are trash in terms of efficiency and their production methods are not green whatsoever. If we can get organic based solar panels that do not degrade in a year with efficiencies comparable to what we currently have, then solar might be feasible for fullfilling minor power requirements.

The major difference between renewables (wind and solar) and either nuclear or petroleum is that renewables are supply based while nuclear/petrol is demand based. If you get a cloudy day, well tough shit if you are on solar. Wind slows down? Too bad.
With nuc/pet, you can adjust your consumption as need so that in the evenings/nights when demand skyrockets, you can increase power generation so there are not rolling blackouts.

tl;dr wind and solar are retarded no matter how much you hippy liberal faggots parade it around like it's fucking mana from heaven. It has its specific uses, such as powering remote areas and low power off grid sustainability. Trying to power civilization on it is absolutely fucking retarded.

You are very broadly applying the word public. Basically long ago different utilities were setting up their own powerlines. It quickly became a mess with different customers on the same street using different powerlines.

Good fuckoff. If oil hits $100 a barrel my dad is give me all kinds of free shit. If his company wells out he probably will get several million.

I have panels on my roof.
They're going to take 12 years to pay off, but only because I sell all power generated to the grid.

If I just used them for my own needs I would never break even.

Hey OP. Solar panels don't work for everyone, but if your location is right, and you have the capital, it may be worth it. There are many incentives worldwide for this sort of thing. If you're in the US, you get 30% off as a tax credit automatically, you just have to claim it when you file taxes. Depending on the state you can claim more incentives. Honestly the best thing to do is go to a third party company (solar service provider) that enters a power purchase agreement with you. Depending on your location, you automatically see lower electricity bills without any up front cost.
Most people I talk to seem to never realize how many options there are or how cost effective solar panels can be, so I implore you to educate yourself on it for your location. Policy incentives are the deciding factor in most cases, so learn more. All that being said, if it doesn't look cost effective for you (after looking into it, trust me you'll probably be surprised) don't do it.

If you don't have a lot of capital and are just looking for one or two individual panels, they may be better for a work shed or a project, rather than your home.

electricty in california is current 25 cents a kwh. if you sign up for peak pricing it goes down to an amazing 20-23 cents and then spikes up to 80+ during the 'peak' time making any savings you think you are getting a complete joke.

>nuclear is the only viable option to power the future.
... That's not how you spell dyson swarm and energy beaming.

>then solar might be feasible for fullfilling minor power requirements.
We have viable auxillary solar, it's called parabolic troughs and salt solutions.

>Trying to power civilization on it is absolutely fucking retarded.
You can use them to power fuel synthesis. Peak oil is technically a legitimate concept, but ecoterrorists/leftists are retarded. Eventually all energy will come from renewable, but it will be converted into chemical energy for efficiency, longevity, storage, transportation, an actually viable end product, etc
tl;dr put in your will to invest a few million into gas turbine companies.

Modern reactors made and ran by competent workers here in the US are perfectly safe, and both have higher energy production and less pollution than any other method currently in use. The problem is luddites like you who protest and NIMBY construction and upgrades to nuclear facilities, and for some reason have a right to sue.

They're just like the eco-terrorists in california that forced us to live off of 1970's population projections for water instead of building a resivour. All because an activist judge ruled that seasonal waterways that dried up completely in summers/droughts would dry up.
The things naturally dry up for years/decades at a time, and the faggots act like it was a big deal to make it permanent.

i have fixed panels on the roof of a residence. gov't buys all the energy i generate and system will pay for itself in 9 years or so. probably more than double that if i was on net metering. maybe a bit better than that. energy is only going to get more expensive.

More fun facts:
We are already have lots of experience with directional beaming.
Solar panels work in space.
Efficiency doesn't matter when the end result is more energy being received from beaming than earth receives naturally.
We already have microwave and radiowave energy receivers.
