@moviedude22 — The problem is profit and conflicting interests in what is profitable. If everyone was using solar power from the sun, nobody would pay energy companies, who make billions, if not trillions of dollars per year.
Every hour enough energy reaches the earth for to meet the need for one year?
Yet in a video titled “How Photovoltaic Solar Cells Work”, they state every minute enough energy reaches earth to meet the need for one year. So which is it, you can’t both be right. Maybe neither of you are right? I don’t know who to believe these days….maybe I’ll just make up my own reality…
My question is - what if a hail storm were to damage the panels? Who would replace them, and at who’s expense?
In the past 20 years, the demand for solar energy for domestic energy purposes has grown by up to 25% per year. With energy costs constantly increasing, governments are looking to solar energy as a more viable option to meet a growing need for energy. Pacific Crest Transformers has more information on this. You can also read whitepapers and articles on alternate energy at the Pacific Crest Transformers website
Really good video
Great video…I converted my home to a net-zero solar powered home that uses no oil or gas…I made a video about it called, “Preparing for Peak Oil”….
I invented a breakthrough source of energy that contradicts the law of conservation of energy. I have a PROOF that there are electrodynamic phenomena that contradict the law of conservation of energy. I am looking for $6M for a prototype and patents.

If you have the chance have a look at the book “The Solar Fraud” Why Solar Energy Won’t Run The World by Howard C Hayden. It is an interesting read but a bit difficult to find. Any public library should be able to get it though.
You a few good points but the subject is rather vast to be discussed just with a few lines but keep this in mind. Solar and wind energy are unreliable therefore they need the grid and conventional or nuclear power anyway to back them up. These renewables DO NOT add power to the system, they only save a bit of fuel.
For example 40-60bln$ on PV lasting 30 years (and they don’t) only allow to save 30×0.01×7bln=2bln$ in nuke fuel + installing the nuke power station anyway. 40-2=38=bad deal
You’re exactly right, but tax incentives are a way of life. Why should my federal tax dollars pay for a TSA employee at an airport in Idaho when I live in Alabama? The previous solar slump is a thing of the past. As we continue our dependence on foreign energy, rather than capitalize on a huge opportunity to become the leading exporting nation of solar and other forms of alternative energy, we’ll continue to slip further into debt and become vulnerable to attacks, in more ways than one.

bankrupt photovoltaic
ther are a few companies on the search result
If it makes sense you are welcome to install them but remember: subsidies distort the real market and pass the costs on someone else and I can provide you with real data where PV became obsolete after 9 years. Warranties are only worth the duration of the company that can honour them.
@robz40 PV allows you to generate clean electricty which you sell back to the power company for “store credit.” With the 30% uncapped federal tax credit, state rebates, and low financing options, payback can be as low as 7 years. What’s the payback on your car? PV is one thing you can actually buy that adds value, pays back, and helps the environment. Most PV manfacturers offer a 25 year warranty, when in fact solar will produce electricity for you for 35-40 years. It just makes sense.
@mikecccc987 It might be surprising but PV is uneconomical even if the PV modules on the roof are free. Why? Because they constitute about 1/2 of the total cost of a PV system.
Fortunately, isolated solar panels are very cheap and continuing to drop in price.
Your estimates on efficiencies and losses are not real, I wonder where you got them from. PV is the most expensive way to produce electricity and it needs to be supported by conventional or nuclear power anyway. But if you’re happy to spend your 1000s on your roof… be my guest.
@robz40 So, in short having the Generator ( Solar PV ) in close proximity to the load ( Washing Machine, Air Con, etc..) will reduce energy loss in transmission. PV is not cheap but it is one of the few things you can install on your home which has the potential to pay for itself.
@robz40
Also there are huge efficiency losses in the grid 50% is lost just in transmission and if you count the energy used to construct and operate the power plant producing the energy whether it be Nuclear or Coal its more like %80 - %90 ! is lost.
@robz40
Simple - to use the space on your roof to collect energy. The source of the energy coming from the grid has many hidden costs and in the U.S is heavily subsidized. I believe we are going to have to pay for these hidden costs in the future whether it’s health care for kids with asthma ( this is a huge problem now in the city I live in ) as a result of pollution , rising sea levels causing people to move or extreme weather patterns to name a few.
The WM was an example.

I personally fail to see why many people should use PV to supplement their electricity. Why spend thousands on PV when they are connected to the grid anyway?
10sq metres mentioned x1000Kwh/year x10%PV efficiency=1000kwh/year or 3kwh per day
it is not enough I am afraid.
a washing machine rated 2KW would use in 1 hour by definition 2kWx1hour
= 2kWh
They will never convince me to install those PV at the cost of £6000-8000
Waste of time and money guys
bla bla bla cheap the pannel we all love but cost???
we love the sun !!!
