A typical Australian house consumes around 18 kilowatt hours (kWh) per day so a 1-2kW system displaces an average of 25-40% of your average electricity bill. There was an article about a solar system being installed in South Oz at a water treatment plant where the panels are floating on the ponds. As to my panels they are 280 W monocrystaline with an MPPT voltage of 35V at 8 A under standard conditions. The system is augmented from a 2800 W grid connect inverter and panels on my sons house that back feeds any of his excess PV power into my by-directional inverters and dumps this excess power back into my battery bank to replace what he get from me at night.
The system has been recently upgraded with 2 off peak ( controlled load 1 ) 1kw (50V 20A ) Battery chargers that are controlled from a micro processor algorithm sensing battery charge condition and only charge when absolutely necessary. I have measured 30Kwh out of a 5 Kw solar PV array in late November 2014 during a heatwave. I used 26 kwh that day mostly on air conditioning and increased demand by the Fridge- freezer.

You will need to know two things – how much electricity you use and how much sunshine is available where you live.
If you already have electricity from an electrical utility, this will be an easy question to answer.
If you don’t have electricity yet and are planning to use a solar power system instead of connecting to an electrical utility, you will need to estimate what you are going to use by doing a load analysis. Now that you know what you need for electricity, it’s time to see how much power a solar panel can produce and how many of them you will need. If you have full sun shining on the array for one hour (1 Sun Hour), the array will have produced one kiloWatt-hour (kWh) of electrical energy. The average number of sun hours per day for your area can be found on a global solar insolation map or you can focus more closely on a map of your own area. Once you have chosen a system size that works for you, the next step is to choose a suitable mounting system.
I can very easily answer the question “How much do solar panels cost?” (see below), but I think the real question you’re asking is “How much will it cost to put solar panels on my roof?” That’s a more complicated question to answer, but I’ll explain in more detail and provide some useful perspective on that in the article below. When you ask, “How much do solar panels cost?,” what I think you really want to know is how much it costs to put solar panels on your roof, right?
The bulk of the price of going solar is now the “soft costs” (installation, permitting, etc.) rather than the solar panel cost. The total price of a system, of course, varies tremendously based on the size of your roof and your electricity needs as well. So, the key is really just to get an initial quote and then get a closer look at your situation from a local installer, who can give you a more specific quote. But when it comes down to it, what you probably really need to know is how much it will cost you to actually go solar.
In many places, you can now go solar for $0 or close to $0 down through solar leasing companies or through simple bank loans, the latter of which would generally be my preference. Studies have found that the average solar homeowner will save about $20,000 over 20 years from going solar. Furthermore, solar panels are likely to pump out electricity to a similar degree as when new for well over 30 years, perhaps even well over 40 years. But, again, the financing options and the savings really depend on where you live and some personal circumstances (like how much you’re spending on electricity right now).
For a little more of a look at how prices and savings can vary by state, below is an infographic based on 2011 research. I hope that infographic and article helps you in considering the many factors at play that influence the cost of solar power.

Zachary Shahan is tryin' to help society help itself (and other species) one letter at a time. It is interesting to see that the maps hardly reflect the differences in available solar irradiation. Indeed it is worth switching to solar panels for saving money in the future .Although it will cost you a lot when you buy,the fact that a electric consumption is much lesser cost that you can benefit for about 20 -25 years. Yes, its true that last few years have seen a considerable amount of reduction in the prices of the solar panels which has made the solar roof top technology a feasible option for the people in America. With a ten year payoff and a 30, 40 or more lifespan solar will save buyers a heck of a lot of money. Hypocritical trolling from someone who frequents Brietbart, Glen Beck and other ultra-right wing political sites.
Someone with the initial capital is invite me to produce solar panel, what are you recommendations?
Are you talking about buying just solar panels or you talking about an installed solar system? So I would consider possibility of trying to maximize the size of the system; or at least not be limited by usage as the ceiling.
Best if we each generate just enough to meet our needs when balanced out with a battery system to draw down in inclement weather.
Cyclocross started in Europe more than one hundred years ago when cyclist were looking for a way to stay fit in winter.
Cyclocross requires the power of a sprinter, the speed and endurance of a time trialist, the bike-handling skills of a mountain biker and the tactics of a road racer. It is not surprising that cyclocross has become the fastest growing part of the sport of cycling in the U.S.


Events foster a festive atmosphere and encourage everyone to have fun while racing as hard as possible.
To further explain why Krugman is simply ignoring reality, check out this excellent post from Todd Myers of the Washington Policy Center (our sister think tank in Washington State).
Meanwhile, even the International Energy Agency, no friend of renewables, is forced to admit that renewable energy prices are becoming cost-competitive with fossil fuels.
Unfortunately, the United States is far behind countries like China, Brazil and Germany when it comes to renewable energy.
The International Energy Agency has included hydroelectric power in its renewable energy market basket in order to make the cost per kwh of renewable energy competitive with coal and nuclear. The numbers in the bar chart above may be a factor of two high for PV and quite low for the fossil fuels, but Krugman is just wrong on this.
It is completely ironic that a technology comes along that liberates the individual from dependency on centralized electricity generation, yet must face the wrath of the libertarian movement. It does make sense if you understand that unfettered capitalism will degrade itself into defending its previous capital expenditures at the cost of its own future viability. In a world that is not spending all of its creative talent defending obsolete capital expenditures, individuals using the sun for their needs would make total sense to the real libertarian. I am all for people using whatever solar power (or wind, or whatever) they want for their own personal power generation. The would-be free market is already distorted by government subsidies, import dumping, investor owned monopolies, and the right to pollute at no cost to the polluter.
When government creates and sanctions a monopoly and sticks it right in the middle of commerce, this is a subsidy, a market distorting subsidy. It will be difficult for free-marketers to avoid calling externality measurement and allocation a form of regulation to be eliminated. Subtract from that the poor efficency (higer effenciencies are obtained by using larger collectors and focusing to a smaller area like a mignifing glass but remember the 2 kw per meter limit), cloudy days, night, and the inefficiencies of storage systems (for cloudy days and night) and high maintenance (like a dirty window a dirty solar panel face is less light to be converted) and solar equates to poor power conversion.
Depends on how much power you consume as well, some people sell power back on to the grid too. Yes, don’t confuse me with charts or graphs showing how much of the burden for YOUR solar is being paid by WE the taxpayer!
The Rio Grande Foundation is a 501c3 non-profit organization and your donation is tax deductible. The most common household systems are either 1 kilowatt (kW) or 1.5 kilowatts, although some property owners have installed systems of up to 10 kilowatts.
This was claimed to give a 53% increase in output as the panels are water cooled increasing their efficiency as well as reducing the evaporation of the water and algy (sp) growth as well .

Solar is a great idea for many people, not only to cut their utility bills but also to reduce their dependence on their utility, while also cutting their own personal footprint.
There’s tremendous variation in the cost of solar panels based on the type and efficiency of the solar panels.
In three of the four most populous states in the country, that 20-year total is actually $30,000. In Hawaii, it’s up above $60,000! After years of covering solar and EVs, he simply had a lot of faith in these companies and felt like they were good companies to invest in. Moreover, incentives and the rebates offered by the federal and the state government have made the solar technology actually a lucrative option for the residents. If you took oil in the first years of development or any other new technology it would also show unfavorably. The power exported paid for all the power we bought, plus more than half the fixed $1 per day ripoff fee to utility Co hits us with. Things have changed since then, but the article is popping up on my news feed as if it were current.
This explains our local electric monopoly fighting to keep its old polluting coal fired power plants running despite the damage this policy does to utility’s own future. And, unless you are completely off the grid, you benefit from the grid which is paid for by the rest of us utility rate payers.
Solar energy is very beneficial, and if this person would rather pollute the earth with fossil fuels, they don’t deserve to live here. We do not accept any government funding; our funding comes from private donations from individuals, corporations and foundations and every dollar counts. The table below shows the average daily production of some common grid-connected systems throughout Australia. I believe that the output of a panel decreases by 0.3% per degree C temperature rise, So if anyone came up with a PV panel with a water jacket and heat pump to create a hot water service and keep the panels cold there would be savings for power and hot water. Of course, it does depend on the particular panel and where it is located geographically and on the roof. However, the type of panels used for residential solar installations is quite standard and the costs are basically set globally. For residential solar modules, which are typically of a higher efficiency than solar modules used in utility-scale solar farms, the figure would be a bit higher.
The story hasn’t changed much since then, even though prices on both ends have come down.
However, in this case, your payments are likely to be less than the amount of money you’re saving on your electricity bill.
Well, through my research I have found that the average cost of the off grid residential solar system in USA is around $3.75 per watt and it is without any rebate and tax credit offered by the government. At the same time, as an environmentalist, I would not mind producing more energy than I consume; the excess in grid-connected system will still be used by someone.


How a company treats its shareholders versus its customers shouldn’t need regulation (but it apparently does). I have LG Electronics LG275S1C-B3 solar modules (panels) and each is rated at a Maximum power in a standard test condition (Pmax) at 275 W. Either you go for whole energy consumption of your bill expense or just target specific appliances as a startup. That cost has fallen tremendously within the past few years — they’re now about half the price they were in 2008, and more than 100 times lower than they were back in 1977. So, really, you’re not paying any more than you’re already paying for electricity … you’re saving money! Zach is recognized globally as a solar energy, electric car, energy storage, and wind energy expert. You made a right point that state like Arizona has lower payback period than the other states in America because of its excellent policy for the solar roof top.
Just because I don’t get paid for excess does not mean it would not be good in grand scheme of things. Investor owned monopolies actually assist high-cost renewables because they don’t have to compete on price. I’m not saying that this is a total non-issue, but existing non-renewable fuel sources are already regulated heavily in terms of pollution. Pollution requires regulation because it brings harm to all, not just to the parties to the transaction.
Compared to what I wrote before on this subtopic, What size solar system do i need?, I list factors that we need to consider when defining the solar panel capacity that is run. Telsa Power Wall + numerous other brands – there is HUGE competition here already in this area, and prices will be heading down very soon). The devil is in the details, but for a lot of us it makes perfect economic sense even if you don’t care about cutting FF emissions. We just need to notice that is not okay to sacrifice everyone’s health for cheap electricity. But for now, we are going down a little bit deeper, which includes some easy calculation (link) that not only defines how many, but also how big solar panels need to be.
That means you certainly can define what size solar panel you need.Before we start the calculation, how about we recap back to the relation between the three factors that I mentioned in my earlier post here? By doing this, we are also determining whether we target specific appliances to cover the energy expense. With the total amount and duration of sunlight, we know how much energy we need to fulfill our appliance needs, just as I referred to in the first factor. And lastly is the rating of solar panel we use; for me, this factor is more to determine how much electricity we can produce per day. It takes measurements from the total amount and duration of sunlight multiplied by the wattage rating of the solar panel.
For example, if we take a solar panel rated at 500 watts and we get about 5 hours of direct sunlight per day, the total watt-hours provided would be 500 into 5, i.e. By getting this info, we can simply determine if it is enough to fulfill our average kilowatts needed.
For example, we cannot produce 2.5kWh electricity if we only have 3 hours of rising sunlight. To start, you can either look at your bill or refer to the Energy Information Administration (EIA) to get average reports on energy expenses per household. And for the amount and duration of sunlight, you can refer on my first post.Image above credited to solar quotes. Referring to the image above, if you really want to get more details on how much sunlight you may get, you have consider this timing, even though I don’t really recommend it because it just wasting my time. This article is created to provide useful information to individuals who want to make use of alternative energy in their residence and save money. Bear in mind, the below calculation are just to make you understand the correlation and concept you need to follow when deciding your solar panel’s size. That means that you must change all the details according to your actual value of your energy and money spent on appliances.Do The Math To Start Saving MoneyTo begin the discussion of answering the question stated above, the first thing you must know is the exact quantity of solar panels you will need to install in your backyard to provide enough energy for your home.
And in order for you to know how many solar panels you will need, you must follow these simple steps: 1.
Calculate your average monthly consumption of electricity (kWh) The first thing you have to do is know the devices and appliances that you have in your home.
Let’s say you only have the basic appliances, such as the television, refrigerator, radio, and a couple of lights.
Then, the next thing you have to do is know the total kilowatt-hours (kWh) used by each of the appliances per month.
The average monthly KWh for the light is 50 x 9 hours* = 450 kWh; 450 x 30 days = 13,500 kWh.
Therefore, the average total kWh load per month on your home is 2,400 + 56,160 + 875 + 13,500 = 72,935 kWh. Determine the size of the solar panel you are going to install – The next thing you have to do is know the size of the panel you’re going to put up so that you will know how many you will need for your residence. What you need to do is know the average monthly load of kWh, then divide it by the average number of hours of sunlight in your area.
Let’s say the average dimension of a solar panel is 59? x 26? x 2,? and it produces about 125 watts of electricity.
Conclusion: Knowing how many solar panels you need to supply your house with enough electricity is the best start in saving some money.
