Last time I priced it out (admittedly a bunch of years ago) it rang in around the $36,000 mark to fit my housing electrical needs.
YiamCross wrote:... batteries for storage ...
If you want to be pure off-grid. And depending where you draw the line with regards how much battery storage you can be looking at anywhere from $5k to an equivalent cost to what you paid for the array. However, if you connect directly to the grid pushing any excess power to the grid and using the grids energy during off-peak (to the consumer that would mean no sunlight) hours, then you can do away with the costs and storage space for the battery array.
I can't say for other locations, but here the energy companies are required to pay "micro distributors" the same per kWhr they charge. So the primary cost to you for the energy provider is the administration fees (which means you're not independent and those fees alone can be ouch). Point being: there are choices and pros and cons to weigh - so many and all together we who are contributing to this discussion haven't covered them all yet.
YiamCross wrote:... control circuitry to make it all work ...
Conversely, what's the cost on the control circuitry for harvesting and processing fossil fuels? Speaking of solar: This I did not price out - however, I have seen setups from very simple designs which wouldn't require much to full blown computer controlled environments which I would expect to be in the $10,000 to $20,000 range.

Conversely: equivalent cost for those needed to harvest and process fossil fuel? For solar I'd expect another potential $10,000 here for someone else to do it for you.
YiamCross wrote:That stuff doesn't last forever so you have to factor in the cost of maintaining and replacing stuff.
Conversely: costs for replacing and maintaining everything from the tools and vehicles required to sink the oil rig through processing?
The nature of the structure of good solar panels is such that they commonly have a 20-25 year warranty period. That range was a few years ago, for a recent example I looked up
http://www.canadiansolar.com/ and they have a 30 year warranty to ensure the actual power output will be no less than 83% of the labeled power output of the solar panel. Gives one an idea just how soundly built a good solar panel is given this warranty period factors in damage from nature such as hail.
If you design your setup with a little thought, you may be able to produce a reasonably priced design that can protect your array from the elements while having minimal impact on the sun getting to the array. That extends the life to the array. As it produces electricity in the form of direct current - you have no moving parts. To consider how often you would have to maintain such a setup, you need only ask:
- How often do you maintain the electrical wiring in your house?
YiamCross wrote:Distributing the power is not. Same with solar.
True... but if you, the consumer, go totally off-grid you are not concerned with distributing the power to others. If you stay grid-connected so you do without the battary array, you can let the energy company deal with distributing the power.
YiamCross wrote:Do you think the land needed for a solar farm is going to be free?
Land for any purpose is not free. That has nothing to do specifically with solar. And the price of the land won't change whether you're buying it to put a ranch on it to breed horses or putting a solar array up.
The individual who is not looking to go into the energy distribution business does not require the kind of solar farm you refer to. Again, just to be clear: this point you are refering to would be of interest to someone wanting to put up a business for energy harvesting/distribution. Depending on the size of your roof and your average electrical needs - specifically in my case: I have all the space I need on my roof for the solar array.

You're crossing that of a business with that of a consumer again. Your negative points on solar are those from the perspetive of a business - review your own points. You just produced a positive point for fossil fuel from the perspective of a consumer: "buy it from [others] cheaply and easily". Your negative points against solar are all about up-front costs. Your positive points for fossil fuels completely ignore those costs in favor of someone else already having foot the bill.
I really wish I had some cold hard data from someone who has designed a simpler system to meet their needs, what their up front costs were, what they would paying the electrical company over the years, what they have been paying in the event they stayed grid connected, and so on: to be able to clearly identify the point at which the energy you collected from the sun - relative to the energy you would have paid for from the utility company - meets. In other words: at what point the solar array pays for itself.
Obviously if you compare only the up front, short term costs of putting up a solar array to "fill up the tank" on your electric car with the short term costs of going to the gas station for a fill up: the fossil fuel is infinitely cheaper. It's equally correct to say:
It's infinitely cheaper to go to the gas station to fill up the tank on your car then it is to put up an oil rig on your own farm to harvest the fossil fuels to fill up your tank.
You want compare the costs of the solar to the costs of the provider then you must do so over a long period of time. As a very rough calculation with inflated costs giving the utility company the benefit:
- $40k (rounded up) + $40k (assuming I could fit this sized battery array in my basement) + $20k + $10k = $110,000
Assume I already have a good chunk of land, could I sink a basic oil drill with $110,000? Granted, if I could and did and did have a pocket of fuel under my property, then I could become a very wealthy person indeed - or in the alternative, hoard the fuel for myself and likely have many generations worth.
On with the solar comparison calcluations to give an idea what needs to be considered:
- Current bill (both electric and gas): $210.89
Assuming that, as the avg cost each month, it would take 43.5 years to pay for the array based on the previous costs listed. I can't say what the costs are in your area, but If you price things out relative to Edmonton, Canada - you'll find the previous prices listed is very expensive relative to what would actually be paid. And - of course - depending on the setup you aim for, the prices are going to drastically change - I'd estimate your low figure is likely between 35k to 40k.

I disagree. From the business people I know including a couple start ups along with the discussions I've been involved in with the bank, the viability of a business is determined by the anticipated 5-10 year profits the business is expecting. Perhaps the business people in your area look at things differently then here.

I'll agree with the wording:
- If the profits from a solar panel farm could compete with oil and gas then you can bet your ass those with the capital to invest would be building solar farms as fast as they possibly could.
YiamCross wrote:When you work out the cost of a unit of energy gas and oil beat solar hands down right now.
I did work out some of those costs from the perspective of a consumer - again, a good number of years ago. The straight costs for the solar panels alone - assuming the cost per kWhr from the electrical company did not change - would have the solar panels paid for in 23 years. Do you really believe your utility company is going to freeze their prices and not increase them over the next 2 decades?
YiamCross wrote:... it will never be the best option in every situation...
Didn't say it was. We're lucky here in Edmonont. Throughout the year we get an average of 6 hours of sunlight per day - this takes into consideration factors such as cloud coverage which would drastically drop the performance of your solar array.

I'll take your word for it, I have no idea what an "over unity" system is.
