Cost of Solar Cells

Joseph
Joseph's picture

I've often thought about converting our home to solar, but until recently I've been under the impression that the cost outweighs the benefit (one a pure cost-to-cost basis). I have to admit that I have not done much solar research, but I'd love to hear from folks who have converted their homes to solar energy. I have heard that the technology of solar cells has improved at an amazing pace where the charge rate is much faster, more efficiently retained and stored, and much cheaper to purchase than previously. Thanks for any help you can offer.

Re: Cost of Solar Cells

A few are still waiting for a half price solar system. Don't wait or global warming will win first.

With incentives many systems are about half price.

As power companies continue to raise rates you save more with every increase.

Re: Cost of Solar Cells

An important item to remember is that solar cells and equipment may get cheaper but your cost to have a system will be about the same. Why ? Becuase there are incentives that are rated by year and each yet the incentive is reduced by about 10%. Even clean energy won't get a fat incentive forever.
Also the cost of labor goes up. Electric rates keep rising so it will seem cheaper to have your own safe clean power. The best time to install solar is now.

To compare look at Japan. The have no incentives and everyone intsalls solar panels. They also have some of the highest electric rates in the world at over 20 cent s a kwh.

So don't even expect a free ride. If you pay a fair value you will keep your osts from going up but not get rick off solar panels or othr renewable energy. Clean quailty cost money.

PS you can invest in comapnies that are clean and your returns could make you a few bucks. Sunpower solar has gone up almost 100% this year alone. First solar when up anout 500% .

Re: Cost of Solar Cells

Billy, A lot depends on the incentives and net-metering in your area. All solar PV and hot water dealers have those numbers in your exact area. Call them and learn the deal. Call 3 and get different views.
I save over 100 a month and my system cost was 12K with no incentives. I installed it myself and fought for net-metering and my utility is the only one to offer it to me and all solar users. When I did it in 2001 they had 8 grid tied customers, now they have over 500. Imagine what a really good net-meteing policy could do. Imagine it nationwide for wind and solar and small hydro. Go renewables.

Re: Cost of Solar Cells

knoa and Billy,

Being more efficent is the first step. A compact florescent bulb pays for itself in 1 year or less . a old fashioned incadensent bulb make 90% heat and less than 10% light and we call it a light bulb ? It heats the air and if your colling the house with Air Cond that's dump. It uses 100 watts and a CFL compact uses 1/3 the power AND makes less heat.

Other simple items, shade sceens and over hangs, solar screens to block heat but not light. Energy star appliances, a cloths lines instead of a gas or electric dryer. It all adds up a lot.

Re: Cost of Solar Cells

I have seen an installation where solar hot water makes sense with two pannels. This seems affordable, with a relatively short payback period. You need a large array of pannels, and it gets costly to do whole house heating, even with utility rebates, tax credits, etc.

Ed Begley should weigh in on this - he's got quite the system! Bill Nye (the Science Guy and Ed's neighbor) said he installed 20 pannels to get 4 killowatts. I've read the average conventional home needs 5kW. Maybe 2kW in a very energy efficient home.

There is talk of more efficient/affordable technology in the works, which would be great.

The first step is to reduce and conserve - better insulation, less air infiltration, more efficient lighting and appliances. Turn off unused lights and appliances. Less demand means a smaller energy load required.

Re: Cost of Solar Cells

check with local incentives from your free estimate solar installer. There are now federal as well as local incentives. Don't forget net-metering and renewable energy credits.

I installed my own grid tied system in 2001 aqnd it's paid for itself already and keeps getting better. I add to it and also use passive solar screens, solar hot water, energy efficient appliances. It reduces pollution, is safer than nuclear and lasts for 40 years. Solar also doesn't use any ater like coal and nuke.

It's more than the dollars you save.

Re: Cost of Solar Cells

Hi there!

I read your other post on the Hybrid forum - your a good example for us all to follow - any additional thoughts on what someone like me can do - I live in an appartment and I don't have the resouces to buy a solar system and I doubt that my landlord would do it - he's not the most enviromental guy... I REALLY want to do my part and any suggestions you have would be really helpful!

Thanks in advance!

Renting Solar Panels

Hi Joseph:

I designed and built a very energy efficient passive solar home recently and had planned to have solar electric, however once I actually looked at the high initial cost I decided to buy my electric from the local power company. I am not happy about this since they generate almost all of their electricity from coal, and I have seen firsthand what an environmental catastrophe this is. Recently I learned about a new company called Citizenre, that has a plan to make Solar electric much more widely available by renting the systems, instead of selling them. They have eliminated the upfront cost and even made it cheaper to go with solar by locking in your current electric rate for 25 years. Although it will still be awhile before they are able to install the systems, I have signed up my house and even become a salesperson for this company. You can get more information at www.jointhesolution.com/kevineigel.

Re: Renting Solar Panels

The companies like this that offer to rent solar systems sound nice but I have never seen them actually install any. Also just like renting a home or car you own nothing. Minje is already paid for itself after 7 years and will last 40 more. I'll save for a long time.

They also say they will produce their own solar panels and inverters. They are really top notch companies that have very good products at real great prices. I don't see how they will ever many better panels or inverters.

 They seem like a sham so far to me.

How much does it really cost?

Hi Kevin,

I have a 2800 sf home and I have a nice area on our roof that faces NE - how much would it cost and how much would I REALLY save if I installed the solar panels?

Thanks

Billy
