Solar Power Cost Analysis
What Affects Solar Panel Costs
Alternative Energy Questions:
I seek to build deep-cycle batteries.?
I did a benefit/cost analysis of solar power and it is too expensive due to the lifespan of the storage batteries . I know about chargers that can extend the life of batteries but that is not enough. I seek good simple designs so I can make them myself. I have 370 lbs of lead and an electric furnace to melt in. I expect to be able to take the plates out individually if they need repaired. I further accept that the batteries will be much larger than a purchased battery at the same output capacity. I am willing to sacrifice structural toughness as the battery will not have to endure any kind of mechanical shocks or vibration.
Some primary concerns: Making lead oxide, reusing lead oxide from other batteries, pressing the oxide into plates, avoiding contamination of self and home, and how much antimony to use.
Thanks
I'd reccomend against this, there are a myriad of dangers dealing with molten metal and especially lead. I've known people that work in battery factories (interstate) and they tell some ugly stories, it takes very little lead (and even less lead fumes) to do alot of damage.
As far as creating your own alloys this is fairly foolish as well. The main killer for batteries is corrosion and failure of the lead plates. However careful you think you are you will never get the same quality and workmanship as a large manufacturer using modern tools and methods.
Look into industrial deep cycle batteries, they have lives projected at 10-20 years with good practices, your PV panels are probably only going to work for 25 years so its a decent match. You can buy some serious batteries for a couple thousand, imagine your solar sells are going to set you back more than that
If you are crazy enough to want to make your own then melt it in a very open area, wearing a respirator with the wind going at your back. You want the plates as thick and uniform as possible. You will never get a good pour by hand but if that is what you want, that's the only way to do it.
As far as re-using lead oxide I'm not sure you need to. Lead is pretty cheap, just buy some new lead. The old lead can be re-melted, its not going to all be PbO, just melt it and take the slag (oxide) floating on the top.
I hope you don't create a big environmental issue on yourself or your property, I'm sure you will spill and contaminate everything with the fumes.

Global carbon emissions have become a central focus of developed nations in attaining the twin goals of energy security and sustainability. In order to achieve this twin target of security and sustainability, there is an acute need to produce energy from the sustainable sources such as wind, solar, geothermal and biomass. The global financial crisis has provided opportunities to governments to move forward in altering the present energy generation mix. The financial stimulus packages announced by the major developed nations have allotted almost $512 billion to green energy. On the basis of announced
stimulus packages to 31st March 2009, the observation can be drawn that the Asian nations, especially China, have contributed the most to the green energy projects. South Korea has allotted the maximum amount to the green energy, followed by China.
Global Solar Thermal market was concentrated in the US only till Spain joined in 2007. Since 2007, the sector has broadened its geographical reach and Australia and Morocco has also started the solar thermal plants. Due to the high energy efficiency, the technology is gathering the interest of the other nations with the planned projects coming online from 2010. Global solar thermal cumulative installed capacity has grown from 354 MW (Megawatts) in 2001 to 697 MW in 2009 at a CAGR of 9% per annum. However, the planned projects that are coming online from 2010 onwards are anticipated to accelerate the CAGR to 46% per annum during 2010 to 2020. In 2020, the solar thermal power capacity is expected to reach at 122,252 MW from 2,715 MW in 2010. The annual installations capacity is expected to witness a big surge in the coming decade, primarily due to the significant capacity additions in the US and Spain. Additionally, the capacity addition will be supported, as many other countries like Australia, China, the United Arab Emirates (UAE), Algeria and Italy are coming up with the CSP (Concentrated Solar Power) projects.
The US solar thermal market grew at a CAGR of 2% per annum from 2001 to 2009. However, the government encouragement for the sector is expected to lift CAGR to astonishing levels of 46% per annum for the period 2010 to 2020. The installations are expected to pick up pace as high capacity plants come online during the period. California is expected to lead the CSP installations with almost nine projects with a capacity of more than 500 MW expected to come online during the period of which one project is having capacity of 1,000 MW. The sector growth will continue to be robust till 2020 as the RPS (Renewable Portfolio Standards) targets for the states will continue encouraging solar thermal power generation in the country.
