for solar energy storage you're best of with deep cycle AGM absorbed glass matt batteries...
much safer and long lasting than normal lead acid!..
yes good airflow is always needed to keep temps stable as are some proper threaded terminals :wink: !!..
i'm currently converting (well it was designed in the build, as it's new) My Design studio to run off grid electric...I only have 600w of panels but with L.E.D lighting and underfloor heating it will basically run self sufficient..should be enough to charge my bike for free too. (well maybe need another panel or two..)
Powering your home/workplace from a centralized grid system and traveling to a pooled source of (expensive & polluting ) liquid hydrocarbon fuel is just so 20th century...
we live in the information age!...technology (with the correct information and ability to understand it) has empowered the average man to become his own power and refueling station...freeing him from the control of others who provided him fuel for travel and warmth in the past centuries...(at the premium of their choosing)
I mean...my smatphone has more power in it than the pIII PC i built to use at university 10 years ago (thousands of times the power of the moon landing computers)....and the half a million pound sinter station/rapid prototyping 3d printer i used at my university that cost half a MILLION £'S well i'm in the process of building a very similar spec machine for my solar studio for a couple of grand!!..
In fact we have had equal scientific development and technological advancement in those ten years than we had from 1900-2000...that is the pace today...it will only take till 2015 to do it again..then 2017 then... 2018 then we will go into doing it every couple of months..a month..two weeks...a week...all before 2020... its called the law of accelerating returns..we know it also as moors law but it applies to all technology not just computers and transistor size...
oh just to talk about the two best advances in solar tech recently both by 12 & 13 year olds!!... (we should be ashamed!!
Aidan Dwyer, a 13 yr old that has used the Fibonacci sequence/golden ratio 1:0.618 to build a solar tree!..he arranged mini panels on branches at different angles determined by the golden ratio...this is how nature/trees spread their branches and point their leaves for maximum solar absorption....his solar tree arrangement was up to 50% more efficient than the panel area of the tree just laid out flat. (well at least in the morning and twilight hours) as different leaves absorbed more light at different times of the day!....his was only a small model..but i plan to build a full scale tree in my garden maybe one day...
the other is 12yr old William Yuan ► 3:06► 3:06

with his new nanotech 3d solarcells that he is now working with industry to produce that will be 900% more efficient...
and there's always solar paint!... http://www.engadget.com/.../notre-dame-heralds-paint-on-solar-c...
we should never need to see a power bill again!...
