Re: How good are modern PV panels in cloudy/shady conditions

So my Q is this, has anyone got any real life experience of how panels will produce under cloud or shade, eg as a % of normal max output. They have said they can split the array so the half of the roof which gets more shade won't cut down the output from the better side, as I understand output is l...

"UltraBattery" Lead-Acid Supercap Hybrid Battery Class

Lead Acid batteries have been around for quite some time, are very cheap and easy to maintain - however, they still have many drawbacks compared to other, more expensive and complex battery technologies. However last year, taking the information known about the newer makes of Super Capacitors and co...

Re: BVS Events on the Speak EV Forum

Hoping this isn't off-topic Kevin (forgive me as a newbie :D ) but is there any events near to South Wales that you know of, as I would like to get together with other BVS members locally (even if I have to travel to Bristol to meet them) :)

Flow Batteries: The future of high-capacity energy storage?

Found this today about a new type of chemical battery being developed called a Flow Battery that has mainly been used in large-scale renewable grid energy storage. It mentions that until recently these were only available as more expensive models due to the cost of vanadium. However they are startin...
