solar lantern batteries
Is it better to recharge batteries in series or in parallel?
I have 2 6-volt rechargeable lantern batteries, and 1 6-volt solar panel.
Would it be better to recharge then in series or in parallel?
I asked this 3 times in the environmental groups and never got a single answer, so maybe one of these “scientifically enlightened” evolutionist can answer. I will just have to make sure I do the opposite of what they say so that I will have it right.
You can charge batteries in either series or parallel – the issue is not just the method of connection but also the voltage you can apply.
Two 6-volt batteries connected in parallel requires 6 volts of charge because each battery “sees” the charger individually. In series, they need 12 volts to charge because the charging current passes through both batteries before completing the circuit.
So you need to recharge from your solar

The future of building technology is here and it’s full of holes. The Swiss cheese exoskeleton shell of COR, the first sustainable, mixed use condominium in Miami, Florida is a hyper-efficient smart skin simultaneously providing the building structure, thermal mass for insulation, shading for natural cooling, terrace enclosures, armatures for energy producing turbines, and loggias for congregating at the ground level.
COR, represents a dynamic synergy between architecture, structural engineering and ecology. The design is not only revolutionary in sustainable terms, but in visual impact. The impression of this building is arresting even in light of the current architectural trend towards irregular, non-linear features exploding upon the recent architectural landscape.
The building rises 400 feet, and seems to float over the city as a futuristic and ethereal being, punctuated by a multitude of round Swiss Cheese holes, which at times come

Why would a home or business owner opt for a solar exterior wall light? Such a question might be based on the earlier reputation of solar fixtures, which had notoriously limited ranges of illumination and battery life. Today, that is all changed and a solar exterior wall light will not only be powerful and long-lasting, but will also come with the same necessary features as any “hard wired” and electrically operated fixture.
What does that mean? Well, today’s solar exterior wall lights will have many options in bulb configuration. If a single source of light is required; that is available, should dual bulbs be needed; that too is an option, and should a floodlight or spotlight be required; there are also many choices for such a feature as well.
The light source on all solar exterior wall lights will be from LED bulbs, which have a brightness equal to any fluorescent bulbs,

Can LED christmas lights charge a solar cell fast enough to make it self-sustaining?
I have been looking at solar cells. I am having a hard time to find out how much power a solar cell uses from a car battery. I was just wondering if you could create a cycle where the system can just recharge it self for a long period of time.
No
