Solar Panel 12V regulator

Currently i am working on a 12V solar panel. the solar panel will be charging up the battery of 12V7AH. The problem is that by using the solar panel,the voltage often to be fluactuating down until 10V. How can i make the voltage remain constant at 12V?

solar question

Do solar panels have to be in direct sunlight? I'm looking to make a "Sun Jar" and was wondering if it would work on my balcony. The only thing is our balcony doesn't get direct sunlight to it as it's inset into the building and covered by the above apartment's balcony.

Any new solar projects lately?

Is anybody planning any cool solar experiments/projects around the house this year? I want to make a solar water heater; picked up two nice large double-paned sliding glass doors at spring clean-up this year. That's all I have for now; I still need pipes, valves, and extras. I'm definately taking pictures for an Instructable.

Can anyone help with a solar circuit?

Hello! I'm trying to build a solar powered night light.  What I would like is to have it charge during the day and automatically come on when it senses darkness.  Here is what I've gathered so far, any suggestions are appreciated: 3AA rechargeable batteries (3.4V) 1 4.5 volt solar cell 1 phototransistor 1 transistor 4 White LEDs (20ma) This is my first posting and I'm a (near) complete novice to electronics!  Can anyone tell me if the photo-transistor or transistor needs a resistor and if so which one??? What resistor do I need for my LEDs??? How do I wire it so that my solar cell can recharge my batteries but not ruin my LED??? Thanks again and please feel free to chime in with your two cents =)

How do I prevent my great solar idea from being patented?

I have solved the solar energy crises by connecting linkages on the ground in a matrix pattern with a mirror on each small  plastic linkage, that all move in the same fashion. 30x30 m grids can focus all their energy on a single thermal element. My problem is that I don't want to publish this only to have  some company patent the idea and deprive humanity of energy. What now?

Solar Energy

Hi, i would like to ask for opinion, i am building a solar system where my system start from using a fresnel lense to collect the sun and use it to heat up a boiler, the boiler transfer steam into my tesla turbine and the turbine will turn my generator to produce electricity. Do anyone have any idea of building an own boiler instead of using a pressure cooker that i had seen this idea in somewhere, And, is there any places can provide cheaper fresnel lense as the sun focusing tool?? i will need a cheaper price lense cause of shortage in my budget of my final year project...

Solar cells and the environment

Question about solar cells. Since solar panels are encased in glass or polycarbonate, does exposure to the elements degrade solar cells? And if so, in what fashion? Corrosion of the traces? water infiltration? etc. etc? Or is it a matter of the fragility of the cells?

Arduino with solar panel

How can I charge 12V Li-ion or lead acid batteries using a solar panel? I also wish to interface the three, i.e. the Arduino, the solar panel and the battery, together so that the Arduino is basically driven by the battery but as the battery discharges, the solar panel would charge it. What circuitry do I need? Also tell the specifications of the solar panel.

Is there a way to use Solar energy to power an attic space

I am wondering if there is a way to use solar energy to power a room through solar power.

Solar Power Kits

Another Big Update! We've come a long way since 'How to Build a Qwik-Solar' (Over 9,000 views - Awesome!).  Qwik-Solar has now 'grown up' and become the iPower Station, producing more power - with easy to assemble frame kits and complete power packs. They can charge any power  pack with a 12 volt outlet and include key safety features (switches and fuses) for worry free use.  We've made it one of the best portable solar generators which can be used for cookouts, camping, tail gate parties, and emergency power. For industrial mobile solar power - We've teamed up with McGivern to provide solar Work Pods - with up to a 1,000 watt array! Last, we have Suntigo micro-grid kits for homeowners (with exciting news coming soon on new systems!)     iPower Stations are available from 45 Watts up to 85 Watts, with or without a power pack. Find all our solar generators here: Solar Mak And Thanks to everyone that's made Qwik-Solar such a success!

Solar Generator Kit

We're now offering solar panel kits - 45 watt, 65 watt, and 85 watt - when combined with a battery pack makes a great solar generator for emergencies or for fun. Solar Pax generators are the 'bigger brother' of the Qwik-Solar.   Solar Pax has very minimum assembly - and everything is already wired with quick connects.  Use to charge any battery pack with a 12 volt outlet.  We make these kits in Ohio. We set up a 'Mini-Catalog' on our website to make ordering easy. And we put together a page on our other site "Lamp Light from Sunlight" you might enjoy - it shows a 'Solar Pax' from 1954.   Update:  We've changed some domain around to better reflect our solar generator line up - the 'lamp light from sunlight' link above is active again.
