Q:Solar panel wiring trouble.?
. You want series, not parallel. (Add the voltages. Coonect '+' of the first to '-' of the next, and take your feed from the extreme ends.) 2. if you parallel them and you get less voltage than one alone, you got your polarity crossed up and are reading the difference between them.
Q:solar panels and batteries?
If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK
Q:Cost of Solar Panels for basement?
If you're really planning on solar energy, don't waste it on your own consumption. The Hydro company pays you for the energy you put back into the grid....the strange thing is, you buy the power back for less than you sold it, so you actually profit on the power you make! look into this. I wired a nice house for a doctor, and although I didnt supply the solar system, I learned of this concept there. The guy who installed her system charged her around $40,000.00 and the system would never be able to run any large portion of their home. They, of course sold the energy to the utility.
Q:how many 45 watt solar panels would I need?
I doubt you will be able to get anywhere near the amount of light needed to run anything for 6 hours a day. You will probably need a battery or something as well. At the least, you will need 3 solar panels, but you will probably need more than that in order to charge the batteries to get it to last long enough.
Q:how to built solar panel?
Building a good solar panel can take you up to a week. To make a solar panel you will need detailed guide including schemes and so on.... There are many guides at the net, but they're not free so you'll have to invest some cash. Typically such guide might cost at about $40 - $90 One of the best is Earth4energy: If you are interested you can read detailed review of this product here:
Q:How do Solar Panels work, and how it can generate electricity?

Q:is it worth it to install solar panels?
In the state of Pennsylvania in the USA, a very basic 5KW solar installation will cost you $35,000. Of that you will recover approximately $28,000 over the next five (5) years between the State and the Feds. Making your net-cost something between $7,000 and $9,000 depending on various factors. All other things being equal in a standard household with fuel-based heat and window units vs. central AC, this system will provide roughly 50% of power required with a payback of approximately eight (8) years (with electricity at $0.4/kwh). The system has an estimated forty (40) year service life. Without _all_ the subsidies, the payback is longer than the estimated system life, especially if you consider the time-value of money. The life-cycle cost of a photo-voltaic array is horrendous. By that, I mean the total cost of producing the panels, installing them, and then removing them and disposing of them in an environmentally correct manner. All that added in and there is a negative payback. So, it all depends on what one defines as worth it. Putting the cost onto taxpayers via governmental subsidy to make an otherwise wretchedly expensive process viable may give you all sorts of warm-and-fuzzy feelings about renewable resources and reducing dependence on foreign oil and so forth. But the reality is that the true cost of solar panels exceeds that of nuclear power per KW delivered. Even today when nuclear plants start in the Billions-with-a-B in any currency you would care to name.
Q:Do solar panels keep a structure cooler?

Q:i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
you need to have a voltage regulator on the gadget. That suggested, i imagine you're literally not giving it sufficient time. The battery might want to convey the voltage all the way down to its element. it is merely you attempt to replenish a huge reservoir with an eye fixed dropper. Bringing the voltage down would not help both. That lowers your ability.
Q:How to connect solar panels to batteries?
20 volts is a common open-circuit voltage for nominal 2v panels. The panels put out about 5v at full load. If the panel puts out little enough that it takes 20 hours or more to put a full charge in the battery you can get by without a charge controller - just keep the cells topped up with distilled water. A charge controller will do a more efficient job, though. The most efficient charge controllers use what's called Maximum Power Point Technology (MPPT) which lets the panels operate at their most efficient point throughout the battery's charging cycle. Available on OKorder. The charge controller should have the same or higher wattage as the panels it controls - if you're not sure of wattage, assume that they are the same as similar area panels you find for sale. Before buying a charge controller, connect the panels through an ammeter to a discharged battery. They may have been trashed because of damage and low output. You need at least an amp for trickle charge, 5 amps for reasonable recharge times.
