Q:How to prevent shorting out solar panel?
A solar panel doesn't store energy. As soon as the light stops, the current stops instantly. If it's a 200-watt panel or more, it won't be harmed by a short circuit, but it might be good to turn the panel over or cover it with cardboard before working on it. The spark can slightly mar the contacts. Doing the work indoors is enough to cut down the current, too. For a 60-watt panel or less, I wouldn't even worry about the spark, the power output is too low to do any damage.
Q:Air conditioner 25 volt 5 amps: how many solar panels and batteries to run 24/7?
OK, in addition to the solar panels, you wil need an inverter (DC to AC; 2V t0 20V) capable of delivering 20A continuously and as much as 40A for the compressor starting surge, and a fairly large battery bank capable of delivering something over 2000 watts continuously (losses in the charging and conversion process) as well as the surge. So, if your actual demand is now calculated around 2000 watt/hour, and you need to both run the unit and charge batteries during the daylight hours - and considering that the ideal charging rate for a lead-acid battery is on the order of 0% of its capacity, you will need a huge reserve on the battery section and a huge excess on the solar section to make up for the 5 hours maximum input. So, the average high-quality deep-discharge battery will do about 400Ah @ 2.6V. Which comes to 5040 watts for one hour. For round figures, it will give you 2000 watts for 2.5 hours. You will need a minimum of eight of them just to make your system run for the 9 hours you are anticipating. Given that you do not want to run the batteries to zero each night, a 50% reserve would be a wise investment - comes to now twelve (2) batteries. Now, you will have to make 2000 watts (to run the unit) and also produce and another 8600 (per hour for five hours) watts to charge the batteries for the next night. Again, for round figures, you will need 0,000 watts of solar power, or seventy (70) panels. At ~0 watts/s.f. (00 watts/meter), that comes to about 000 square feet or 00 square meters. Modern non-crystaline panels may reduce this by 20%, or so but no more than that. You will be charging the batteries at roughly 20% of their discharge capacity - which will pretty much cut their service live in half, or so. As the average deep-discharge battery has about an 8-year life span under ideal conditions (and your situation will be far from ideal) you may expect to replace them every four years or so with good care. Much less with no care.
Q:Cost of Solar Panels for basement?
Only after you give an estimate of the power consumption you will have in the basement. Obviously you do not have a clue about solar panels or their usage. Suggest you find a book and start reading.
Q:Where are the best places to put solar panels?
The best place is where they get the most sunshine. Naturally they will be exposed to rain and snow.
Q:How do passive trackers work (for solar panels)?
It appears to be relying upon a phase change of liquid to gas to liquid to balance the system and return it to the east in the morning.
Q:Amount of solar panels needed to run a/c and pool pump?
Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
Q:Which is the least expensive, yet still very efficient, type of solar panel?
image voltaic thermal or warm water beats PV or Photovoltaic on a daily basis. The Mono and Poly are the main conventional. they provide years of provider and function a shown song checklist. they do no longer seem to be very warmth tolerant. production will flow down on warmer day as maximum shrink sheets will instruct. Amorphous Panels are greater warmth tolerant. they're additionally greater valuable at production with ,low easy or in part cloudy days. They produce much less what in keeping with sq. foot and want a larger section. First image voltaic produces those variety of panels. HIT by utilizing Sanyo blends those 2 together to produce a panel with the main suitable of the two structures. All PV is costly. The payoff tiers from 7-2 many years in keeping with many components.
Q:Can one benefit from solar panels?
Excuse me,Brack but you are totally wrong. Solar panels are not used only for demonstration or experiments.Some of the top corporations around the world use solar panels to great effect.On edit. A short search turned up many stories about practical use of solar panels all over the world.Perhaps you need to brush up on what's going on out there in the real world.

Q:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
