Q:How many solar panels do you need on your house to power your heater in winter?
Your house, and probably your yard wouldn't be big enough to hold them. I did this exercise once (not doing it again) for someone who wanted to replace his 6hp outboard motor with a solar powered one. The calculations ended up that he would need something like .5 acres of solar panels to get that much energy. Not happening. That said, an passive solar home, can get a significant amount of warmth from the sun directly. But it doesn't work very well at night, when it's coldest. (wonder why that is... probably a climate scientist could help us with that? -- oh, wait. They say warming doesn't have anything to do with the sun.) Edit. I didn't use theoretical stuff to come up with my numbers, I used the claims of actual off-the-shelf solar panels sold by West Marine, calculated the power, and did the math based on existing panels.
Q:Increasing Solar Panel Efficiency?
Even the angle of a solar panel can increase it;s out put, if you point it towards the south, it will receive more light (or towards the light source if it is an artificial source) mirrors can also be place and angled around solar panels to gather and reflect more light to the panel, this is often done is solar water heating, but would work with a panel as well. Over all, solar panels are very efficient, it's our way of catching light that isn't.
Q:what is the volts of 75watts solar panel?
Many of the panels used on homes are designed to produce 2 volts DC. 0 of them wired in a series would produce 20 volts DC. An inverter is used to change the DC voltage to AC. The other aspect of electricity is amperage. With electrical units wired in series the voltage is added. When they are wired in parallel the amperage is added. The Volts x Amps produced will give you the wattage. A wise homeowner will examine their electric bills or the equipment used to determine their demand. They will consult tables that let them know how much sunlight their area receives each year as this will alter the rated performance of the panels. Then they will try and determine how much of the demand they want to fill. 80% may be economical. Then they also want to determine what they will do with excess electricity that may be produced during the summer months of intense sun and how they will supply the shortfall of low sun winter months. From all this they will determine the number of solar panels they need to purchase.
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:Can solar panels work in the shade?
The All solar panels sold by Energy Matters have bypass diodes, which send output from the remaining cells around that dead cell. However, you have lost the output of that cell, so the total panel voltage will drop by about 0.48 volts per cell. Most panels are in the 6 to 8 volt range, and most batteries need at least 3.5 volts to charge completely. So, if 2 or more cells are shaded, the output voltage of the panel may drop too low to charge the battery.
Q:Solar panels for security cameras?
Research using solar panels on stock tank water pumps. Same concept - you use a solar panel to power a remote something or other, only you would have to use a battery charged by day to run the camera at night. It does not look like you would need too powerful of a solar panel, the camera server says it needs less than 5w, no idea on the cameras, so check that out, but the whole system looks rather low power. You could easily get the necessary panels, maybe the battery too, for... I would say $200 (not in one package, you would have to get separate things). Connection of everything would be simple, no electrician needed (but keep that to yourself, depending upon state rules and regs).
Q:What should the voltage be on a small marine solar panel?
It has to be facing the sun for full power U check at the battery and it should increase as the sun hits directly on it. U can't check it at the panel after the diode.
Q:Who created the first solar panel?
The first photovoltaic cell was developed at Bell Labs in 954. The team included G.L. Pearson, C.S. Fuller, and D.M. Chapin. A panel is composed of many cells. They respond to a wide range of wavelengths, not just UV.
Q:Solar panel connectionI
The answer is that the two panels should be put in parallel. The voltage out will drop to the voltage of the lower panel, but you should get most of the power, if the panels aren't too badly mismatched. I would try to get a multimeter and try to measure the actual current coming out of the panels in full sun. Sometimes the specifications on these smaller panels are very optimistic. If the whole setup is putting out less than 2 amps, I'd say wire the whole thing straight to the battery - little chance of boiling the electrolyte at those currents.
