Q:Solar Panels Energy Theory?? ENERGY?
I haven't any theory what you're doing or what you think of you're attaining. A 235 watt panel isn't lots potential. you may easily save it with a undeniable previous lead acid battery.
Q:How to amplify current from a solar panel?
The previous answer about wattage is correct, so this is your first problem. Try increasing the number of solar panels by connecting them in parallel. To answer your question about increasing current, a voltage regulator wastes energy to regulate voltage. You need somthing that is not so wasteful, and that is a DC-DC converter. You will need to buy a 20V-5V model. this will give you less voltage but more current than you origionally had with your solar panel. You can alter voltage and current capacity, but you cant increase power (watts) with a DC-DC converter.
Q:Solar Panel costs and sizes?

Q:How do Solar Panels work?
Light consists of small packets of energy called photons. When photons with sufficient energy strike the photocell its energy is converted into electrical energy which is stored in the batteries as dc voltage. To run a TV an invertor is used which converts dc to ac. Now you can make a block diagram of it and present it TC
Q:Solar panel technology?
It isn't really that simple. First you have to decide if you are going to use it after dark and in cloudy weather. If so you are going to need batteries to store power. You are also going to need an inverter to convert the direct current, low voltage power to 20 volt alternating current. Once you have made those decisions you need to determine power requirements. Look at the back of each piece of equipment and find the wattage rating for the device. Add them together and you will have a starting point for power consumption. Since you will want to charge the batteries during daytime and you have parasitic drain from the inverter use you want to increase that number by 50%. When selecting the number of panels you want you have to assume they will not operate at the optimum they do deteriorate over time so de-rate them by about 50%. Once again, look at the data plate to determine wattage and get enough panels to meet the power requirements using the criteria I have mentioned.
Q:what is solar panel? full description needed?
Solar panels are devices that convert light into electricity. They are called solar panels because most of the time, the most powerful source of light available is the Sun, called Sol by astronomers. Some scientists call them photovoltaics which means, basically, light-electricity. A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going. DS's solar cells are even more efficient than regular solar panels made for satellites because they use solar concentrators.
Q:What do I need to install a 40 watt solar panel?
Your demand is high. You require at least 5KVA (5000watts) out put with an appropriate battery storage and inverter..
Q:Why did the voltage of a solar panel drop significantly after putting it through a step down voltage regulator?
you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
Q:Solar Panel Batteries?
If he is going to be running off batteries at night, he would be better off with traction batteries. Traction batteries are true deep cycle and can better withstand deep discharge. Golf cart batteries at Sam's Club (the other half of Walmart) are traction batteries. If your grandfather needs safe refrigeration, a mini fridge won't do it. A 0 fridge takes too much power to run off solar panels and most won't hold their cold very well if unplugged for long. I run a fridge off grid with hybrid deep cycle marine starting batteries. It's an Engel 40. The price has gone up over $00 since I bought mine. It's a real fridge with a compressor and freon 34a. But it runs on 2v dc or 0vac and only uses 36 watts running because of a special compressor design. It will freeze food if you turn the dial down to 2 out of 5. It can also deep freeze. I use mine to keep eggs, milk, cheese and fruit juice. Your grandfather would need 400 amp-hours name plate rating of batteries at 2v to run the Engel, and probably 00 real watts of panels to recharge his battery bank. The Harbor Freight 45 watt panel set only puts out 30 watts on a clear cool day. That won't do it.
Q:Solar Panel questions...?
I have a system that was installed last year. I have 20 panels which provide me with about 75% of my electricity. I do use less electricity than the average home. I use an average of 45 kwh in the summer, my neighbor uses more than double that. I paid $26K for the system, but I got a $0K rebate from my utility and the US gives a fed. tax credit. I am saving about $2K per year, so it will take just over 6 years to break even. I also have what I think is called net metering, my utility allows my meter to run backwards when I generate more energy than I use, so pretty much the entire time the sun is out in the summer. Having energy efficient appliances, reducing standby energy and using conservative climate control really helps keep my usage down. Weather striping, insulation and clean well maintained systems all help as well.
