Q:Information on making solar panels?
I doubt that you are going to want to learn how to dope your own silicon wafers, add contacts and laminate them into PV panels.  I also doubt that you're going to even want the various chemicals to make e.g. cadmium-based cells anywhere near your house (cadmium is a very toxic metal).  In other words, making your own solar panels is not an at-home project. You can buy solar panels based on cells of several different types.  A link to a Pricewatch-like website for current prices on solar panels is below.  Mounting panels to roofs or pole mounts, running conduit and wires, and installing battery banks and inverters are within the capabilities of skilled laypeople. More data at the links. Edit:  I am reporting all of Agua-Luna's cut-and-paste pieces as spam.  I encourage others to do likewise.
Q:Solar panel trouble?
solar panels for those lights provide the power directly to the light, so there is no capacitor used or needed. in any event, capacitors very rarely break but you would need an OHM meter to test it.
Q:hi i am asking about the life of solar panels?
Some are better than others. It depends on the manufacturing technique. All will degrade over time, some over decades, others over months (if they're defective).
Q:Why do solar panels burn out?
You can search on solar panel failure mechanisms for scholarly works. Amorphous silicon thin-film panels go through an annealing, and power drops off after a couple years. This includes most of those flexible rubber mat type panels. That's why those are not used on serious installations. Serious panels intended for rooftop service generally come with a 25-year warranty, suggesting that the technology is more reliable than your washer, dryer, TV, computer, dishwasher, or water heater. One brand of panel had trouble about 0 years ago, but the manufacturer replaced all that were turned in, even paying shipping both ways. It was a problem with that particular model, not the technology. Our polysilicon panels have been on the roof for 3 years, now, and I've seen no sign of wear, yet, either electrically or mechanically.
Q:are there solar panel that work without the sun?
No. Solar panels require light to work. The closest type of passive energy collecting device is a thermocouple, which generates electricity via a temperature differential. But it requires a cold and hot source to operate, while a solar panel only requires light. Good luck!
Q:Could solar panels contribute to global warming?
Essentially, solar panels are 'warming neutral'. They absorb energy that would otherwise have heated whatever was behind them, thus have a local cooling effect. This is balanced by the generation of heat when the electricity is used to power, say, a hoover, TV, computer etc, also from 'transmission losses' through the national grid network. Good answers from Claire and Linlyons, bizarre answer from Jim! Tomcat may have a point though...
Q:How to prepare solar panels?
The following guide is the best DIY guide to build your own Solar Panels. the guide include step by step instructions + video. To Your self a favor and invest on buying this guide (it will save you a lot of time money) tiny.cc/solar55
Q:how does a solar panel works?
The fourth answer (kinetic energy) is totally wrong except for follow the instructions If you don't have the basic qualifications, you shouldn't even try besides falling off your roof and electrocuting someone else with bad connections. Solar panels produce low voltage DC power (up to 48 volts depending on design) which can be used directly but rarely is. DC power is stored in batteries for night, overcast days, and times of higher usage. The battery power must be fed through an inverter to produce 20 (or 240) volt AC power that your appliances use. The inverter to house connection must be made in a way that when the main power is turned off (like for repairs) your solar sourced power is not on the wires to hurt someone.
Q:What is the principle and structure of solar panels?
Solar power generation system consists of solar cells, solar controllers, batteries (group) composition. If the output power is AC 220V or 110V, also need to configure the inverter. The role of each part is
Q:What direction do solar panels usually point?
South in the northern hemisphere. - this gives you sunlight on the panel a major portion of the day without the need for a mechanism to follow the sun or change direction from E to S to W as the day progresses
We introduced the newest production line, testing machine, laser cutting machine, non-Pb soldering line, module testing machine, laminating machine and so on. We use top-quality solar cells and EVA,TPT,strengthen glass,seal silicon etc. Our experienced staff work together well to assurance quality under effective ISO system.
