Q:Do it yourself Solar Panels?
I am starting to think about solar panels as an option for my home. I have d fef one some research on panels, to be honest its all very confusing. There are many.   Read more...
Q:Anyone know if there is a solar panel that you can travel with that is not USB plug in ?
Solar panels require a charge converter before it can be used by an AC source. There is no direct solar panel with built in charge converters that I know of because, when purchasing panels, you must purchase the wattage requirements of the job (this can be several panels linked), and a charge converter that will handle the <? panels required. A chain of stores up here in Canada have a portable battery pack that has a solar panel to increase its charge capacity or duration, but its not something you would want to lug around for long periods of time, because is weights in about 3 lbs.
Q:Are Solar Panels worth it in Southern California?
With tax incentives, yea it's worth it. It will take years to recoup the costs. You need to live there for a while.
Q:How much Silver do we need for Solar Panels?
Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells. Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead. Generally the metal used is in small amounts and not a majority of the cost of the solar panel.
Q:Do solar panels keep a structure cooler?
I okorder.com
Q:How to make 2V 4.5A solar panel from solar cells?
To increase current, you connect the cells in parallel. But I think you really mean you need 4.5 watts rather than 4.5 amps of current. For an RC car, 4.5 amps would be huge, literally a regular car battery. So I think you mean you need a 2v, 4.5w panel. That would make more sense for an RC car battery. I went on OKorder and bought a 2v, 5 watt panel for about $30.
Q:how do i build a solar electric panel for my home?
you need to buy, not build. Just to put the parts together correctly requires a lot of experience, not something to be done by someone with no experience. And this is a major project, with lots of decisions before you start. how many watts? how many hours of sun do you get per day? worse case? Do you have a space to put the array where it can get sun all day with no shade? grid tie or not? how many batteries if not grid tie? if no grid tie, how long do you expect the batteries to last during a long period with no sun? And finally, how much money do you want to spend. for a good sized system expect to pay US$20k to 50k
Q:are there solar panel that work without the sun?
No. Solar literally means Sun. But...scientists are working on a panel that can absorb energy after the sun has set. It may be years until we see any commercial success.
Q:What does it mean when a solar panel is 00w?
The 00w panel puts out 00w at peak power -- full sun. You will lose some power as heat through wires and other equipment and also some will be lost when it's converted to AC, unless you will be using all DC appliances and lights, etc. I think a good estimate would be about 0 - 5% loss. You will also need to know your average solar insolation, average amount of full sun you receive at your site. This will tell you how many panels of 00w it will take to get you 5kwh/day. Don't forget your losses as per above and add a little extra for peak usage that is needed when two or more major appliances and power uses start at the same time. Hope this helps. I'm glad you're checking into solar and good luck.
Q:Solar panel trouble?
Most solar panels convert the energy collect from the sun directly into usable DC current. So no, you do not need a capacitor to test a light if you are in sunlight. You will need a capacitor or rechargeable battery if you plan on testing the solar panel away from a light source after the capacitor or battery has charged. Solar panels cannot store electricity.
