Q:How to charge a Battery with Home Electricity and Solar Panel together?
connect the solar panel to the Battery direct during the day time that's how it works in ALL situations !
Q:How much energy does it take to make, install, and eventually dispose of a solar panel?
At present the technology to create silicon solar cells is incredibly energy intensive. It is not logical to compare the cost of oil to the cost of a solar cell because they are not priced according to energy input. Oil has a strong advantage in that it is concentrated solar and geothermal chemical energy that has accumulated over millions of years. The price of oil does not reflect its energy content, but the cost to retreive it. Electrical energy used to produce a Photovoltaic cell is not priced in any proportion to oil. By some calculations it will take about 50,000 KWh of energy produced by the PV cell before it can recover the energy used to manufacture it.
Q:Build your own solar panel, scam or truth?
What I've heard, is that for those sites implying that you can power your house and save money with homemade solar panels, is that if you try to get your money back, there is no response. Maybe if you used a real credit card, you could dispute the charges through your credit card company. Actually, I wouldn't be worried about buying materials and it not working - the more likely scenario is that you would get their instructions, and realize that they're practically worthless. In Florida, you have a chance to save money on your electric long-term, but it will be by investing maybe $0-20k, and then getting that back after 0 or more years. I'd suggest you contact a local solar installer and get a bid, even if it's only to scope out how much it would cost up front. Then you can shop around and see if you could save by installing it yourself. It's a serious project, not to be taken lightly. It took me about 3 months to put it up. It's possible that you will not save money by self-installing, as professionals may get better prices on the panels. The Florida state rebate is subject to availability of funds, and typically, I've heard people wait a long time to get it. The Federal rebate is a credit to your taxes, so you get it the next year.
Q:Can solar panels be connected directly to motor?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on.
Q:is it worth it to install solar panels?
If okorder.com and I mention them only because they did a retro fit on my Uncle's house in the Florida Keys and a smaller scale system for my in laws outside of Chicago. Both my Uncle and In Laws really are enjoying the cost savings that they are getting each month from their respective systems, and both said that Sun's initial costs were QUITE low. Be sure to have the blessing of your local building zoning departments before installing the panels as some municipalities take issue with solar panels. Also make sure that your roof is strong enough to withstand the weight of not only the panels, but the bracing. Good Luck.
Q:What is the working principle of solar panels?
No matter what kind of material to make the battery, the general requirements for solar cell materials are
Q:When you get solar panels do you connect them to the grid?
You okorder.com/ as they provide very accurate free solar quotes and break down all the incentives you will be eligible to receive, your estimated annual savings, your payback period, projected IRR, and a cash flow analysis. They taught me everything I know about solar, and I must say they're a great starting point if you're curious about what solar energy is all about.
Q:How do solar panels and their battery backup systems work?
First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
Q:what can i do with a calculator solar panel?
It wouldnt be worth your time really to try and hook it to a psp. You would have to build a circuit to match the voltage of the solar panel with the voltage of the psp. one of the few things i can think of would be a model windmill that used a very small solar panel to turn a very small motor attached to the rotor on the windmill. If you want a solar panel to charge your psp, look on OKorder, theres plenty of cheap low wattage solar panels that with a small solar panel regulator can put out enough 2v dc energy to possibly charge your psp
Q:How to connect solar panels to batteries?
a million. confirm you get carry of the suitable form of battery that permit to can charge from the image voltaic panel. 2. confirm you utilize a gadget which I forgot the call in spite of the fact that it's going to make confident the can charge pass one way in case the sunshine pass out so won't drain the battery at the same time because it somewhat is hook up. 3. confirm you get carry of the suitable can charge from the image voltaic panel to can charge the battery. reason is easyier to swim down the river or is it basic to swim up river.
