Q:Advice on Solar Panel....................................?
We put in photograph voltaic panels before this year, for the final six months we've became on our oil fired boiler approximately seven circumstances, for an hour every time. we are living in north Scotland. Our panels are for water heating only, they comprise fluid which passes by our warm water storage subsequently elevating the temperature. For a 4.4m panel and a greater complicated than regular setup it cost us £3500 alongside with labour. even nevertheless i've got faith you're thinking approximately panels for producing electricity? wherein case that form of photograph voltaic panel is woefully innefficient in this u . s . a .. i could advise to everybody to in effective condition photograph voltaic panels for water heating, it has stored us a fortune so a procedures and might pay itself back in approximately 5 -0 years depending on oil expenses. For electricity era nevertheless? no longer cautioned. As for grants, as quickly as we utilized we've been informed that all the supply money were used up and that became into that.
Q:how many 45 watt solar panels would I need?
I doubt you will be able to get anywhere near the amount of light needed to run anything for 6 hours a day. You will probably need a battery or something as well. At the least, you will need 3 solar panels, but you will probably need more than that in order to charge the batteries to get it to last long enough.
Q:Build your own solar panel, scam or truth?
Electric panels are not feasible for most people. They are two super thin layers of polarized material. When the sun hits them electrons move from the first to the second layer with an amount of force. You can't duplicate that at home. What you could do is setup solar heating panels and run them against a Stirling engine. This technique is typically more efficient than normal electric panels anyway in industry. They have heat on one side and cold on the other to generate force. Hook that to any generator to produce electricity. If you are successful building a home system, blog about it, others will want to know precisely how you did it.
Q:how much money do solar panels cost?
There are a lot of factors to consider. Net metering, utility rates, number of hours of daylight, size and orientation of roof or other location. I can tell you I had a 3.74 kwhdc system which reduces my bill by about $200 a month. It cost $26K installed, I received a $0K rebate from my utility and a $2K federal tax credit. Businesses have always been able to get a 30% fed. tax credit, this year everyone gets it. If this is a business you plan on owning for a long time there is no reason why you can't do the install in stages. Of course making sure you are conserving as much energy as possible will also help. Using energy efficient lighting, appliances and electronics, Turning off lights, monitors, computers, printers etc when people go home, sharing printers and other resources, adjusting the thermostat and using natural light can all help reduce your electricity usage.
Q:Can I hook up a Solar Panel to a car battery? Does it matter the kind of car battery?
A 2 volt battery is a 2 volt battery. Some are larger than others. Sure you can charge a car battery with a solar panel, but 00 watts for a long time could be a problem. There's one way to find out.
Q:Question about home solar panel systems?
There okorder.com Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:Can I get free solar panels?
If you sent payment via the US mail, report them for fraud. Next, solar panels usually have a high upfront cost for the homeowner - but this is usually offset by a tax refund. The amount of refund varies by area. Check out the cost with a local installer - they have the most motivation to know all the tax breaks you can get. Then save for it, and in the mean time switch your bulbs to fluorescents, unplug your coffee pot, computer, VCR, microwave when off, and see if your energy company provides free insulation evaluation services. And reduce your temperature this winter by 2 degrees, and change that furnace filter.
Q:What is the principle of solar panels to convert solar energy into electricity?
Solar cells are a pair of light response and can convert light energy into electrical devices. There are many kinds of materials to produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium and other copper. Their power generation principle is basically the same, now the crystal as an example to describe the process of photovoltaic power generation.P-type crystalline silicon doped with phosphorus can be N-type silicon, the formation of P-N junction.
Q:Solar panels for home info?
Of the practical technologies, crystalline silicon is still king. There have been improvements in manufacturing efficiency and price, but the fundamental technology is unchanged. For the past couple decades, there have been startups claiming that they will have a breakthrough available in 2 years, but so far, nothing has beat crystalline silicon for general applications. The appeal of thin-film was its cost, at the penalty of efficiency, but when the prices of crystalline plummeted, the cost argument went away. That wasn't the only problem Solyndra had, but it contributed to the company's demise. Organic solar cells show promise, and might ultimately be very cheap to manufacture, as they don't involve the high-temperature processing that semiconductors do. The main problem today is that they're not stable at the temperature of a hot roof. But then again, a few years ago, organic LEDs were the same way, and now they're commonplace in big TV's. Only time will tell. From a homeowner's standpoint, the install is routine, but still best done by professionals. It's like putting a new roof on a house, or wiring in central air conditioning. For most, it's better to call a pro.
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.
