Q:Powering my house with solar panels?
I had a survey of my home and it was estimated at $30K with a 30% rebate from the government. It would take about 5 years to pay back the cost. I elected to go solar water heating instead. 2 panels with piping installed to an 80 gallon electric water heater with an internal heat exchanger. One small photo voltaic panel to run the pump. There is ethylene glycol inside the pipe and it circulates and heats the water. Works excellent. I live in Nor-Cal and we get a lot of sun. I need to comment on another statement that photo voltaic cells cost more energy to produce they generate. Maybe once but not true any longer. {Solar cells and energy payback In the 990s, when silicon cells were twice as thick, efficiencies 30% lower than today and lifetimes shorter, it may well have cost more energy to make a cell than it could generate in a lifetime. The energy payback time of a modern photovoltaic module is anywhere from to 20 years (usually under five)[9] depending on the type and where it is used (see net energy gain). This means solar cells can be net energy producers, meaning they generate more energy over their lifetime than the energy expended in producing them}
Q:How can I run my house purely off of solar panels?
In my opinion you can do it. You will need to have solar panels. and batteries to store the power until needed.
Q:How are solar panels developed and distributed in America?
The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.
Q:How to Compare Solar Panels?
Every okorder.com for links and faq's.
Q:Solar panel Efficiency in Tropics?
Duh - 000 W panel (rated in good sunlight) in 0 hours of good sunlight. Let me see - 0 * 000 = 0,000 wh or 0 kwh. Yup.
Q:adding more solar panel & battery?
That charge controller is notoriously cheap and burns up easily. If you are going add solar panels, also buy another charge controller to go with them. They can both be connected to the same battery bank. I don't believe the kit comes with batteries, so you would buy whatever size 2V battery bank your power requirements call for. The size of the inverter depends entirely on what you are going to power with it, not the size of the panel array. As long as you are not powering anything that is over the 300W rating, you don't need a new one. Just be sure to check the details of the inverter, is it 300W continuous, or can it handle up to a 300W surge? Also, it's a modified sine wave inverter instead of a pure sine wave inverter, so don't plug any sensitive electronics into it. They may not work, or you may get a buzz or hum from it.
Q:how often do you have to replace solar panels?
solar cells never really stop producing, they just reduce their output over the years. There are many solar panels still running at 75% of their initial output and have been up for over 40 years. Most manufacturer will give you a 25 or 30 year waranty. That means that they guarantee that the solar panels will have no less than a 0% drop in the amount of electricity produced by each panel in 30 years.
Q:Connecting solar panel help?
never hook up solar panels in series, you reduce the total power produced, and may hurt them, only voltage out, never voltage in. Don't forget to vote for best answer!
Q:2v vs 24v solar panel?
The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.
Q:Good Idea To Install A Solar Power Energy On A Restaurant?
Different solar companies install these panels. Check your local area for a free quote. If you don't already have a solar panels for a hot water system yet, consider a thermosiphon design, then you need no electricity to produce hot water. All the other designs require some electricity.
