Q:solar panel installed house roof?
How does the cable wires stay on the solar panel? With wire retention clips (4 per module) that are used to wrap the wire on the underside of the module frame. The home run cables to the transition box (converts between types of wire with no electrical transformation occuring) or combiner box (joins multiple source circuits in parallel, with the positives fused for safety) are usually tied along the racking system components, and with conduit sections used as needed. Racking is another big part of the installation. Don't just make your own homemade wooden rack, as these will weather away to nothing very easily, and cause great failures. GET a professionally designed metal racking system. PV modules are EXPENSIVE. Don't let the racking system cause them to break. It also requires the inverter, if you intend it to connect to the main electric service. If using multiple inverters, you need an AC combining panelboard to join them prior to entering the main electric service. Otherwise, you need to think about how else you might be using them. If you are charging batteries, you need a charge controller.
Q:how to build a solar panel?
Search Yahoo Answers or the internet first, this question is common. It is possible to build a solar thermal panel, to heat either water or air. You can just search YouTube to see how people did it. Try searching solar water heater. If you build a photovoltaic (solar electric) panel on your own, it will only be good for demonstration purposes. The homemade type I've seen produces only microamps of current - not even enough to run an iPod. Be wary of sites advertise you can make your own panel for less than $200 (or some figure), and try to sell you the plans. This is the same information that is posed on other sites for free.
Q:Do it yourself Solar Panels?
I okorder.com The cost of a solar panel goes up as the power or wattage does. It takes more cells to generate more watts. We are building a Solar Power Concentrator to focus more sunlight onto our solar panels.
Q:How much maintenance do solar panels require?
I'm okorder.com/... . That means that not only do they guarantee the panel won't completely die, they guarantee that it will deliver a certain amount of power. That suggests that manufacturers expect most panels to last longer than 25 years. Our panels have been up a little over 5 years - no trouble yet. In a dirty location, or where the panels are mounted flat, occasional cleaning may be required. In many place, the morning dew and slant of the panels is enough to keep them clean. In my limited experiments with our panels, I saw little difference in power production between a panel that appeared dingy to the eye, and one that was just cleaned. There is a component called an inverter used in most solar power systems. That generally has a warranty of 0 years, so expect it to break after 5, to be replaced at a cost of a few thousand dollars. Or maybe repaired for less. The kind of solar power popularly installed today does not use batteries. Batteries are generally only for remote installations that did not have grid power when the solar was first put up.
Q:Solar panel help please?
If you do decide to install your own system, get the current set of electrical code books so you know how to install the system in a manner that will pass the code requirements, which is required if you wish to have or keep insurance on the house and contents. Solar is not the complete answer in many places, in some places wind and solar together provide adequate power- but many municipalities do not permit wind turbines, and in some instances for good reason- some experimenters use the blade materials, like PVC which can break rather easily and be quite lethal. You tube has a number of blade failure vids.
Q:Need Large solar panels. ?
Just google search solar panels or pv panels and you should get a long list of them. That's what I did. Most of the sites selling them will also have the inverters etc that you'll need. Most likely you'll put several small or medium sized panels on your roof - as opposed to just one large one. You probably won't be able to run an entire cafe off of photovoltaic panels, even if you have a bank of batteries. Too many appliances running at the same time. Ask your electric utility company about net metering - you'll buy juice from them when your demand is high and sell to them when your demand is low - IF you can find a sunny day when you're not using juice, but if you have a restaraunt-sized refrigerator you probably won't be selling as much as you're buying. In effect, it won't eliminate your elec bill, just make it a bit smaller. Either way, you may be looking at spending $20,000 to cover the roof with PV panels and your savings won't pay that back any time soon. So, PV is not so great for a business. Much better for a home where you'll be at work all day the only appliances running in your house is your frig. Whatever you invest to solar your house will be repaid when you sell it, meanwhile you'll reduce your bills dramatically, especially if you convert all your indoor lighting to LEDs. On the other hand, the Googleplex, Google's office building full of computers, covered their roof with pv panels and claim to have reduced their monthly bill by /3. BUT, that's a huge building with lots of roof space.
Q:Amount of solar panels needed to run a/c and pool pump?
Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
Q:How do you connect solar panel?
You need a charger Controller but 55 watt panel is not a whole lot of power. So yes you can buy a very good one but it will cost a lot more. For a 55 watt panel you only need a 4 to 7 amp controller. But why not buy a 0 amp so you can add a second solar panel etc... A PWM (Pulse Width Modulated) is the cheapest and most robust type MPPT (Maximum Power Point Tracking) These controllers actually detect the optimum operating voltage and amperage of the solar array and match that with the battery bank. The result is additional 5-30% more power out of your array versus a PWM controller So unless you have a system over 200 watt the PWM works very good I have two of the PWM myself
Q:I want to buy solar panels?
You're unlikely to 'save a buck' much less 'make any money off of it' at the present state of the art. The panels and equipment will cost more than you'll save in the next ten years. That might change with energy prices, but not enough any time soon.
Q:SOLAR Panels?
I'm in the California Foothills and the island of Mindanao... I have both solar panels (electric and water heating) and a single wind-generator since 2000. We actually sell power to PGE in California and are self-sufficient in Mindanao. NOW, I'm confused with YOUR math... you say the Rep. suggests a monthly savings of $35 (25% of $40) which would be $420 / year. If materials / installation are $8,000 less $2000 tax-credit: it would take 35 years to pay off $6,000 at $420 / year. 980 Kwh/ mo is some pretty heavy usage... I'd suggest trying to reduce that. CFT's, lowering your AC setting, no lights if NOT in room, un-plugging stand-by appliances, and upgrading insulation. At our 2000 sq ft California RANCH we only burn 400 Kwh per month, and that includes an 800 sq ft barn (admittedly we heat with a wood-stove). We have 5, Sanyo 200 watt panels (3kw total) and generate an avg 900 kwh / month. SO, we're selling BACK almost 500 kwh mo. to the grid on the photo-cells alone. The kw wind generator averages another 20 kwh / month. I THINK the company YOU are working with is selling the EXCESS electrical-power back to the power-company behind your back !! GOOD LUCK
