Q: How much money can you save by using solar panels?: The amount of money you can save by using solar panels depends on various factors such as the size of your solar system, your energy usage, location, and the cost of electricity in your area. On average, homeowners can save anywhere from a few hundred dollars to several thousand dollars annually. It's recommended to consult with a solar professional to get a personalized estimate based on your specific circumstances.

Q: I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!: I did the same thing recently, if you'd really like some free ones then you need to look for those little solar powered lamps that people put in their yards, theyre about 0 inches tall and people sometimes line the paths through their yard with them. Maybe you can find a neighbor who doesn't want theirs anymore, or you could check local dumps for them. They each have a solar panel in the top, and they can be linked together to make more power. Alternatively, you can look on OKorder for a pack of broken solar cells, which still work fine but don't put out quite as much power as they did when they were new. However, they are very cheap. Hope this helps.

Q: Can solar panels be installed on agricultural irrigation systems?: Yes, solar panels can be installed on agricultural irrigation systems. They can provide a sustainable and renewable source of energy to power irrigation pumps, reducing reliance on fossil fuels and lowering operational costs for farmers. Additionally, solar panels are compatible with various irrigation system configurations and can be easily integrated to support the water needs of crop production.

Q: I want to buy a solar panel kit to run my central AC unit. it is a 3 ton unit. Can I do this? The electric rates in the Chicago area are skyrocketing and I can't keep paying 350 dollar electric bills during the spring and summer months: It sounds like saving money is your chief goal. If your house is not already super-insulated, that should be the first target. Super-insulation, radiant barriers, double-pane windows, white roof, weatherstripping, attic fan. Number two would be conservation. Can you turn the A/C up to 80? I visited a place in Wyoming when it was 0 outside, and 80 felt very pleasant. Third, efficiency. Have you considered a ground-sourced heat pump? Deep down below your house the water table may be colder than 40 degrees F, and can provide good cooling. After all that, you can look into solar electric, which may or may not be a good deal in your area. The type of solar electric that is most cost efficient is the kind that connects right to the house wiring and works alongside the normal electric company. You can talk with a local installer and get a free financial analysis. Then you can look at it and see if the installer is on the level, or trying to play accounting tricks with unreasonable assumptions. Solar makes sense in most parts of California, but Illinois is not known as a big solar area. The kits you have have seen were probably for standalone solar, generally an expensive proposition for the amount of power you get. Put another way, either it will be low power, or it will be very expensive.

Q: I have a college project due within a week, and it involves a 00 Watt solar panel and a 2V 7.5Ah Battery. I got the project finished up and producing free energy for my house in September, however recently the battery I bought, that was specifically made to hold Solar Power, lost its charge (unsure how or why) and it is pretty much useless. Can I just go to a store and buy any 2V car battery to use?: Those answers are partly correct. You cannot recharge two 2 volt batteries in series with a photovoltaic panel with an open circuit voltage of 8 volts. You possibly over charged your 7.5 AH battery with a 00 watt photovoltaic panel, which can supply 8 amps to the battery with unusually bright sun light = fully charged in one hour. More likely you did not charge the battery for a month or more which killed it. Also discharging below 2.6 volts shortens the life of the battery, or short circuiting the terminals even briefly. Yes a deep cycle sealed lead acid battery rated 2 AH is likely the best unless you buy a 00 amp hour marine battery which weighs about 80 pounds and will take at least two days of bright Sun to fully charge.

Q: im trying to run my house with with solar panels, is it possible? if so please let me know how....i have a 6000 w inverter: In my opinion you can do it. You will need to have solar panels. and batteries to store the power until needed.

Q: How do solar panels affect the property's overall cost savings?: Solar panels can significantly impact a property's overall cost savings by reducing or eliminating electricity bills. With the ability to generate clean and renewable energy, solar panels offset the need for traditional grid electricity, resulting in long-term savings. Additionally, solar panels can increase property value and attract potential buyers or tenants, further enhancing cost savings over time.

Q: How do solar panels generate electricity?: Solar panels generate electricity through the photovoltaic effect, where sunlight is converted into electricity. The panels consist of multiple solar cells made of semiconductor materials, typically silicon. When sunlight hits the cells, it excites the electrons, causing them to flow and generate an electric current. This current is then captured and used to power various devices or stored in batteries for later use.

Q: I want to install solar panels in my roof and most installers don't recommend any particular brand. Do you have experience with any particular brand that has worked for you or anybody you know? Does the brand of the panel make a difference?: You don't say what you are doing. Are you trying to get electricity from them and need solar photovoltaic panels or are you trying to run a heating or hot water system and need solar thermal panels. It is unfortunate that both of these are known as solar panels as they are really two entirely different designs. Currently the solar thermal panels are more efficient and therefore have a quicker pay back period usually measured in lower single digit years while the photovoltaic panels have paybacks that are sometimes more than double that unless you figure in increased property values and state and federal subsidiaries and tax credits where available. Edit: Recent advances make any current investment in photovoltaic panels likely to be obsolete in 5 years. Still someone has to be on the cutting edge. Two currently available technologies are concentrating the sun's rays within the collector on a much small chip area.2 This improves the efficiency and lowers the cost as concentrators are cheaper than chips. The other option is newer chips that accept a wider spectrum of solar energy.3 This has the potential advantage of producing more energy on cloudy days. This may not be so important in your situation. Balanced against cutting edge technology will be the possibility of getting older panels at a less expensive cost. The bottem line will always be pay back period. More panels at a lower efficiency and cheaper price will be just as good as high efficiency at a higher price if the numbers work out. 4 Between two answers here you now have a criteria for selection and some recomendations. Good luck with your project.
