- Q: How can solar panels be integrated into building designs?
- Solar panels can be integrated into building designs by incorporating them into the structure or facade of the building. This can be done by installing solar panels on the roof, as awnings, or as part of the building's walls or windows. Additionally, innovative designs like solar shingles or solar glass can also seamlessly integrate solar panels into the overall aesthetics of the building.
- Q: Didnt solar panels use to cost around $250,000 5 years ago?
- For just 5 years ago, certainly not! Perhaps you are thinking of 50 years ago, the kind that was put on the early communication satellites? 5 years ago, there was a glut of polysilicon, so modules were actually a little cheaper than today. Solar cell makers were basically using the scraps thrown away by chipmakers. But today, more silicon goes into making solar cells than computer chips, so that bonanza is gone. We will see prices going lower this year, possibly 20% from last year, because of improvements in technology, but also an increase in polysilicon supply, and a slowdown in demand due to worldwide recession. Later this year is a good time to buy panels, if you have the cash. The industry site below tracks module prices. They used to have more data, but I guess the old data rolls off the screen with time. If you want to see the details, they'll charge you for the report.
- Q: If I wanted to add solar panels to my home to produce on average, 8 kWh of electricity daily, how much do you estimate it would cost using state of the art technology?I live in Virginia (Washington DC Metro Area), and I have Dominion Power. I pay the following electric rates:Jun-Sep $0.0904/kWhOct-May $0.0776/kWhAnnual Ave: $0.0824/kWhDistribution charges add on approximately another $0.0228/kWh.How long would the ROI for an 8 kWh/day solar system be?
- Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .
- Q: How do solar panels affect the resale value of a home?
- Solar panels can have a positive impact on the resale value of a home. Studies have shown that properties with solar panels tend to sell faster and at a higher price compared to homes without them. Potential buyers view solar panels as a valuable and eco-friendly feature, leading to increased buyer interest and willingness to pay a premium for a home equipped with solar power.
- Q: Can solar panels be used to power a greenhouse?
- Yes, solar panels can be used to power a greenhouse. Solar panels convert sunlight into electricity, which can then be used to power various electrical systems in a greenhouse, such as lighting, ventilation, heating, and irrigation. This renewable energy source offers an environmentally friendly and cost-effective solution for greenhouse operations.
- Q: Okay so.. if light deflect the light of the sun and black absorbs it, then aren't solar panels just absorbing more light, sun and heat into our atmosphere? Wouldn't this lead to an increase in global warming? Shouldn't solar panals be white? No rude answers please.
- There are two basic types of solar panels. ) Thermal absorbers 2) Photovoltaics Thermal absorbers are black in order to convert sunlight to thermal (heat) energy. The whole idea is to capture all of the light with a dark surface, convert it to thermal energy and transfer the energy into your home for water heating or space heating. If you make the surface white or reflective, then the surface will absorb only a small fraction of the available light, hence the efficiency will be very low. In other words, the panel will not produce any heat. Photovoltaic panels produce electricity instead of heat energy. Photovoltaic panels are made from thin slices (“waffers”) of silicon with special coatings on the front and back surface. One of these coatings on the front is an antireflection coating to capture the light and channel it toward the silicon. Underneath the antireflection coating the silicon waffer is coated with other chemicals that convert the sunlight to electricity. The combination of these coatings gives the panel a dark color, usually blue or black. Here's the bottom line. If you want thermal heat or electricity from solar panels, the panels have to capture the light. When that light is captured, the surface appears dark because no light (or very little) light is reflected back to our eyes. It is not possible for a surface to be an efficient absorber, capturing all available light, and at the same time appear white or bright color or reflective to our eyes.
- Q: Can solar panels be used for powering a farm or agricultural operation?
- Yes, solar panels can definitely be used to power a farm or agricultural operation. Solar energy can be harnessed to generate electricity, which can then be used to power various farm activities such as irrigation systems, lighting, machinery, and other electrical needs. By utilizing solar panels, farmers can reduce their dependence on traditional energy sources, lower their operating costs, and promote sustainability in their operations.
- Q: Maximum size of solar panel i have to use is - 8 * 5 feet - this is the limitation given to us.
- go buy some 90's Arco solar panels. they're about 2x5 inches and produce 60 watts (24 volts x 2 amps) in full sunlight. then mount them up on a rig that tracks the path of the sun all day long. not all solar panels are created the same. the ones you get at harbor freight will be less efficient than the ones you buy from some guy whose father got the panel as a gift from a business party in the 990s.
- Q: And how do you choose the best one for the best price?I saw a 400 watt monocrystalline solar panel
- In regards to my research about these two types of Solar Panels, I suggest that the Monocrystalline Solar Panel would be great! It is affordable and also more convenient to install. Using a 400W Panel means fewer panels and less installation time, in addition to fewer connections and transmission losses which results in big savings and a faster return on your investment.The Topsun Solar Panels boasts efficiency of up to 6.77% and use cutting edge technology for the best heat dissipation in the industry.
- Q: a fiber optic network could distribute solar energy from warm states to the rest of the country. Using a Federally created program,the energy would be used through a trust program to benefit all of our citizens equally. It would create thousands of jobs and help us with our dependence on foriegn oil supplies. This is no different than work programs created by the Feds during the 930's depression era.
- To add to what others have said, more importantly, what will you do at night !! Electricity is VERY hard to store, so it has to be produced all the time. Even cloudy days cause problems. Lack of raw materials, costs compared to other forms, and the fact that miles across will not even be close. Think more like a state across to supply the US. Think avout this yourself or ask your parents if you are younger. To go solar are you willing to have your power bill be 0-20 times the current level for the next 30-50 years? You will find the answer in NO. I think those numbers will even be conservative. On your depression argument. Remember that the unemployment rate was 7% where it is 5% now. Also, the real end of the depression was WWII. I hope we don't do that again. Can you imagine trying to double federal spending? I don't think taxpayers would go for that. Start in your own back yard. Become energy efficient yourself. Install solar, use an electric car, and do everything you can before you spend other peoples money.
