- Q: I'm from Toledo, OH about 2 miles from the MI line. We are a foster family and have adopted 5 children. We just moved into a 5400+sq 2 story home. We have (3) 2.5-3 ton AC units to cool this huge house. We got the house cheap...$75k couldn't pass it up! Anyway...I was wondering how many solar panels it would take and of what wattage to power these Central Air Units and maybe the rest of the house. We have 3 people in our home......9 of which are children who leave the lights on and run hot water to beat the band. We have all brand new energy star appliances and front loader washer and dryer. Gas Range and Gas hot water tank. Was thinking of using metal window frames and buying solar cells and making my own panels. Just don't know how much to buy. We face south with no trees. Constant Sun. thanks for your help. An e-mail address to bounce questions off of would be helpful if you experienced. tx.
- Yes and no. solar panels are expensive and inefficient. therefore the power you generate will cost many times what the same power from a power plant would, and therefore you generally can only run a few low powered things at once. Secondly they don't generate electricity at night so you need some means of storing the power. tht means even more efficiency losses. They also only generate DC power, so you have to run the power through an inverter to make 0V AC. inverters are notoriously inefficient and expensive as well, so now you've thrown even more power away converting it. Bottom line, you're gonna pay far more than $600 a month for these things and you won't get nearly the amount of power you think. it is generally a waste of money to do this in almost all cases. The ROI is usually well over 20 years before you break even.
- Q: How do solar panels affect the local job market?
- Solar panels can have a positive impact on the local job market. Their installation and maintenance can create new employment opportunities in the renewable energy sector, leading to job growth. Additionally, the development of solar farms and manufacturing facilities can attract investments and create more jobs in the local economy.
- Q: I would like to know of any construction companies, road crews, or any company that uses solar panels in the Tampa area and throws them away. I like to recycle solar panels by repairing and processing what power I can from them. Know any companies that throw out used solar panels? If so, can you provide the name and number?
- Used solar panels are usually a great bargain. Unless there is obvious major damage, you are most likely making a very safe and thrifty purchase--and if you can test the panels with a multimeter in full sunlight before purchase, you are almost guaranteed a functional panel. Nobody really knows what the lifespan of a solar panel is, since many of the very first panels are still in operation. I have three very old Arcos on my house, and they are still performing well. However, used panel prices have
- Q: How do solar panels affect the electrical grid?
- Solar panels can have both positive and negative impacts on the electrical grid. On the positive side, solar panels help to reduce the demand for electricity from the grid, especially during peak hours when electricity is most expensive. This can lead to cost savings for the grid and reduce the need for additional power plants. Additionally, solar panels generate clean, renewable energy, which helps to reduce greenhouse gas emissions and combat climate change. However, the intermittent nature of solar power can pose challenges to grid stability and reliability. Fluctuations in solar energy production can create imbalances in supply and demand, requiring grid operators to carefully manage and integrate solar power into the system. Overall, solar panels can be a valuable addition to the electrical grid, but their integration requires careful planning and management.
- Q: What is the average annual energy output of solar panels that can be installed on the home?
- The Sun provides about 360 W per square meter above the atmosphere (Solar Constant). Approximately 2/3 of the energy is lost in passing through the atmosphere, which means you should anticipate at best about 450 W per square meter arriving at a solar panel directly facing the Sun on a clear day. You can anticipate an efficiency of approximately 30% for a typical solar collector, or about 00 W to 40 W per square meter of solar collector being delivered as electricity under the best of conditions. These are estimates, but we need better information on the actual power delivered per square meter of a particular solar collector under the best of conditions before we can begin to estimate the amount of energy per meter squared collected over a typical year for a given location.
- Q: How do solar panels impact the roofing material's lifespan?
- Solar panels can actually extend the lifespan of roofing materials. This is because they provide protection against various weather conditions, such as rain, sun, and snow, which can cause damage to the roof over time. Additionally, solar panels act as a shield, preventing direct exposure to harmful UV rays that can deteriorate roofing materials.
- Q: Can solar panels be installed on asphalt shingles?
- Yes, solar panels can be installed on asphalt shingles. However, it is important to ensure that the shingles are in good condition and can support the weight of the panels. Proper installation techniques and mounting systems designed for asphalt shingles should be used to prevent any damage to the roof.
- Q: OK, so if you put solar panels up on a roof, they are busy turning the sun's energy into electricity. So, does that mean the roof (and therefore the house/structure) stays cooler as well? Or does it still get hot, because . . . I dunno, maybe the panels don't convert all the energy, and the spillover still heats up the building.Any links or URLs to scientific answers would be appreciated, but I don't mind hearing from the Average Joe or (Joelle).
- I asked the same question once to a PV install during a seminar a few years back, and he explained the following: No, PV panels do not reflect or absorb much heat from going into the building below but there is a reason for this: PV panels that reflect / absorb heat produce less electricity. They are designed to Thermally Transparent. Even worse if installed incorrectly without a good angle and air gap to allow the heat to escape the panels will actually trap this heat and increase the interior temperature of the building below! Below is the scientific analysis that is quite verbose but has two nice graphs at the end. To summarize: Adding PV panels, at best, shaded the building enough to reduce the load of the interior A/C unit by .8 kWh/sq-m/year. The electricity generated by the panels was about 356 kWh/sq-m/year. You can see the big advantage of PV panels is to make power, not reflect heat. Proper insulation is much cheaper and will do a much better job. Don’t worry, I was shocked too, but like anything it makes sense after it is explained.
- Q: My solar panel is 24long..It is set at 45deg..the arms are 8quot;long to achieve that angle for winter. I need to get to 7deg for summer..how long will the new arms need to be?..in layman's terms please...thx
- You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav
- Q: Can solar panels be installed on boats or RVs?
- Yes, solar panels can be installed on boats or RVs. In fact, solar panels are a popular choice for both boats and RVs as they provide a sustainable and reliable source of electricity while on the move.
