- 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: The first panel is located in New England, the second is placed in the Sahara desert, the third is on the Earth side of the moon, and the last is on the far side of the moon. Which panel would absorb the most sunlight over a year's time and why ? All the panels are place in optimal places where they would get the most light available.
- They all face the sun about 50% of the time on average over the year. Best: far side of the moon, 2nd near side of the moon; because in the first case the panel is a moon-orbit-diameter closer to the sun at time of exposure. I think the Sahara and New England come next for reasons already given, in addition to the significant amount of energy absorbed by the atmosphere even to reach the Sahara.
- Q: What do I need to use this as a battery charger
- I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
- Q: I have seen DIY software which explains everything for novices. Specifically, how to build your own solar panels and tie them into your home electrical system for about $00 in parts.Has anyone tried doing this? Was it easy?
- Your location could effect this answer significantly.If you are in an area that requires considerable amounts of heating,and you are looking to save some money with a homemade project,try solar-thermal.S-T is easy and cheap ,can be built from common scrapyard materials,and will give you a great knowledge gateway . The orientation and tracking skills you will learn can be used later with PVs if you choose,or you can make better concentrators for the solar-thermal and build yourself a sterling or rankin cycle engine to generate electricity.If u need heat,or even hot water, u can start saving the money u put into the system immediately. Concentrated PV is here and now ,but, in a year or 2 it will be cheap and readily available and thats when PV will start to approach the efficiency of solar-thermal.there a great sites and groups on just S-T out there ,join 'em,check 'em out,read the free info from those who have built working systems,and you will probably find a more useful method of saving money and the planet at the same time.Just remember to approach it as a hobby/learning experience at first.Start with solar-thermal....theres a reason the anti-greenies point at the ROIs on PVs,great arguement against alt energy,but over the last 30 years I've shut up quite a few skeptics with my solar-thermal projects ,esp. when coupled with geothermal...have fun,make a local scrapyard owner/worker ur freind..................GEOD
- Q: Can solar panels be used to power a university?
- Yes, solar panels can be used to power a university. Solar energy is a renewable and clean source of power, making it an ideal solution for large institutions like universities. By installing solar panels on rooftops, parking lots, or open spaces, universities can generate a significant amount of electricity to meet their energy needs. Additionally, universities often have large campuses with ample space for solar panel installations, making it feasible to generate a substantial amount of solar power.
- Q: Can solar panels be used in conjunction with a backup generator?
- Yes, solar panels can be used in conjunction with a backup generator. This setup, known as a hybrid system, allows the solar panels to generate electricity during the day and excess power can be stored in batteries or fed back into the grid. When there is insufficient sunlight or high energy demand, the backup generator can kick in to provide electricity. This combination ensures a continuous power supply, making it a reliable and sustainable solution.
- Q: Can solar panels be installed on a theme park or amusement park?
- Yes, solar panels can be installed on a theme park or amusement park. In fact, many theme parks around the world have already installed solar panels to generate clean and renewable energy. This not only helps to reduce their carbon footprint and dependence on fossil fuels but also saves them money on electricity bills in the long run. Additionally, solar panels can be integrated into the design of the park, complementing its aesthetic appeal and showcasing the park's commitment to sustainability.
- Q: Can solar panels be installed in a shaded area?
- Solar panels can still be installed in a shaded area, but their efficiency and electricity production will be significantly reduced.
- Q: Im doing a science project and I need to know what gases or liquids a solar panel can make that is not friendly to the environment. Please name all the gases and liquids and explain how they damage the environment. It would be most likely that you will get best answer if you find all the bad things about solar energy and explain why they are bad and how they affect nature. that would be helpful to. Thank you
- i think that there should not be gases produced from solar panel,that we use.
