- 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.
- With your load, the largest system on the page I reference above would not power your entire house, if all the AC units are running. However, how often does that really happen? You need to look at your utility bill and find your actual amoutn of KW hours of electricity used in a year and you hav enot told us that. The base price of top system quoted here without incentives is over $70,000. As you can see, the lions share of incentives is the utility company followed by federal. I have no idea if your local utility company offers incentives or not. You would have to resolve that with them. However, the federal incentives are still there even if your state and local utility has none. However, the price to you goes way up without all of these incentives. And your idea of using windows to mount solar cells is totally impractical. Yes, I know there are web sites that advertize just that, but it is total BS. The first word of advice to anyone looking to do this sort of thing is to FIRST have a complete energy audit done and then do whatever they say to conserve as much energy as possible, thereby reducing your need for solar power. Only then should you look at using solar to cover part of your load. We are a foster family and have adopted 5 children< WOW! I would like to thank you for what you do.
- Q: How do solar panels affect the local job market?
- Solar panels can have a positive impact on the local job market by creating new employment opportunities. The installation, maintenance, and manufacturing of solar panels require skilled workers, thus leading to job growth in these sectors. Additionally, the shift towards renewable energy sources like solar power can stimulate the local economy through increased investments and business development.
- Q: Can solar panels be used for charging electric bikes?
- Yes, solar panels can be used to charge electric bikes. By converting sunlight into electricity, solar panels can provide a clean and renewable source of power for charging the batteries of electric bikes. This allows for sustainable and eco-friendly transportation options.
- Q: Can solar panels be installed on an agricultural greenhouse or nursery?
- Yes, solar panels can be installed on an agricultural greenhouse or nursery. In fact, it is a growing trend to incorporate renewable energy sources like solar panels in agricultural operations. Solar panels can provide a sustainable and cost-effective solution for powering greenhouse operations, reducing energy costs, and minimizing environmental impact. Additionally, the open space on greenhouse roofs or nearby land can be utilized for solar panel installations, making it an ideal option for farmers and nursery owners looking to adopt clean energy practices.
- Q: in the afternoon sun heat increases to high level due to which the panels heats up very high now my question is this heat will effect the panels life time and will damage the panels or not ??
- They degrade over time, losing efficiency. They're generally good for several decades.
- Q: Can solar panels be installed on a carport?
- Yes, solar panels can be installed on a carport. In fact, carports are an ideal location for solar panel installation as they provide ample space, unobstructed sunlight, and can also serve as a shade provider for parked cars.
- Q: Do solar panels work with any type of heat or only sunlight? I have a bunch of little ideas floating around in my head and Id like to get them on paper but only if they really would work.Also does a concentrated amount of heat on one solar panel piece (quot;xor so) produce a higher or equal amount of electricity than a less concentration over a larger area?
- Last year here in the UK we had in my area snow most days quite heavy lays of it I noticed after clearing my solar cell panels in daylight conditions without any sun they were producing a fairly good voltage/amp ration, also as daft as it sounds in the middle of a January night with a good moon shin the snow refection produced a good electricity supply!. absolutely true.
- Q: Is it good? ( solar energy)
- It depends mainly on where you live - both politically and geographically. It's very worthwhile if you live in the Southern hemisphere and your house faces north. The same holds true if you live in the Northern hemisphere in a south-facing dwelling. If your government gives a generous rebate towards your purchase of the panels (as the Australian one does) then ,yes, it is worthwhile as you can make your money back in only a few years. Of course if your motivation is more an ecologic than economic one then go ahead and do it.
- Q: Can solar panels be used for powering a hospital or healthcare facility?
- Yes, solar panels can be used for powering a hospital or healthcare facility. Solar energy can be harnessed through photovoltaic panels to generate electricity, which can be used to meet the power demands of various medical equipment, lighting, heating, and cooling systems in hospitals and healthcare facilities. This not only helps reduce reliance on traditional energy sources but also provides a sustainable and eco-friendly solution for powering critical medical infrastructure.
- Q: Can solar panels be used for powering a hotel or hospitality establishment?
- Yes, solar panels can definitely be used to power a hotel or hospitality establishment. Solar energy is a renewable and sustainable source of power that can be harnessed through solar panels to generate electricity. By installing solar panels on the hotel's roof or in nearby areas, the establishment can significantly reduce its reliance on traditional energy sources and lower its carbon footprint. Solar power can provide a consistent and reliable source of electricity, which is crucial for powering the various amenities and facilities within a hotel or hospitality establishment.
