Q: My house is aligned exactly North-South, so I have no roof facing South. Is it worth installing solar panels? Are there any good options for dealing with this situation?
In your case you will need twice as many panels. This is because the panels on the west side of the roof will be in shade in the morning and the panels on the east side of the roof will be in shade in the afternoon, and a solar panel in the shade makes no power, or at least very little power. So right there you doubled the cost of an already too expensive system. Or you could build special stands to hold the panels facing south. It would be cheaper to just move to a house with better alignment!
Q: K i'm almost ready to give up! I've bought every kind of pv I can think of, and I can see this technology will not be affordable in my lifetime.I conserve all I can (so far as to handwashing my laundry etc) I'm not rich, but I'm saving for a solar pv with decent amperage. I love tinkering with things if I see the point.All the cells i've seen are very weak. What PV would you buy? (all I need is to power my computer from a deep cycle 2 volt battery connected to an inverter)God Bless You
If powering a PC is your only goal, consider replacing the power supply in your PC with one that runs off native 2 volts (like the kind intended for RV's). Then you can avoid the 30% loss of energy in a cheap inverter.
Q: How do solar panels affect the electrical grid?
Solar panels can have both positive and negative effects on the electrical grid. On the positive side, solar panels generate clean and renewable energy, which reduces the reliance on fossil fuels and decreases greenhouse gas emissions. Additionally, solar panels can help decentralize the grid by allowing individual households or buildings to generate their own electricity, reducing strain on the overall grid. However, the intermittent nature of solar power can pose challenges for grid operators, as it requires careful management to balance supply and demand. Moreover, the increased number of solar installations can also lead to voltage fluctuations and grid instability if not properly managed. Overall, while solar panels offer numerous benefits, their integration into the electrical grid requires careful planning and coordination.
Q: I was wondering if they create other forms of energy besides electrical that is unwanted. Like heat due to the friction of something, or sound. Also why is a solar panel not able to collect 00% of the energy that is striking its panels. And how could the efficiency of this be hypothetically improved.
Science. The best solar panels we have only get like 22% of the sunlight for conversion into energy. That is simply the best they know how to make with current technology. And for that your talking about a mobile panel that tracks the sun as it moves at the equator. A solar panel in say Canada is lucky to get 0% even on a sunny day. But even if a solar panel got 00% efficiency, it's still not a lot. Sunlight is too diffuse to be a good power source, and you'd need to cover lots of ground to get power. Worse, you can only get power when the sun is out during the day. So for power at night you'd need a battery, or another source of power. The 'newest' idea is to capture sunlight to make 'lasers' that boil water, to turn turbines and make electricity. They cost way more then they are worth right now though...
Q: Can solar panels be used for powering outdoor lighting?
Yes, solar panels can be used to power outdoor lighting. Solar panels convert sunlight into electricity, which can be stored in batteries and used to power outdoor lights during nighttime. This allows for cost-effective and environmentally friendly outdoor lighting solutions.
Q: Can solar panels generate electricity at night?
No, solar panels cannot generate electricity at night because they rely on sunlight to produce energy.
Q: Can solar panels be used to power an entire office building?
Yes, solar panels can be used to power an entire office building. By installing a sufficient number of solar panels on the roof or surrounding areas, an office building can generate enough electricity to meet its energy needs. Additionally, by integrating battery storage systems, excess solar energy can be stored and used during non-sunlight hours, ensuring continuous power supply.
Q: Currently being sold today! I know SunPower corp. commercial panels are about 20%.
About 20-22 percent is about right for panels affordable by most consumers. Even then, you still only get enough power to light a couple of lights for $400-$500, and only works when the sun is shining.
Q: Can solar panels be installed on data centers or IT facilities?
Yes, solar panels can be installed on data centers or IT facilities. In fact, many data centers and IT facilities are increasingly adopting solar energy as a sustainable and cost-effective power source. Solar panels can be installed on rooftops or in open areas surrounding the facility to generate clean electricity and reduce their reliance on traditional grid power.
Q: I live in Hawaii and having a solar panel is not a bad idea since we have plenty of sun the only problem is that it cost a lot of money and takes many years before you get your money back. There are kits available where you can make and install your own solar panel and wind turbine but is it bull **** or is it a good deal?
How confusing is this to do? Judging out of your question and rationalization which you posses no information or historic past in this section: Very confusing. Is it useful? no longer even remotely useful. high priced? confident, you will no longer stay long sufficient to make certain a ROI = return on your investment. Will I keep funds or lose funds? you will lose funds, equipped perfect the fee per Kilowatt will a techniques exceed what the electrical powered employer grants for you. If it replaced into elementary, useful, much less high priced and would keep funds you’d see those going up in all places. i understand a great form of very gifted human beings in this section ( consisting of me ) that could try this in a minute if ~ ~ it replaced into elementary, useful and would keep funds. If it’s a undertaking which you’d in simple terms choose to play with, decide for it. yet once you think of you’re going to keep funds, forget approximately it.
