Q:I am looking to wire in some solar panels into my home. I already have plenty of wiring, and some solar panels around. I just need to know what I need to do to wire them into my home so I can lower my electric bill. This past month it was six hundred dollars.Can someone direct me to some information, or tell me how without telling me to hire some guy to come out to charge me thirty thousand dollars to install two or three thousand dollars worth of equipment?
I am all for do-it yourselfers, I am one, but... Sorry to tell you, but connecting solar panels to grid power will require an electrician. There are many requirements for special disconnects to prevent harm to the utillity company workers that must be considered. You will also have to have an inverter sized to match your panels. The simple answer is to connect your panels to something specific, without connecting it into your house wiring. An example is to connect your water well pump to solar power and disconnect it from the grid. But you will still need an inverter and will need to calculate the power demands of the pump and the amount of power available from your panels, which varies by your longitude and latitude. It sound like a simple thing to do, but without special training and experience you will be sorry if you try this yourself.
Q:Where can I find updated info about solar panels for home?
Of the practical technologies, crystalline silicon is still king. There have been improvements in manufacturing efficiency and price, but the fundamental technology is unchanged. For the past couple decades, there have been startups claiming that they will have a breakthrough available in 2 years, but so far, nothing has beat crystalline silicon for general applications. The appeal of thin-film was its cost, at the penalty of efficiency, but when the prices of crystalline plummeted, the cost argument went away. That wasn't the only problem Solyndra had, but it contributed to the company's demise. Organic solar cells show promise, and might ultimately be very cheap to manufacture, as they don't involve the high-temperature processing that semiconductors do. The main problem today is that they're not stable at the temperature of a hot roof. But then again, a few years ago, organic LEDs were the same way, and now they're commonplace in big TV's. Only time will tell. From a homeowner's standpoint, the install is routine, but still best done by professionals. It's like putting a new roof on a house, or wiring in central air conditioning. For most, it's better to call a pro.
Q:Does any one know how to make a solar panel or a type of Alternative energy maker. Best answer gets 0 points
Though wind energy is the big thing at present, and I derive a significant part of my income from doing engineering on these wind farms, I personally prefer a wood-fired boiler steam turbine generator combination as the best renewable energy system. Wind generation works great when the wind blows, but if you intend to go off-grid expect to invest in energy storage and some other form of backup power. Solar photovoltaic panels are about 6% efficient at best, and that's only when the sun is shining brightly. If you consider that trees (biomass) are a completely natural, renewable energy resource, and couple this energy resource with modern clean combustion technology, this makes for a great dispatchable, long-term sustainable, ready-when-you-need-it solution. Go wood!
Q:What happens to solar panels during extreme weather conditions?
During extreme weather conditions, such as hurricanes or hailstorms, solar panels can be damaged. Strong winds can cause them to be torn off or destroyed, while hail can crack or break the glass surface of the panels. Additionally, heavy snowfall can cover the panels, reducing their ability to generate electricity. However, most solar panels are designed to withstand various weather conditions, and manufacturers often perform rigorous testing to ensure their durability and resistance.
Q:I am looking at building my own solar panels to at least help cut down the rising energy bill. I know its expensive. I already have the solar cells so no need to worry about listing that. But i am looking at wiring it directly into the house. Is there any parts that you could list for me, that would be great. thanks
Most okorder / . If you had an array of 0 or more panels, it would usually be cheaper to get a single, large inverter. The usual path taken with homemade panels seems to be using them to charge a battery, then running things of the battery. And it's usually a fun thing to do, but not a way to save money. Just so you know.
Q:How do solar panels affect the overall resilience of a building?
Solar panels can significantly enhance the overall resilience of a building. By generating clean and renewable energy, they reduce dependence on traditional power grids, making the building less vulnerable to power outages or disruptions. Additionally, solar panels can provide a reliable source of electricity during emergencies, ensuring critical systems like lighting or communication remain operational. The energy independence offered by solar panels enhances the building's ability to withstand and recover from various crises, ultimately improving its overall resilience.
Q:Can solar panels be damaged by hail or extreme weather?
Yes, solar panels can be damaged by hail or extreme weather. Hail stones can cause cracks or dents in the panels, compromising their efficiency and potentially leading to water leakage. Additionally, extreme weather conditions such as hurricanes or strong winds can dislodge or break the panels, causing significant damage. It is important to consider the durability and quality of solar panels when installing them in areas prone to such weather events.
Q:How do solar panels impact the environment?
Solar panels have a positive impact on the environment as they generate clean and renewable energy without emitting greenhouse gases or other pollutants. They help reduce our reliance on fossil fuels, decrease air pollution, and mitigate climate change by curbing carbon emissions. Additionally, solar panels require minimal water usage compared to other energy sources and have a long lifespan, making them an environmentally sustainable solution for electricity generation.
Q:Are solar panels suitable for all climates?
Solar panels can be suitable for a wide range of climates, but their efficiency may vary depending on factors such as sunlight intensity, temperature, and cloud cover. While solar panels can still generate electricity in cloudy or cold climates, they tend to perform best in regions with abundant sunlight. Advances in technology have made solar panels more adaptable and efficient in various conditions, making them a viable option for many different climates.
Q:Can solar panels be used to power a zoo?
Yes, solar panels can be used to power a zoo. Solar energy can be harnessed through panels to generate electricity that can power various facilities within a zoo, including enclosures, buildings, and even some of the exhibits. This sustainable energy source can help reduce the zoo's carbon footprint and reliance on traditional power grids.
