Q: Can I fet free solar panels. This site okorder sells a book that tells how to, but I ordered tha book more then a year a go, and in never came. I even sent them a email a day for more then 3 months and never heard back from them. If anyone knows how to get free pannels, please let me know how. A $300.00 a month bill is slowly killing me.
If you sent payment via the US mail, report them for fraud. Next, solar panels usually have a high upfront cost for the homeowner - but this is usually offset by a tax refund. The amount of refund varies by area. Check out the cost with a local installer - they have the most motivation to know all the tax breaks you can get. Then save for it, and in the mean time switch your bulbs to fluorescents, unplug your coffee pot, computer, VCR, microwave when off, and see if your energy company provides free insulation evaluation services. And reduce your temperature this winter by 2 degrees, and change that furnace filter.
Q: What is the average cost of solar panel installation?
The average cost of solar panel installation can vary depending on various factors such as the size of the system, location, type of panels, and any additional equipment or services required. However, as of 2021, the average cost in the United States ranges from $15,000 to $25,000. It is important to note that there may be additional incentives, tax credits, and financing options available that can help reduce the overall cost.
Q: I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?
How long is the run? 2 gauge is a good choice for runs up to 25 feet at 20 watts, if you are much further in your run, move to 0 gauge to reduce resistance of the wire itself in the circuit. Otherwise refer to the prevailing electrical code of your local unit government. This is a must if you plan to maintain insurance. At lower voltage, a little resistance means a lot. 4 gauge might be okay for 20 VAC, but the voltage drop on a low voltage system from resistance of the wire itself is measurable at 20 feet. It is the difference between a light fixture working or not. If you are planning on adding additional panels in the future, you can get terminal buss with screw hold downs at various vendors like Mouser or Digi key. Each panel can be on it's own screw, while the buss is common on the other side of the connection. one for the positive and one for the negative.
Q: How do solar panels affect the overall energy consumption of a building?
Solar panels can significantly reduce the overall energy consumption of a building. By harnessing the sun's energy and converting it into electricity, solar panels provide a clean and renewable source of power. This reduces the reliance on traditional fossil fuel-based electricity, leading to lower energy bills and a reduced carbon footprint. Additionally, excess energy generated by the solar panels can be stored or fed back into the grid, further offsetting the building's energy consumption.
Q: Can solar panels be installed on churches or religious institutions?
Yes, solar panels can be installed on churches or religious institutions. In fact, many religious institutions have embraced solar energy as a way to reduce their carbon footprint and promote environmental sustainability. Installing solar panels on churches not only helps them save on energy costs but also serves as a symbol of their commitment to caring for the planet and being good stewards of the environment.
Q: What is the efficiency of solar panels?
The efficiency of solar panels refers to the amount of sunlight that is converted into usable electricity. It is typically measured as a percentage and can vary depending on factors such as the quality of the panels and the location of installation. On average, modern solar panels have an efficiency range of 15% to 20%, with some advanced models reaching up to 25%.
Q: I would like to know how do you build a solar panel?
i think the evil Genius book has how to build home made solar cells.
Q: I've been thinking and I'd like to have solar panels installed on my roof at some point to help reduce our electricity consumption- but I live in IL and in the winter it frequently snows. Is there such a thing as heated solar panels so they don't get coated w/ice or snow? Are solar panels even a feasible option in IL? Thank you, Anna
You can do solar anywhere and yes, they're a viable option in IL - as they are where I live - in Maine! We get snow and also lots of low light days in the winter. It's not as easy as say -having solar in New Mexico (self-identified as the solar capitol!) but - you can still generate a nice amount of electricity with your solar panels on a nice day in IL - and they're fine in the snow.
Q: Can solar panels be used to power a museum?
Yes, solar panels can certainly be used to power a museum. Solar panels are a reliable and sustainable source of energy that can generate electricity to meet the power requirements of a museum. By harnessing solar energy, museums can reduce their carbon footprint, lower energy costs, and promote environmental sustainability.
Q: Can solar panels be installed on a school or university campus?
Yes, solar panels can be installed on a school or university campus. Many educational institutions are adopting solar energy as a sustainable and cost-effective solution for their energy needs. Installing solar panels not only reduces greenhouse gas emissions but also provides educational opportunities for students to learn about renewable energy. Additionally, it can save the institution money on electricity bills and potentially generate revenue through excess energy production.
