- Q: can anyone help me? i was thinking of installing solar panels to cut bills but would it be a waste considering its gonna need a circulating pump running almost 24/7 (which will use electricity) and even still will only provide me with quot;warmwater? also would it be possible to install the solar panels for the sole purpose of providing sufficient power to run electric heaters instead of using gas/oil? this way allowing me to have a warm house without the expensive bills. brobably talking about running 7 heaters/electric radiators.
- A thermal solar panel to feed your water heater is the most efficient. But you need a classic heater system too when there is no or little sun. Solar panels to heat a home is not at all recommended. First of all, you get less day light and less sun in winter, so you won't get much electricity. They work best in summer, but electric panels have poor yields and are a very long term investment. You will need to wait years before saving money. Natural gas, a well isolated home, and a good old sweater is the best way to cut bills.
- Q: I have a 500 watt inverter and battery but need solar panels to run my need. I want to have enough juice to run a computer and monitor and sometimes a 5w amp. I am not sure how much power is needed to run the computer (standard desktop with 5flat screen with an additional surround sound system) though on the side of the computer it says 5 amp but I know I used to run it and monitor and surround sound with a heating blanket on the same circuit which was rated at 20 amps. My question is that I would like to go and buy some panels (cheaply as I'm unemployed) from somewhere like Harbor Freight that would meet the need of the converter to supply enough amperage. So what size panel(s) or panels would I need to run this setup? If I am correct I think 500 watts is equal to 5 amps. Would this even work? Could I run a partial system where I could run some of the stuff to take a load off? I need to lower my electric bill somehow. Thanks!
- Solar okorder in their survival discussion in the archive, this exact project was discussed at length.
- Q: How do solar panels impact the electrical grid?
- Solar panels impact the electrical grid by generating clean and renewable energy from sunlight. When connected to the grid, they can feed excess electricity back into the system, reducing the overall demand for fossil fuel-based power generation. This helps to lower greenhouse gas emissions and dependence on traditional power sources. However, the intermittent nature of solar power requires careful grid management and integration to ensure stability and reliability.
- Q: How do solar panels affect the value of a home?
- Solar panels can significantly increase the value of a home. They offer long-term cost savings on electricity bills and can generate additional income through net metering or selling excess energy back to the grid. Additionally, solar panels are environmentally friendly, which appeals to many buyers and can make a property more attractive in the market.
- Q: I bought a pack of OEM mini solar panels that produce 4.2v and 22mA and I was just wondering how many LED's I could hook up to one mini solar panel? I currently have one green LED with a resistor on the one panel but was wondering how many I could possibly run off of one panel?
- You need to answer that by designing circuits to provide each LED with its specific voltage and current requirements, and then see how many you can supply.
- Q: Hoping to find instruction, materials list and hardware needed to construct solar panels myself, how many and make it happen instead of talking about it
- If you think that a solar storm is going to knock out most power utilities in that time, what makes you think that your solar panels will not be affected as well? The cost to even come close to light up half your house will be prohibitive and will take at least a decade or 2 to just break even on your original costs. May want to do a little more research on your 202 storms. If you are concerned about the power going out for a while, then you better check at what else may happen.
- Q: What is the working principle of solar panels?
- Based on the above considerations, silicon is the most ideal solar cell materials, which is the main reason for solar cells to silicon-based. But with the continuous development of new materials and related technology development, to other village-based solar cells are increasingly showing attractive prospects.
- Q: How do solar panels affect roof weight load?
- Solar panels can increase the weight load on a roof, but their impact is generally minimal. The weight of solar panels is usually evenly distributed across the roof surface, and most roofs are designed to handle this additional load without any issues. However, it is recommended to consult with a professional to assess the roof's structural integrity and ensure it can support the added weight of solar panels.
- Q: I got an 8v solar panel for a project today, the only problem is that it came without any wires attached to it. Now i don't know what type of wires i should use and if i should solder them on or if i should use epoxy instead. Can anybody help me out?
- Most epoxy is not very conductive. I would go with solder.
