- Q: How will i construct solar panel?
- The key is like a spiral stair case with landings at each floor, but the momentum of having to turn is enough to climb from floor to floor. I guess the energetics use the handrail quite utterly and only, pressing against it like bearings in a wheel. With metals and metalloids a 3' x 3' solar panel would power your house and car and make your energy bill negative, but costs several million dollars since the chain of rare elements is only affordable to obtain by strip-mining top soil of many square miles of fertile land just for a single panel and thus destroys good farmland for hundreds if not thousands of years. Clearly solar panels will not solve any problems ever...unless their yours only.
- Q: Can solar panels be installed on a barn or agricultural building?
- Yes, solar panels can be installed on a barn or agricultural building. In fact, these structures often provide ideal conditions for solar panel installation due to their large, unobstructed roofs and proximity to open spaces that receive ample sunlight. Installing solar panels on barns or agricultural buildings can help farmers and landowners generate renewable energy, reduce electricity costs, and contribute to a more sustainable future.
- Q: Solar panel packages have different levels of power. For instance you can get a kw system but is this kw per hour or day. How does this work?
- it would be an instantaneous rating at maximum output. To get the the amount of power produced, you would multiply the number of hours at near peak output. kw X 5 hours = 5kwh or about 50 cents of electricity.
- Q: Alright my family and i are buying a new home in Bradford,Ontario, we we thinking about solar panels and had a couple questions:. how much are they each?2. how many will we need to power a single family home(4 ppl)3. where can we find them in ontario?4.how much money do they really save you?5.what kind of energy do they providfe you withand other basic info or a website i can check out would be great!thanks in advance!
- Just think about it and don't do it unless Ontario and the Utility companies give a huge rebate. Forget tax credits. Solar voltaic panels generate electricity...it will take more than 20 years to break even...assuming they last that long. Solar panels that generate hot water may be OK but will take about 0 years for a payback.
- Q: How do I choose the right size of solar panels for my home?
- To choose the right size of solar panels for your home, you should consider factors such as your average electricity consumption, available roof space, and budget. Start by analyzing your energy usage over the past year to determine your average daily kilowatt-hour (kWh) consumption. Next, calculate the solar panel system size needed by dividing your average daily consumption by the average daily sunlight hours in your area. Additionally, assess your roof's orientation, shading, and structural capacity to determine the maximum number of panels it can accommodate. Finally, take your budget into account and consult with a professional solar installer to help you determine the appropriate size and type of solar panels that best meet your energy needs.
- Q: Can solar panels be installed on a car?
- Yes, solar panels can be installed on a car. Solar-powered cars have been developed and are being used as a means of reducing carbon emissions and increasing energy efficiency. These panels are typically mounted on the roof or hood of the car to collect sunlight and convert it into electricity to power the vehicle's functions. However, the amount of energy generated by these panels may be limited, and they are usually used as a supplemental power source rather than the sole means of propulsion.
- Q: I am planning to run a couple of dc motors on solar current. I have a couple of 450mA 4V, 200mA .5V, 00mA 9V solar panels with me. I need to run a pair of .5A 9V motors. Suggest me a circuit along with other equipments I might require. For your info, I am trying to build a solar powered drone / UAV
- I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
- 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: Interested in buying solar panels to save on electric bill.Any government help plans?
- I don't believe that there is any help yet.
- Q: What is the most efficient solar panel, how many would we need to power the United States, and how much land would it take?
- 50 billion panels million acres nukes are better. MIKE
