Q:Are there any disadvantages to using solar panels?

Yes, there are a few disadvantages to using solar panels. Firstly, the initial installation cost can be relatively high, making it a less affordable option for some individuals or businesses. Additionally, solar energy production relies on sunlight, which means that solar panels are less effective during cloudy or rainy days, or at night. This intermittency requires a backup energy source or energy storage system, adding to the overall cost. Moreover, solar panels require a significant amount of space for installation, which may not be feasible in densely populated areas. Lastly, the manufacturing process of solar panels can have environmental impacts, as it involves the use of certain materials and chemicals. However, it is worth noting that continuous advancements in technology are reducing these disadvantages, making solar panels an increasingly viable and sustainable energy solution.

Q:How can I calculate the amount of watts needed for a solar panel to power a water and air pump in gal/hr and a 600 watt LED light?

Mimi: Solar Power is not really that economical, and has many other disadvantages as well. You did not specify much info in your question as to the size of the water or air pump. So let's make some assumptions to get you some numbers. ) Let's say the water and air pump are about HorsePower (HP). The HP pump , considering efficiency losses, will draw around ,000 Watts , or kW. 2) The 600 Watt LED Light is quite high --- they are usually much smaller lights 40 Watts or less. BTW --- these LED lights are very expensive light as well. Just so you are aware. Between the pump(s) ( maybe 000 to 400 Watts) and the 600 Watt light ----- and without knowing the specifics --- you are probably looking at around 2,000 Watts or 2 kW. A 2 kW Solar PV unit will run around $20,000. The PV unit will only run at full capacity during daylight hours. They usually average about 5 hours per day. So you will only be able to run your pump and LED Lights during the middle of the day --- maybe 0:00 AM to 5:00 PM. If you want to run the pump and lights after sundown, you will need battery back-up. The electric storage batteries will likely run about an extra $5,000. They will last about 5 years. If you decide this doesn't work out well --- you can stay with the local utility --- at $0.0 per kWh. It will cost you about $0.0 per hour to run the pump --- maybe 30 to 50 cents per day. It would cost you about 6 cents per hour to run your light. Maybe 30 or 40 cents per day. You could essentially run your pumps and light several hours each day --- all for about $ per day, or $365 per year. This sounds like a less costly alternative.

Q:What is the proper diode to use on an 5v 500ma solar panel?

At least a 2 amp diode. rated above the 2 volts that are commonly found on the market. A blocking diode must be able to stop a higher current and voltage than the panel maximum. A diode will work on any voltage and current lower than it rating.

Q:I need help?!!

benefit- It makes use of the Suns organic engery to produce potential for a house/employer which saves money as against employing potential from the community materials for electricity. it will keep away from lots of money in case you reside in an area that is sunny a super style of the year. disadvantage- You extra suitable wish that is sunny for a on an identical time as to construct a inventory pile of potential. It somewhat relies upon on your desires for potential, in case you do no longer use incredibly some it and stay in a sunny section a super style of the year, then you incredibly could desire to have a super style of potential that only kinda sits there. yet once you reside in an area it somewhat is frequently cloudy all year around then image voltaic panels does no longer be superb for you.

Q:Dont/Cant work alone?when you buya asolar panel you mUST GET bATTERIES, voltage regulators and many else stuff?cant they just work directly? or can i use normal batteres like Car batteries?The one who Really knows 0 pts. thanks

It is a system, you can get a small scale panel that can do things like charge cel phones and ipods. The type of system I have installed on my home needs a converter that turns the dc current that is produced by the panels into ac current to run in my home. I don't have a battery system because I'm not off the grid. When I'm generating more electricity than I am using I sell it back to my utility and at night when I'm not gernerating any electricity I buy it back again. Basically my meter runs backwards durning the day and frontwards during the night.

Q:How do solar panels impact the electric bill?

Solar panels can significantly reduce or even eliminate the electric bill for homeowners. By generating clean and sustainable energy from sunlight, solar panels can offset the amount of electricity needed from the grid. Excess energy produced by solar panels can be fed back into the grid, earning credits or monetary compensation through net metering. Ultimately, solar panels can lead to substantial savings on the electric bill over time.

Q:How are solar panels installed?

Solar panels are typically installed on rooftops or open spaces using metal frames or mounting brackets. The process involves anchoring the panels securely, connecting them in a series or parallel configuration, and wiring them to an inverter that converts the DC electricity generated by the panels into usable AC electricity. Additionally, a solar panel installation may require making electrical connections to the building's electrical system and installing a net meter to measure the energy produced and consumed.

Q:Can solar panels be installed on a south-facing wall?

Yes, solar panels can be installed on a south-facing wall. In fact, a south-facing wall is usually the most ideal location for solar panel installation as it receives the maximum amount of sunlight throughout the day, maximizing energy production.

Q:I have a solar panel i got for free and I don't know what to do with it. Its kinda big at about 20x 0and it puts our 2 VOC / .23 ISC. I don't know of anything that I could use it for. Its too big to say charge a phone or ipod....any suggestions??

Solar cells convert the energy of the sun into electricity. By using items commonly found in the home or your local hardware store, you can make a solar panel to demonstrate this photoelectric effect. You can also save energy by converting some of your traditional electrical supply over to solar power. Use sheet metal shears to cut the copper flashing in a square or rectangle to fit the size of the electric burner. Be sure to use a piece of copper flashing that is thoroughly cleaned. You may use sandpaper to thoroughly remove any sign of corrosion before proceeding. Place the copper flashing on the electric burner and turn the burner on. You will need to cook the flashing for as long as 30 minutes or more to develop a thick layer of black cupric oxide.

Q:Hello from SO TX.. I would like to know if anyone out there has SOLAR PANELS on their home?I have a 850 sq ft. house. I called Austin to a company that offers panels and installation. The cost $8,000.00, for 0 panels . The rep said we would save about 2 to 25% on our electric bill /mo. We use approximately 980 kw/mo. Our bill is around $40.00 / mo...I really don't think that's a good enough savings. We figure it would take 25 years to recoup our investment.And where we live in TX it does not offer any incentives. The gov. allows you a $2000.00 tx break.

Be glad you didn't buy. The current products are dinosaurs, 50 year old over priced tech. Don't lose hope though. The thin film tech is just now starting production. It's not yet available to the general public ( production for the next year is already sold out), but will be in the near future as production capacity increases. It should drop prices to about /4 of the current price, and your recoup time will be about 7 years. Go ahead and research thin film solar, and be thankful you didn't buy a product the government has to pay you to buy.
