Guys this is my final yr project , i am planning to use solar panels on the roof of the tuk-tuk, to power it up.Please help me as to how to go about this and what would be the approximate cost..please give any refrences or websites that might help..please help me out on this one..ill be very grateful ,thank you

A tuk tuk has an engine with a capacity of about 175-400 cc, about 15-30 horsepower or 11-23 kW. At a ballpark value of 70 mW per square inch of solar panel – obtained from

My husband I bought our first home last year and this summer has been brutal! We’ve got fans upstairs in the all the rooms but it’s still so hot upstairs. We want to get an attic fan installed, a solar one preferably. We rarely use our air, but it would help tremendously on those really hot days and I know it’s also good for winter to keep moisture down.
We have a tile roof and I wonder if that would make installation harder, especially since the tiles break easily. Anyone install something like this in their home? Was it worth it? Was it more expensive because of the tiles?
Thankfully we are lucky enough to have a couple of trees out front and have a relatively low electricity bill, but it could always be better and I would love to not have to use the air at all!
No, our fans are not useless, they help the room feel cooler and they use much less energy than air conditioning. That is widely known.

I don’t know of anyone that has a solar powered attic fan. But I know of people having solar on their homes and run an attic fan.

i live in sunny southern california and i heard that installing solar panels on your roof can fully power your home on a summer day! is this true? how much would it cost on average? my home is a two story home in the suburbs, lol what are the pros and cons of doing this?

No they are not worth it.I had some installed just to run my pool and I would have to live to be 200 years old to break even.

does anyone know why you can buy solar lights with built in solar panel and others come with large seperate solar panel with wire?does it mean the ones with seperate solar panel will be more powerful i.e brighter?

They may be more powerful, but it could just be the design, or a lower cost modification that a manufacturer has made, from a mains powered type, to make it run off solar.

electricity to get the car going.and the tire rotating to cause friction like a windmill to recharge the battery like a altenator on a car. not to run the car be keep but the battery charged
and solar power to help maintain balance of power

Well, we do have hybrid vehicles that use regeneration to get back some of the otherwised wasted energy when breaking. But please..do not get into th eperpetual motion thing . Any energy regenerated must be generated first by gasoline or electricity, which ultimately is supplied by fossil fuel. Dont get the impression that if you start a car moving with an electric motor and battery, and even mount a winmill device that spins as the car moves, trying to charge the battery…it wont work! If you put a windmill, or propeller device on a vehicle, and turn a generator trying to recharge the battery you are using to move the vehicle in the first place..you are wrong. Whatever energy you would be able to produce with the windmill attachment, would be used up by the battery due to the extra force needed to push teh vehicle forward and turn that winmill/generator. You would end up with a net loss of energy, not a gain, and actually discharge the cars battery faster!
