thanks you sir
please give me your contact detail

When you say "make" a solar panel at home, I assume you don’t mean installing one–correct?

So, that means you’re going to collect a bunch of photovoltaic cells and connect them into a solar array–right?

I hate to be the bearer of bad news, but unless you have electronics experience in the area of power conversion and optoelectronics, I suggest you abandon the idea. Here’s why.

First, if you’re using photovoltaic cells, each one is probably on a glass substrate. The cell needs to be shock mounted so any impact will not fracture the glass substrate.

If for example my home is 4 bedrooms and and my roof face south with the angle of 40degree.
And house is located in Great Manchester area.

Which photovoltaic system is best for you depends on your needs. The only limitation would be how many panels you can fit on to your roof. If your roof can fit 4kW photovoltaic great news. Different panels have different Wattage which means you can end up having from 8 panels up to as many as your roof would allow up to 4kW system. Of course you could install larger system but 4kW give you best return on your investment. Everything larger then a 4kW will have a lower tariff, which means the government won’t pay as much for the harvested electricity.

I wanted to know the costs of Solar panel in India for a 2 bedroom house..is it on monthly basis , or one-time investment, maintenance costs…and if it costs more than our regular power supply provided by the government.

It really depends on how big the roof is ? and How many panels you want to install? the price is normally counted by the amount of electricity it produces (per kw). My guess is for a 2 bedroom house it will cost around 8 to 9 lakh rupees which you will have to pay yourself for the installation and it pays you back by saving your energy bill.

I am thinking about something called, I think, "thin layer solar panels". Also would like info on any federal monetary help on paying to convert to all solar power in the home.

Thin film solar sheets are a relatively new technology compared to standard glass plated PV panels. Standard panels have been around much longer and they are more efficient, meaning you would need more roof space with thin film than with regular.

I just bought a 100Watt PV panel and was curious how this is done. I don’t want it flying off the roof when I’m going 75MPH down the freeway. I also don’t want to pay $100 for a few pieces of aluminum. Some of those mount prices are highway robbery! Am I supposed to put a board under the panel for strength? They seem very fragile. I’d appreciate your help. Thanks for reading.

If you just want to mount it flat on the roof (with a little gap under it for airflow), use the Unirac RV mounting feet for $20. http://www.altestore.com/store/Solar-Panel-Mounts-Trackers/RV-Specialty-Solar-Panel-Mounting/Unirac-990009-RV-Mounting-Feet-Set-4-U-MF-4/p3931/

I’m interested in installing myself but have no knowledge of solar panels.Can the excess be sold back to the national grid and how does that work?. What is the average cost?. Where is the best place to get all the equipment from?. Does anyone sell kits for individuals with everything needed included.? What can be run off an average size panel. What is the best size panel to start with?.

They don’t really produce enough electricity to sell to the National grid. I assume you’re in the UK. A better bet is panels that heat water using the heat of the sun. In winter the water coming off the mains is close to freezing, warm it up before it goes in to your hot water tank and that will save energy and much cheaper than solar panels that produce electricity. I assume you are turning your computer off when not needed. Turning your TV off instead of leaving it on standby. Using low energy light bulbs. Wearing warm clothing in winter and turning the heating down a little. Driving only when you have to? Saving energy is usually better than producing it. I’m quite interested in these new "bright" LEDs – they are really efficient at producing light. I find "low energy" light bulbs are useless for many applications. Like I can’t see to read! Leds may replace them soon. I had LEDs for my Christmas lights and they were efficient and controllable.

also what would the pro vs cons be?
by levels i mean floors. and this is all for a standard urban house. im not looking for something ginormous that will break any municipal codes.

First off you need to find out if wind turbines or solar panels are even allowed in your location.

Wind turbines generally need to be located at least 15 ft. higher than any trees or rooftops in the general area (higher than that is even better). The tower must also be located so that if it falls over it can not hit your own home or cross a neighbors property line. You also need to be located where there is sufficient wind available to justify the installation of the equipment.

i have been looking for how to make solar panels at home for cheap. i only found expensive ebooks that tell you what to buy and how to put it together. is there anything free someone posted somewhere on what to buy and how to put together solar panels cheap? if not then windmills work too, so long as i dont have to buy an ebook or anything like that. maybe someone posted how to make one in a blog somewhere. if you know where, please tell me the link. thanks!

My dad made a solar heater the following way, maybe you can modify it for your needs?

I don’t know anything about where to buy solar panels. I just want to save on the electric bills.
Thank you all for providing good answers. I’m not particularly good with math and engineering. But do you guys think that solar panels could power an airconditioning unit? As far as I know, these consume way too much electricity

Simple answer.

Anything you can power with your normal household electric can be powered by solar.

So you know what a solar panel is:

A "solar panel" is more then one solar module mounted on a frame to be installed as a single unit into a solar array.
