Q:Are DIY Solar panels legitimate for saving electricity?
Hi Mitch, Yes they are legitimate ans so much so the government will actually help you pay for them. Someone has already mentioned if you purchase them from your local solar panel installer they will not be cheap.They have come down in price a lot over the last couple of years. Yes you can build your own and no its not too difficult.You need to know in your own mind whether you just want to reduce your utility bill or come off the grid completly. The best solution is a combination of wind and solar power and yes you can build your own windmill as well and at the bottom her I will show you where to go to get easy non technical plans. Naturally the sun does not shine at night so your solar panels would not work then but windmills function 24/7 as long as there is wind. If you have nearby neigbours please be aware windmills do make some noise which might upset your neighbours and of course see if you need planning permission from the town. The solar panel plans show you how to set an 80w solar panel which of course would not be able to power your whole house,but once you have built one why not build loads more and each one will get easier to build. Wish you all the best.
Q:Can you tie small-scale solar panel system into household electrical system?
You can't directly connect solar panel into household electrical system,you need to convert DC power to AC power more over it will cost more amount...
Q:Can I plug a solar panel into a wall socket to lower my electric bill?
You're quite right that the solar panel can't be directly connected. I sense that you want to start small, but unfortunately, it's hard enough to make a system with a dozen or more panels pay back. (It can, we have a system...) But with just one panel, maybe a small one, the economy of scale is gone. You need to buy a grid-tie inverter, which watt-for-watt will be more expensive than a regular size one, and for a small panel, the $$/watt value will be poor. There are some [illegal in most places] tiny grid-tie inverters that I see advertised on the web from time to time, with an ordinary plug that goes into the wall. Those are generally against electrical codes, and the danger is real. There is also a crop of micro-inverters being sold by companies such as Enphase. These are legitimate products, but will still be costly per watt, and ultimately, it will be hard to have a net savings over time with just one panel. Have you already taken the conservation steps like LED light bulbs, efficient appliances (especially refrigerator), insulation, and using a power strip to turn off loads that are not being used? That stuff isn't sexy, but saves money fast.
Q:solar panel help needed ?
You need to know how many solar cells are in the panel and what is the rated current each cell will produce. This information should be listed on the panel. Each cell will produce from 0.5 to 0.55 volts DC per cell and each cell will produce a current that is dependent on the size of the cell and the type of material the cell is made from. If the cells are connected in series then the voltage of each cell will add together, that is if you have 30 cells connected in series they should generate about 5 to 6.5 volts DC. If each cell generates .2 amps, then you multiply the voltage of 5 volts DC times .2 amps DC equals 8 watts of power. The current of each cell does not add together when you connect the cells in series only the voltage of each cell. If you connect the 30 cells in parallel then the current of each cell adds together but the voltage of each cell does not. That is 0.5 Volts DC times 36 amps equals 8 watts. The power (watts) produced will be the same. See our blog on the products page to see how to connect solar cells in series and in parallel. We also have a PDF file of solar cells and their rated output current sorted by watts per area and their manufacturer.
Q:Can I use a 250 watt solar panel to power a medium sized upright fridge?
How many watts does your fridge consume? Do you want it to work at night when the solar panels aren't doing anything? Probably not.
Q:I NEED HELP WITH MY SOLAR PANEL SYSTEM PLEASE HELP?
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
Q:Anyone who knows or has Solar Panels?
In my experience the snow usually slides off by itself. There have been times when it's snowed heavily and I've had to clean it off but it does not tend to be the norm.
Q:Do solar panels steal sunlight from nearby plants?
Solar panels only intercept the light that hits them - they can't attract light rays. So, if you had your panels mounted on the ground, the area in shadow behind the panel would receive less light, making it more difficult for some plants to grow there. This would only be a problem if we start seeing massive solar farms appearing. They could potentially displace farmland or natural habitats in some of the sunny areas of the world. A panel on a roof, however, would only stop light hitting your roof tiles - no great loss!
Q:How effective are solar panels now in N E with our 40+ snowfall this month?
Green energy magically makes the snow transparent. The more I learn about solar and wind, particularly selling excess power back to the utility, the less sense it makes. You'll have noticed, perhaps, that there was no way to store the power from the panels for when it's really needed.
