Q:Can someone please explain to me the basics of solar panels and power storage/usage?
Okay well solar panels only work under sunlight and it saves alot of electricty as compared to your normal switches.And it also saves money=D.One thing though...it only works under sunlight...remember this fact. Power storage simply means a device which can store power. Well a generator stores power and a power station too!! Otherwise they can't flow through our electric current..... So for power usage simply is like on the fan/lights/mobile/computers/modems/e.t.c are considered as power usage as you are using the power=P Well hope this information helps you!
Q:Is anyone using small solar panels in their home with any practical results?
I have an active solar heater on my roof. During the winter it comes in handy and heats the house, though we still need to use a gas heater to get the temperature up to a comfortable level.
Q:45 Watt Solar Panel -?
Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelish
Q:how to make a solar panel?
All you need to do is to learn how to build solar panel to produce your own electrical energy through solar panels. These solar panels take and keep the energy from the sun and turn it into usable electrical energy that we can use every day in our ordinary lives. Generally, the majority of people that knew about solar panels think that they won't benefit from its use because they just work in sunny areas. That isn’t the case. In fact, the new generation of solar panels can produce a lot of electrical energy even on rainy weathers. Learning how to build solar panel is very easy: first they need to be installed (most of the time, on the roof of homes) and then they take the energy from the rays of sunshine and convert it from solar energy to electrical energy. Solar panels must be kept from shading, as shaded cells draw energy for themselves from other cells. Things you need to know: . Solar panels using monocrystalline cells have high conversion efficiency, and take up less space, but lack shade protection. 2. Solar panels using polycrystalline cells have even higher conversion efficiency, take up even less space, but still lack shade protection. 3. Solar panels using amorphous silicon cells have lower conversion efficiency, and take up more space, but do have shade protection. This can be especially important on a sailboat. Once you have determined the size and number of solar panels needed, you will be better able to determine where they will be placed. The best places depend on the roof's length and size of the panels. Take your time and think it through. The simple answer to how to build solar panel is none other than the sun. Select locations that will get maximum sunlight without shaded spots. In placing solar panels, consider the use of extra bars/braces to secure the panels. You obviously want them to remain stable.
Q:Advice on Solar Panel....................................?

Q:Do homemade solar panels really work?
The technology of the solar panels is way beyond any DIY project. You can buy pre-assembled panels and install them, but you also need the devices to make the DC they generate into the AC your home needs. Also you will need the batteries for the nights and the times when the sun does not shine. Solar/ photo voltaic generation does work but is not a cost effective way to reduce your reliance on the electrical grid as of this time. They cost 2 arms and a leg, and take many years to come close to break even on the electrical savings. Do a search on the amount of power each panel will generate and then compute how much power you need and what the costs are. I believe in solar power, but not for an individual residence is it practical. Good luck.
Q:Is there any way I can get solar panels with my restrictions?
There are companies who would install solar panels on your roof for no cost. The catch is that they get the power generated for the first 20 years which is the useful life of the panels then you get what's left of the obsolete panels, meanwhile you're required to purchase your power from them at allegedly reduced rates but there is no guarantee that they would remain reduced versus the market once they have you locked in. It's like how the cell phone companies will give you a free cell phone if you sign a contract. Keep in mind that once you've factored in the installation costs and the useful life of the panels, the effective costs of solar photovoltaic energy is about 23 cents to 43 cents a kwh while grid power is about 5 cents per kwh to the consumer, 3 cents per kwh to the utilities for coal generation. It's just that so few people understand how to project an initial capital expense with periodic future returns through discounted cash flow, hence people think solar power is free out of ignorance. Without government incentives, there are no economic benefits to solar and most solar installers structure the sales such that they gain the economic benefit instead of the consumer who is often ignorant of how to calculate the financials.
Q:2- 390 W Solar Panel's Series or Parallel?
Q:Connecting solar panel help?
never hook up solar panels in series, you reduce the total power produced, and may hurt them, only voltage out, never voltage in. Don't forget to vote for best answer!
Q:Do solar panels generate power when it's cloudy?
No, silicon photovoltaics reacts to a very specific frequency of infrared light which matches the bandgap energy of it's outer electron shell. This frequency is reflected by clouds. However, thermal solar collectors such as evacuated tube collectors can function under cloudy skies albeit at a lower rate and there is at least one hybrid photovoltaic and thermal panel designed to take advantage of this.
