Q:hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:. Does it really only cost $200 in contrast to $5000 or more?2. How much would it cost to build panels that would energize an entire average household? (washer, dryer, water heater, lights, fans, a/c)3. Is there a place to get the info on how to make them for free instead of paying E4E?4. Are the professional solar panels better? more efficient? 5. Will the electric company in So. Cal. really pay you?6. Do you have to be certified to do this professionally? or an electrician? If so what schools teach it?7. Would wind generators be of any use in So. Cal.? I mean don't you really need to get the fan spinning to get energy?8. Are there any extra unseen costs? (tools, energy converter, ect)9. How much is it to get an electrician to hook you to the grid?0. Is it better to hook to batteries or the grid? Pros, cons, why?
Are there any extra unseen costs? (tools, energy converter, ect). Yes. Batteries or Inter-tie, charge controllers, inspections, wiring, inverter etc. 9. How much is it to get an electrician to hook you to the grid? Call for a quote. 0. Is it better to hook to batteries or the grid? Pros, cons, why? Batteries are expensive and only last several years. Maximum power is limited by the size of the inverter. Grid-tie eliminates the need for batteries but then you have to purchase a very expensive grid-tie inverter.
Q:I don't want to spend a fortune, maybe talking like over $200 but I would like to power my computer, the monitor, my tv, and a small fridge.I looked up the price on some but it does not make any sense to me because it says that it has reached the price of less than $ per watt but if I look up a 20 watt solar panel it is $560 dollars. Why would it not be $20 because they said $ a watt.Where would be the best place to buy the cheapest solar panels?
You are probably better off buying solar cells and making your own solar panel. That is what I plan to do. Figure in the cost of batteries, an inverter, and maybe a charge controller. You will need to test the solar panels to make sure you have enough power to power up everything you have. If not, make additional solar panels, and connect them together. Nevertheless, I think it still might cost way over $200, but I think it is the cheapest way to go.
Q:Main questions: How can I work out the efficiency of a solar panel and how can I work out if the panel is relatively cost-effective? Also what type of solar panels is considered most effiecient?Let's assume that all relative values are available.Secondary question: What type of safety regulations and licenses are required to be fulfiled in order to import solar panels into the EU from non-EU countries?
366 W/square meter on March 2 and tweaked based on lattitude eff = W out/Sun W in there are special heat meters to measure W in ======== IEC 62688 Certification; and UL cert in USA
Q:I'm going to pitch an idead to my school about switching to Solar Energy. What are positive and negative effects of the solar panels?Also what is the cost for installing them into a highschool?How much would the electricity bill decline afterwards?
If you hope to get a solar panel that can run appliances and air conditioning.. then you are not even close to being realistic about what solar panels can do. If you really want to install a solar panel array on your home, then you need to talk to a company in your area that designes and installes them because every installation is different.. so you won't get an answer here on Yahoo. You can expect to spend $20,000 to $30,000 that will provide enough solar power for the average home.
Q:Can solar panels be installed on a stadium or sports arena?
Yes, solar panels can be installed on a stadium or sports arena. In fact, many stadiums and sports arenas around the world have already embraced solar energy by installing solar panels on their rooftops or parking lots. These panels generate clean and renewable energy, helping the facility reduce its carbon footprint and save on electricity costs. Additionally, solar panels on stadiums can also serve as a visible symbol of sustainability, inspiring others to adopt renewable energy solutions.
Q:I want to replace my electricity with solar and wind. I live just right outside the city, the roof about 000 square feet. How many windmills/solar panels would it take to get me off the power grid?
I live in the Southwest where the sun shines almost every day. I got a quote for Solar system to produce about enough to cover my annual usage. My annual average electrical usage costs about $2300, or about $90/MO. The system costs around $30,000 but I can get rebates and some of your tax dollars in subsidies to bring my cost down to under $20,000. I can borrow $20,000 for 3 years at 7% and pay $95/MO, so in 3 years I will have the system paid for. As you can see, I don't start Saving any money for a long time. Maybe the rates will go up in later years which will help, but My friends that have solar systems tell me things like controllers go bad over time and they cost like $3000. Will it ever pay for itself? Maybe. Please note. This still does not get me off the grid. This system will not support things like an electric stove, air conditioning, Pool pump running, etc. so I still need the grid for when these operate and my usage peaks. If I installed a system that would totally support everything 24/7 the cost would be astronomical. If you live in the east, midwest, or NW where you have cloudy days, your economic calculations will be much less favorable I would think, unless your power costs are much higher than mine..
Q:Can solar panels be installed on mountain huts or lodges?
Yes, solar panels can be installed on mountain huts or lodges. In fact, mountainous regions with ample sunlight can be ideal locations for solar panel installations. These panels can harness the sun's energy and convert it into electricity, providing a sustainable and reliable source of power for the huts or lodges.
Q:Can solar panels be installed on a car?
Yes, solar panels can be installed on a car. Solar-powered cars have been developed and are being used as a means of reducing carbon emissions and increasing energy efficiency. These panels are typically mounted on the roof or hood of the car to collect sunlight and convert it into electricity to power the vehicle's functions. However, the amount of energy generated by these panels may be limited, and they are usually used as a supplemental power source rather than the sole means of propulsion.
