- Q: I am building a solar panel I have wired in series 36 .5 volt solar cells to produce 8 volts I have another panel that has 34 .5 volt solar cells to produce 7 volts. Any issues with wiring these 2 arrays in Parallel? I.E. would the smaller array take usable power away from the larger array?
- yes, i suggest u connect in parallel
- Q: Ok so if i wanted to put a solar panel on my house and i live where it snows, will that be a problem? If the snow covers the solar panel will that be a problem? If so then do i have to climb on my roof and clear it off or what?
- 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: . 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?
- I believe Earth4Energy to be a bald-faced scam, selling plans that will not do what is implied in the marketing, and imparting no information that is not publicly available on the internet, already. If you were to search for solar panel on torrent sites, most likely, some disgruntled customer has posted the material. It probably violates the E4E copyright, so I'm not suggesting that you get it in this manner. I'm going to skip many of your questions, given my already-stated opinion of Earth4Energy. Professionally-installed panels have a net cost of thousands of dollars in general. While they can save money (and Southern Cal is an ideal place for this), consider that it generally takes 0 years or more to get your money back. If you're on S Cal Edison, or SD Gas and Electric, you can go on net metering. They don't really pay you, they credit your electric bill. After a year, if you used more electricity than you generated, you pay them. If you generated more than you used, they reset the balance to zero and say thanks for your donation. You never really get a check, like in some other states. But you should have lower electric bills. You can put up panels for your own use without any certification. To put up panels professionally, you'll need a C-0 contractor's license from the state, or will need to be under the supervision of someone with such a license. But if it's the latter, you might just be the grunt that carries the panels off the truck and up the ladder, for minimum wage. I'd say better than 95% of residentail solar is connected to the grid, if the grid is available. It's a clear winner. Who wants to pay 50% more for their system, just to have batteries that need their water and acid checked all the time? Below is one of many unsatisfied customers from Earth4Energy. Be careful in your search, people selling these reports have bought up the keywords such as scam and ripoff to direct you back to sites selling the product.
- Q: This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.
- It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
- Q: Can anyone give me a link to a website that sells really big solar panels? Enough to run a small cafe on entirely solar power.
- I think you may be surprised how much energy a little cafe like that uses. Since the air conditioning, refrigerators, and other appliances are going nonstop, I'd expect the energy usage to be several times that of a normal house. If you have access to the electric bills of the cafe while it was in operation, look up the kWh's used per month. For scale, I will say that our house uses 500 kWh per month, and needs 3 kW of panels to keep up with that. Scale up to match the restaurant, as a ballpark estimate. If you don't have access to the electric bills, then go visit a similar cafe in town, or a nearby town, and ask them how much their electric bill is. If the ballpark estimate still looks doable to you, then contact a professional solar installer to get an accurate, no-obligation estimate. Most likely, the cafe will use gas heat for cooking. But if not, electricity from solar panels is probably the most inefficient way to cook. Consider having solar ovens for most of the cooking, if you have land, with gas as a backup on cloudy days.
- Q: Can solar panels be installed on south-facing windows?
- Yes, solar panels can be installed on south-facing windows, as long as there is enough sunlight exposure throughout the day. South-facing windows tend to receive the most sunlight, making them a suitable location for solar panel installation. However, it is important to consider any potential obstructions or shading that may affect the panel's efficiency.
- Q: Can solar panels work in the shade?
- The okorder / All solar panels sold by Energy Matters have bypass diodes, which send output from the remaining cells around that dead cell. However, you have lost the output of that cell, so the total panel voltage will drop by about 0.48 volts per cell. Most panels are in the 6 to 8 volt range, and most batteries need at least 3.5 volts to charge completely. So, if 2 or more cells are shaded, the output voltage of the panel may drop too low to charge the battery.
- Q: Why should I have a Generator if I have Solar Panels.....?
- There is now a completely portable (and ultra-high efficient) solar power generator which produces up to 800 watts of household electricity on demand when you need it most. News of this solar backup generator (it's the first off-the-grid breakthrough in 50 years) is spreading like wildfire all across the country!
- Q: Can solar panels be installed on waste treatment plants?
- Yes, solar panels can be installed on waste treatment plants. In fact, many waste treatment plants are increasingly adopting solar energy systems to reduce their reliance on traditional energy sources and lower their carbon footprint. Solar panels can be installed on the rooftops or open land areas of these plants, providing a sustainable and renewable source of electricity for their operations.
- Q: How much Electricity does a standard Solar panel producein terms of Watts and in terms of Units( i.e. electricity meter attached in our House)If I have 20 Solar panels and an inverter , how much electricity will I Be able to harness and store (state that in terms of volts)Can I run Arefridgerator, Iron, Heaters, Plasma T.V. and other high Electricity Consuming Devices.
- Take a look on OKorder at some of the books on how to design solar energy systems. It is a bit more complicated than you might expect. I'm not sure what you consider to be a standard solar panel, but the 3' ones I have produce about 5 watts of power in full sunlight. Put simply, you need to convert the power from the solar cells (variable voltage) into a constant voltage usable for charging a batteries. Most of the low cost modules for this purpose can't handle more than about 00 watts. Larger systems are available that handle thousands of watts but they are quite pricey. Since you can't take out more than you put into your battery system, you can calculate about how long you can run a high-current appliance based upon its wattage rating, that of the battery system (adjusted for loss of converting to AC), and the charging system.
