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 want to be more self sufficient and get solar panels for electricity in a small house any tips will help. i need to know how many watts is enough and ect.

To clarify your thinking, ask yourself whether your goal is really to be more self-sufficient, or to save money. For most people, I think when they say they want self-sufficiency, they really mean they want to save money, not pay more. The money-saving route may come through putting in more insulation on the house, or double-pane windows, or energy-efficient appliances. Solar might play a part, but the kind of solar that pays back well (if at all) is the type without batteries. That doesn't give you self-sufficiency - if the power company has a blackout, the solar electric will automatically disconnect. Your power company may offer a free energy audit to help you save money. And if you are interested in pursuing solar electric (or even better, solar hot water), check with a local installer. They can size your system and give you a free quote.

Q:They have been around long enough to be cheaper. Unless they are made out of a natural material that is rare and hard to find, there is no reason why they should be so expensive. On another note, I think that all low power devices like cell phones and even laptops should have solar panels. Even if it is not enough to fully power the device for a long period of time, it will provide some electricity savings and with millions of people saving a little power adds up.

Because most solar cells are made from silicon crystals that is grown very slowly. Growing silicon crystals from pure silicon is an extremely slow and expensive process.

Q:Can solar panels be used to power streetlights or outdoor lighting?

Yes, solar panels can be used to power streetlights or outdoor lighting. Solar panels convert sunlight into electricity, which can be stored in batteries and used to power streetlights or outdoor lighting fixtures during nighttime. This helps to reduce reliance on traditional grid-based electricity and promotes more sustainable and environmentally friendly lighting solutions.

Q:Can solar panels be installed on a warehouse or distribution center?

Yes, solar panels can be installed on a warehouse or distribution center. In fact, these large flat rooftops are ideal locations for solar panel installations due to their ample space and reduced shading. By harnessing solar energy, warehouses and distribution centers can significantly reduce their dependence on traditional grid electricity and lower their carbon footprint.

Q:my dad met a guy representive for a solar panel company at a swapmeet Scam?

Hard to say. Solar panels are becoming more common these days. May want to ask if the vendor is licensed and bonded contractor (if he's doing installation as well as panel sales). Find out the name of the equipment that this guy is selling (panels and other hardware) and do a search. For that matter, get the guys name and do a search on it to see he pops up elsewhere.

Q:How do solar panels affect the roof's structural integrity?

Solar panels do not significantly affect the roof's structural integrity. They are typically lightweight, and their installation involves mounting them securely onto the roof without causing any damage or weakening.

Q:I want to know that, is there any thing likehow much charge we can get per square feet. in a solar panel.let me know.also, I will appreciate if reference are given.

Q:Can solar panels be installed in shaded areas?

Solar panels can be installed in shaded areas, but their efficiency and energy production will be significantly reduced.

Q:I was just wondering what the minimum and maximm charging voltage and ampere is for li ion batteries. If i connect a solar panel, which only gets enough sunshine to generate voltage, will that still charge the battery, or would i have to series connect solar panels until they together reach 3,7volt?

One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
