Q: Are there any restrictions or regulations regarding solar panel installations?
Yes, there are restrictions and regulations regarding solar panel installations. These can vary depending on the location and jurisdiction. Some common restrictions include obtaining permits, adhering to building codes and zoning regulations, and complying with utility interconnection requirements. It is important to check with local authorities and consult with professionals to ensure compliance with all applicable restrictions and regulations before installing solar panels.
Q: I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?
You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
Q: So lets say that Everyday I use ,280 kWh. How many 250 watt solar panels would I buy so that I don't need to buy electricity anymore. Sorry if this sounds stupid, I am doing research on why american homes should become more cost efficient.

Q: Can solar panels be installed on a rented property?
Yes, solar panels can be installed on a rented property, but it would require the permission of the property owner. It is recommended to discuss the installation with the landlord and reach an agreement on the terms and conditions before proceeding.
Q: my solar panel is 5v 50 mA, and im making iphone USB charger so i need to connect + with 00 ohm resister and to data - and + so what resister will be okay..?
Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.
Q: I was hearing that we need silver as a medal for the creation of solar panels, is this true? How much silver would be needed to make one solar panel? (if this is true)
Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells. Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead. Generally the metal used is in small amounts and not a majority of the cost of the solar panel.
Q: How can I know the right type of solar panel to choose for my small village house in Africa?
The power output of a solar panel uses a formula to determine kilowatts produced per hour per square meter per day. This calculation is important because, if you plan to install a solar power system for your home, you will want to know how many solar panels will be needed. To calculate solar power requirements correctly, you need to gather the data that is needed for the calculation. First you have to find the average amount of solar radiation available for your area. You can use a solar radiation chart. This can range from a 4 to a 7 depending on the area you live in. Write the number down on a piece of paper and indicate it with the letters RA. Next is determine the amount of electricity that you use daily. Add the kilowatt-hours used per month from your utility bill. Multiply this number by ,000 to get the watt hours in a month. Divide the total by 30 for the amount of electricity you use daily. Write this number down and indicate it with the letters DE. Determine the percentage of your home that you want to power with the solar power system. Write this number down and indicate it with the letter P. Determine the system inefficiency factor for the solar power system. You should be able to find this on the brochure for the system or from the manufacturer's web site. Write this number down and indicate it by the letter I. Determine the power or yield that is required for your home. Use the equation P = I x (DE x P) / RA to find the power requirements in kWh. Divide the number from Step 5 by the peak wattage for a single solar panel to determine the number of panels you will need for your home. Goodluck! :)
Q: I have been thinking about getting solar panels for my house. What do you think I should get? Companies? Prices? I also have another question. How much energy can a small solar panel produce?
Jay your info. was very helpful. I'm meeting with a Rep. to see about installing 22 panels on my house, that equals about 6.50 kw system ( May need to add a few more panels ). Need to take advantage of the $ 4,500 Federal tax credit, as well as the $ 6,000 City rebate credit which expires @ the end of 205.
Q: What is the lifespan of a solar panel?
The lifespan of a solar panel typically ranges from 25 to 30 years, although some panels can last even longer with proper maintenance and care.
Q: Can solar panels be used for off-grid living?
Yes, solar panels can be used for off-grid living. They are a popular and sustainable option for generating electricity in remote areas or locations where there is no access to the traditional power grid. Solar panels collect energy from the sun and convert it into usable electricity, which can power various appliances and systems in an off-grid home. Additionally, by incorporating batteries or other energy storage solutions, solar panels can provide a consistent power supply, even during periods of low sunlight or at night.
