A: Yes, we can do that.
- 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:We are considering getting solar panels for our home just south of Birmingham, AL. We know a little and are trying to educate ourselves the best we can. But we are having a hard time finding anyone around this area. We have done the yellow page thing, and some quot;green places around town. But to no luck.....
- Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
- Q:Are solar Panels worth it, Do they really quot;save moneyon electricity?
- The answer is yes. Where it used to cost around $0 per watt you can now buy a system installed for half of that. Panels are more powerful, technology is better so once again the answer is yes. In addition a lot of power companies are offering net metering programs (that is where you sell your extra power back to them for credit). It's like putting power in the bank during peak solar days to use when the sun doesn't shine. You stay hooked up to the grid and when you're making more than you're using your meter spins backwards.
- Q:Basically I need a custom solar panel created. I won't go into detail but the dimensions need to be around 4''x2.5'' and be as thin as possible.
- There's no way that home built system that will generate enough power to run your home off the grid. That's all hogwash! No wind = no electricity generated. No sun = no electricity generated. I'm looking into a grid tie solar system. I'm still working out the math for my home. They are expensive ($20k - $50k) before tax credits, but they have been designed by engineers, not back yard, shade tree wanna-be engineers. They will put power into the grid during the day (making your meter run backwards) and you'll draw the power back at night (when there's no sun). This is perfectly legal. It must be installed by power company approved techs. That's how power companies are going to meet their green energy mandates for the future. You'll generate power for the power company and get paid wholesale prices for it (during the day). But you'll buy it back at retail (at night)
- Q:Can solar panels be installed on historical landmarks or monuments?
- Yes, solar panels can be installed on historical landmarks or monuments with careful planning and consideration to preserve the architectural integrity and cultural significance of the site.
- Q:i am very new to the solar world and i need help with some stuff to understand what i need to do.what AH battery should i use? i am planning on getting a 2V deep cycle gel based battery but i want to get the most power for my system so should i use something like a few 00AH in a battery bank system or a bunch or 50 or so amp hour batteries in a bank. also what kind of power am i looking at for the best battery system. in other words what kind of basic appliances like lighting, laptop,space heaters etc can can i run on the selected battery system and for how long? any help would be highly appreciated.

- Q:Hi I need to replace the solar panel on my calculator and was wondering where I could buy one. Thanks in advance for your answers.
- My suggestion is to first make sure that your calculator does not also use a tiny button cell. It could just be that the battery went dead. Also know that it's probably less trouble to just get a whole new calculator. If you have the skills to replace the solar cell, I'd suggest first disconnecting it, and wiring a .5 volt battery in its place. If that doesn't work either, maybe the problem is not the solar cell at all, but just its connection, or even a dirty ON button. As for where to get a replacement solar cell, if it were me, I'd go to a dollar store, and see if they have a cheap solar calculator that I could harvest one from.
- Q:How do solar panels affect the property's corporate social responsibility?
- Solar panels have a positive impact on a property's corporate social responsibility (CSR) by reducing its carbon footprint and reliance on fossil fuels. By generating clean and renewable energy, solar panels contribute to sustainability efforts, promote environmental stewardship, and demonstrate a commitment to reducing greenhouse gas emissions. Additionally, solar panels can enhance the reputation of a property, attract environmentally conscious stakeholders, and align with CSR goals of promoting renewable energy and protecting the planet.
- Q:I have two solar panels and I have measured that they produce V by themselves. I am trying to generate .5V, but whenever I hook them up in parallel I get something like .02V. What it happening?
- . You want series, not parallel. (Add the voltages. Coonect '+' of the first to '-' of the next, and take your feed from the extreme ends.) 2. if you parallel them and you get less voltage than one alone, you got your polarity crossed up and are reading the difference between them.
- Q:For those solar panels that you install on your rooftops, do they generate electricity when it's cloudy? And if yes, how much electricity does it generate compared to sunny days? For example...like only 25% electricity generated compared to sunny days?
- 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.
