Q:Can solar panels be installed in urban areas?
Yes, solar panels can be installed in urban areas. In fact, urban areas provide ample opportunities for solar panel installations on rooftops, parking lots, and other available spaces. With advancements in technology and design, urban solar installations have become more efficient and aesthetically pleasing, contributing to the overall sustainability and energy independence of cities.
Q:Do solar panels require a backup generator?
No, solar panels do not require a backup generator as they generate electricity directly from sunlight, eliminating the need for external power sources.
Q:I am looking to wire in some solar panels into my home. I already have plenty of wiring, and some solar panels around. I just need to know what I need to do to wire them into my home so I can lower my electric bill. This past month it was six hundred dollars.Can someone direct me to some information, or tell me how without telling me to hire some guy to come out to charge me thirty thousand dollars to install two or three thousand dollars worth of equipment?
The essentials are to connect the panels in a configuration that matches the inverter. My system has twenty 24 volt panels in series, to an inverter that wants to see 480. They could have been in any series-parallel configuration to match an inverter that used different voltage. I chose the high voltage route to reduce IR losses in the connections. The proper inverter is essential on grid connected systems. It must be able to disconnect from the grid if grid power fails, and to come back on line automatically, and in phase. There has to be a fused disconnect between the panels and the inverter. When connecting to the grid, another fused disconnect is required. My power company was very specific about acceptable switches. Just using a good brand doesn't hack it. Lots of good info on solar panels in the green search box above on this page.
Q:I am thinking of buying a 3w solar panel called the nomad 3 from goal zero. I want to charge 35Wh lithum batteries. I have heard that lithium batteries are temperatmental and without a regulated current things could get ugly.I have a couple of chargers that came with the batteries. One is a 2v car charger and another is 0-240v wall charger.Goal zero sell something called a sherpa 50, which contains rechargeable batteries and an inverster and I think they suggest that I charge my batteries indirectly through the Sherpa 50, however, the sherpa 50 is expensive at $200, and seems to have a small capacity, in addition to being extra weight that i don`t want to carry.Electronics geniuses, you are my only hope.
If you want to energy each USB ports on the identical times, It could not be possibble. Your sun panel best provides 2.24 Watts (20V * 0.2A) of energy and you ought to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses out of your regulator(s), you are going to be method over your vigor finances. You'll want extra of a sun panel or less of a load.
Q:What, if any, improvement in efficiency per square foot or meter is realized by a solar panel in space vs. being mounted on the ground where the light is attenuated by the atmosphere?In passing, I found a site that gives an output of .89 watts / 4 in. sq for a particular home-mounted panel.
I'm not sure on the exact numbers of solar panel efficiency, however i do know that at the radius of the Earth we should be receiving about 000W of power per square meter. This value is lessened by the atmosphere to a value closer to 600W per square meter on the Earth's surface. (on a really hot day) That's a 40% drop in power due to the atmosphere. I'm assuming that the solar panels being in space don't affect it's efficiency (as in mechanically). So its power generation should increase by about 40% when in space compared with a ground based panel of the same design. Hope this helps, Sorry it's kinda sketchy info...
Q:I hooked up a 2V solar panel to a small relay. The relay switches at 9V. When I have light shining on the panel it puts out aorund 3-4V, but when I hook it up directly to the relay it drops to V and doesn't switch the relay. Why? and How do I fix it?-2V Mono-Crystalline Solar Panel -JWD 7 4 reed relay
Your solar panel output too little current that cannot be used to power the relay. Change the panel into 2V 500mA type shall work.
Q:Also, what's the solar panel's rate of producing electricity?
I'm okorder /
Q:How much space is needed to install solar panels?
The amount of space required to install solar panels depends on various factors such as the type of solar panels, their efficiency, and the energy needs of the property. Generally, a typical rooftop solar panel system requires about 100-400 square feet of space for every kilowatt (kW) of solar panels. Additionally, open areas or ground-mounted systems may require more substantial space. It is recommended to consult with a solar installation professional who can assess the specific requirements based on the location and energy goals.
Q:How do solar panels affect the property's curb appeal?
Solar panels can enhance the curb appeal of a property by providing a modern and sustainable aesthetic. They showcase the homeowner's commitment to renewable energy, which is increasingly valued by prospective buyers.
Q:Can solar panels be installed on sloped roofs?
Yes, solar panels can be installed on sloped roofs. In fact, sloped roofs are one of the most common locations for solar panel installation. The angle and direction of the roof can affect the efficiency of the panels, but with proper installation techniques, it is possible to maximize their energy generation potential on sloped roofs.
