Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
Q:Can solar panels be installed on commercial buildings?
Yes, solar panels can be installed on commercial buildings. In fact, many businesses and organizations are increasingly opting for solar panel installations to reduce their energy costs and environmental impact. By harnessing sunlight and converting it into electricity, solar panels provide a sustainable and renewable source of power for commercial operations.
Q:what do I need to do to disconnect a solar panel from a battery to protect the panel?
Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
Q:Can solar panels be used in areas with high levels of wind-blown debris?
Yes, solar panels can be used in areas with high levels of wind-blown debris. However, it is important to choose durable and robust solar panels designed to withstand such conditions. Regular cleaning and maintenance might be required to ensure optimal performance and longevity in these environments.
Q:What is the impact of shading on solar panels' performance?
Shading on solar panels significantly reduces their performance as it obstructs the sunlight required for generating electricity. Even a small amount of shading on a single panel can lead to a significant drop in power output for the entire solar system. Hence, it is crucial to ensure that solar panels are installed in areas with minimal shading to maximize their efficiency and effectiveness.
Q:What makes them stop working after a while?
You can search on solar panel failure mechanisms for scholarly works. Amorphous silicon thin-film panels go through an annealing, and power drops off after a couple years. This includes most of those flexible rubber mat type panels. That's why those are not used on serious installations. Serious panels intended for rooftop service generally come with a 25-year warranty, suggesting that the technology is more reliable than your washer, dryer, TV, computer, dishwasher, or water heater. One brand of panel had trouble about 0 years ago, but the manufacturer replaced all that were turned in, even paying shipping both ways. It was a problem with that particular model, not the technology. Our polysilicon panels have been on the roof for 3 years, now, and I've seen no sign of wear, yet, either electrically or mechanically.
Q:Can solar panels be installed on a prison or correctional facility?
Yes, solar panels can be installed on a prison or correctional facility. Installing solar panels can help reduce the facility's reliance on traditional energy sources and lower its carbon footprint. Additionally, it can save money on electricity costs in the long run. However, there may be certain security considerations and regulations that need to be addressed to ensure the panels do not pose any risks or vulnerabilities.
Q:Can solar panels be installed on a carport or parking lot?
Yes, solar panels can be installed on a carport or parking lot. This is known as solar carport or solar parking lot systems. They provide shade for parked vehicles while generating clean and renewable energy.
Q:I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!
If they're just to be used as an example, go around your neighborhood, and find a yard with solar yard lights. Then ask the owner whether you might borrow one or two. If they say no, move on and find another house. I'm pretty sure someone will say yes, after you explain what it's for. They will trust you, because you could have just stolen the lights, but instead asked. Option B is to have your parents take you to Fry's Electronics, and purchase a solar item, like a motion detector light, or even a standalone solar panel. As long as you don't mess up the box, you should be able to return it later for credit. But that's borderline dishonest, because you never intended to keep the merchandise.
Q:I need to power a series of meraki wireless repeaters that plug into a standerd wall outlet. consuming 5v or .08 amps However I need this in a remote location (like out in the middle of nowhere) Using A solar panel as power supply and a battery to store the energy but, how and what do I use to convert the energy coming from the solar panel to the battery and the batteries power supply to match the needs of the meraki wireless repeater? How do I make this as compact as possible? Do I need a ac/dc converter? or dc/ac converter? Any suggestions or solutions would be great !
First things first. 5 Volts @ .08 amps would be .2 Watts. therefore you would need at least the same amount from a solar panel to replenish the batteries. But what puzzles me is the notion that plugging it in a wall outlet ? If you use 20 V @ 0.08 then the power consumption is 9.6 Watts And what is a meraki wireless repeater? I never heard of one. I'm a FCC licensed Ham and have some idea what is available. If you need 5 volts DC, you could use twelve Ni-cads in series and just keep them trickle charged with the solar panel That would make it compact. If you were to use an automotive battery (or motorcycle), then you would need a DC/DC converter.
