Q: I have a shed that has wiring run for light bulb and a couple outlets. It is in a dark corner of my yard and at night is kinda creepy to go in with even a flashlight. I am weighing the option/expense of running electricity from the house on an overhead line versus putting up a 45 watt solar panel on the metal roof with inverter, battery etc. Sunlight is good to excellent at the location. Question is - will this be sufficient for the occasional use of light and an outlet? What can I expect? Pros and cons appreciated
For okorder /... Electric power. Rather than an overhead cable you can bury a cable or PVC conduit and power the shed with 20AC. You can easily supply 5 to 30A of 20V AC that supply all of your power needs without the issues and limitations of the Solar system. If your shed is within 200 ft of your home you should be able to power the shed for less than $400 if you do the work.
Q: i see these things all over the internet on how to make 'home made solar panels' but all of them require you to buy the solar cells and nothing tells you how to make your own. So how can you make your own solar cells?

Q: Can solar panels be used to power air conditioning or heating systems?
Yes, solar panels can be used to power both air conditioning and heating systems. Solar panels generate electricity by converting sunlight into energy, which can then be used to power various appliances and systems, including air conditioners and heating units. This allows for more sustainable and environmentally friendly ways of cooling and heating buildings.
Q: Got a small project here in a remote location. There is to be a 2 volt deep cycle battery, the equipment to be powered from battery and solar panel to charge battery. The 2 volt battery puts out 55 AH. the max constant power draw from the equipment to be powered is 7.9 watts. Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight?And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge?Thanks to all the input!
Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight? Maybe theoretically, but you're going to have very little margin for losses and clouds. I'll bet it has very little power when cloudy. 7.9/30 = 0.26. So at 00% efficiency, you'd need it to be charging more than 25% of each 24 hour period. In a summer with long days and a climate with few clouds, you might make it. But I think you're very close to the edge. And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge? For an ideal battery: time = Q V / P time = 55 A h * 2V / 7.9W time = 83 hours So you've got pretty good margin on your battery.
Q: Can solar panels be installed on a shopping mall or retail complex?
Yes, solar panels can be installed on a shopping mall or retail complex. Many shopping malls and retail complexes have large roof spaces that can accommodate solar panels. Installing solar panels on these buildings can help to reduce energy costs, decrease carbon footprint, and demonstrate a commitment to sustainability. Additionally, the solar panels can provide a source of clean and renewable energy to power the operations of the shopping mall or retail complex.
Q: I'm writing a lab and I have to put information about solar panels in it. The history, who started them, why they are useful etc. any good sites that can help me?
Yup, just Google solar panel history and away you go.
Q: Can solar panels be used for irrigation systems?
Yes, solar panels can be used to power irrigation systems. Solar energy can be harnessed by the panels and converted into electricity, which can then be used to run pumps and other components of an irrigation system. This renewable energy source offers a sustainable and cost-effective solution for powering irrigation systems, especially in remote or off-grid areas.
Q: Are solar panels worth it?? I mean the price you by for them up front is a lot, so you properly need a loan for it. So how does it work? Won't the loan be just as much as you electric bill?Im just really confused about it.
solar panel is a good product which can use clean energy and convert it into electricity for people use. and will decrease the pollution to the environment.
Q: How do solar panels withstand hail and other extreme weather conditions?
Solar panels are designed to withstand hail and extreme weather conditions through their durable construction and protective measures. They are built with tempered glass that can resist impact and damage from hail. Additionally, solar panels undergo rigorous testing to ensure they can withstand high winds, heavy snow loads, and extreme temperatures. The frames and mounting systems are also engineered to provide stability and withstand harsh weather conditions.
Q: Can I use a regulator from a car to regulate the voltage from a solar panel to a battery?
solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
