Q: What materials are solar panels made of?
Solar panels are typically made of silicon, which is a semiconductor material, along with other components such as metal frames, glass, and protective layers.
Q: Can anyone give me a link to a website that sells really big solar panels? Enough to run a small cafe on entirely solar power.
Just google search solar panels or pv panels and you should get a long list of them. That's what I did. Most of the sites selling them will also have the inverters etc that you'll need. Most likely you'll put several small or medium sized panels on your roof - as opposed to just one large one. You probably won't be able to run an entire cafe off of photovoltaic panels, even if you have a bank of batteries. Too many appliances running at the same time. Ask your electric utility company about net metering - you'll buy juice from them when your demand is high and sell to them when your demand is low - IF you can find a sunny day when you're not using juice, but if you have a restaraunt-sized refrigerator you probably won't be selling as much as you're buying. In effect, it won't eliminate your elec bill, just make it a bit smaller. Either way, you may be looking at spending $20,000 to cover the roof with PV panels and your savings won't pay that back any time soon. So, PV is not so great for a business. Much better for a home where you'll be at work all day the only appliances running in your house is your frig. Whatever you invest to solar your house will be repaid when you sell it, meanwhile you'll reduce your bills dramatically, especially if you convert all your indoor lighting to LEDs. On the other hand, the Googleplex, Google's office building full of computers, covered their roof with pv panels and claim to have reduced their monthly bill by /3. BUT, that's a huge building with lots of roof space.
Q: Can solar panels be used in countries with limited sunlight?
Yes, solar panels can still be used in countries with limited sunlight. While solar panels are most effective in areas with abundant sunlight, they can still generate electricity even in regions with less sunlight. Advances in solar technology and the ability to capture diffuse sunlight have made it possible for solar panels to be used in countries with limited sunlight. Additionally, the efficiency of solar panels has improved over time, allowing them to generate electricity even in low-light conditions.
Q: Am using 800watts sukam inverter and have 55watts panel. What controller can i use to connect my solar system to have a max power . Already i have 200 Amp/hr battery
You need a charger Controller but 55 watt panel is not a whole lot of power. So yes you can buy a very good one but it will cost a lot more. For a 55 watt panel you only need a 4 to 7 amp controller. But why not buy a 0 amp so you can add a second solar panel etc... A PWM (Pulse Width Modulated) is the cheapest and most robust type MPPT (Maximum Power Point Tracking) These controllers actually detect the optimum operating voltage and amperage of the solar array and match that with the battery bank. The result is additional 5-30% more power out of your array versus a PWM controller So unless you have a system over 200 watt the PWM works very good I have two of the PWM myself
Q: Can solar panels be installed on concert venues or music festivals?
Yes, solar panels can be installed on concert venues or music festivals. In fact, many event organizers are increasingly adopting solar energy to power their events, reducing their carbon footprint and promoting sustainability. Solar panels can be installed on rooftops, parking lots, or even as temporary structures to generate clean and renewable energy for the venue's electricity needs.
Q: I want to plug my solar system battery bank into my transfer switch on my cabin when not using a generator. The transfer switch will handle 220 volt from my generator. How do I get a 220 volt inverter that runs 60 hz or do all of them run 50 hz.I see plenty of 20 volt 60 hz. I'm at the point of needing to order one and I'm not sure.

Q: i would like to hook up a power outlet to a solar panelmy light system is 500watts will run for 8 hours/day between noon to 8PM.So what is the most effective system do I need?
The least expensive way would be to get a 500 W or preferably a higher rated UPS. The higher the rating, the more robust the inverter. You can get two year old ones cheap because most people don't realize that it's just a $2 battery that goes bad every two years. Get some Car batteries in parallel to build up more capacity. Deep cycle marine batteries or golf cart batteries are best. Connect the Solar Panel to the batteries via a FET diode, assuming your solar cells are wired to produce 2 V or better power (you probably would want at least 8 V), this is to charge the batteries when the sun is shining. A little bit of analog circuitry magic can create a current limiter based on a Darlington pair type layout. Connect the batteries to the rest of the UPS (don't plug it into the wall) and you can run 0 V 60 Hz AC devices off it's outlets. You may want to snip the wire going to the speaker so you won't hear the alarm. There's no way you could sync this to the grid so don't even try a grid tie in and the inverter in the UPS is only intended to run for 0 to 20 minutes so it may burn out however we've run UPS inverters constantly for months before when we needed a cheap power converter to change AC power frequencies before.
Q: Can solar panels be installed on shopping malls or retail centers?
Yes, solar panels can be installed on shopping malls or retail centers. In fact, many commercial buildings are increasingly adopting solar energy systems to reduce their carbon footprint and save on electricity costs. Installing solar panels on shopping malls or retail centers can provide a sustainable and renewable energy source, contributing to their overall green initiatives.
Q: thinking of getting a portable solar panel laptop charger...may be a stupid question but may be a very intelligent one as well ;)
If you intend to use your panels inside a plane, answer is: solar panel intended for indoors use would most likely work inside a plane without problems. If you intend to mount your panel outside a plane :) it would actually work better than on the ground - there is more light at high altitudes and above clouds than it is on the ground. I'm not sure what portable in this case means - how big or how small is your panel? Solar panels are known for their low efficiency, so high-power solar panels are too big and too heavy to be used in aeroplanes.
