Production description
Emerging, third generation solar technologies use advanced thin-film cells. They produce a relatively high-efficiency conversion for the low cost compared to other solar technologies. Also, high-cost, high-efficiency, and close-packed rectangular multi-junction (MJ) cells are preferably used in solar panels on spacecraft, as they offer the highest ratio of generated power per kilogram lifted into space. MJ-cells are compound semiconductors and made of gallium arsenide (GaAs) and other semiconductor materials. Another emerging PV technology using MJ-cells is concentrator photovoltaics (CPV).

- Q: Can solar panels be used for powering construction sites?
- Yes, solar panels can be used to power construction sites. They can provide a sustainable and renewable source of energy, reducing reliance on traditional power sources and minimizing environmental impact. Solar panels can be installed on rooftops, scaffolding, or ground-mounted systems to generate electricity for various construction activities, including powering tools, lighting, and other equipment required on-site.
- Q: Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port, can i just tie the wires together and run into the controller?? Will damage anything...Thanks guys

- Q: If my school uses 88240kWh of electricity per month and I have 000 50W solar panels running for 6 hours a day, does it mean it will take 88240kWh / {{[(50W x 3600s)*000]/000}kWh x 6} number of hours to generate that much electricity (88240kWh)?
- your first question: Does a 50W solar panel generate 540kWh? 540 kW-hr / 50W = 3600 hours it would take that long for the panel to generate that amount of energy. your second question is confused, as you both stipulate the number of hours at 6 hours per day, and you try to solve for the number of hours. 000 x 50w = 50 kW 50 kW x 6 hr/day x 30 day/mo = 27000 kW-hr/mo = 27 MW-hr/mo that is the amount of energy generated. That is nowhere close to 88240 kWh or 88 MW-hr. I would take 7 times more solar panels to generate that much energy. .
- Q: Can solar panels be installed on a hospital or healthcare facility?
- Yes, solar panels can be installed on a hospital or healthcare facility. In fact, many healthcare facilities are increasingly adopting solar energy as a sustainable and cost-effective solution to meet their electricity needs. Solar panels can be installed on rooftops, parking lots, or open land adjacent to the facility, providing clean and renewable energy that can help reduce electricity costs and carbon emissions. Additionally, solar installations can contribute to the facility's green image and commitment to environmental sustainability.
- Q: What is the difference between Photovoltaic Panels and Solar Panels?
- Photovoltaic is a type of solar panel that produces electricity from sunlight, usually converting about 5% - 22% of the energy received from the sun into usuable energy. There are different types including those grown in a lab, silicone, and glass. Another type of solar panel is solar thermal which convert sunlight into heat. This is usually ran into some sort of system that heats water or a mixture w/ glycol in colder regions. This hot water can be used for showers, etc, or heating the home. You get much more bang for your buck with solar thermal.
- Q: Can solar panels be used for heating a greenhouse?
- Yes, solar panels can be used for heating a greenhouse. Solar panels can generate electricity, which can then be used to power heating systems in a greenhouse. Additionally, solar thermal panels can directly capture the sun's heat and transfer it to the greenhouse, providing an efficient and sustainable heating solution.
- Q: How much energy can solar panels produce?
- The amount of energy that solar panels can produce depends on various factors such as the size and efficiency of the panels, the location and climate, and the amount of sunlight available. On average, a typical residential solar panel system can generate between 10 to 20 kilowatt-hours (kWh) of electricity per day. However, larger commercial systems or those installed in regions with abundant sunlight can produce significantly more energy.
- Q: I'm trying to charge rechargeable AA batteries with a solar panel. What gauge wire should I use to connect the panel to the batteries? I know I'm not going to have a lot of current going through so the wire size doesn't really matter. Can the wire be too thick thoShould I ugh? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size diode? My panel is 4.8V 50mA. Can I just hook the panel straight into the batteries or do I need something else?
- In order: .? Just about any wire will do.? You can handle 50 mA over just about anything, even 28 gauge telephone wire.? Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.? You need a diode.? If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.? The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.? You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.? This gives you maximum current output from your panel.
- Q: I live in the UK, I have no savings (so would have to take out a loan of about ?8000), I don't know how long I plan to stay in my house, I might want to move in a year or two to take advantage of a better job so I want to keep the option open of being able to sell my house without having to pay off the cost of having the panels fitted (which I probably won't get back on the increased value they add to my house).What are the main advantages of having solar panels?What are the pitfalls the ever so eager cold callers with quotas to fill don't tell you about?Basically is it worth having them?Thankyou.
- If you're talking about photovoltaic panels, for making electricity, they're very expensive. Around here I think it runs around 2 bucks a watt of capacity, just for the panels. Then they have to be installed of course, which means an electrician has to be paid, and you need an inverter also. You can also spring for a bank of deep cycle batteries if you want to be able to store the electricity from the panels to use at night or on cloudy days, but that adds another very large expense. Now if electricity is very, very expensive where you are, you could maybe pay this off in a few years, but I doubt you could pay off 8000 pounds worth of this stuff in only a couple years. If you're talking about solar for water or air heating, well, that's another deal. But those kind of setups cost a lot less to put in, I can't see anyone paying that much for it.
- Q: My dad owns a restaurant, and we are doing farely well, but we were thinking on installing solar panels to minimize electricity costs (and of course make it greener). My dad would like to hear some numbers on the price in today (August 29/202) and savings he could possibly make over the years. So In Total Here's What I'm Asking:) Would it be hard to install?2) Maintanence?3) Monthly Expense? (None?)4) Price?5) Savings over time?6) Pros/ConsThank you so much!
- not really 2 little 3 very little 4 depends on size of unit 5 depends on how much electricty you use 6 many
