- Q: 200 watt solar panel generates how much watts of electricity per month?
- watts of electricity per month is not a valid measure. You want to know watt-hours per month. A fair assumption may be 5 good hours of sunshine per day, or 50 hours per month. Thus, a 200W panel can produce 30 kilowatt-hours of electricity per month. Many more factors are involved, including your controller, battery charger, wiring, and battery system. At a typical retail rate of $0.5/KWh for electricity, this is worth $4.50 per month. Still, solar power can be cost-effective over the long haul.
- Q: Can solar panels be installed on a south-facing wall?
- Yes, solar panels can be installed on a south-facing wall. In fact, a south-facing wall is often the most ideal location for solar panel installation as it receives the most sunlight throughout the day.
- Q: How can I start working as a solar panel installer/technician without years of education?
- The best suggestion I can give is to call solar installation companies in your area, and ask for their recommendation as to what to do. They may recommend a technical college with an appropriate program. With unemployment rising, new jobs in solar will likely be scarce for a while. You might also inquire at roofing companies. If you apply at a solar company, and can demonstrate that you already have roofing experience, that will be a plus.
- Q: Hi! I bought a Coleman 2 vdc cooler that pulls 9 amps. What size solar panel and amp-hour battery do I need? I only open it 3 times a day. It will hold about 3 gals of milk.
- If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK
- Q: Can solar panels be installed on windows or glass surfaces?
- Yes, solar panels can be installed on windows or glass surfaces. There are specialized solar panels designed specifically for this purpose, known as transparent solar panels or solar windows. These panels are designed to allow light to pass through while still generating electricity.
- Q: Can solar panels be installed on a shaded area?
- Solar panels can be installed in shaded areas, but they won't be as efficient as panels installed in direct sunlight. The amount of shade and the duration of shading throughout the day will impact the overall performance of the solar panels. It is recommended to install solar panels in areas with maximum sunlight exposure for optimal energy production.
- Q: Maximum size of solar panel i have to use is - 8 * 5 feet - this is the limitation given to us.
- go buy some 90's Arco solar panels. they're about 2x5 inches and produce 60 watts (24 volts x 2 amps) in full sunlight. then mount them up on a rig that tracks the path of the sun all day long. not all solar panels are created the same. the ones you get at harbor freight will be less efficient than the ones you buy from some guy whose father got the panel as a gift from a business party in the 990s.
- Q: I'm thinking of getting a solar panel for my house to help cut back on power use (I live in New Mexico). What sort of appliances can I run on a watt solar panel? Is it worth it to get a single watt panel or is it more efficient to get a multi-watt panel?
- You can run a lot of things. If you set the system to charge batteries when you are not using anything, they will charge effectively. You can use the system for lighting, LED lighting direct from the battery power is most effient since LEDs are low voltage devices with a very long life span. I replaced a 2 tube flourescent trough with four 5Watt PowerLEDs for example, While I have it on 20VAC at the moment, I can move it to 2 VDC power with ease, and had set it up to run initially on 2 volt sources. There are also many 2 volt appliances as well. You can even convert some of those all in one stereo systems to operate on 2 volts by eliminating the power supply. You will actually use less power by doing so. You will not be able to blow the shingles off the roof unless you add a Class D amplifier to the output, but for most listening, the output is adequate. Some small TV's these days can be run from 2 volt sources, if not directly, then with a buckboost inverter for a laptop. The small TVs only draw about 30 to 45 Watts. Skip the idea of using an inverter, they are not efficient at small loads, and represent additional load on the system. So with a little bit of planning, you can run a lot from that 60 Watt system. You can at least take some bite out of the electric bill for mundane lighting. You can also use them to keep power up on a battery system for lighting in a remote barn. The uses are only limited by your imagination and creativity.
- Q: how would you build a solar panel
- i'd go to the solar panel store and buy one. It would be /0 the cost of trying to build one in my HOME shop.
