product description

 

Currently, polysilicon is commonly used for the conducting gate materials in semiconductor devices such asMOSFETs; however, it has potential for large-scale photovoltaic devices.The abundance, stability, and low toxicity of silicon, combined with the low cost of polysilicon relative to single crystals makes this variety of material attractive for photovoltaic production. Grain size has been shown to have an effect on the efficiency of polycrystalline solar cells. Solar cell efficiency increases with grain size. This effect is due to reduced recombination in the solar cell. Recombination, which is a limiting factor for current in a solar cell, occurs more prevalently at grain boundaries,

Q: What maintenance is required for solar panels?
Regular maintenance for solar panels includes cleaning the surface to remove dirt and debris, inspecting for any damage or loose connections, and monitoring the system's performance to ensure optimal efficiency.
Q: What are the financial benefits of installing solar panels?
Installing solar panels can provide numerous financial benefits. Firstly, solar panels can significantly reduce or eliminate monthly electricity bills as they generate free and sustainable electricity from the sun. This can result in substantial long-term savings, especially in areas with high electricity rates. Moreover, solar panels often have a long lifespan, making them a worthwhile investment. Additionally, many governments and utility companies offer financial incentives such as tax credits, rebates, and net metering programs, further reducing the upfront cost and maximizing the financial return. Lastly, solar panels can increase the value of a property, making it more attractive to potential buyers and potentially yielding a higher resale value. Overall, by installing solar panels, individuals can save money, increase their property value, and contribute to a more sustainable future.
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 a condominium or apartment building?
Yes, solar panels can be installed on a condominium or apartment building.
Q: I have 2 20 watt Solar panel. I have it hooked up to solar controller and batteries to inverter. Am trying to figure out how much watts am getting. I found the voltage but how do I find the amp reading on a mutimeter?
While you can measure voltage on a like without a load, the measure of amperage is more closely related to the amount of power that is being drawn. The amperage is measured with the meter in series (not parallel like voltage) with the load. What it ends up measuring is the load that is being drawn from the solar panel and not the potential of the panel.
Q: How do solar panels affect the property's branding and marketing?
Solar panels can have a positive impact on a property's branding and marketing. By showcasing a commitment to sustainability and renewable energy, solar panels can enhance a property's reputation as an eco-friendly and socially responsible establishment. This can attract environmentally conscious consumers who value green initiatives and differentiate the property from competitors. Additionally, promoting solar panels in marketing materials can help create a unique selling point, increasing brand recognition and appeal to a wider audience.
Q: I would like a list of the solar companies expanding or doing hiring or a good list in general. I know some are expanding. Best answer gets all the points

Q: Dose a solar panel need the entire range or spectrum of sunlight to produce power?
I think it's in the Ultra-Violet range because Solar Panels will still put out almost full power on an overcast day.
Q: Can solar panels be installed on a pergola or awning?
Yes, solar panels can be installed on a pergola or awning. In fact, they can be a great option for maximizing solar energy production while providing shade and protection from the elements.
Q: How do solar panels and heaters work?
