- Q: Single crystal solar panels and polycrystalline solar panels
- Monocrystalline silicon solar cells are mainly made of monocrystalline silicon, compared with other types of solar cells, monocrystalline silicon cell conversion efficiency of the highest. In the early days, monocrystalline silicon solar cells occupied most of the market share, in 1998 after the retreat of polysilicon, the market share accounted for second. Due to the shortage of polysilicon raw materials in recent years, after 2004,
- Q: is a wind turbine better than solar panels
- is your place has enough wind or sunshine ? the turbine is not easily for maintenance. the solar panel is more stable, one broken panel willl not affect the whole system much
- Q: Can solar panels be used to heat water?
- Yes, solar panels can be used to heat water. Solar water heaters use the energy from the sun to heat water, typically through the use of solar thermal collectors. These collectors absorb solar radiation and transfer the heat to a liquid, which is then circulated to heat the water. This renewable and environmentally friendly method can be used for residential and commercial purposes to provide hot water.
- Q: Can solar panels be installed on south-facing windows?
- Yes, solar panels can be installed on south-facing windows as long as the windows receive sufficient sunlight throughout the day.
- Q: What is the impact of dust and dirt on solar panels' efficiency?
- Dust and dirt can significantly impact the efficiency of solar panels. When a layer of dust accumulates on the surface of the panels, it reduces the amount of sunlight reaching the solar cells, thereby reducing their ability to convert sunlight into electricity. This decrease in efficiency can range from a few percentage points to even as much as 20% in extreme cases. Therefore, regular cleaning and maintenance of solar panels are essential to maintain their optimal performance and maximize energy production.
- Q: They absorb solar heat and transform it into electricity, so there should be less heat left to warm the planet. Shouldn't we at least plaster all the world's deserts with them?
- No, the top argument is that extra CO2 is inflicting the ambience to keep greater warmth from the sunlight. Having image voltaic panels might scale returned the quantity of CO2 interior the ambience we are putting in it real now via giving us an means source that doesn't emit CO2, and that's approximately it.
- Q: What is the working principle of solar panels?
- The production of solar cells is mainly based on semiconductor materials, its working principle is the use of optoelectronic materials to absorb light energy after the photoelectricity in the conversion reaction, according to the different materials used, solar cells can be divided into:
- Q: Just curious.
- Solar panels are built with light-sensitive panels. These panels soak up the energy from the sun's light. This energy is changed to electric power. This power is stored in batteries to use whenever / wherever it is needed.
- Q: Can solar panels be used for powering agricultural equipment?
- Yes, solar panels can be used for powering agricultural equipment. Solar energy can be harnessed and converted into electricity through photovoltaic cells in solar panels. This electricity can then be used to power various agricultural equipment such as water pumps, irrigation systems, electric fences, and even machinery like tractors and harvesters. Solar-powered agricultural equipment offers a sustainable and cost-effective alternative to traditional fossil fuel-powered machinery, reducing both carbon emissions and operating costs for farmers.
- Q: hi guys, i need help, okay lets say i decide to put solar panels near a place where its inhabitated by people, what kinda of environmental factors should i consider? Will the solar panels cause any damage to the enviromnent around it? Will it affect the plant and animals around it? should i consider the weather? its for my class so if u guys can help thankx.
- You would need to consider how much sun your area gets on average. You would need to do a cost/benefit analysis to decide if you will be saving money eventually. Environmentally, it would not affect the plants or animals around it, except those it might block the sun from. Meaning, the grass growing in the shade of the panels will probably die out, but that goes for anything that would cast shade for the majority of the time. Solar panels are simply rechargers for the batteries it's hooked up to. No different than a cell phone charger affects the area, people or plants around it. If it is a worry, make some orgonite and place it around the panels. :)
