- Q:I don't remember what number exactly but it's in the single digits. This number represents how efficient solar panels are at capturing the sun's rays and converting it into electricity.Why?
- I don't remember what number exactly but it's in the single digits. This number represents how efficient solar panels are at capturing the sun's rays and converting it into electricity
- Q:Im doing a project and i have to persuade some one that solar pannels are great... help ?
- Solar panels are eco friendly, they produce with out disturbing the enviroment. Instead of having to build dams and kill of species that have water homes we can use the sun as our energy source. im all for solar panels i hope this helps :)
- Q:Can solar panels be installed on a military base?
- Yes, solar panels can be installed on a military base. In fact, many military bases around the world have already implemented solar energy systems as part of their efforts to reduce reliance on fossil fuels and promote renewable energy. Solar panels provide a sustainable and cost-effective source of electricity for various facilities and operations on the base. Additionally, the installation of solar panels on military bases can contribute to energy independence, resiliency, and environmental sustainability.
- Q:Can solar panels be used for powering outdoor signage?
- Yes, solar panels can be used to power outdoor signage. Solar panels harness sunlight and convert it into electricity, making them a sustainable and eco-friendly option for various applications, including outdoor signage.
- Q:Can solar panels be installed on restaurants or food establishments?
- Yes, solar panels can be installed on restaurants or food establishments. In fact, many food establishments have started to embrace solar energy as a sustainable and cost-effective solution to power their operations. Installing solar panels on rooftops or in parking lots can help these establishments reduce their carbon footprint, lower energy costs, and demonstrate their commitment to environmental sustainability.
- Q:Can solar panels be installed on a community center or recreational facility?
- Yes, solar panels can be installed on a community center or recreational facility. Solar panels can provide renewable energy for the building, reducing reliance on fossil fuels and lowering energy costs. Additionally, it can serve as an educational opportunity for the community to learn about sustainable energy practices.
- Q:Can I add more solar panel let say up to 200 watt and adding two 2 volts battery using the same charges controller and power inverter?
- You can wire solar panels in parallel (i.e. positive to positive, negative to negative). Preferably, the panels should be similar to allow the output voltages to track. Otherwise, it may be necessary to include diodes in series with each panel so voltage variations do not have an adverse effect. The other alternative is to have the panels charging individual batteries and then combining the batteries through diodes before using the inverter. This approach would require separate charge controllers for each battery. Not quite as energy efficient as each diode causes a voltage drop (and so a power loss).
- Q:So you know how the bigger the surface area exposed to the heat radiation means the quicker it'll heat up.Is this what happens with solar panels, they have a large surface area exposing to the sun, so they can get more heat?
- Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.
- Q:I've seen a couple homes around my town that have solar power and I live in the Desert, where the sun is shinning and it gets really hot during the summer. We run our air conditioner a lot making our electricity bill high.So I just wanted to know if anyone has or knows anyone that has solar panels? are they worth getting and is it the same as having electricity?
- and, if given the tax credits, you'll see a faster return on investment in CA than I would have in Western PA (I was given a 0 year return number without factoring any tax credits). Plus you'll be doing something good for the environment. My brother put his house for sale which had solar panels for hot water, and was offered good money for the solar panels independent of selling the house. If anyone has a any no answer that doesn't involve the initial expense, I'm looking forward to reading it.
- Q:How does Solar Panel make Electricity ?
- when sunlight hits a solar panel the photons from the light hit a layer in panel that converts it into electrons through conduction, thus making electricity
