- Q: solar energy
- Building a good solar panel can take you up to a week. To make a solar panel you will need detailed guide including schemes and so on.... There are many guides at the net, but they're not free so you'll have to invest some cash. Typically such guide might cost at about $40 - $90 One of the best is Earth4energy: If you are interested you can read detailed review of this product here:
- Q: what size would the panel be/ I live in the caribbean so plenty of sun!
- I okorder /
- Q: My house uses 500 kw a month, air conditioning is the main consumer, is it possible to install solar panels in my roof to produce this amount, and aproximate cost, thanks .
- here's the cost 50 KW-hr per day. Depending where you live, there is a chart showing the average expected amount of energy from a solar panel based on the panels peak rating. Lets use 5 hours as an average. This means you need 50 kw-hrs over 5 hours or 0 kw of peak performance. The cost to install a complete grid tied system is running from $6 to $9 per watt, depending on size and how your house sits. Typically, for a system this size, $7.5/watt or the total cost is $75,000. The federal government and some state on local government pays part of the cost. Your net cost will be $50,000. If you put $50,000 in a 0 year CD, you'd earn $250 per month in interest. On the average, a 500 kw-hr bill will run $225 per month. In my town it runs $50 and I'd need a larger system because I get less than 5 hours on average. So I'd earn $275 in interest. In CA, your electric bill would be $300.
- Q: Can solar panels be installed on a garage or carport?
- Yes, solar panels can be installed on a garage or carport. In fact, these structures often provide ideal locations for solar panel installation due to their large, flat rooftops or open spaces. Installing solar panels on a garage or carport can help maximize energy generation, reduce electricity bills, and provide shade for vehicles or additional usable space.
- Q: The average solar panel produces 0% of the energy that is put into it. What is happening to the other 90%? Is it being reflected or is it being obsorbed by materials that are not a part of the solar cell? Is it possible to one day have near 00% efficient solar cell technology?
- Unlikely that we gan get to near 00% efficiency, although there is room for improvement. In the meantime, don't pooh-pooh 0% efficiency. That's about the rate of energy transfer up a food pyramid, perhaps a little less at the solar to plant level. As this manages to provide the basis for most of life on earth, it's nothing to sneeze at. As far as the other 90% goes, I would guess that much of it is reflected.
- Q: If you were to shine, for example, heat lamps onto the solar panel along with the sun, will the solar panel eventually not work? Or will they produce more light as long as more light is directed onto them.
- Solar panels do not wear out the way machinery does. The semiconductors used give up electrons by receiving photons, and do not experience a net deficit of particles. However, if you placed a heat source such as a heat lamp too close to a solar panel, you could damage the panel by overheating it, which would denature the semiconductors or cause damage by scorching or melting. The problem would be the heat, not the light. Solar panels do have a finite life expectancy, though it is several decades under normal circumstances. The panels will eventually become scratched, warped, and dented. The electrical conductors will eventually be broken by metal fatigue as the panels heat and cool on a daily basis. So they will die of old age, but they don't wear out in an electrochemical sense.
- Q: I want to be more green and if I get the panels will I still have a regular electric bill?
- The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.
- Q: How do solar panels withstand hail or other weather conditions?
- Solar panels are designed to be durable and can withstand hail and other weather conditions due to their sturdy construction and protective materials. The panels are made with tempered glass, which is highly resistant to impacts, including hail. Additionally, the panels are built to withstand high winds, heavy snow loads, and extreme temperatures. This ensures that they can endure harsh weather conditions without being damaged, allowing them to continue generating electricity efficiently.
- Q: What happens to solar panels during extreme weather conditions?
- Solar panels are designed to withstand a wide range of weather conditions, including extreme weather. However, during severe weather events such as hurricanes or hailstorms, there is a possibility of damage to solar panels. In such cases, the panels may become dislodged, cracked, or shattered. Regular maintenance and proper installation can help minimize the risk of damage, and many solar panels are built to withstand high winds, heavy rain, and even snow.
- Q: Can solar panels be installed on a school or university campus?
- Yes, solar panels can be installed on a school or university campus. Many educational institutions are adopting solar energy as a sustainable and cost-effective solution for their energy needs. Installing solar panels not only reduces greenhouse gas emissions but also provides educational opportunities for students to learn about renewable energy. Additionally, it can save the institution money on electricity bills and potentially generate revenue through excess energy production.
