Q:Hey i am going to build a scale model house and demonstrate how you would use solar panels to provide energy. I am thinking of buying some kit solar panels and wiring up some lights to show how they power the home. Also i might hook up a battery in the house to show how you can store the energy. I might also have a large battery hooked up outside the house to represent a power plant that could provide emergency power. Any ideas or comments would be great. Thanks

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:I live in Los Angeles area, I see the ads that, they will install solar panel for $0. I would like to know what is the catch ?Thanks You.

using solar panel in your life, you can save the electricity bill, also you are saving energy for our later generations. If more and more people are using solar energy, the mother earth will become more beautiful.

Q:This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.

It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.

Q:Can solar panels be installed on community centers or libraries?

Yes, solar panels can be installed on community centers or libraries. In fact, community centers and libraries are often ideal locations for solar panel installation due to their large roof spaces and potential for generating significant amounts of clean energy. Additionally, solar panels on these public buildings can serve as a visible example of renewable energy adoption and can help reduce electricity costs while promoting sustainability within the community.

Q:How do solar panels affect roof weight load?

Solar panels can increase the weight load on a roof, but their impact is generally minimal. The weight of solar panels is usually evenly distributed across the roof surface, and most roofs are designed to handle this additional load without any issues. However, it is recommended to consult with a professional to assess the roof's structural integrity and ensure it can support the added weight of solar panels.

Q:How do solar panels affect the property's long-term financial viability?

Solar panels can positively impact a property's long-term financial viability by reducing or eliminating monthly electricity bills, providing potential revenue through excess energy production, increasing property value, and potentially attracting tax incentives or subsidies.

Q:i used 734 killowatts of power last month, any idea on how many solar panels i would need. What im looking for is to somehow hook up my central air to solar panels.

I had a system installed last year and am very happy with it so far. When I was getting quotes from companies we used a 3 year usage history that I was able to get from my utility. I live in an area that allows me to sell back my excess or let my meter run backwards, which really helps reduce costs. The amount of energy you use and can produce will vary during the year. I had monthly usage under 800 kwh and months over 2000 kwh. I have become more aware of my usage and have made adjustments to appliances and habits to cut my usage down. I installed a 3.74 kw dc system. On average in the summer I generate 35 kwh per day and in the winter I averagae around 2 kwh per day, but I've seen days as low as 2kwh. I don't see the benefit to hooking up a system to specifice appliances for 2 reasons. Your a/c doesn't run non stop, so the energy you produce when the system cycles off is lost. You only produce electricity when the sun is shining on the panels. If you have a cloudy day or it is hot after the sun goes down, you will need to still use household energy. My system doesn't zero out my bill, but it reduces it by about 75% in the summer and at least 50% in the winter. My bills were over $200 many months, my highest summer bill was $20 and highest winter bill was $35. My system cost $26K (less than my pool or hardwood floors), I got a $0K rebate from my utility and a $2K federal tax credit. The fed. tax credit has increased this year to 30% of the total installed price. I should break even in 6-7 years and save well over $50K over the life of the panels.

Q:how much do you think it would cost for installation?i heard that solar panels can store electricity and any excess electricity gets sold back to the electric company. how much money can a home owner make from doing this?do you think solar panels are worth it?

Almost sure that you will discover everything related solar power at www.okorder .

Q:I live in Hawaii and having a solar panel is not a bad idea since we have plenty of sun the only problem is that it cost a lot of money and takes many years before you get your money back. There are kits available where you can make and install your own solar panel and wind turbine but is it bull **** or is it a good deal?

go with wind power
