- Q: I am curious about how much of the energy that a solar panel of a given size and capacity will produce in it's lifetime, and what fraction of that energy was required to produce it in the first place?
- At present the technology to create silicon solar cells is incredibly energy intensive. It is not logical to compare the cost of oil to the cost of a solar cell because they are not priced according to energy input. Oil has a strong advantage in that it is concentrated solar and geothermal chemical energy that has accumulated over millions of years. The price of oil does not reflect its energy content, but the cost to retreive it. Electrical energy used to produce a Photovoltaic cell is not priced in any proportion to oil. By some calculations it will take about 50,000 KWh of energy produced by the PV cell before it can recover the energy used to manufacture it.
- Q: Can solar panels be installed on a metal roof?
- Yes, solar panels can be installed on a metal roof. In fact, metal roofs are often considered an ideal surface for solar panel installation due to their durability and longevity. The sleek, smooth surface of a metal roof provides an excellent mounting platform for the solar panels, and the panels can be easily attached using specialized mounting brackets designed for metal roofs.
- Q: Can solar panels be used for agricultural purposes?
- Yes, solar panels can be used for agricultural purposes. They can provide power for various agricultural operations such as irrigation systems, livestock watering, grain drying, and greenhouse heating. Additionally, solar panels can help farmers reduce energy costs and dependence on fossil fuels, making them a sustainable and environmentally friendly solution for the agricultural sector.
- Q: where to find used solar panels?
- Used Solar Panels R Us
- Q: Which is more efficient at producing energy? Reference(s) would be nice, but not required.
- Of course solar panels
- Q: What materials are solar panels made of?
- Solar panels are typically made of silicon, which is a semiconductor material, along with other components such as metal frames, glass, and protective layers.
- Q: I own a townhome in the Phoenix area (my power company's SRP, if that makes a difference). Phoenix is a great place for solar. I could probably save money, in the long term, if I got some solar panels.But I am currently extremely broke, so I can't buy solar panels unless I will more or less immediately be paying no more than I am now per month, with little or nothing down. And most of the solar leasing places won't work with me, because (as is common for townhomes) I don't technically own my roof. I have permission to put things on it, but the property management people (or whoever actually owns my roof) won't sign the lease or whatever.Anyone know of either a way to buy solar panels without paying significantly more per month than I already do for electricity, or a solar leasing company that can work with the restrictions I have?
- There are companies who would install solar panels on your roof for no cost. The catch is that they get the power generated for the first 20 years which is the useful life of the panels then you get what's left of the obsolete panels, meanwhile you're required to purchase your power from them at allegedly reduced rates but there is no guarantee that they would remain reduced versus the market once they have you locked in. It's like how the cell phone companies will give you a free cell phone if you sign a contract. Keep in mind that once you've factored in the installation costs and the useful life of the panels, the effective costs of solar photovoltaic energy is about 23 cents to 43 cents a kwh while grid power is about 5 cents per kwh to the consumer, 3 cents per kwh to the utilities for coal generation. It's just that so few people understand how to project an initial capital expense with periodic future returns through discounted cash flow, hence people think solar power is free out of ignorance. Without government incentives, there are no economic benefits to solar and most solar installers structure the sales such that they gain the economic benefit instead of the consumer who is often ignorant of how to calculate the financials.
- Q: i need someone to advice me which solar panels to buy.i have looked into few companies and i need some more info before decidingthe companies i checked were Sun tech trina solar Canadian solar and LDK solar.whice company should i pick?? please help.
- Are you talking about buying panels, or investing in stock? LDK does not make panels, they make solar grade silicon that goes into panels. I haven't heard bad buzz recently about any brand of panel. Therefore, I would go by price per watt alone. If you type in solar panel price into Google, you're sure to get directed to the major sellers, each of whom will sell many brands of panels. There are a couple other requirements that I would have for a serious system: ) Safety certification such as UL. This will be legally required for a grid-tied system. All panels except the really fly-by-night brands and factory seconds have this. 2) 25-year performance warranty. It's standard now for a manufacturer to guarantee that their panel will still produce 80% of the rated output after 25 years. Older panels may say 20 years. Junk panels will have no such warranty, or something ridiculous like 90 days or year. 3) Crystalline silicon. Monocrystalline or polycrystalline doesn't matter. Every few years, someone claims that they have an amorphous or thin-film technology that's durable. Being conservative, I'm still waiting for such things to be proven. Some crystalline panels have been in service since the 70's, although they are pitifully weak by today's standards. I've heard good things about the Sanyo HIT hybrid panels, but that's only from one person who had them installed.

- Q: How do solar panels affect the roof's integrity?
- Solar panels can have a positive impact on a roof's integrity as they act as a protective layer, shielding the roof from various weather conditions. Additionally, solar panels can help extend the lifespan of a roof by reducing direct exposure to sunlight, preventing damage caused by UV rays. However, it is important to ensure proper installation by professionals to avoid any potential issues such as leaks or added weight that could compromise the roof's integrity.
