- Q:our school spends around $0,000 dollars on energy.we want to know how much money would installing solar panels on the roof save our school.
- What you are really looking for is ROI. Return on investment. If you spend 0K up front how long will it take to recoup that 0k. The answer is too long. Solar panels are not and never have been about saving money. They are about trying to save the planet. So if your school wants to go green then they should do it but the overall cost will be higher.
- Q:Most solar panels (the flat ones that go onto roofs of houses) reject electricity produced by the panels if they are too low in voltage. For example, on a cloudy day, although the panels may still get some sunlight to produce some electricity, it is rejected because its too low in voltage. So, does anyone have any ideas?
- On a day that's really dark, I don't think there is anything that can reasonably be done. The voltage is low because the power coming out of the panels is low. A circuit could step that voltage up, but could not increase the power. According to our user's manual, it takes 30 to 40 watts to run our inverter. So if the panels are putting out more than that, it's worth running the inverter. If not, then it's better to not even run it, so the inverter cuts out. A charge controller for a battery would have similar behavior if well-designed. Our array is large enough that during even relatively dark days, there is enough power so that the inverter won't cut out.
- Q:How much sunlight is needed for solar panels to work?
- Solar panels can generate electricity even with small amounts of sunlight, but they work most efficiently with direct sunlight. Generally, they can still produce energy on cloudy or overcast days, although at a reduced capacity.
- Q:How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?
- Maintenance Of Solar Panels
- Q:I've been looking into solar panels. They are fairly expensive ($35k or so). My state has some rebates and grants available. Is anyone aware of any federal grants and rebates other than the federal tax credit? We are subject to AMT tax and can't take the credit. (Which is ridiculous, is the federal government committed to conservation or aren't they??????)
- Check out what someone did in Oakley, California - Contra Costa Times 22 June 2007 Going Solar Can Pay Off On The Long Run PGE Electric Power Monthly Bill Before Solar = $,200. Home: 2,900 sq. ft. Installation Cost for 6.7 Kilowatt 36-solar cells $46,000 (minus $7,60 State rebate). New Resources Bank, a “green” bank in San Francisco, lend them a, no-fee, no-points, second mortgage at $200 a month less than their previous monthly payments because of their plan to install solar panels. PGE Current Electricity Monthly Bill After Solar = $7.63 after deductions for any excess power produced by solar cell which PGE.is legally required to buy. PGE has not build any new electric power plants in California for years and their profits do not depend on sales volume, Sen. Feinstein introduced a bill to make this a National Law. Poweful interests are against this, perhaps they are foreign companies that hate Americans? Surely, they are not bona fide, red blooded Americans that love all the people in the U. S. of America, you think?
- Q:Can solar panels be installed in areas with high levels of saltwater exposure?
- Yes, solar panels can be installed in areas with high levels of saltwater exposure. However, it is important to choose solar panels that are specifically designed for these conditions and are corrosion-resistant. This may involve using materials like marine-grade aluminum or stainless steel for the panel frames, and ensuring proper sealing and coating to withstand saltwater corrosion. Regular maintenance and cleaning are also necessary to mitigate the effects of salt buildup on the panels.
- Q:Can solar panels be installed on a sloped roof?
- Yes, solar panels can be installed on a sloped roof. In fact, many residential and commercial buildings with sloped roofs have successfully installed solar panels to generate renewable energy. The angle of the slope can affect the efficiency of the panels, but with proper installation and positioning, solar panels can still effectively harness sunlight and produce electricity.
- Q:Do solar panels require cleaning?
- Yes, solar panels do require cleaning to maintain their efficiency. Dust, dirt, bird droppings, and other debris can accumulate on the surface of the panels, blocking sunlight and reducing their ability to generate electricity. Regular cleaning helps ensure optimal performance and maximizes the energy output of solar panels.
- Q:Do solar panels require a backup battery system?
- No, solar panels do not necessarily require a backup battery system. It depends on the specific purpose and setup of the solar panel system.
- Q:solar panels are way too expensive to buy, can they be homemade cheaply? i want at least 500 watts. everyone on the web sells these instructions, but i'd like a link to free info, if it is really possible for a non-sciencey person to make. thank you
- we can walk you threw the process. Materials you will need… A sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot. Two alligator clip leads. A sensitive micro-ammeter that can read currents between 0 50 microamperes. Radio Shack sells small LCD multimeters that will do, but I used a small surplus meter with a needle. An electric stove.
