Q: Can solar panels be installed on swimming pools?: Yes, solar panels can be installed on swimming pools. These panels can help heat the pool water using solar energy, reducing the need for traditional heating methods and lowering energy costs.

Q: How much is the cost of solar panels including installation for my home so that I can have low monthly power bills.: You can start as small as 7,500. It all according to how much you want to run off solar and your Environment. You can move into Solar slowly as the technology Improves every six months or so.

Q: What specification of solar panel would I need to power a laptop every day? I would need to use it for about 0 hours or so every day. I don't know anything about solar panels, but I am seriously thinking of getting one now and don't know who to ask.: You will need, A battery to store the electricity from the solar panel. The amount of electricity from the panel varies up and down as things such as clouds, position of the sun, etc. reduce the amount of solar rays hitting the panel. The battery stores it all, the ups and downs, and sends it back out at a steady voltage so you can operate your p.c. / appliance. A minimum of 45 watts solar panel. 60 watts would be preferable. 45 watts will charge a battery in one day under ideal conditions. You turn the panel as the sun moves across the sky, no clouds. 60 watts will charge a battery in one day with out moving and regardless of clouds. A controler to prevent the electricity from flowing backwards from the battery to the solar panel when the sun goes behind a cloud or sets at night and the charge drops below the voltage of the battery. A good controller will tell you the charge condition of your battery so you know when it is too low to operate your p.c. safely. And finally an inverter with True Sine Wave capability to change the electricity from the battery into usuable power for your PC and other electronics. Not all inverters produce true sine wave electricity. The electricity has static in it and will make your pc screen jump around and not function as it should. New digital T.V.'s also require true sine wave electricity to operate. Go the extra cost and get the inverter with true sine wave and be happy with the way your p.c. functions. Figure out how many Watts your p.c. or appliance will draw. and match the Inverter to the need. Do not go too big, as they cost more and consume more of your stored electricity to operate. Save as much electricity as you can. You will be able to operate your p.c. appliance longer. When not using your p.c., you can operate your T.V. or other low watt appliance.

Q: I've been thinking and I'd like to have solar panels installed on my roof at some point to help reduce our electricity consumption- but I live in IL and in the winter it frequently snows. Is there such a thing as heated solar panels so they don't get coated w/ice or snow? Are solar panels even a feasible option in IL? Thank you, Anna: With state incentives that rank behind only a few states (such as the ones typically associated with solar like Florida and California) somebody definitely thinks solar is right for Illinois. (source is first site below) As for the ice and snow the typical strategy is to have a tilt that allows for only limited accumulation and still has good orientation to the sun. This is frequently talked about in articles in the magazines Homepower and Solar today. Homepower has a site online and some items are free (2nd site) Good Luck

Q: Can solar panels be used in remote areas without access to the grid?: Yes, solar panels can be used in remote areas without access to the grid. Solar panels generate electricity by capturing sunlight and converting it into usable energy. This renewable energy source is particularly useful in off-grid locations as it provides a sustainable and independent power supply. With advancements in solar technology and the availability of battery storage systems, solar panels can effectively meet the energy needs of remote areas, even during nighttime or periods of low sunlight. This makes solar panels an ideal solution for powering homes, businesses, and infrastructure in remote locations without grid connectivity.

Q: What is the maintenance cost of solar panels?: The maintenance cost of solar panels is generally low. Routine maintenance such as cleaning the panels and checking for any damage or debris is recommended, which can be done by the owner or a professional. Additionally, occasional inspections and repairs may be required, but these costs are minimal compared to the long-term benefits of using solar energy.

Q: thinking of getting a portable solar panel laptop charger...may be a stupid question but may be a very intelligent one as well ;): If you intend to use your panels inside a plane, answer is: solar panel intended for indoors use would most likely work inside a plane without problems. If you intend to mount your panel outside a plane :) it would actually work better than on the ground - there is more light at high altitudes and above clouds than it is on the ground. I'm not sure what portable in this case means - how big or how small is your panel? Solar panels are known for their low efficiency, so high-power solar panels are too big and too heavy to be used in aeroplanes.

Q: Can solar panels be used in areas with high levels of heatwaves?: Yes, solar panels can be used in areas with high levels of heatwaves. In fact, solar panels can still generate electricity in extreme heat, although their efficiency may decrease slightly due to the temperature increase. However, it's worth noting that high temperatures can also lead to increased energy consumption for cooling, which may offset the benefits of solar energy to some extent. Nevertheless, solar panels remain a viable and sustainable solution for electricity generation in areas with high levels of heatwaves.

Q: How could I find out what the amp output of a solar panel? Specifically, I want to know how many milliamps can the solar panel on a Casio fx-260 put out?: You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.

Q: Can solar panels be installed on residential homes?: Yes, solar panels can be installed on residential homes. In fact, many homeowners choose to install solar panels on their roofs to generate clean and renewable energy for their homes, reducing electricity costs and environmental impact.
