Q:i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be: Solar power is expensive power. The costs have been coming down but unless it's the only option or there are government subsidies, it would still be less expensive to buy electricity from the grid. The way you compare the upfront costs of solar power with monthly bills is by the Internal Rate of Return equation or the Net Present Value calculation. Vendors will use the payback periods to try and convince you into a financial decision where they reap all the benefits so you need to learn how to do a proper financial analysis. The average US household uses about 950 kwh per month, unless you are very wealthy, you will not be able to afford enough panels for that and you probably don't have enough roof space. You will have to reduce your power usage as much as possible. Batteries are expensive and inefficient. Lead acid batteries are 95% efficient at discharging but only 50% efficient at charging. A battery based system would not only include the costs of the batteries but would also double the number of panels required. Lead acid batteries have their lives rated at only 20% draws on their capacities, they lose a lot of life with each deep cycle. There are deep cycle batteries which have thicker plates but they are also rated at 20% draw and a deep cycle battery's life would drop to 94% with just one deep cycle draw. This means, it's customary to buy five times your diurnal capacity worth of batteries, fortunately this allows for several cloudy days. If you do want to have deep discharges, buy Nickel Iron batteries. You will want a grid tied system instead where you sell the power you produced to the utility and buy back what you need effectively turning the grid into a 00% efficient battery. Of course, there are costs involved as the utilities would likely charge a monthly fee just to be hooked up so this cost must be taken into account. There is also the risk that the utilities may change their net-metering arrangements on you later.

Q:How much energy can solar panels produce?: The amount of energy solar panels can produce depends on various factors such as the size and efficiency of the panels, the location and climate, and the amount of sunlight available. On average, a typical residential solar panel system can generate anywhere from 4,000 to 8,000 kilowatt-hours (kWh) of electricity per year. However, larger commercial or utility-scale solar installations can produce significantly more energy, potentially reaching several megawatts of power.

Q:What is the maintenance cost of solar panels?: The maintenance cost of solar panels is relatively low. Regular cleaning and inspection are recommended to ensure optimal performance, but typically, the cost of maintenance is minimal compared to the savings generated by solar energy.

Q:Has anyone had roof problems caused by rooftop solar panels?: Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.

Q:how does solar panels work?: Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.

Q:Can solar panels be installed in a remote location?: Yes, solar panels can be installed in remote locations. In fact, remote areas with limited access to electricity grids can greatly benefit from solar panel installations. Solar panels are designed to operate independently and generate electricity from sunlight, making them an ideal solution for off-grid locations. They can be installed in remote areas such as deserts, mountains, or even on boats, providing a reliable and sustainable source of power.

Q:Okay, me and my friends are going to fix up an old trailer that's out in the woods, we want something to be able to run small electric appliances off of, but it's to far to run power to. How can we make a good but cheap homemade solar panel that we could plug things into? The trailer is in more of a field so it gets plenty of sunlight! Thanks for any help! :): Solar panel cannot be home made with household material. It was a high tech product. You need to buy them in market. To suppose electricity for a trailer home, solar system becomes very expensive . A t least few thousands dollar to buy solar panels, storage battery bank, DC to AC inverter, heavy gauge wiring and hardware.

Q:Are solar panels worth the investment?: Yes, solar panels are worth the investment. They not only help reduce electricity bills, but also provide a clean and renewable source of energy. Additionally, they can increase the value of a property and contribute to a greener and more sustainable future.

Q:solar panels or light parts: They make lights that have solar panels built into them. Due to the solar cell, they can sense when it gets dark and thus switch on the light automatically. Look at Northern Tool or Harbor Freight web sites for ideas.

Q:I need to know what the main components of a solar water heater and how they functionThanks if you answer x: Solar water heater consists of solar vacuum tube,water storage tank,supports and other accessories.solar vacuum tube is the key component of a solar water heatert,it absorbs sunlight and convert it to heat energy which heat water in the vacuum tube,hot water rises up,cold water fall down,such natural circution make water hot in the water tank.
