- Q: I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?
- 4 awg wire is good for 5 amps and will handle 9 total panels at 2 volts
- Q: What is the environmental impact of solar panels?
- The environmental impact of solar panels is generally positive. Solar panels produce clean and renewable energy, reducing our reliance on fossil fuels and lowering greenhouse gas emissions. Additionally, solar energy production does not generate air or water pollution. However, the manufacturing and disposal processes of solar panels can have some environmental consequences, including the use of toxic materials and energy-intensive production. Nevertheless, the overall environmental benefits of solar energy outweigh these impacts.
- 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: hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.
- wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
- Q: So I want to go completely solar. Do I need the connected solar panels alone for after sundown hours; Do I need something else in order to have energy to run my entire house throughout the night?In other words do solar panels store the energy for after sun-down or do I need other devices to store the energy?
- solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.
- Q: How hard is it to install solar energy panels on your house? Is this a reasonable way to produce 00% of your house's energy? Is there any danger?
- Yes, but it is still very expensive at the moment. Look into solar leasing where you rent your roof to a company that installs and owns the panels and pays you a portion for surplus energy beyond your usage. I looked into going off the grid a couple years ago and based on our usual consumption it was going to take a $40,000 investment with a 0 year payback for panels, inverter, and storage batteries.
- Q: Me and my friend have made our own functional solar panels for considerably less than retail prices and we are thinking about selling them. Are there any legal issues regarding this? Would I need any special licenses or anything? Would using brand name components or parts in the panels make any difference legally? I want to know before I just go out and start doing it. Thanks!
- you might first patent the design . Make sure everything is well documented . talk to patent agents and lawyers . Then instead of becoming a seller , introduce your design to established companies. They already have all the licences , lawyers, codes..etc to sell , install, advertise to buyers . they can often make you a partner or buy your design for a lump sum . Solar is a huge step . Best wishes
- Q: How much does 000 square feet of solar panels cost? This is for a pool with dimensions 75ft by 25ft? How much will it cost including installation fee and the water heater?
- My Father-in-Law had around 300sqft of solar panels installed for the equivalent of around ?3000 or $5000. These were just the cheap and relatively inefficient black plastic tubes that were installed on his roof. This was in South Africa where the labour rates are quite cheap. The system works okay and heats a 40ft x 20ft outdoor pool to over 30C in the height of summer. Rather than a pool heater, I think it might be good to look at an air source heat pump to help heat the water in Autumn/Winter when you don't get enough sun to heat the pool. These will be expensive (over $5000), but they will use less than 30% of the electricity of a standard electric water heater. Just the solar panels could cost you $5-20K including fitting.
- Q: Can solar panels be damaged by hail or strong winds?
- Yes, solar panels can be damaged by hail or strong winds. Hailstones can cause cracks or fractures in the glass surface of the panels, affecting their efficiency. Additionally, strong winds can potentially dislodge or break the panels if they are not properly installed or secured.
- 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! :)
