5. Q: Do you accept custom design on size?
    A: Yes, if the size is reasonable.

Q: Can solar panels be used to power an entire home?: Yes, solar panels can be used to power an entire home. By installing a sufficient number of solar panels and utilizing energy storage systems, a home can generate and store enough electricity from the sun to meet all its power needs, even during periods of low sunlight or at night. This allows for a sustainable and independent energy source, reducing reliance on traditional power grids and lowering electricity bills.

Q: What are the maintenance requirements for solar panels?: The maintenance requirements for solar panels typically involve regular cleaning to remove dirt and debris, as well as ensuring that they are not shaded by nearby trees or structures. Additionally, occasional inspections for any signs of damage or malfunction are recommended, and if necessary, repairs or replacements may need to be carried out by a professional. Overall, solar panels are known for their low maintenance needs, making them a cost-effective and sustainable energy solution.

Q: Can solar panels be used for charging batteries?: Yes, solar panels can be used for charging batteries. Solar panels convert sunlight into electricity, which can then be stored in batteries for later use. This is a popular and sustainable method for powering various devices and systems, especially in remote areas or during power outages.

Q: first of all, to be honest i have totally no idea on how a solar panel works.my task is to design something like a solar powered street lamp which store sun energy during day time and convert it into electrical energy then light energy so that the lamp can work during night time.any ideas on how to design the solar panel? which can store enough or more enegry in case there is no sunlight another day. and low cost as well :D: solar panels change light into electricity, and do NOT store power. You need a solar panel capable of enough power to keep the light on all night. And that may be 6 hours of sun and 2 hours of dark. Then you need a set of batteries large enough to hold that energy. And a charge controller to regulate the charge into the batteries. And then a light that will operate on the battery voltage, say 2 volts. This is probably not practical due to the large solar panel required, and the large batteries. But here is a few numbers. Assume a 00 watt light at 2 volts. Assume you get at least 6 hours of sun every day and the light will be on for 2 hours. That means the battery has to store 00*2=200 watt hours. divide by 2 and that is 00 amp-hours, a large auto battery size. Allowing for 20% losses in the battery and circuitry, that means you nee 400 watt hours from the solar panel. Since it has 4 hours to operate, that means it has to deliver 400/4 = 350 watts at 5 volts. So there it is: 350 watt panel 00 amp hour battery charge controller sized for above 00 watt light. If you have to allow for a day with no sun, then you need more batteries. Two nights means 2400 watt-hours, two batteries, a larger charge controller and a 2800/4 = 700 watt panel. cost: $400 for batteries $200 for charge controller $2000 for panel .

Q: I don't know anything about solar and what connections that have to be made. any advice and wisdom would be appreciated. thanks: Solar Power For Laptop

Q: Can solar panels be used to power an emergency response center?: Yes, solar panels can be used to power an emergency response center. Solar panels convert sunlight into electricity, providing a sustainable and reliable source of power. By harnessing solar energy, emergency response centers can ensure uninterrupted electricity supply, even during power outages or in remote areas. Additionally, solar panels are environmentally friendly and reduce reliance on traditional energy sources, making them a viable option for powering critical facilities like emergency response centers.

Q: What is a good sight that I could go to about installing solar panels and all of the considerations of it?: Biggest problem is availability of sunshine in the UK. Do you get enough to warrant the fuss or financial layout? Another problem is the orientation of your roof. Facing directly south, with a slope (in degrees) equal to your longitude would be ideal. As far as electricity goes, you have to be tied into the grid to take care of the times you are not generating all the power you need. When you are generating more than you need, you sell it but get paid at the rate the utility normally pays, a lot less than you would pay to buy from them. Still, it's something.

Q: Are solar panels affected by shade?: Yes, solar panels are affected by shade. Shading can significantly reduce the efficiency and overall energy production of solar panels. It is important to ensure that solar panels are installed in areas with minimal shade to maximize their performance.

Q: My plans are building several solar panels and have a battery bank. I want to be able to power the refriderator and freezer and occationaly an electric grill. How would This work exactly and what would the best way to hook this up to make it work? I want to be able to convert DC to AC. How many batterys would I need to make this work. I know when Civil unrest happens I want to be prepared. How would Wind Power work If I can get the equipment I need?: Solar panels and wind/water turbines all produce the energy and feed it into the batteries. Outfeed from the batteries thru an inverter to an electrical panel. From panel to outlets, into which you plug standard appliances and items. You can also get some appliances that run off of 2volt. Check with r.v. companies and suppliers for these. You can also run low voltage wires straight from batteries to switches to lights, fans, etc if you put in 2v ones. Just like your car has lights, fans (ac blower), and radio. As for how many batteries you need will depend upon how much ebergy you will use. You will need to figure how much all of your items use per hour. Then figure how long your charging device could be down for at a time. Solar panels will not charge at all for the 8-2 hours of nightfall depending on your area. Wind turbines will charge day and night so long as wind is of sufficient speed. Water turbines will charge 24/7 so long as water source(creek, stream, river) doesn't run dry. Neccessity/hr=N, time without charging =T. N times T = the amount of backup power you need to get you thru till charging sysytem kicks back in.
