- Q: Where can I find good instructions to build a cheap solar panel on my own?

- Q: Single crystal solar panels and polycrystalline solar panels
- monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
- Q: So during the day, electricity is on, everything is on and working fine. But at night where there is no sunlight does all the electricity shut down for the night? So there is no light on for me during the night, or I can't watch tv at night? Is it also true that with solar panels, your bills are less expensive. Can someone please tell me these things

- Q: So lets say that Everyday I use ,280 kWh. How many 250 watt solar panels would I buy so that I don't need to buy electricity anymore. Sorry if this sounds stupid, I am doing research on why american homes should become more cost efficient.
- Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.
- Q: Can solar panels be used to power an air conditioning system?
- Yes, solar panels can be used to power an air conditioning system. Solar energy can be converted into electricity, which can then be used to power various appliances including air conditioning units. By harnessing the power of the sun, solar panels can provide a sustainable and cost-effective solution for cooling homes and buildings.
- Q: What controllers and all that stuff do I need for these solar panels. Oh and the the batteries will be rigged up to a big electric motor so please leave information on how to wire the batteries to the motor...THANKS!!! 0 POINTS!
- Many solar panels wired in parallel, 2 volt solar regulator, 2 volt battery e.g. 30 Ah, 240 volt inverter, autotransformer that can go down to 50 volts. There are many parameter to the electric motor missing. AC or DC, current needs for full load. How many watts the motor uses and the number of hours required will influence the solar panel, regulator and inverter specifications.
- Q: Can solar panels be used in cold climates?
- Yes, solar panels can be used in cold climates. In fact, cold temperatures can actually improve the efficiency of solar panels by allowing electrons to flow more easily. However, it is important to ensure that the panels are properly installed and maintained to withstand extreme weather conditions and snow accumulation.
- Q: I've been figuring ways to keep water thawed out this winter, and this bucket seems to be the easiest thing. What kind of set up (solar panel) would I need to feed this 260 watt heated bucket?
- Unfortunately solar panels are low output,generally only 2 volt and very low amperage,so you would need to build a multi panel array with a DC-AC converter all together costing several hundred dollars which would only work during sunlight.Just roughly figuring,about $800. Plan2-Solar charger,battery bank,and DC-AC inverter so it would work 24hrs a day,also several hundred $$. Solar power does just not seem feasible(to me)in this application.By far the cheapest set up here would be an extension cord fromhouse to the bucket.260 watts per hr is a fairly lightweight draw,even not figuring the thermostat's cycling it on and off as needed.Electricity is sold in kilowatt hours(000W/hr).This bucket would use(not allowing for thermostats control lowering it)appx 6000watts or 6KW per day.Depending on your electrical cost per Kwh it would cost very little to run.(In my location appx 50cents a day) or appx the same amount as my computer(325watts total)) Note that that would be a maximum rate,and would actually be less due to thermostat cycling off and on as needed.
- Q: Can solar panels be installed on a winery or vineyard?
- Yes, solar panels can be installed on a winery or vineyard. In fact, many wineries and vineyards around the world have embraced solar energy as a sustainable and cost-effective solution to power their operations. The vast open spaces available on these properties make them ideal for solar panel installations, which can generate clean and renewable electricity to meet the energy demands of the winery or vineyard. Additionally, solar panels can help wineries and vineyards reduce their carbon footprint and lower their energy costs in the long run.
- Q: im trying to experiment with solar panels. so i dont want to buy a huge expensive solar panel if i dont need one.
- They are powered from internal batteries, so what you really want to do is to charge the batteries. Take them one at a time, as they have different power and voltage requirements. Don't try to do them both together, unless you use an inverter. To directly charge a battery from a solar panel, you need to find out the voltage and current requirements for the charge operation. Then find a solar panel with a voltage somewhat higher. the current can be lower, it will just take longer for the charge. You will have to monitor manually the state of charge of the battery(s) to avoid overcharging and damage. Another alternative is to get a solar panel that will supply 2 volts and use that to operate an inverter that will output 20 VAC with AC sockets on it. then you can plug in the battery chargers that you have, and they will handle the batteries correctly. Or you can buy solar panels with built in circuitry to handle the charge control. .
