- 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
- My mum has solar panels and her electricity is still on all the time. If she uses stuff during the day, it doesn't cost her anything, as the panels are generating electricity, but at night if she uses things, then it will cost her coz there's no sun and no electricity being generated. She's still connected to the grid to use electricity but because she's feeding the electricity produced by her solar panels back into the grid the company pays her a certain amount for the no. of Watts that's produced. They cost a lot to install, but as she is generating more than she's using (even taking night time into account) she is being paid more back. e.g. before panels she paid ~?30per month. Now she receives ~?70per month. so she's about ?00 a month better off (coz she's saving the 30 AND being paid the 70 on top of that)! and will therefore gain the money back that she paid in in about 8 years or so. Hope that makes sense!
- Q: Can solar panels be used in areas with high levels of dust storms?
- Yes, solar panels can be used in areas with high levels of dust storms. However, it is important to regularly clean and maintain the panels to ensure optimal performance. Dust storms may cause a temporary decrease in energy production, but it can be mitigated by implementing proper maintenance practices such as cleaning the panels and installing protective measures like dust shields.
- Q: What direction do solar panels usually point? North? East? South? West?
- South in the northern hemisphere. - this gives you sunlight on the panel a major portion of the day without the need for a mechanism to follow the sun or change direction from E to S to W as the day progresses
- Q: If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?
- Solar panels are rated under standard test conditions (STC), a certain amount of light at a certain distance, at a certain temperature, etc. A kW, or kilo watt, is 000 watts. So for the amount of time that the sun meets those conditions, the rate of output is 500 watts. An average location has an average of 5 sun hours a day, the total time that you produce the rated output. Watts is a rate, like miles per hour (mph), how fast it is going. Watt hours, or kilo watt hours (kwh) is a quantity, like miles. So if you drive 50 mph for 5 hours, you went 250 miles (50 mph x 5 hours). If you produce .5kw for 5 hours, you have the potential to produce 7.5kwh a day. Multiply that by 30 days in a month, you get 225kwh a month. In reality you will lose about 30% of the rated power from less than ideal weather, system losses, etc., so it's more like 50kwh a month. You can look at your electric bill to see how many kwh you use a month, maybe around 000kwh, and see what percentage of your usage a system like that can power.

- Q: What is the impact of dust and dirt on solar panels' efficiency?
- Dust and dirt on solar panels can significantly reduce their efficiency. When dust accumulates on the surface of the panels, it blocks sunlight from reaching the photovoltaic cells, thereby reducing the amount of electricity generated. The accumulation of dirt can create a barrier that hinders the panels' ability to absorb sunlight effectively. Regular cleaning and maintenance of solar panels are crucial to ensure optimal efficiency and maximize energy production.
- Q: I recently bought a house with very old solar panels (about 25 years old) that don't appear to work properly. They are supposed to heat the hot water heater but they don't always work, and recently have staretd leaking. So, I have had them turned off and now we're just using electricity to heat the hot water. My question is, is there any tax credit money (stimulus or otherwise) available for people to (a) repair old solar panels or (b) replace them with new ones? How does the credit work?
- Congratulations okorder /
- Q: so i told my dad to buy solar panels and he wants to see how much money u can save we pay $00 and i dont want quot;You don't need solar panelshow much would my fmaily save?
- I would suggest getting more info about solar panels, here's the stuff that could be helpful to you renewableenergyarticles.blogspot....
- Q: Can solar panels be used for powering agricultural equipment?
- Yes, solar panels can be used for powering agricultural equipment. Solar energy can be harnessed and converted into electricity through photovoltaic cells in solar panels. This electricity can then be used to power various agricultural equipment such as water pumps, irrigation systems, electric fences, and even machinery like tractors and harvesters. Solar-powered agricultural equipment offers a sustainable and cost-effective alternative to traditional fossil fuel-powered machinery, reducing both carbon emissions and operating costs for farmers.
- Q: I want to know how many solar panels to use to power my AC and Water heater
- you cant use solar panels to power your house, it would take more than you can afford,and space to mount them and all the equip required to hook it up. what they don,t tell you is you need a Battery bank [24 to 48 batteries], deep cycle a inverter ,[one that will convert 2 volts to 0, at the wattage you need ] a transfer switch, rated at 00 amps wiring, a 45 watt panel is around $300
