- Q:My washer is 20 volts 60 gz,9.6 amps. The solar panels I am looking at are: Sharp ND-208U Solar Panels (208 Watt) List Price $,479.99 Only $,049.99 Sharp Solar Panels (208 Watt) List Price $,352.99 Only $,040.99 If I buy that will it be enough to run my washer?
- Don't you think it kinda depends on the panels? It's not like they're all one size. The A/C units are going to take significant power when in use as will an electric clothes dryer which you failed to mention. And we also have no earthly idea where you live in order to know how many hours of sun you'll be able to rely upon or how frequently you'll need to cool or what the square footage is you're cooling. Are you intending to live completly off grid? If so you'll want to be concerned with battery (which is cost prohibitive) or some other sort of back up for times when the sun isn't out.
- Q:Can solar panels be used to power a construction site?
- Yes, solar panels can be used to power a construction site. By harnessing the sun's energy, solar panels can generate electricity that can be used to power various tools and equipment on the site, reducing the reliance on traditional power sources and lowering carbon emissions. Additionally, solar panels can be easily installed on temporary structures or mounted on portable frames, making them a viable and sustainable option for powering construction sites.
- Q:Can solar panels be installed on parking lots or garages?
- Yes, solar panels can be installed on parking lots or garages. In fact, these locations are ideal for solar panel installations as they provide ample space for the panels and can harness the solar energy efficiently. Additionally, installing solar panels on parking lots or garages can also provide shade for vehicles and reduce energy costs for the facility.
- Q:Can solar panels be damaged by hail?
- Yes, solar panels can be damaged by hail. Hailstones, especially larger ones, can cause cracks or dents in the glass surface of solar panels, which may impair their efficiency and performance. It is important to note that the severity of the damage will depend on the size and speed of the hailstones, as well as the quality and durability of the solar panel materials.
- Q:A local air conditioning company is advertising combining their (newly installed) central air conditioning system for homes, with roof solar panels. They say that the combination MAY reduce your electric bill. Nothing I can see to back-up their claims. Hmmmmm. And they offer, if you can get it; central air conditioning that runs on natural gas. Again, possibly cheaper than using electricity.Has any one actually tested to find out if solar panels and/or natural gas DOES, or DOES NOT save you any money to make it worth the bother?
- Don't do it! It takes years to get your money back. Your better to put the money into insulation and or buying geo thermal unit. I knew someone who install solar panels on his roof to generate hydro and he didn't notice much of a change on his hydro bill and then he had roof problems . Central air units in last 2 years have become very efficient . Almost half the hydro of ones 0 years ago. If you can afford buy a geo thermal unit. It uses the heat of the ground in the winter 2 heat your house during the winter and the coolness of the ground to cool your house. They aren't cheap though. If you plan on living in your house for more than 0 years and have the room in the yard to install then go for it. No how you slice it though AC units use way more hydro than solar panels can produce. You would need about half a football field with a huge battery storage system to run a AC unit. When a company states you might on hydro I would stay away. Also remember they do not tell you about the costs of the upkeep on the solar panels and converter and batteries
- Q:Can solar panels be used in areas with high levels of insect activity?
- Yes, solar panels can be used in areas with high levels of insect activity. While insects may occasionally land on the panels, it does not significantly impair their functionality or efficiency. Regular cleaning and maintenance can help ensure optimal performance and prevent any long-term issues caused by insects.
- Q:What do I need to use this as a battery charger
- I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
- Q:There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?
- Good question. One of the reasons is the greed of manufacturing companies. No matter the profit margin of the product, they seem to want to charge so high a price that the break even point is ten years down the road, so the true savings are few. The cost of solar panels should have dropped way lower than they have by now. I believe that the political correctness of the product will tempt the manufacturers to keep the prices artificially high. One other answerer is right, the panels are very fragile, and damage would destroy the investment, so new inroads need to occur in technology to protect the panels from damage. Somewhere in the middle is a profit for the manufacturers, and savings for the consumer. I hope we find that middle-ground soon.
- Q:I was told by a veteran that jcpl had a program that installs free solar systems for disabled vets.If this is true who do i contact?
- It varies from state to state.
- Q:I need a solar panel for my laptop as i am going camping in the desert, and i need my laptop. There are two choices of solar panels, One is 0 watts and 2 V and maximum power current 0.56 amps. The other one is 2 watts, 2 V and no mention of current. My laptop plug says input 00-240V and .5A and then output 5V-5A. Which one should i get for my laptop. If there are other choices please tell me ill look them up on OKorder.Thanks
- I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
