Q:Solar panels and your opinion?
Regarding okorder.com/.. . In Hawaii, solar is going in like crazy, with long backlogs for installation. If it will be a long time until you retire, then there is no rush. The price of technology tends to go down with time, and in fact, solar panels today are less than half the price of what they cost us in 2006. Also, who knows where you'll be living when you retire? If it's Honolulu, the place may already have solar panels. In the woods of the Upper Peninsula of Michigan, it might never be worth it (but look into wind, there).
Q:260 watt solar panels on an rv?
There are many other controllers, you just need to get a sense for the limitations and make sure you are working within them. Controllers are not that hard to hook up, two connections simply go to the battery, plus and minus. Then the other two go to your panel. I like to put a switch at the panel output, leave it off while you are hooking up the panel side wiring of the controller, then when you are sure everything is connected properly, and you have some kind of battery power indicatioon at the controller, throw on the panel switch and see if it is charging. Remember that a panel is a power source, and connecting it to the controller while it is in the sun is like hooking up a car headlight while the lights are turned on. Another option is to wrap the panel in a blanket and put it in the shade while you are connecting it up. Your panel has a max amp rating, Imax, which will likely be around 5 or 6 amps at that voltage and wattage. Number 4 romex will work for that, as well as medium duty AC extension cord wire, if your run is less than 30 feet or so. Take care Steven, Rudydoo
Q:How does a solar panel charge controller work for batteries?
7 Amp Solar Charge Controller
Q:What can you tell me about rebate incentives for residential solar panels in New York state?
Enacted okorder.com Hope that you find the above enclosed information useful. 09/9/20
Q:Solar Panel costs and sizes?
Take a look at the website from Retscreen International. This is a site sponsored by the Canadian government and they have everything that you will ever need to know about renewable energy. Download the free software and then feed in the position of your school (GPS Coordinates) and some data about energy useage. It will then link to the NASA websites to tell you the weather and work out what size of solar panel you need, what direction it should point and what angle it needs to be mounted on. I've used it for the UK, Afghanistan, Iraq, Jordan and other countries - It's brilliant - and its free. It also links to manufacturers websites and so gives you costings. Use this and you are guaranteed to be top of the class
Q:2- 390 W Solar Panel's Series or Parallel?
Q:Are solar panels worth it?
I say yes, I had a system put in a few months ago. I paid $6K and my utility paid $0K. I should break even in about 6 years. The system is guaranteed for 25 years, so I will have at least 9 years of free energy. I went from a bill of around $200 per month to under $20 in the summer. I will pay a little more in the winter months because less daylight, but I don't use as much energy in the winter. Each year electricity goes up an average of 5%, so while my neighbors have a larger bill each month, I'll be staying under $50 for a long time. Even without the rebate I would have a break even time of about 0 years, still 5 years of free energy.
Q:Solar Panels Project?
If okorder.com/ for some ideas.
Q:What kind of Solar Power panel setup do I need for this?
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:Question about commercial solar panels?
they are in a position to be in case you're properly knowledgeable and experienced of their assembly and working function, offered you acquire the comparable severe high quality grade cells and do perfect assembly. probability is robust although that your first a number of could be in hassle-free terms somewhat below par till you rather get the carry of it and strengthen into properly practiced purely because of the fact the pros are. Does take a important volume of grunt paintings although so determine if it rather is great use of a while or in case you will do greater beneficial to earn at your prevalent paintings and pay a professional to do this which they do superb.
