Poly Solar Panel 250W in China with Full Certificate

Q: My hubby and I are waiting to move in to our camper but have to figure out how many solar panels, batteries, etc. to get. I can't find the info per appliance for Watts and amps, but does anyone have a good, general idea of how many Watts it'd take to run the whole shabang? It's a 999, 25-foot Sportsmen tag-a-long, if that helps..It's got the following, and we'd like to run the propane things off of electric:*Refrigerator/freezer*Microwave*Oven/stove*AC/Heat*Will have a tv, phone chargers, laptop charger, but those will be unplugged when not in useThanks so much! It's such a headache.. You get SO MUCH different info from different places.. OI..: With an RV, you can find lithium bromide water chiller based refrigerators and air conditioner that run mostly on propane with just a little bit of electricity for a pump and fans. The oven, stove and heat, you can also run off propane. A Microwave is probably 750 watts but only operates for a few minutes at a time. You'll just have to go through everything item by item and figure out how many watts each one will draw and how long each will run per day to size your solar panel. Don't forget that the sun will only shine for a few hours each day. In general, for a camper, the target isn't to produce all the power you need but to slow down the drain on the battery bank to last till you get back onto the road where the engine can recharge the batteries. Keep in mind that the lithium bromide chiller systems only operate when stationary and level so some people opt for conventional electric systems just for convenience which sounds like what you're trying to do. Best way to figure out how much power each is drawing is by measuring it while in use. It may be worth it to put a meter on the battery bank and go camping one weekend with a generator or put a meter on the main circuit breaker panel and camp where power is provided, just to see what your typical use is. You're far better off running as much as possible from propane.

Q: Can solar panels be used in areas with high levels of rainfall?: Yes, solar panels can be used in areas with high levels of rainfall. While excessive water exposure can affect the performance of solar panels in the short term, modern solar panels are designed to withstand different weather conditions, including rain. Proper installation and maintenance can ensure their efficiency and longevity, even in areas with high rainfall.

Q: this solar panel i saw was for 500 dollars(i get a 25% discount)and i was curious will they produce electricity? or just heat?what do they do?is it a good investment?here is a link to the one i would like, no reviews but it looks new to the site.: You need a plan as to what you are going to with 80 watts of power. 80w at the best, it will usually be less. One problem I have is the limited specs, you don't even know the voltage. And you get a Sharp Module but nothing else is mentioned about it. I wouldn't buy it unless you can get full specs on it and on the Sharp Module. With no specs, it's difficult to get a refund if it is defective. If you are going to store it and use it for an AC appliance, a small one, you will need: a charge controller (to control the charge into the battery) a lead acid battery (to store energy for when the sun is out) an inverter (to convert 2 volts DC into 20 VAC) and all of these cost. .

Q: Can solar panels be used in areas with high levels of volcanic activity?: Yes, solar panels can be used in areas with high levels of volcanic activity. Volcanic activity does not directly affect the functionality of solar panels as long as they are installed safely. However, it is important to consider additional factors such as ash fallout, potential acid rain, and the need for regular cleaning and maintenance due to the volcanic environment.

Q: Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?: I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.

Q: i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be: Budget okorder /

Q: Can solar panels withstand extreme weather conditions?: Yes, solar panels are designed to withstand extreme weather conditions. They are built to be durable and can withstand hail, heavy rains, high winds, and even snow loads. Additionally, they are made with materials that can resist corrosion and damage from prolonged exposure to sunlight.

Q: Interested in buying solar panels to save on electric bill.Any government help plans?: I don't believe that there is any help yet.

Q: Do I need some type of regulator when the batteries are fully charged.?? The Arco Panels voltage is approx 7VDC at 2.5 amps, Should I limited the voltage to 4VDC???. I would like to connect both panels to up to five batteries at one time...???: This Site Might Help You. RE: I have two ARCO M55 solar panels. What do I need to connect to a 2Volt bank of batteries.? Do I need some type of regulator when the batteries are fully charged.? The Arco Panels voltage is approx 7VDC at 2.5 amps, Should I limited the voltage to 4VDC??. I would like to connect both panels to up to five batteries at one time...??

Q: What's your opinion on solar power? More specifically, having panels installed on your roof to reduce your electric bill. I'm having a consultation tomorrow to get more details. I live in the SW, so it's always crazy sunny here. I don't know what the cost will be yet. Is it something you'd consider if the situation was right? If not, why?: Sure. You may be able to get a tax credit for installing, but independently verify what the solar panel guys tell you. And check with the electric utility to see if they actually will buy back any excess electricity you might generate. Solar panels are not cheap so they make the most sense if you plan to stay in the house a long time or think it will enhance the resale value enough to make it worthwhile.
