Yes, solar panels can still be used in areas with high levels of humidity. While high humidity can affect the efficiency of solar panels to some extent, they are designed to withstand various weather conditions, including humidity. However, it is important to note that regular maintenance and cleaning may be required to ensure optimal performance in such environments.

Hi okorder
Have a 20V 40W solar panel and it is attach to two backup batteries. Just want to know know how many watt of inverter do I need?
It depends on what you want to run from the panel. A 20W inverter might last a long time, but would not run much. A 00W inverter might run down your batteries in a few hours. It might help if you posted how much capacity (Volts, Amp-Hours) the batteries have.
Yes, solar panels can be installed on swimming pools. These panels can help heat the pool water using solar energy, reducing the need for traditional heating methods and lowering energy costs.
Hi, wanting to set up the most basic solar panel system for a cabin in the woods that has enough power to recharge four 2V car batteries during the daytime (i am assuming; we want to run a mini fridge maybe a stove and a few lights at night off the batteries and be able to run it all just off solar during the day) It also needs to be able to power some simple tools during the day... Experience would be absolutely amazing since alot of the info on solar paneling is either really dumbed down, or ridiculously confusing.As of right now I am looking at a 3 panel (45watt in all) solar kit that needs a 300w inverter.... is this sufficient for my power needs? I am just a little perplexed, thanks so much!
If okorder / If the minifridge is one that plugs into 2 volts, that should be okay. Anywhere you can eliminate the inverter will help. Such as converting the stereo over to 2 volts. The nominally rated panels should be mounted at an angle to maximize the solar aspect/exposure. Essentially your lattitude plus 2 degrees for simplicity. If you add 60 Watts in panels you will do much better. Your 3 panels when installed correctly will actually yield over 5 Watts each panel at midday. If you do not achieve that, something is wrong in either the wiring, or a panel. It translates to about point2 Amperes to point5 Amperes at midday. If wired in series for 36 volts, the total current output will be same as a single panel (nominal 5 Watt), but at a higher voltage. If wired in parallel, you achieve the 45 Watts at nominal 2 volts. Watts is voltts times Amps. Also converting your tools over to run off the 2 volts will help, Or charging your tool batteries off the 2 volt buss. There are buck/boost circuits that would be capable of charging the common 4.4 and 8. volt tools out there.
Solar panels can significantly improve a property's energy efficiency rating. By harnessing the sun's energy, solar panels generate electricity that can power the property, reducing reliance on traditional energy sources. This results in lower energy consumption and decreased carbon emissions, both of which positively impact the property's energy efficiency rating.
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.
Hello, I have been trying to go green, I Have purchase somesolar panel they are about 45watts I been putting it against my window and getting ok power out of it enough for my lights and a couple of low watts gadget (cellphone, 2v light, portable dvd) for couple of hours.But its seem to drain the 2v faster then I can charge Am I getting the most power out of my panel?Or should I place it on the roof? I'm in Texas and it gets hot and sunny the sun beam my room windows pretty good during 4pm-6pm.
Solar panel generates fairly low, unreliable source of energy. They are most likely very expensive. Despite all of that, your window may act as a beam filter by refracting the beam or reflects them off trough total internal reflection causing a low yield of sunlight harvest. Sunlight is also necessary to hit the panel 90 degrees to harvest maximum output.
