- Q:I have to show in a project (a model house) how Solar Panels work. In my model I want to show Solar Panels creating electricity to power a T.V but I need to show how the power gets from the Solar Panels to the T.V. A diagram would be really helpful. Please try and make this as simple as possible as I'm only 3, but try and be specific as well!

- Q:I have a panel that quot;deep breatheproduces at 4% efficiency, what can it power, It's about 4ft by 2ft
- Area is 4' * 2' * (0.3048m/ft)^2 = 0.743m^2. Incoming solar (assuming optimally oriented panel) averages about kW/m^2, so 743W max gross. 4% efficiency yields 300W. Most panels are about 0% - 5% efficient, which is about W. In either case, figure about /2 the theoretical efficiency for about 2 hrs per day. so, you can run something from 50 to 50W about 2hrs per day. Too small for any appliance except maybe a laptop or light bulb. Panels typically make about 2V, not enough to run household stuff anyway. Normally panels are used to charge batteries, then an inverter takes power from the battery to run your appliances. Good luck!
- Q:Can solar panels be used for powering remote monitoring systems?
- Yes, solar panels can be effectively used for powering remote monitoring systems. Due to their ability to generate electricity from sunlight, solar panels provide a reliable and sustainable power source for remote locations where access to grid electricity may be limited or non-existent. By harnessing solar energy, these panels can provide continuous power to remote monitoring systems, enabling them to function and transmit data without the need for traditional electricity sources.
- Q:I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?
- Two things on a regulator: a) It will optimize the charge to the batteries - and thereby distribute the most possible power to your active circuits during the day. b) It will prevent the power from the panels from boiling (no kidding) the batteries - no small thing as they are the second largest investment you have after the panels themselves. This is much more critical if you have sealed or Zero-Maintenance batteries. I strongly suggest that you get a regulator as it will significantly lengthen battery life. Follow the directions on the regulator for optimum input voltage and it will let you know whether all the panels should be in series, parallel or series/parallel. But cutting to the chase, you can certainly gang up panels as needed.
- Q:What is the purpose of solar panels?
- The purpose of solar panels is to convert sunlight into usable electricity, providing a clean and renewable energy source for various applications such as powering homes, buildings, and even vehicles, while reducing dependence on fossil fuels and mitigating environmental impact.
- Q:Can solar panels be installed on a recreational vehicle (RV)?
- Yes, solar panels can be installed on a recreational vehicle (RV). Installing solar panels on an RV allows for the generation of electricity from sunlight, providing a renewable and independent power source while on the go. This is particularly useful for boondocking or camping in remote locations where access to traditional power sources may be limited.
- Q:I am moving to Hawaii and the house we are living in has independent electricity. (solar panels and gas powered generators.)
- You would have some kind of thing that captures the kinetic energy and transfers it to electrical energy so it would run, but, yeah.
- Q:I have made a 5v dc 52watt solar panel and I going to be trying to charger 4 2v dc 55ah batteries. I get about 6 hours of sun on my panel. Spec below, is that a big enough panel to charge the batteries???I have 30 3x6 solar cells wired together Cell Specifications: (Watts): .75 Wp (Amps): 3.5 Imax (Volts): 0.5 V max which is where I got my 5g 52watt max (if math is wrong plz tell me) The Battery type: 2Volt 55.0ah NB Sealed Lead Acid Battery. I am using a mppt solar charger.
- Technically, any solar panel can charge any battery, but it would take quite a long time do do so if it is a large battery. If you are aware of the voltage and either amp or watt rating of the unit that is usually used to charge the battery, the solar panel should have a similar power output to that charger to work well. amps and watts are quite similar, and can be converted with this simple formula: W=watts; V=volts; A=amps; W/V=A; V*A=W; When charging batteries, it is always wise to use less amps than needed, and roughly the same voltage as the battery being charged. The less amps used to charge batteries means the battery will take longer to charge but will last a lot longer in the long-term. Your solar panel should be sufficient to charge the battery, but you should test charge it to see if it works well. I recommend using a multimeter to check the batteries voltage every couple of hours. Once the battery reaches 2v, it should be fully charged. You should also check the amps in case they are not at the expected value (take caution when checking amps with a multimeter, when i do it i always end up melting my multimeter leads). The battery should be fully charged from anywhere between 6-48 hours. if it is charging faster, the solar panel has too much power. if it doesn't charge in this time frame, the solar panel is not powerful enough.
- Q:How many solar panels do you need on your house to power your heater in winter?
- Your house, and probably your yard wouldn't be big enough to hold them. I did this exercise once (not doing it again) for someone who wanted to replace his 6hp outboard motor with a solar powered one. The calculations ended up that he would need something like .5 acres of solar panels to get that much energy. Not happening. That said, an passive solar home, can get a significant amount of warmth from the sun directly. But it doesn't work very well at night, when it's coldest. (wonder why that is... probably a climate scientist could help us with that? -- oh, wait. They say warming doesn't have anything to do with the sun.) Edit. I didn't use theoretical stuff to come up with my numbers, I used the claims of actual off-the-shelf solar panels sold by West Marine, calculated the power, and did the math based on existing panels.
