- Q: I'm thinking of these solar panels that people have on their rooftops in domestic properties. I suppose I mean after how long do you break even with respect to just carrying on without them and getting you electricity from the utilities companies? Or answer in any way you think is pertinent. The more info the better.
- The payback period for a solar PV installation is based upon the cost of the installation compared to the savings achieved. Therefore if you installed a modest set of panels yourself, did not need on site electrical storage and did not have any permitting fees but did enjoy rebates you would be doing better than if the installation costs were high, the solar equipment was expensive, you had to purchase storage batteries, it was costly to maintain and permitting was absurd. On the other side of the equation if your electrical use is high, you perhaps own an EV or you can sell power at a high rate then the costs you will be offsetting will be higher and the payback period will be lower. If your electrical use is minimal, there is no time of use metering available the payback period will be higher. Some of the costs you may be offsetting may not be electrical. If you concurrently purchased an EV then you may be offsetting the cost of gasoline which would be higher than electricity. Overall rebates and incentives play a major role. I have seen payback periods as low as 3 years claimed (commercial installation with special city tax breaks) and as long as over 20. A bell curve would probably find most of the installations in the 7 to 5 year category. A solar thermal installation (for hot water, heating and sometimes AC) is far more efficient and most would be in the range of 2 to 8 years.
- Q: I want to install a solar panel system and our power grid can't work in reverse(so it get its electricity from us). My question is how do you prevent electricity from our panel to go to the grid without disconnecting the grid? How can we also use the grid and the panel at the same time when the panel are not creating enough power?PS dont say ask an electrician
- If you are grid-tied, then a standard solar electric system will always feed back into the grid if you are not utilizing more power in your home than is being generated by the solar panels and inverter system. It is possible that a grid isolation device designed to prevent direct back feeding is available, but haven't heard of one in common use. New laws in most areas of the US are now mandating that utilities allow grid-tied alternative energy systems. Double-check you local laws. Sometimes you can't take the utilities word for truth--most will automatically say 'no' and will only relent when you show up with the law in hand. Unfortunately, some utilities have figured out another way to shut down alternative energy pioneers--they demand multimillion dollar insurance policies covering damage that their equipment could sustain from your little PV system. Technically, they are still in compliance with the law, they just make it impossible for a homeowner to meet their requirements. If you are getting the runaround, go to your state representative for help. It's amazing how contrite those utility people can be when a state senator (or even US Senator) has just sent a letter asking them why they are stonewalling a law-abiding and well-meaning citizen. Good luck, and don't give up!
- 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 much candle lights is required to operate a 205 watt solar panel?
- The intensity of direct sun is about 0,000 foot-candles. It would not be practical to light that many standard candles and put them foot away from the panel, but you could supply that intensity with electric lighting. That's in fact how they establish the power ratings of a given panel; they have a rig that provides a standard test condition of sun.
- Q: About how much would it cost to purchase and install solar panels for the average American house so that the house can be off the power grid and use the same amount of electricity as it normally does?
- I had a survey of my home and it was estimated at $30K with a 30% rebate from the government. It would take about 5 years to pay back the cost. I elected to go solar water heating instead. 2 panels with piping installed to an 80 gallon electric water heater with an internal heat exchanger. One small photo voltaic panel to run the pump. There is ethylene glycol inside the pipe and it circulates and heats the water. Works excellent. I live in Nor-Cal and we get a lot of sun. I need to comment on another statement that photo voltaic cells cost more energy to produce they generate. Maybe once but not true any longer. {Solar cells and energy payback In the 990s, when silicon cells were twice as thick, efficiencies 30% lower than today and lifetimes shorter, it may well have cost more energy to make a cell than it could generate in a lifetime. The energy payback time of a modern photovoltaic module is anywhere from to 20 years (usually under five)[9] depending on the type and where it is used (see net energy gain). This means solar cells can be net energy producers, meaning they generate more energy over their lifetime than the energy expended in producing them}
- Q: Can solar panels be used in areas with high levels of UV radiation?
- Yes, solar panels can be used in areas with high levels of UV radiation. In fact, they are designed to withstand and harness UV rays from the sun to generate electricity. The materials used in solar panels are specifically chosen to endure high UV exposure, ensuring their efficiency and longevity even in such conditions.
- Q: Do I just run the wire from the panel into the charge controller and then to the battery AND can I simultaneously draw energy from the battery while it is being charged by the panel?Is it as simple as hooking it up like that?
- I hope you have some instructions. You need safety switches and fuses in the circuit. What voltage/currents are you running? Don't burn the house down or get electrocuted please. DC can be very dangerous.
- Q: What is the average size of a solar panel?
- The average size of a solar panel is typically around 65 inches by 39 inches, or about 5.4 feet by 3.25 feet. However, the size can vary depending on the manufacturer and the specific model of the solar panel.
- Q: Can solar panels be installed on beach resorts?
- Yes, solar panels can be installed on beach resorts. In fact, beach resorts often have ample sunlight, making them ideal locations for harnessing solar energy. Installing solar panels can help resorts reduce their dependence on traditional energy sources, lower their carbon footprint, and potentially save on energy costs in the long run.
- Q: if i was to put a solar panel (sp) just outside of the earths atmosphere ans another solar panel (sp2) 0km away towards the sun. which one would generate more power (sp or sp2)? and how much more? is there a ratio to work out the power output and distance from the sun? would the 0km distance between the panels make a large difference in power output?many thanks in advance
- there are hundreds of satellites in area with image voltaic panels, yet none of them are designed as ability stations. Transmitting ability employing radio frequencies may be profoundly inefficient. A string of satellites orbiting the Earth may be quite costly. despite if image voltaic ability have been to realize financial viability, we would positioned them on the floor the place shall we use them. Given the quantity of stepped forward renewable components of ability already being developed there is quite no reason to launch a ability plant into area. Wow - watched the youtube video... it quite is conceivable the worst invention ever and that i'm hoping it by no capacity catches on. the final situation we prefer are retards who're too lazy to plug of their telephones dropping electrical energy on rather inefficient on the spot circulate while many aspects of the international are dealing with ability shortages. universal chargers are already undesirable adequate simply by fact they consistently drain electrical energy even while not in use. i'm surely not an environmental saint yet this situation is in basic terms stupid.
