FAQ

Yes, there are several government incentives for installing solar panels. These incentives can vary depending on the country and region, but they often include tax credits, grants, and subsidies. Additionally, some governments may offer net metering programs that allow solar panel owners to sell excess electricity back to the grid, further reducing their energy costs.

Hi, I have in my sailboat 2 2 V batteries. I would like to buy solar panel(s) in order to recharge them. As i am in mexico and there is always high sun . i think it is a good idea.Usage of the batteries is very light . I have found 5-2V pannels with 80mA that fit in the sailboat. I want to know if and how i can have like 5 to 0 of them set together to charge the batteries and what other material would i need.also, i would like to know what happend if the pannels only send on 5V in a 2 V battery? Is it still charging but on 40 % of the capacity a 2 v pannel would charge or its just not doing nothing ?

Taken at face value, it would take about 55 hours to re-charge a dead flat battery. However, you don't get 24hrs/day sunlight. Even worse, the output from a panel is only maximum when the sun is at 90 degrees to the surface. Let's assume you can find some way to track the sun. No battery should be allowed to discharge below about 50% so we can halve the recharge time. I would say about 4 days.

Any recommendations for companies? Any things to look out for?

Yes, solar panels are a great way to save on electricity costs for your home. 4 things I can tell you to look out for are: Make sure you can fit enough solar panels on your house to make a decent saving. If you don't have the roof space then you can't put up enough panels and you might as well not bother. For a medium sized home, I would say that you should go no smaller than 2.2kW in solar panels. If you can fit more then go for it. Make sure that the inverter that is used is big enough. It has to deal with the watts from the solar panels back to the power board to convert it as useable energy. If you have a rebate system where you live then make sure you use it. Where I am we have carbon credits that the government will give you that you use to offset the cost of purchasing solar. Don't fall for gimmicks where a company will promise you that you won't pay electricity every again. In order for that to happen you need to be putting more electricity back in the grid as you are currently using so you either need a huge amount of solar panels or you really need to cut back on what you are currently using.

if u buy solar panels and never take em out of the box for like thirty years will they still work good thirty years after you bought them

I'm answering for conventional silicon solar panels, the only kind I really know. The panels are basically semiconductor, wire, glass, and aluminum housing. The last three, everyone knows have long lifetimes if not exposed to the elements. As for the semiconductor part, the degradation is generally due to exposure to the sun. And even so, some solar panels from the 70's are still working today. Usually, what does them in is failure of a connection due to vibration, degradation of the plastic due to heat, sun, or water exposure, or accidents. The question of how useful the panels would be after 30 years is different, though. I have Germanium transistors from 50 years ago - they're still good, but their specs are really lame by modern standards. And suppose you had a PC from 25 years ago. Original cost, $4000, no hard disk, only runs DOS off a 5 /4 floppy disk. It works great, but except as a curiosity, is it useful? The batteries that most people use to store solar energy are lead-acid. The technology has not changed much in 30 years. If you had such batteries in storage, that had *never* been activated (that it, they were dry, no acid had been added yet), I would not be surprised if they would be fine after that period of time. If the batteries were activated, no, they would not keep. But maybe battery breakthroughs are coming with other chemistries, so those batteries would seem clunky and useless 30 years from now.

Hi, I am very interested in solar panels and would like to know more.Can someone please give me a basic explanation of how solar panels work?Thank you

A solar panel is a panel of a certain material that is very sensitive to light. Now, when you place if out in the sunlight, the photons enter that material, and gets converted to energy in the form of electrostatic electrons. These electrons gets carried away by the small silver wires you see running zig-zag over the panel, and is then used as electronic current. It is actually a lot more intricate and detailed than this, but this is more or less how it works. The reason is works better in sunlight, is simply because sunlight has a lot more energy behind it than lightbulbs and other sources, but they work as well!

It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.

you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .

What are the benefits of solar panel heating?What does it cost for solar panels?any other important facts about it?

I installed a 60watt solar panel on the top of my patio/pergola. This is wired to a charge controller then a battery in my basement. Do I need to run a ground from the solar panel? If so, whats the easiest way to do so? Is a wire attached to the aluminum frame then connected to a foot long rod into the ground enough?

Did you ever evaluate possessing the equipment your self? Why not take all of the tax incentives your self? Why pay an identical fee in 7 years from now? that may not a honest deal. Did you ever verify with them what might ensue once you want to sell your place before the tip of the lease? Our enterprise has put in photograph voltaic panel structures in 8 states in the Northeast and we adore to work out the tip consumer identifying to purchase the photograph voltaic array. we glance on the lease ideas as a final motel if there's a financing situation. the guy who owns it makes the money, short and easy. concerning utilising it whilst the capacity is going down, the inverters can not function whilst there is not any grid capacity. you may proceed to function utilising a battery equipment and yet another inverter, yet that will advance your fee extremely plenty as properly. you should use yet another generator as properly, which may be a less costly fee selection. you want somebody who's staring at on your appropriate interest, and not their very own investor. you've got your equipment value paid returned in basically some years!
