FAQ

i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
Well you are stating the solar panel powers but no mention of their voltage??. Yes, they should do the job. I suspect the lack of blocking diodes may be your problem, assuming you have done the homework. You have 6 battery cells at 2 volts each, that is ...err..2 volts, assuming you have them connected in series. Count the number of cells on the solar panels and maybe we have a starting point. One solar cell is 0.6 v, in this case you would need a minimum of around 30 cells (physically it will probably be 32 to make it 'square'), you need a fair bit of over- sizing in that direction. Solar panels are resistive when not illuminated so must have a blocking diode included to prevent the batteries from discharging into the solar panels at night. Check that each array has a blocking diode included, if not add them. Solar power is pretty useless unless you have loads of sunshine. You seem to have gone through a bit of trouble and expense on this one, so give me some basic facts and I will help you through it. Update 7 Dec If the batteries take 20 hours to fully charge and there are 0 hours of sun each day then the batteries will be fully charged in 2 days. The question was, can the battery be charged, answer is yes, it can. There is no mention of load. If the batteries are not charging there is something wrong.s
Where are solar panels used?
Solar panels are used to help reduce electricity you put them on your roof and you get the suns raze and that turns into solar electricitys
how much does solar panels cost for you home?
I just got a quote for my place. It came out $8/Watt installed. The quote was for 24 - 20W panels. Dividing the total quoted price by the 24 panels comes out to $,750 per panel. This includes the complete system with the converter and cutoff switch to connect it to the grid. This is also a top-of-the-line system. There are cheaper systems with shorter life spans. My quote was for a system with a 30 year life expectancy. There is a Federal tax credit in 2009 of 30% that will bring the system cost down. There are also nice state tax incentives in CA.s

what are the parts of a solar panel?
A solar panel is just a collection of solar cells all wired up in parallel and series to provide a useful voltage. Typical solar cells only provide half a volt, maybe less, so usually you put 2 of them together to get a 6v solar panel or 24 of them to get a 2v panel. Solar cells are made in various ways, the most popular are silicon solar cells which are made with a chunk of silicon with a P-N junction in the middle and contacts on either side. When a photon of light comes in, the energy of the photon is converted to electrical energy. Individually, photons contain a tiny amount of energy, but when you have a solar cell in the sunlight, billions and billions of photons hitting it constantly create a useful amount of electrical energy. Solar panels are incredibly simple!s
Finding the output of a solar panel?
You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.s
Why did the voltage of a solar panel drop significantly after putting it through a step down voltage regulator?
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. .s
