- Q:question about Solar Panels?
- Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!

- Q:Solar panel question..?
- Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
- Q:Why are solar panels only 0% efficient?
- Sunlight comes in many frequencies, that's why it's white. Solar Photovoltaics require a photon to displace an electron from a semiconductor and that only happens at one frequency depending on what the semiconductor material is, therefore only one exact frequency gets turned into power. They are working on using organic dyes or quantum dots to absorb the energy in different frequencies and re-emit the energy in the desired frequency. They also are working on using multiple semiconductor materials to try and capture more frequencies. The rest of the energy becomes heat which also reduces the efficiency of the solar cells. The lab record for solar photovoltaics is 42.8% efficiency and quantum dots promises to be 65% to 75% efficient. Keep in mind that fossil fuels are based on energy collected by photosynthesis over millions of years. The efficiency of photosynthesis with modern plants is about 0.5% and the theoretical maximum efficiency of photosynthesis is 6.6%. All of our current energy use is based upon a small fraction of 0.5% efficiency over millions of years.
- Q:Why dont we have a gigantic solar panel system in the warm states,stretching miles across to supply the usa?
- Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!

- Q:Solar panel question?
- i agree with Liz but have a diffrent point i think u have not calculated for the roof mounted solar panels i am giving youy a bsic understanding hope that will help you Roof Mounted solar power systems consist of solar panels held in place by racks or frames which are attached to roof based mounting supports. Roof based mounting supports include: Pole mounts which are attached directly to the roof structure and may use additional rails for attaching the panel racking or frames. Ballasted footing mounts such as concrete or steel bases that use weight to secure the panel system in position and do not require through penetration. This mounting method allows for decommisison or relocation of solar panel systems with no impact on the roof structure.

- There's no way that home built system that will generate enough power to run your home off the grid. That's all hogwash! No wind = no electricity generated. No sun = no electricity generated. I'm looking into a grid tie solar system. I'm still working out the math for my home. They are expensive ($20k - $50k) before tax credits, but they have been designed by engineers, not back yard, shade tree wanna-be engineers. They will put power into the grid during the day (making your meter run backwards) and you'll draw the power back at night (when there's no sun). This is perfectly legal. It must be installed by power company approved techs. That's how power companies are going to meet their green energy mandates for the future. You'll generate power for the power company and get paid wholesale prices for it (during the day). But you'll buy it back at retail (at night)
