FAQ:Why install a Solar PV system?
There are many reasons to install a Solar PV system now:
As a low risk investment the returns of between 8-10% net are hard to beat especially during this financial downturn where bank interest rates are below inflation (i.e. money in a savings account even with interest added is actually reducing in value).
Its good for the environment. Installing a small domestic system of around 1.5 kW would provide around 1125 kWh of electricity every year, this would save around half a tonne of CO2 annually.
Electricity can be supplied at the point of use. Reducing strain on our national grid network.
The system will run silently and so will cause minimal disruption.
There is very little maintenance required for a PV system.
After the initial installation costs, there are no further fuel costs.
PV systems are modular, and can be added to at any time.
FAQ:How long will a Solar PV system last?
The MCS accreditation scheme means that all panels installed under the scheme by approved agents will continue to generate for at least 25 years. Over this time their output will diminish slightly but they should still perform at 85% at the 25 year mark according to the scheme rules. Manufacturers have invested heavily to ensure their products meet and in most cases exceed these target
- Q: Hello, I am shopping for solar panels for my home and there are so many to choose from. My house uses 40 Kw of power a day. If you had to choose from the output power of a solar panel from below, which one would you choose and why would you choose it? 2 Volts 4 Amps 48Watts2 Volts 8.5 Amps 02Watts6 Volts 7 Amps 2Watts24 Volts 4.2 Amps 00.8Watts24 Volts 8 Amps 95Watts
- The most energy effiecient PV cell in Australia at the moment is from First Solar they generate the most electricity compared to all units in Australia by an additional 6%. Not much but everything counts these days, especially with prices increasing over the next thress years (even without the CPRS) projections are (by IPART, who are the regulators that sets the electricity prices) rises by 46% (thats by Country Energy) and with the CPRS it was going to reach a 64% increase. The First Solar PV cells will give you a return on investment of around 2.75 years and generate electricity for 25 years (after 20 years they still generate Approx. 85% efficiency - best in market, I know I have been researching them for ages, and these are the ones I am installing !!!. Hope this helps. You need to choose a .5kW system, this will generate Approx $380pa
- Q: If i took a lazier pointer and aimed it a solar panel would it take in the light. Also what types of lights would work on a solar panel like L.E.D, uv light bulbs.
- If you mean a LASER pointer, then the answer is YES. However, the light is concentrated on a very tiny spot, so the panel will NOT generate much. Laser pointers are rated in milliwatts. A typical red laser pointer is rated at maybe 3 milliwatts. So, that is all that will be transferred at MOST. You don't get something for nothing, so the panel MAY put out 3 milliwatts from the laser pointer, but probably less since the solar panel is not 00% efficient. Solar electrical panels rely on sunlight over a large area measured in terms of many square FEET of area. As for driving lamps, the lamps do not care where the power comes from, only that the voltage and current are correct. Most bulbs will work equally well on AC or DC. Solar panels are used to charge batteries, and the batteries are used with an inverter to supply 0 VAC to things like appliances. What you CAN do is use a laser pointer to turn off a photoelectrically controlled light, such as a streetlight, maybe. Many streetlights have a photocell on top which looks at the sky and turns on the light when it is near dark until shortly after dawn. If you can shine a laser on the dome of the photocell, it MAY be bright enough to fool the photocell into thinking it is daylight and turn the streetlight off for a while...
- Q: How much energy can be generated from a solar panel on a clear, bright summer's day for example?
- it depends on the size of the panel and if it is installed in an optimal location. there are many 00W panels commercially available and they can be ganged for a number of different output configurations.
- Q: can this amount of solar charge these batteries.
- 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.
- Q: Can solar panels be installed on a factory or industrial facility?
- Yes, solar panels can be installed on a factory or industrial facility. In fact, many factories and industrial facilities are increasingly adopting solar power as a sustainable and cost-effective energy solution. By installing solar panels, these facilities can reduce their reliance on traditional electricity sources, lower their carbon footprint, and potentially save on energy costs in the long run.
- 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: How much is the cost of solar panels including installation for my home so that I can have low monthly power bills.
- How much it costs, and whether it is worth it, really depends on where you live, and how much power you use. A very conservative house like ours, in an ideal area, could get by with a system that costs $5000 to $7500 net after incentives like tax credits. A house that uses a lot of energy, like a massive one with air conditioning, could need an array costing ten times that much. The only way to even get close on an estimate is to call a local solar installer for a quote. If there are no local solar installers, that's a clue that your area may not be very good for solar. Consider solar hot water also. That's generally cheaper and pays back faster than solar electric.
- Q: The battery is 9ah and the solar panel is 20w
- Yes, certainly. So long as the solar panel's voltage exceeds the voltage of the battery (which is probably going, certainly if it can be a discharged battery, which is lower than 2 volts), then it will recharge the battery. Additionally, a 2 V solar panel can produce bigger than 2 volts. Nevertheless, the rate of charging is more likely to be depdendent on the availabilty of daylight. And of course, the better the capcity of the battery, the longer it takes to cost.
- Q: how much power is generated with solar panels? also please give me links for that information.and how much would the costs be for this alternative energy source?
- KW solar panels generate 5kwh power each day or so.
- Q: i trying to make a solar panel. right now i dont have money to go and buy a copper sheet. so can i make it out of aluminum foil. if there is a way please tell me how. and what do i use for wires. i making this to charge batteries.
- You can't make a solar panel to generate any reasonable amount of electricity from that. You need a semiconductor to start with, in order to have something that can generate free charge carriers(electrons and holes) from photons. Then you need a junction which can separate the charges. In principle you could make a Shottky Diode solar cell from copper if you could find a doped semiconductor to bond a sheet of it to the copper. To form a decent electric field there should be a significant difference in work functions between the copper and the semiconductor, this will generally require the semiconductor to be doped. On top of this you would need a transparent conductor (most used are things like ITO or other 'TCOs' - Transparent Conducting Oxides) to be the top electrode to inject replacement charges into the semiconductor to replace the effect of recombination current. In summary, it's difficult to DIY. You generally need complicated machinery to get decent crystal growth and/or doping.
