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: Solar panels do good more then bad?
- Sure your proper, sunlight panels (photovoltics) could be used to make electricity for small electronics. Proper now sun cells are on many calculators, and even flashlight. However the trouble is the lenght of time the cells take to charge the gadget, verses the vigour demand. I don;t consider the scale of the panels, and the period of time needed to charge the device are sensible. One think i've been thinking is that all should have a photovoltaic panel to charge a battery. Then, use the battery to cost phone telephones, MP3 palyers. The panel and the battery would be in regards to the 8 x eleven inches, and could sit down in window, or on a dash board to get charged, then utilized in doorways over night to charge contraptions.
- Q: Hi, i want to please a solar panel in Lima Peru, my Latitude is -2 and longitude -77. I understand that since i am in the southern hemisphere, my panel should be pointing north. However, i am using a program called pvdesigner, and according to this, y should face my panel with and azimuth of 00degrees (0 = south) and a tilt of 60degrees. Does this make any sense?thanks
- Typically, solar panels are installed facing the same as your latitude = 2 degrees to the North measured from horizontal. 60 degrees from vertical = 30 degrees from horzontal will give almost as much power in June as in December = beginning of Summer. You can face your panels straight up = zero tilt from vertical = better for December/ not so good in June. Usually, the same tilt as your North facing roof is best as it simplifies installation and reduces wind loading. Shade from trees etc will much reduce the power you get. Neil
- Q: Are there any noise concerns with solar panels?
- No, there are no noise concerns with solar panels. Solar panels produce electricity by converting sunlight into energy and do not generate any noise during their operation.
- Q: Do solar panels require a battery backup system?
- No, solar panels do not necessarily require a battery backup system. Solar panels generate electricity from sunlight, but without a battery backup, the excess energy produced during the day is typically fed back into the grid. However, a battery backup system can be useful in areas with frequent power outages or for those who want to store and use the solar energy generated during the night or when the grid is down.
- Q: Can solar panels be installed in shaded areas?
- Solar panels can be installed in shaded areas, but their efficiency and power output will be significantly reduced compared to panels installed in direct sunlight.
- Q: hi so im doing a school project thing and they have a lot of different questions for us that help us decide whether we would rather a city have a nuclear reactor, or solar panel. But i cant seem to get the last 2 questions...help please???so question ........What types of emissions, if any, are produced by each type of generating station? Do these emissions affect human health?question 2.....What are the long term financial costs associated with maintaining each type of generating station?thanks!
- : Mostly produce heat 2: Keep Clean, trim branches, over hanging shrubs, and things like that.
- Q: I live in Los Angeles area, I see the ads that, they will install solar panel for $0. I would like to know what is the catch ?Thanks You.
- Generally, you still get charged for the panels themselves, just the install is free, or they might make you buy a specific amount to get the install free.
- Q: how much do solar panels cost?
- The silicon ones(last 5 to 25 years) run about $4-$5 a watt the amorphous (thin film) a little less (may last 5-0 years). If you use megawatt hour (000 kilowatt hr) a month you will need at least 3000 watts minimum. Therefore if your electric is .0 per kilowatt hr( $00 per month) the payback is around 25 years once you add the batteries plus inverters(batteries $50-$00 each)(synchronous inverter $3000 to$20000)(ie $5.00/.0=50 months at optimum output).Figure (depending where you live) probably only 50% so break even is usualy about 20 yrs.Ie you pay 20 years electric bill and hope nothing breaks(insurance not included) then you can start saveing money.
- Q: Can solar panels be installed on a military base?
- Yes, solar panels can be installed on a military base. In fact, many military bases around the world have already implemented solar energy systems as part of their efforts to reduce dependence on fossil fuels and increase sustainability. Solar panels can be installed on rooftops, parking lots, or open grounds of military bases to generate clean renewable energy.
- Q: The inverter I am using gets the required 2 DC volts from the solar panel, but fo some reason it just won't output the 0 AC voltage. When the inverter is hooked to a car battery, it works just fine off the same 2 DC rating. Help me out please...
- There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
