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:Which Solar Panel Type is best? Polycrystalline panel or PV Module Monocrystalline Solar cell panel, or thin film?
Monocrystalline solar panels live the longest. Most solar panel manufacturers put a 25-year warranty on their monocrystalline solar panels.
Q:Solar water heater manufacturing materials
Flat panel collector in the development of the solar energy industry is unstoppable, not rely on some manufacturers can be strangled misleading. Now many designers of the water supply and drainage designers have been aware of this problem.All glass evacuated solar collector tubes are generally made of high borosilicate 3.3 hard glass, vacuum sputtering process. It can be divided into aluminum nitrogen single target coating process and copper, aluminum, stainless steel three target coating process.
Q:Why are solar panels placed on the roof of houses?
Solar panels are placed on the roof because many times the roof has good exposure to the sun providing the roof is not blocked by trees or something else so that sufficient sunlight wouldn't be absorbed. Also the panels would more likely not get damaged on the roof opposed to being in the yard. If they were mounted on the windows, how could you see? And, the windows could easily break and then what would happen to the panels? Placing the solar panels on the floor would not be practical. A lot of sunlight is needed for the cells to produce electricity and how much goes on the floor? Most roofs are at an angle which could perhaps improve the amount of sunlight the panels would get, and roofs provide a lot of unused space. The roof is the best place. Furthermore, roof solar panels are available now to blend in better with the roof so that they are more pleasing to the eye. Even if you have a small roof, some panels could be placed there provided the roof is not blocked so that the sunlight it gets would be sufficient (about 4 or 5 hours of sunlight a day is needed). And, if you needed addition panels, they could be mounted in your yard as long as the mount was close to your power box and received sufficient sunlight. I applaud your desire to use solar panels. You could possibly save 50 - 90% on your electric bill and help your environment at the same time! A Win - Win situation!!
Q:The meaning of various names
Si seed a specific crystal orientation (seeds, usually a small ingot) rod inserted into the molten state under Si, and slowly pull up the crystal and a seed crystal and the same column to be produced by controlling the process variables to pull the speed to control the crystal column the diameter can be cut into a crystal column. The small lot, wafer is produced
Q:A more efficient solar panel?
yes it is being done. i've seen adds for such a system. on the other hand, if you had a 5 sq in Lens focused on a small cell, and a 5 sq in cell, they'd be about the same. in fact, the cell might be a bit better because (A) there wouldn't be any loss in the Lens, and (B) it might be that the solar cell would use some frequencies to which the Lens was opaque. in addition, the cost of solar cells is dropping, making the cost of the mirrors or lenses uneconomical by comparison.
Q:2V Solar panel directly to 2V inverter...and restult.?
An 300W inverter will draw 25 amps from a car battery but the solar panel will only produce about 4 amps. By drawing too much power with the inverter you lowered the voltage so much in the panels wiring that the amp rating on the internal wiring was exceeded and they melted. Next, time run the panel to a voltage regulator, then the regulator to a car battery, then the battery to the inverter.
Q:Solar water heater has the difference between copper and copper
The utility model relates to a solar water heater, which is a device for converting solar energy into heat energy, which is used for heating water from low temperature to high temperature, so as to meet the requirement of hot water use in people's life and production. According to the structure of the solar water heater is divided into vacuum tube solar water heater and flat type solar water heater, mainly vacuum tube solar water heater, occupy 95% of the domestic market share.
Q:What do you know about solar panels?
How photograph voltaic Cells artwork by using Scott Aldous interior this text a million. introduction to How photograph voltaic Cells artwork 2. Photovoltaic Cells: changing Photons to Electrons 3. How Silicon Makes a photograph voltaic cellular 4. Anatomy of a photograph voltaic cellular 5. power Loss in a photograph voltaic cellular 6. photograph voltaic-powering a house 7. fixing photograph voltaic-capacity themes 8. photograph voltaic-capacity experts and Cons 9. lots greater advice 0. See all actual technology articles you have in all probability considered calculators that have photograph voltaic cells -- calculators that never want batteries, and in specific circumstances do no longer even have an off button. as long as you have sufficient mild, they seem to artwork consistently. you're transforming into considered greater suitable photograph voltaic panels -- on emergency street indicators or call packing packing containers, on buoys, even in parking lots to capacity lights fixtures. whether those greater suitable panels are not so straight forward as photograph voltaic powered calculators, they are accessible, and not that stressful to discover in case you comprehend the place to look. There are photograph voltaic cellular arrays on satellites, the place they are used to capacity the electrical powered systems. you have in all probability additionally been listening to with regards to the photograph voltaic revolution for the final 20 years -- the theory at some point we are able to all use unfastened electricity from the solar. it somewhat is a seductive promise: On a dazzling, sunny day, the solar shines approximately a million,000 watts of power according to sq. meter of the planet's floor, and if we could collect all of that power we could unquestionably capacity our homes and workplaces for unfastened.
Q:how much money do solar panels cost?
There are a lot of factors to consider. Net metering, utility rates, number of hours of daylight, size and orientation of roof or other location. I can tell you I had a 3.74 kwhdc system which reduces my bill by about $200 a month. It cost $26K installed, I received a $0K rebate from my utility and a $2K federal tax credit. Businesses have always been able to get a 30% fed. tax credit, this year everyone gets it. If this is a business you plan on owning for a long time there is no reason why you can't do the install in stages. Of course making sure you are conserving as much energy as possible will also help. Using energy efficient lighting, appliances and electronics, Turning off lights, monitors, computers, printers etc when people go home, sharing printers and other resources, adjusting the thermostat and using natural light can all help reduce your electricity usage.
Q:SOLAR Panels?
I'm in the California Foothills and the island of Mindanao... I have both solar panels (electric and water heating) and a single wind-generator since 2000. We actually sell power to PGE in California and are self-sufficient in Mindanao. NOW, I'm confused with YOUR math... you say the Rep. suggests a monthly savings of $35 (25% of $40) which would be $420 / year. If materials / installation are $8,000 less $2000 tax-credit: it would take 35 years to pay off $6,000 at $420 / year. 980 Kwh/ mo is some pretty heavy usage... I'd suggest trying to reduce that. CFT's, lowering your AC setting, no lights if NOT in room, un-plugging stand-by appliances, and upgrading insulation. At our 2000 sq ft California RANCH we only burn 400 Kwh per month, and that includes an 800 sq ft barn (admittedly we heat with a wood-stove). We have 5, Sanyo 200 watt panels (3kw total) and generate an avg 900 kwh / month. SO, we're selling BACK almost 500 kwh mo. to the grid on the photo-cells alone. The kw wind generator averages another 20 kwh / month. I THINK the company YOU are working with is selling the EXCESS electrical-power back to the power-company behind your back !! GOOD LUCK
