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:Can solar panels be installed on a parking lot or carport?
- Yes, solar panels can be installed on a parking lot or carport. In fact, these locations are ideal for solar panel installations as they provide ample space and can generate clean energy while also providing shade and protection for vehicles. This dual-purpose approach helps maximize the benefits of solar energy and optimizes land usage.
- Q:My solar panel is 24long..It is set at 45deg..the arms are 8quot;long to achieve that angle for winter. I need to get to 7deg for summer..how long will the new arms need to be?..in layman's terms please...thx
- You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav
- Q:Hi, I want to put some solar light in my yard, and wondering if a 00w solar panel could work for a few 3w dc lights....do i need a battery so they run at night, if so how many lights do u think i can run/ also i see elading solar light
- 3 w for 2 hours/night is 36 watt hours. You'll get about 500 watt hours/day from your panel on the average, which for a 2 volt battery is about 40 ampere hours. You can get an 80 amp-hour sealed gel cell battery to charge with this panel (with a suitable charge controller). You want to size your lights so the battery can provide three days of light without discharging it more than 50%, so that's abnout 600 watt-hours/3/36 = about 4 orf 5 lights. Cost for this system woulkd be over $500. The advantage of the self contained light is they use a lithium or nickel battery rather than a lead acid, so it can run totally dead without damage (unmlike a sealed lead-acid battery). That would be a far cheaper way to go. DK
- Q:im trying to experiment with solar panels. so i dont want to buy a huge expensive solar panel if i dont need one.

- Q:Why can't they put solar-panels on the blades and sides of the 300-500 foot tall turbines? Wouldn't this increase effeciency? Therefore, boosting pay-back time, profits, energy-output?
- No. The solar panels would never be balanced. Those blades need to be very balanced. Additionally, how would the solar panels get the power from a rotating blade to the ground? It is better to have separate units. What we ought to be concerned with is having large solar panel farms. These are counter-productive to going green, as they still require long and harmful power transmission lines. Solar panels ought to be put on top of buildings which would be using that power. Any additional power not used could be added to the power grid. For those types of clean energy that are not practical on the roof might get space near the building, keeping the transmission lines as short as possible. Large farms ought to be owned by the nation, keeping the cost of the power to the customer as low as possible. Power companies rip off consumers with their price gouging. It is time to let the burden of making a few rich at the expense of the many end.
- Q:Hi, I am very interested in solar panels and would like to know more.Can someone please give me a basic explanation of how solar panels work?Thank you
- Solar panels are made of many solar cells.solar cell is an electicial device that comverts sun energy directly into electricity by the photovoltaic effect,which is an physic and chemical phenomenon.solar cells are usually connected in series in moodules,creating an additive voltage.
- Q:How do solar panels affect my electricity bill?
- Solar panels can significantly reduce your electricity bill by generating clean and renewable energy from the sun. By harnessing solar power, you can generate your own electricity, thus reducing reliance on the grid and lowering your monthly utility costs. In some cases, solar panels can even result in net metering, allowing you to receive credits or payments for surplus energy that you feed back into the grid.
- Q:Can solar panels be used in areas with high levels of rainfall?
- Yes, solar panels can be used in areas with high levels of rainfall. While excessive water exposure can affect the performance of solar panels in the short term, modern solar panels are designed to withstand different weather conditions, including rain. Proper installation and maintenance can ensure their efficiency and longevity, even in areas with high rainfall.
- Q:How efficient are solar panels when it comes to turning light into energy? If it's not 00%, why? Can it be improved? Also, how do solar panels work, exactly.
- Solar panels are efficient but in case when solar energy is not enough or it’s a cloudy day, then sufficient energy can’t be generated.
- Q:Can solar panels be installed on a restaurant or food establishment?
- Yes, solar panels can definitely be installed on a restaurant or food establishment. In fact, many restaurants and food establishments are increasingly adopting solar energy as a sustainable and cost-effective solution to power their operations. By installing solar panels, these establishments can reduce their carbon footprint and save on energy costs in the long run.
