Questions & Answers

Q: Will PV Solar panels work during the winter?

A: Yes. Solar panel manufacturing technology has now advanced to a level that panels will now produce green electricity even on an overcast cloudy day.

Q: What’s the difference between PV and other solar energy technologies?

A: PV solar systems convert solar radiation directly into electricity by means of PV cells made from semiconductor materials.Wet solar systems (water heating), use a solar collector that faces the sun and is used solely for heating water. They are not as efficient as PV solar systems and if the heated water is not used then the energy created is lost.

Q: What happens when I produce more electricity than I need?

A: When your PV system produces more electricity than you need, the surplus will flow back into the national grid. Your electricity supplier will pay you extra for this surplus power, to reduce your future electricity bills.

Q: Why should I consider a PV solar system?

A: PV solar systems are easy to install with minimal disruption and have no moving parts so they are also maintenance free. PV is now a mature technology, is guaranteed at 80% efficient for 25 years plus, creates no pollution and is silent when operating.

Q: What are the disadvantages to using PV solar system?

A: There are no disadvantages. Obviously there is an initial cost, however this is offset by the feed in tariff. The average system should pay for itself in 8 years, it is government backed, index linked and you also reduce your electricity bills. Any savings that you may have at the moment will not produce this return of investment.

Q: Should I change my electricity supplier?

A: There is no need to change your existing electricity supplier unless you want to, and if you do we will help you.

Q: Are Volta Solar Ltd a national company?

A: Yes we are, for domestic installations under 4kW, we are a National Company with depots throughout the United Kingdom.

Q: How long will it take to install my PV solar system?

A: PV systems can be installed and ready to produce electricity in 2-8 weeks from the time the design & schematic have been agreed.

Q: How big a PV solar energy system do I need?

A: The size of solar system you need depends on several factors such as how much electricity you use, how much daylight is available where you are, the size of your roof, and how much you’re willing to invest. After talking through your requirements we will recommend the size of system you use.

Q: Could I install a photovoltaic (PV) system myself?

A: Yes, however unless you are very handy or experienced in home wiring, we suggest using experienced professionals to design and install anything more than the simplest application, for the following reasons:

You have to pay 20% VAT on the PV cells rather than the 5% accredited dealers.
You will not be MCS approved and therefore not eligible for the feed in tariff.
Electricity can be dangerous, you may get hurt!
You may damage your home or appliances during installation.
You would NOT have the correct EL & PL installation insurance in place.

However none of the above is insurmountable

Q: What happens if something goes wrong?

A: All panels come with a 25 year performance warranty so in the unlikely event that you experience problems, Volta Solar Ltd will be on hand to diagnose and resolve your problem. The installation comes with a 10 year warranty so you can be sure your installation will be of the highest standard.

Q: What maintenance and cleaning do the systems need?

A: PV Solar systems are silent in operation, have no moving parts and require very little maintenance. Dust or dirt may cause a power reduction. The modules can be cleaned with a hose and clean water.
