Solar system providers will advise you on the size that suits your requirements; this usually depends on the amount of energy needed and other details such as dimensions of the property.
PV systems can cost anywhere between $8,000 and $27,000, depending on the size of system chosen, which is mainly based on the energy consumption required.
Life expectancy of these systems is normally 40 years plus, depending on the type of quality system purchased.
Yes, it is usually possible to attach additional modules to your system; extra inverters may also have to be added to cope with the load enhancement.
No, south is definitely ideal, but southeast or southwest can function will minimal loss of production.
The PV solar system does this for you. The inverter identifies any unused electricity and sends this excess energy to the grid. The electric meter moves backwards, thus crediting the owner's electric bill.
No. PV solar power systems connect straight to your local utility grid.
Yes. Most of this equipment does not weigh an awful lot and most modern buildings are designed to deal with far greater loads. Though, older buildings need to be surveyed and may require structural work for extra support.
You will have to check your local area code requirements.
This, again, depends on the size of your chosen system, as well as the type of company chosen to carry out the installation. Average residential systems may take less than one week whilst larger commercial installations will take slightly longer.
If anything, solar systems are incredibly ideal for businesses. This is because businesses usually consume large amounts of energy, and it is important to keep costs efficient in order to run a successful business. Depending on your local area, commercial users are usually offered great financial program incentives.
Mostly, yes. However, the type of program incentives available depends on your location and whether you are a residential or commercial user.
Solar electric systems have been used by space stations since 1954 and technology has advanced incredibly since then making it an extremely reliable source of energy. Also, PV solar modules usually come with a 25 year warranty.
Yes, it has been used for decades but on a much smaller scale than the US. This is mostly because of the less sunny climates like in Germany and the UK. However, it is quite clear that the use of solar energy is important for conserving the environment and that is why the EU has recently agreed to increase its use of producing electricity from renewable sources such as solar.
