System Outputs Power, Energy Carbon

• Solar PV systems are usually referred to in terms
  of the maximum potential power they could
  generate in full sunlight
• Potential power is measured in kilowatt peak
  (kWp)
• The amount of electrical energy that 1kWp will
  generate will vary depending upon the type of
  cells used and the amount of sunlight falling on
  them
• In the UK a 1kWp photovoltaic system will
  generate between 750 850 kWh of electricity per
  annum
• Electricity generated is zero carbon and replaces
  mains electricity that has a carbon footprint of
  0.43kg/kWh

System Sizes

• A 2kWp PV system is an average sized domestic
  system
• 2kWp of PV is typically 12 panels which will
  cover about 16-20 m² of roof area
• A 2kWp system of polycrystalline modules will
  generate about 1500kWh of electricity per annum
  and cut 645 kg of CO2 emissions
• The annual electricity consumption of an average
  house (3 bed/4 person) is 3300kWh per annum so
  fitting a 2kWp PV system will reduce bills by
  about 45

Benefits of PV

• Easy to install
• No bulky internal equipment or layout alterations
• Maintenance free
• Less planning restrictions
• Electricity generation offers highest carbon
  savings
• Long system life
• Proven to work sunshine much more certain than
  wind in an urban environment
