Residential Solar Power

What is residential solar power?

Solar energy for homes is produced by a connected group of photovoltaic modules or panels usually setup as an array on a residential roof. The panels convert solar light into electric current via a 'photo-electric effect', the outcome being DC electric power. This power is fed into an Inverter to convert the current into AC power, usable in a residential household.

Solar Energy Advantages Disadvantages


  • It is delivered everywhere, everyday
  • It is completely free to use, collect and store
  • It is free from transportation costs
  • It is free from pollution
  • It is an unlimited resource
  • It is the most reliable source of energy
  • It is clean power with zero emissions


  • High initial cost
  • Sun is not always available, clouds will reduce production
  • Production of panels creates pollution
  • Corrosion and hail will degrade and damage panels
  • High space requirement for useful energy production
  • Old panel and battery disposal is an issue
Solar 'Off' Grid plan setup

Residential solar power can be "On Grid", where excess energy produced is sold back to the electricity provider.

Your solar power system can also be "Off Grid" where the residence is self sufficient whereby excess energy is saved in batteries and extra energy is provided by a generator or wind power.

Panels need to be positioned to capture the most sun for the most part of the day so need to be firstly facing true north in the Southern hemisphere and true south in the Northern hemisphere. Secondly, the tilt should be equal to your latitude, plus 15 degrees in winter, or minus 15 degrees in summer.
