Solar PV (solar photovoltaic) systems generate electricity from daylight. They work best on sunny south-facing roofs and can generate around half the electricity you need.
Here's a quick introduction to Solar PV and how you can make changes to save energy and money.
A solar photovoltaic, or solar PV, system generates electricity from daylight. You can use this free electricity in your home instead of using electricity from your energy company and so reduce your energy bills. The government also pays you for the amount of electricity that the panels produce, whether you use the energy or not!
Many people ask WinACC how to pick a good supplier. We can't recommend a supplier but here is a (not complete) list of local photovoltaic suppliers. To be on this, a supplier must meet WinACC's minimum standards.
Here are some points of interest that may help you in your decision making:
Solar thermal systems heat water using sunlight so that your boiler does not have to work as hard. This means your boiler uses less energy. They work best on sunny south-facing roofs and can generate around half of your household’s hot water requirements.
We live in a fairly wet country so in general panels will clean themselves.
If your panels are sheltered, suffer from bird droppings or you live near a busy road, grime may build up and reduce the efficiency of your panels.
Detergents or tap water should not be used to clean solar panels.
