The word Photovoltaic (PV) comes from the words photo (which means light) and voltaic (which means electricity) therefore in essence a Solar PV works with light turning it to electricity and not necessarily heat. So even in cloudy days your solar panels are still able to produce electricity although it might not be producing at its full potential because it’s not direct light from the sun. As long as it is noon your panels will work that is why you see European countries (which have more cloudy days than sunny days) leading in solar PV investments without an issue of their cloudy rainy weather.
We offer two different types of SWHs namely the low-pressure system and the high-pressure system. The low-pressure system only works when the sun is out and hot, although it has an insulated water storage tank when the sun hasn’t been out for a while the system will unfortunately provide cold water. But with our high-pressure systems whenever the sun is not out the system automatically switches on the heating element that comes with it so that you have an assured supply of hot water everyday no matter what.
Net metering in the context of PV generation is when a household or business (that is an electricity consumer) installs a grid tied solar PV system that supplies (export) back to the grid less than what they purchase (imports) from the municipality or Eskom over a period of 12 months.
Just like an actual footprint, it’s a mark you leave on the environment with every action that releases carbon emissions. Therefore, each and every time fossil fuels (oil, gas or coal) are burnt to release energy and for example produce electricity they also release carbons (CO2) into the atmosphere and the more you use energy that comes from these fossil fuels whether it is in the form of electricity or transportation the bigger your carbon footprint would be. These carbon emissions are undesirable because they are a potential cause to a global catastrophe by means of global warming which is evidently happening.
One carbon credit is equal to one tonne of carbon dioxide, or in some markets, carbon dioxide equivalent gases. Carbon trading is an application of an emissions trading approach. Greenhouse gas emissions are capped and then markets are used to allocate the emissions among the group of regulated sources.
