CO2 levels in atmosphere reaching 400ppm for first time in 3 million years

The concentration of carbon dioxide in the atmosphere has reached 399.72 parts per million (ppm) and is likely to pass the symbolically important 400ppm level for the first time.

Historical Weather And Climate Data


PLEASE NOTE: If your data is not found (thru the links below) appearing below, and would like a detailed personal search, you may contact us to select a weather station close to your chosen location

Renewable Energy System Design Tools

To optimise the performance of your system, we need to know the what the weather is like in the area where the system will be installed. Please complete the 3 steps below to begin designing your renewable energy system


Step 1:
Look Up your Country& City for Climate Data & Graphical Data. (Below) You can us the links  or scroll down to view the climate data & graphical data.

 

Step 2: At this stage weather data from the nearest weather station should be obtained.

PLEASE NOTE: 
Solar Irradiation & Wind Speed
Air and Ground Temperature
Humidity and Air Pressure


Step 3: Once you have chosen your nearest (or most appropriate) weather station, you can proceed to design your own wind or solar power system. Choose the type of renewable energy system you wish to design. Please follow this link.  Solar/ Wind Costs & Performance Calculators

 

Grid Connected Solar

Are you connected to the electricity grid?
Use our grid connected system calculator to calculate the cost of a system for your home, electricity savings and greenhouse gas emission reductions.

Do you need electricity in places where it is not available?
Try our Stand Alone Power Systems (SAPS) calculator to determine your remote power requirements. Suitable for remote houses, & buildings, marine, campers, campervans, caravans, 4 x 4 and off-road vehicles, etc.

Online DC cable sizing tool, use this tool to determine thickness of cable required for your system. The right sized cable will give you the best efficiency!

Solar pumping calculator - Use this tool to determine what kind of solar pump you'll need, how much solar power is required, and how much water will be delivered.

Determining Your Electricity Consumption

Two methods for determining energy consumption are available. Calculate Your  Energy Costs
 
Option 1 - look at your current electricity bill

  To determine your energy consumption you can look at your electricity bill and get your average daily energy usage, usually measured in kilowatts (kWh)

  Note: The average household uses about 16 kWh per day

  Option 2 - Custom energy consumption details

 If you do not have your electricity bill, or plan on changing your energy consumption you can fill out the load analysis tables below.

 

Electrical load analysis

 The load analysis will assist you in determining your load and calculating energy use. It lists power requirements (loads) of typical lights and appliances used in the various rooms of your house.

  Correct power ratings (in watts) should be obtained from the nameplates or manufacturer’s literature, or by contacting the manufacturer.

 The total energy consumed per day is calculated by multiplying the rating of the appliances by the number of hours that they are used. It is measured in watt-hours per day.

Add ALL the appliances that you plan to power with this renewable energy system.
Tip: 24 hours = 1440 mins, 12 hours = 720 mins, etc
