|How to calculate the solar system size for your needs
One of the main questions to consider when planning your solar system is how big it needs to be. In other words, how much electricity does it need to generate in order to power your home, or at least to power the most important appliances.
When choosing your solar system size, you first need to calculate how much energy your house uses. Once you have discovered this amount, you can then begin to make use of energy saving techniques to bring the total amount down. It makes sense that the less energy you need to generate, the less amount of money you will need to spend on your solar system.
It is important to remember that almost every device that plugs into a wall socket usually has a label or engraving that tells you how much energy it uses. This is a great place to start, although the amounts given may vary somewhat.
There are three main ways that you can go about calculating how much power your home uses from month to month:
1. Using a simple plug-in-watt-hour meter
2. Installing an in-home energy use monitor
3. Keeping track of your electricity meter over time
Let’s discuss these three approaches in more detail.
Using a simple plug-in-watt-hour meter
These sorts of devices are perfect for measuring how much electricity appliances use, either at a given moment or over a period of time. While this isn’t going to give you a completely accurate reading for your entire home, it will allow you to find out how much energy your most common appliances use each month.
These devices are affordable and easy to use. Simply plug the appliance into the meter, plug the meter into the wall, and the reading will display. Slightly more expensive meters will allow you to store and download the data for closer analysis, as well as providing you with usage graphs, comparisons and predictions.
Using an in-home energy use monitor
In-home energy display meters offer the most accurate readings, making them really useful solar power calculator devices. Besides calculating how much energy your entire house is using at any given moment, as well as how much energy you use per month, home energy meters can also provide you with other valuable information.
Cost of the energy used, as well as an estimate of greenhouse gas emissions are some of the features that make these devices worthwhile.
We recommend using a qualified electrician to install this device. The installation process it typically quick and easy, usually only taking about 30 minutes to complete.
Tracking electricity meter over time
This process may require a little bit more work from your side, but the main advantage is that it is completely free. While you won’t have the benefit of storing the data in nifty ways that compare prices and monthly usage, you will still be able to receive an accurate monthly reading of how much energy your home uses.
The process is simple and rather logical. Take a look at your current reading on your electricity meter and write it down. After certain time periods, whether it is daily or monthly, you can revert back to the meter and jot down the latest reading. Subtracting the first reading from the latest reading will let you know how much energy was used over that time period.
