The Solar Watt – An Important Consideration in Solar Power For Homes

Anyone considering setting up a solar panel for home should at least be aware of what a solar watt is and how it may impact their decision on whether or not to go ahead with implementing their own solar power system at home.

First things first, although the term solar watt sounds complicated, it’s actually not. It actually refers to the amount of electricity that your solar panel system is able to generate at a particular point in time.

However where this becomes important is because it could well impact the size of the solar panel system that you construct, and may even influence your decision on whether to go ahead with your solar energy project for your home.

Although almost everywhere in the world where people live gets sunshine at some point of the day (with seasonal exceptions of course, such as Antartica and countries located close to the Artic) it’s fair to say not all sunshine is created equal. Different parts of the world get different strengths of sunshine, some areas are impacted by pollution that weakens the sunshine and some areas receive varying strengths of sunshine at different times of year.

So what difference does the solar watt make to your project? Well, simply put, the harder it is for you to generate solar watts based on your sunshine strength the larger the size of panel(s) that you will need in setting up your system.

How do you find this out? You want to find out your daily sunshine intensity value, often referred to as insolation value. The insolation value tells you the amount of solar energy on a given surface area in a given time. Most commonly it is reported as watts per square metre.

You can easily find out this value by searching for an insolation map for your area – the internet is loaded with such information on weather sites and such. The higher the value, the smaller your solar panels will need to be. Well, that depends – you may choose to keep the large panels in order to generate the maximum amount of electricity possible, factoring in the ability of the cells to generate electricity (some may be more efficient than others).

Once you know how many watts your system is likely to generate each day you can build your system accordingly. If you are looking to go completely off grid you will need to divide your total daily energy needs by this number.

And that’s it – the solar watt. Simple really. If you want to learn more about solar power for homes and how it can save you significant amounts of money each year then please visit my solar power guidebook reviews
