Home Solar Panel
December 30th, 2009
The Home Solar Panel is built with the same ability to collect the heat from the sun as those that are built commercially, only on a smaller scale. They are usually designed to be more aesthetic and often fitted to the roof with an adjustment made to obtain the best angle for the sun.
There are basically two types that are designed for the use in the home, the PV Home Solar Panel and Thermal Collectors. The PV home solar panel provide electricity to just part, or all of your home, whereas the Thermal panels provide heat, to heat up either the water system, swimming pool or house heating. Both are using a source that comes to you free of charge and will never run out.

So what is a kW and what does kWh mean.
kW simply means kilowatt which is a 1000 Watts.
kWh is a term we use to measure the amount of energy being used in 1 hour.
If you were to be running an appliance in the kitchen like a small 1000 Watt oven for 1 hour then you would use up 1kWh of power. The Electricity Company would then charge you for that 1kWh so depending on your company will depend on the amount you are being charged. The average American home uses 20 kWh of power a day whereas a home that has been designed for very high energy-efficiency will only use approx. 6kWh a day.
So will a Home Solar Panel that is rated at 1kW produce 1kWh of power, not quite. The panel is rated at that but there are a lot of other factors that effect it’s ability to produce.
The home solar Panels rating is what is called Standard Operating Conditions, (SOC) this rating is given to the panel after being tested in a laboratory, however, we all know that the elements in the real world like air temperature, shade, cloudy days, dirt on the panels, these will all have an effect on the production of power.
Generally the Home Solar Panel is designed to produce their rated power output at a temperature of 70 to 80 deg. Fahrenheit, or 21 to 27 deg. Celsius.
So with these natural factors hindering the panel to produce electricity from our sun, as well as the loss through the inverter (approx. 5%) a 1 kWh system will produce an output of approx. 750 Watts.
Here is a chart of what you can expect from your Home Solar Panel System.
1000W (1KW) Solar panel * 6 fitted – will produce an average of 4 kWh of power
Saving around 1.6 Tons of CO2 a year
1500W (1.5KW) Solar panel * 9 fitted will produce an average of 6 kWh of power
Saving around 2.5 Tons of CO2 a year
2100W (2.1KW) panel * 12 fitted – will produce an average of 8.5 kWh of power Saving around 3.5 Tons of CO2 a year
3050W (3.05KW) Solar panel * 18 fitted – will produce an average of 12.5 kWh of power Saving around 5.0 Tons of CO2 a year
So Will your solar system work at night
The answer to that is, the panels will not be converting at night with no sun, but depending on the Solar Energy system you have, you are still able to run your household at night.
These are the higher end systems and yes they are more costly. The reason for this, is the amount of battery storage you have to have and the need for more Solar Panels to charge them. Thereby increasing the overall cost.
And what about cloudy days.
Yes with the advanced technology today the home solar panel will produce while it’s cloudy, however, the production of electricity is less than when it is sunny.
How much energy can I expect from my Home Solar panels.
This will of course depend on a few factors. The size of your installation, where you live, how much sun hours per day do you get, the location of the panels on your property and so on.
Many of the home solar panel systems will create enough energy to run the entire home. Other systems that are smaller can provide power for one or two rooms, or for a workshop etc. they can be designed to what ever size you like if you have the Thermo Collectors installed, you can provide enough heat to heat your swimming pool. So it is important to remember that by using Alternative Solar Energy, the home solar panel system can be customised to suite the size of productivity as well as the budget.
Where is the best place to install my solar panels
You need the home solar panels to be placed in a position to maximise the heat from the sun, to gain the most advantage from it’s resource. You don’t always have to have them on the roof, if the roof has too much shade, pick a spot even in your garden, that has the most sunlight and locate your panels there. You can even have portable solar panels enabling you to move them around. But it is best no matter where you place them, that they are set at the right angle depending on your latitude, to capture the suns rays perfectly.
