Solar Electric Panels
On my desk I have a digital monitor that gives me a real time view of the power we are using at home at any time. It also will show the power usage for the day and month. Outside I have my roof solar electric panels in place and also I can view the power output on a digital readout at any given time.
At Mid day today my power generated from the solar panels was 2.7 kilo watts per hour. The total energy being used by the house was .75 kw. To be conservative If you have good sunlight for 8 hours I have generated about 21 kw back into the grid, minus the total of 6 kw use during that time we have a surplus of 15 kw during that 8 hours. If I view this weeks history we are currently using 121 kw per week, and generating 147 kw, pumping about 25 kw back into the grid and getting paid for it.
Obviously this is our model, and elsewhere results could be better or worse, you may use more power than I do or you may use less, you may get more sunlight every day or you may get less. This is just an example of that what you can achieve by installing solar electric panels to your home can do. For us we would usually break about even, sometimes we pay for extra power use and sometimes we get a credit.
This is also based on being hooked up to the national power grid. There is the other option of having your home set up to work on a 12volt system for lighting. This requires having batteries for power storage. This is a totally self sufficient way of using solar energy. I personally have a friend who uses this system; the house is wired for 12 lights, hot water is produced by use of a solar water heater and the stove and refrigerator run on natural gas. He never runs out of power or hot water, even when guests arrive.
So we can see that over a period of 25 years which is the projected life of the solar panels, we will save thousands after our initial investment. The equation can be further improved but the method of how you go about installing your solar panels.
There are three ways to set up your panels.
Buy new and retail from your local supplier. The easy way and for some the only consideration. Drawback, you are paying top dollar.
Diy solar panels. The cheapest option. Make no mistake; diy solar panels are not as good as or better than the commercial equivalents. While this is not a difficult process and can be done by anyone, home built panels will not likely comply with any electrical codes. This type of panel is best left for small hobby type applications
Solar power kits. For my mind these are a great option, readily available and suitable for all different applications, from laptop chargers to solar electric panels for homes. These kits can be a huge cost saving, allowing you to gradually add more panels as you desire.
