Solar Electricity For Homes – Getting The Right Design
How To Generate Solar Electricity For Homes
If you are planning to use solar electricity for home power consumption, here are a few important points to designing the system.
1) Find out what is the load in energy for a 24-hour period for your home. Make sure you get the watt-hours, not the watts.
2) Decide what is the the size of the solar array to be used. This will involve some calculation which will determine your DIY home improvement budget.
3) Decide on the battery size.
Basic Design For Home Solar Panels
If you are outsourcing the building of the solar array, the following is a rough estimate that you can take to the system designer to discuss cost and objectives of your renewable energy system. The designer will then fine tune the system based on actual components such as cable size, cable distance, measuring meters etc.
It may be a good idea to start the design based on the worst case scenario, meaning power generation during the least amount of sun coverage but with a rising power demand.
You can use this example. Determine the power load for a continuous 24 x 7 x 365 of a 250 watt light bulb. So the worst case is the month of December and January when the Solar Insolation is at its lowest point.
In some instance, the worst case for the power load is the summer and worst case for the resource is the winter. This will require you to perform two designs and then to select the one system that will carry the load through both summer and winter time.
Using a Fudge Factor
The Fudge Factor is to take into account the inefficiency of your home solar electric system. When you have determined the power load for a 24 hour period, you may want to multiple it by 1.5.
This in effect will increase the power demand by half, hence you will have to design a bigger solar system. Wouldn’t that increase your cost? The answer is, Yes is will. But you will have a system that will truly fulfill your home power requirement.
Why would you want to build a solar array that won’t generate enough electric power for your household?
If you do that, there won’t be enough power during cloudy days which will lead you to use power from the grid. That would have defeated the purpose of using solar electricity for homes.
