How much solar do I need for a 2000 square foot home?
4.9kW Grid Tie System
With Enphase Microinverters
If you're looking to install a solar power system on your home, to reduce your electric bill, these grid tie systems are a great place to start. So how much power are you currently using on a monthly basis? You'll need to look at your bill to find out. That will tell you how many kilowatt-hours (kWh) you are using each month. Then you simply plug that average monthly number into our Grid Tie Calculator, and off you go! Again, the video to the right will step you through this very simple process.
Now, for the Grid Tie System that we put together for you here - how much power will you get from this system on average, each month? Take a look on map below and find where you live.
NOTE: The image of the solar panels above is representational. The correct panel will always be listed in the table below.

Components of this 4.9kW Grid Tie Solar Power System:
altE's Solar Power Systems include the major components needed for a solar installation. Since each installation is unique, some parts/materials will need to be purchased separately to satisfy the needs of your specific project and local regulations.
1. Photovoltaic Modules (aka solar panels, solar electric panels)
The PV modules are the individual building blocks for providing power from the sun. They are typically made from silicon cells, glass, tedlar, and aluminum. Solar Panels can vary in type, size, shape, and color. The common nominal voltages for panels are 20V and 24V, in order to accomodate the voltage windows of grid tie inverters.
2. Racking/Mounting System for Solar Panels
The mounting system for the solar panels includes the hardware to permanently affix the array to either a roof, a pole, or the ground. These systems are typically made of aluminum and are customized to the mounting surface and the model of module used. It is important to consider distance from roof for flush-type roof mount installations. Restricting airflow under the modules results in higher module operating temperatures that reduce power output. With pole mounts wind loading must be considered and proper civil works must be done with the foundation for the pole as well as the possible addition of supplementary wind supports for the array frame.
3. Combiner Box
A combiner box is an electrical box where series strings of solar panels are then spliced in parallel. This is also the place where the PV series string fuses or circuit breakers are located. This allows the installer to bring the separate strings together and combine them into one positive and one negative conductor, change wire types and leave the area of the modules in conduit. They are usually outside and weather rated, so they can be right next to the array.
4. DC and AC Disconnects
The DC and AC disconnects are manual switch units that are capable of cutting off power to and from the inverter. Some inverters have disconnects integrated into the unit with switches, others can have them integrated into a power panel assembly, and some inverters leave you on your own to provide suitable disconnecting means. The disconnects are used by service personnel or authorized persons (fire/police/electric workers) to disable power from a renewable energy system (in this case PV) so that there are no live electrical parts associated with the inverter, and that no current is going to the grid that could harm utility employees in the event that they are working in your area. Homeowners or authorized personnel can use the disconnects to de-energize a system for maintenance or service.
5. Grid Tie Inverter (Micro Inverter)
The grid tie inverter is the device that takes the energy that the photovoltaic system produces in DC current form and turns it to AC current that is then sent (sold) to the electric grid. These inverters typically have a voltage input range from 100 to 500 volts DC and they convert it into 120 volts AC, 240 volts AC, or 208 volts AC. These inverters are especially sophisticated devices that must conform to special regulations in order to tie into the utility. When the power goes out in your area, it is important to know that the grid tie inverter will not allow power to be sold back to the grid. This is done to prevent electric utility workers from being injured or killed by working on power lines they thought were de-energized. When the power goes out, your power will go out as well. A grid tie inverter will not resume normal operations until the utility grid has established standard conditions for 5 straight minutes within strict parameters.
There are benefits to having a system layout with many small inverters (micro inverters) instead of a single large inverter (string inverter). First, it gives the system reliability by not having a single point of failure. If a module or an inverter is having an issue, it only affects the output of one module, as opposed to the entire system. In a single large inverter system, if one solar module is being shaded, it negatively affects the output of other modules in the system. The micro-inverter decentralizes this so that if one module is being shaded, the output of that particular module is the only one that will drop.
