The design phase is the first of three steps.  Properly planning and laying out your work results in a quality job.

Solar Electric (PV)


.

Do you want to use solar electric panels to lower or even eliminate your electric bill?  Are you tired of energy bills, heat and electric, going up without reason or limitation?  Installing solar electric panels can give you an established predictable rate long into the future.  We will design a solar energy system to meet the unique goals for your application.


There are two types of systems for us to discuss here.  Grid tied systems and Off Grid systems.

Off Grid systems rely on a battery bank to store generated electricity for later use.  This  offers complete independence from "The Power Grid".  During a black-out you would still have power while your neighbors do not.  This independence does however come with a trade off.  The battery system increases your system cost and required maintenance.

 Grid tied systems remain connected to "The Power Grid".  The solar panels generate electricity which if not used by you, will cause your electric meter to spin in reverse.  This is when you are selling your excess power generation to the electric company.  When your system does not meet your requirement you buy from the electric company.  This back and forth system is called 'Net Metering'.  Grid tied systems are less expensive than off grid and do not require the maintenance.

In the Grid Tied system with net metering, the power company essentially becomes a storage and transportation center for electricity.

What components make up a solar electric system?

The system will consist of solar pv modules, mounting frames, inverters, monitoring equipment, safety equipment and utility meters.  Batteries would also be included if you are working with an off grid system.


Considerations and steps to begin:

  • You should gather copies of your electric bill.  This will provide us a detailed understanding of your electric use.
  • Contact GeoSun Design for initial consultation
  • GeoSun Design will perform a site survey.  From the site survey we will consider the optimal location, latitude, tilt and azimuth, shading and weather patterns.
  • If the array is to be placed on a roof, we will need access to inspect the roof for condition, rafter spacing, safety and access, and other considerations.

Once we are done with our site visit and analysis work we will be able to provide you with an initial design report which will clearly explain the output production anticipated from the specified array.

There are a variety of Federal and State tax credits as well as other rebate and loan programs available.  We will help you learn about and understand the details of these programs as part of the process.
