ENG/TECH: The building blocks of solar!

One of the first things I realized about solar PV was that it truly encompasses all forms of engineering and technology! Just think about it! It clearly epitomizes mechanics and electronics, its environmentally-friendly, the integration of buildings and rooftops involves civil and structural studies, and the building process of the solar modules themselves surrounds itself with the use of certain elements and chemicals that produce electricity when facing the sun. This being the first post on design, construction, and installation, I'll keep it short and simple for now.

So in the new millennium, utility-interactive PV systems had just started to open its wings on the world. Only a few inspectors and installers truly knew the codes and requirements involved in the design and execution of PV systems. As costs of PV modules and materials started to decrease, and production of fossil-generated electricity continued to increase, the need for more PV installers and practitioners increased, and actually continues to do so today!! Mounting solar PV systems isn't too hard or complex to learn, but it certainly takes years of experience and practice to master. 

First off, it requires a location that will not be shaded for the most part. It also needs to fulfill structural requirements and tests to that would be fixed or tracked from a certain surface that will be able to withstand wind and earthquake loads, and endure weather over the lifetime of the system. Electrical requirements are also not too complicated, as long as they are securely followed under the NEC regulations for solar PV systems. PV design and layouts may include a variety of installation operations, so the installer and site assessor can submit the appropriate documents and packages for the proposed installation. Finally, building and electrical inspectors need appraisal of PV system simplicity through aesthetic, efficient operation and maintenance of the system. This will have the PV permitting process reasonably streamlined in time so the necessary fees maybe charged, and rebates sent out to consumers.

A Little Catchup!

Hope everyone has been well! After taking off last month, I'm back on with a bang! Lately I've started designing and constructing my own DC-coupled PV solar model used to operate a 12 volt fan. The hours have been long, but its worth it. Its a great way to learn about different elements of design and installation. I'll be posting some pictures as soon as its finished, including the step-by-step process in order of each phase approached. And in case your wondering, the next post will introduce exactly that...design, installation, operation, and maintenance!
